Resumen: La anestesia dental es un tema importante en la práctica cotidiana enlas diversas especialidades odontológicas, motivo por el que nace lanecesidad de hacer una revisión de las técnicas anestésicas actuales. Con base en nuestra experiencia nos dimos cuenta de que la practicidad de utilizar referencias anatómicas confiables nos sirven de guía para obtener una mejor efi cacia al momento de anestesiar el nervio alveolar mandibular. Lo anterior se traduce en menor dolor posterior a la punción, menor dosis anestésica y una profundidad anestésica adecuada en tejidos blandos y duros, del mismo modo nos permite llevar a cabo diversos tratamientos con un margen de seguridad más amplio y disminuir losriesgos de toxicidad. Cabe mencionar que dicha técnica se ha incluido enla práctica clínica cotidiana en nuestra práctica privada en el Postgradode Ortodoncia del Instituto universitario Franco Inglés de México yen el Servicio de Cirugía Oral y Maxilofacial del Centro Médico Lic.Adolfo López Mateos en la ciudad de Toluca, Estado de México.

Dental anesthesia is an important issue in daily practice in the variousdental specialties, which is why the need for a review of the anesthetictechnique arises. Based on our experience, we realized the practicalityof using reliable anatomical references that serve as a guide, to obtaina better effi cacy when anesthetizing the mandibular alveolar nerve,resulting in less pain after puncture, lower anesthetic dose and anadequate anesthetic depth in soft and hard tissues, which allows us tocarry out various treatments with a wider margin of safety and reducethe risks of toxicity. It is worth mentioning that this technique hasbeen included in daily clinical practice in our private practice, in theorthodontic postgraduate course of the Instituto Franco in Mexico andin the oral and maxillofacial surgery service of the Licensed MedicalCenter «Adolfo Lopez Mateos¼ in the City of Toluca, State of Mexico.

Resumen: Objetivo: Determinar las variantes anatómicas producidas entre el conducto dentario inferior y las corticales alveolares superior, inferior, externa e interna en pacientes desdentados con respecto a pacientes dentados posteroinferiores en tomografía axial computarizada (TAC). Métodos: Se estudiaron 15 tomografías en pacientes edéntulos y 15 en pacientes dentados en el sector posteroinferior, de ambos sexos en pacientes con un rango de edad entre los 50 hasta los 65 años. Se midieron en cortes oblicuos a partir del agujero mentoniano realizando 5 cortes posteriores cada 4 milímetros. En cada corte se realizaron mediciones desde el conducto dentario inferior hasta las corticales superior, inferior, interna y externa. Resultados: Se pudo observar que en los pacientes desdentados se hallan diferencias signifi cativas entre las mediciones del conducto dentario inferior y las corticales óseas, con respecto a los pacientes dentados. Conclusión: Según este estudio se pudo comprobar que el hueso sufre mayor resorción en los pacientes desdentados observándose más acentuada la pérdida ósea entre el conducto dentario y las corticales superior e interna con respecto a los pacientes dentados (AU)

Objective: To determine the anatomical variants produced between the mandibular canal and the superior, inferior, external and internal alveolar cortices in edentulous patients with respect to dentate patients posteroinferior in computed tomography (CBCT). Methods: Fifteen tomographies were studied in edentulous patients and 15 in dentate patients in the posteroinferior sector, of both sexes in patients with an age range between 50 and 65 years. They were measured in oblique cuts from the mental foramen making 5 posterior cuts every 4 millimeters. In each cut, measurements were made from the mandibular canal to the upper, lower, internal and external cortices. Results: It was observed that in the edentulous patients there are signifi cant diff erences between the measurements of the mandibular canal and the bone cortical, with respect to the dentate patients. Conclusion: According to this study it was possible to verify that the bone undergoes greater resorption in the edentulous patients, with more marked loss of bone between the mandibular canal and the superior and internal cortices with respect to the dentate patients (AU)

Resumen: This study aimed to present two papers that show the alterations in the dental arch dimensions of children with cleft lip and palate before and after the primary surgeries. The first study aimed to evaluate the dimensional alterations of the dental arches of neonates with unilateral complete cleft lip and palate before and after two different primary plastic surgeries. The sample was composed of 114 dental casts of 57 children, divided into two groups: Group 1 ­ 26 neonates whose lip closure was accomplished at 3 months of life by Millard´s technique and the anterior and posterior palate closure by von Langenback's technique (VL); Group 2 ­ 31 neonates whose lip closure, nose's ala correction, and anterior palate closure were accomplished of life by Millard´s technique, Mcomb's or Skoog's technique, and vomer's flap, respectively at 3 months of life; posterior palate closure was accomplished by VL at 12 months of life. The dental casts were analyzed at two phases: (T1) pre-cheiloplasty and (T2) one year after palatoplasty. The second study aimed to evaluate morphometrically and longitudinally the alterations of the dental arch dimensions of children with cleft lip and palate. The sample was composed by digital dental casts of children with complete cleft lip (Group 1), complete cleft lip and palate (Group 2), and complete cleft palate (Group 3), obtained at pre-cheiloplasty (T1), pre-palatoplasty (T2), and one year after palatoplasty (T3). The measurements of the dental arch dimensions of both studies were performed directly on the digitized models and analyzed by Appliance Designer software. The following dimensions were obtained: intercanine distance, inter-tuberosity distance, anterior arch length, and total arch length. A previously trained and calibrated examiner performed the assessments of both studies. To verify the alterations among groups, t test and ANOVA followed by Tukey was applied. In the first study, no statistically significant differences occurred at pre-cheiloplasty. At one year after palatoplasty, Group 1 had statistically significant greater anterior-posterior arch length (P=0.002) than Group 2. This suggested that the outcomes of the different surgical techniques may cause alterations in the dental arch growth and development of neonates with cleft lip and palate. In the second study, in Group 1, the distances C-C', T-T', and I-TT' were statistically greater at T2 than at T1. In Group 2, the distances C-C' and I-CC' were smaller at T3. T-T' distance decreased and I-TT' distance increased at all phases. In Group 3, the C-C', T-T', and I-TT' distances were statistically greater at T3. The intergroup comparisons showed that C-C' and T-T' distances were statistically greater in Group 1; C-C' and I-CC' distances were statistically smaller in Group 2; and I-TT' distance was statistically greater in Group 3. The longitudinal evaluation of the changes occurred in the dental arches of children with different oral cleft types showed that cheiloplasty and palatoplasty caused the most alterations in the growth and development of the maxillary dimensions of children with complete cleft lip and palate.(AU)

O propósito deste estudo foi apresentar dois artigos que mostram as alterações das dimensões dos arcos dentários de crianças com fissura labiopalatina antes e depois das cirurgias primárias. O primeiro estudo foi proposto para avaliar as alterações dimensionais dos arcos dentários de neonatos com fissura labiopalatina antes e após a realização de duas técnicas distintas de cirurgias plásticas primárias. A amostra foi composta de 114 modelos dentários em gesso de 57 crianças, divididos em dois grupos: Grupo I ­ 26 neonatos, fechamento do lábio realizado aos 3 meses de vida pela técnica de Millard e palato total aos 12 meses, pela técnica de von Langenback (VL); Grupo II ­ 31 neonatos, fechamento do lábio pela técnica de Millard aos 3 meses de vida, correção de asa nasal (técnicas de Mcomb ou Skoog) e palatoplastia anterior com retalho de vômer aos 3 meses. A palatoplastia posterior foi realizada aos 12 meses pela técnica VL. Os modelos foram analisados em 2 fases: (F1) pré-queiloplastia e (F2) 1 ano pós-palatoplastia. No segundo estudo o objetivo foi realizar uma avaliação longitudinal das alterações das dimensões dos arcos dentários de crianças com fissura labiopalatina. A amostra foi composta de modelos digitais de crianças com fissura completa de lábio (Grupo 1), completa de lábio e palato (Grupo 2), e completa de palato (Grupo 3), obtidos nas fases de pré-queiloplastia (Fase 1), pré-palatoplastia (Fase 2), 1 ano póspalatoplastia (Fase 3). As medidas das dimensões dos arcos dentários nos dois estudos foram realizadas nos modelos digitalizados e analisados utilizando software Appliance Designer. As seguintes dimensões foram obtidas: distância intercaninos, distância intertuberosidade, comprimento anterior do arco dentário e comprimento total do arco. Um avaliador previamente calibrado e treinado realizou as avaliações para os dois estudos. Foi aplicado o Teste t e a Análise de Variância, seguida do Teste de Tukey. Para o primeiro estudo não houve diferença estatisticamente significante na fase pré-queiloplastia entre os grupos. Na fase 1 ano pós-palatoplastia houve diferença para o comprimento anteroposterior do arco dentário (p=0,002), entre os grupos, com valores maiores para o grupo I. Para o segundo estudo, no Grupo 1, as distâncias C-C', T-T' e I-TT' apresentaram diferença estatisticamente significante entre a F1 e F2, com aumento na F2. Para o Grupo 2, houve diferença estatisticamente significante em todas as fases avaliadas. As distâncias C-C' e I-CC' apresentaram menor valor na F3, T-T' diminuiu em todas as fases, e I-TT' aumentou em todas as fases. No Grupo 3, as distâncias C-C', T-T' e I-TT' mostraram diferença estatisticamente significante com aumento na F3. Quando avaliadas as medidas entre os grupos e fases, C-C' e T-T' mostraram um valor maior para o Grupo 1. A comparação entre F2 e F3 mostraram para as distâncias C-C' e I-CC' valor menor para o Grupo 2, e I-TT' foi maior para o Grupo 3. As avaliações longitudinais nos arcos dentários mostraram que a queiloplastia e palatoplastia causam maiores alterações de crescimento e desenvolvimento maxilares de pacientes com fissura completa de lábio e palato.(AU)

Resumen: Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were confirmed. The horizontal line which extends between the most prominent point of the lateral and medial margins of patella was defined as a reference line. The distance of branching point of the GAs from the reference line was measured, and the correlations between these points were analyzed. The superior lateral and medial genicular arteries (SLGA and SMGA) were located at + 38.17 ± 3.10 mm and + 32.68 ± 3.83 mm from the reference line, respectively. The middle genicular artery (MGA) was originated from + 7.57 ± 3.98 mm. The inferior lateral and medial genicular arteries (ILGA and IMGA) were located at - 18.46 ± 2.63 mm and - 24.09 ± 3.52 mm, respectively. The branching points of the SLGA changed significantly according to the arterial branching pattern with the MGA. In addition, the branching point of the MGA had positive relationships with that of the IMGA (r = 0.385, p <0.05) and that of the ILGA (r = 0.348, p <0.05), respectively. In this study, topography of the GAs and its anatomical association were demonstrated for the first time in Korean cadavers. Knowledge of the topography about frequent variation would be useful for safe surgery and clinical procedures.

La artroplastía total de rodilla ha aumentado sustancialmente, sin embargo los estudios anatómicos de las arterias geniculares (AGs) en esta región son escasos. El objetivo de este estudio fue identificar los patrones y puntos de ramificación de las AGs y sus relaciones. En 42 miembros inferiores, se identificaron el patrón y los puntos de ramificación de las AGs. La línea horizontal que se extiende entre el punto más prominente de los márgenes lateral y medial de la patela se definió como una línea de referencia. Se midió la distancia entre el punto de ramificación de las AGs y la línea de referencia, y se analizaron las correlaciones entre estos puntos. Las arterias geniculares superiores lateral y medial (AGSL y AGSM, respectivamente) se situaron a + 38,17 ± 3,10 mm y + 32,68 ± 3,83 mm de la línea de referencia, respectivamente, y la arteria genicular media (AGM) se originó a partir de + 7,57 ± 3,98 mm. Las arterias geniculares inferiores lateral y medial (AGIL e AGIM, respectivamente) se localizaron a - 18,46 ± 2,63 mm y - 24,09 ± 3,52 mm, respectivamente. Los puntos de ramificación de la AGSL cambiaron significativamente de acuerdo con el patrón de ramificación arterial con respecto a la AGSM. Además, el punto de ramificación de la AGSM tuvo relaciones positivas con el de la AGIM (r = 0.385, p <0.05) y el de la AGIL (r = 0.348, p <0.05). En este estudio, la topografía de las AGs y su asociación anatómica se demostraron por primera vez en cadáveres coreanos. El conocimiento de la topografía sobre la variación frecuente sería útil para su aplicación en el desarrollo de cirugías y procedimientos clínicos seguros.

Resumen: This study was performed to determine age- and sex-related differences in lip thickness. Lateral cephalometric images of 220 healthy individuals were taken and the thicknesses of the upper and lower lips were measured. The measurements were performed in three different age groups. Our results indicate that the lower lip thickness, as well as the distance between the most anterior point of contact between the upper and lower lips and the most protruding point of the upper incisor teeth, differed between the two sexes. The lips of males were thicker than those of females. Receiver operating curve analysis was performed to determine the cutoff values to differentiate thickness between males and females. Our results showed that knowledge of upper and lower lips thickness in relation to age and sex may be beneficial to forensic anthropologists, to plastic and reconstructive surgeons, and to orthodontists for more detailed examination, effective treatment, and optimised outcomes.

Este estudio se realizó para determinar las diferencias en el grosor de los labios relacionadas con la edad y el sexo. Se tomaron imágenes cefalométricas laterales de 220 individuos sanos y se midió el grosor de los labios superior e inferior. Las mediciones se realizaron en tres grupos de edades diferentes. Nuestros resultados indicaron que el grosor del labio inferior, así como la distancia entre el punto más anterior de contacto, entre los labios superior e inferior y el punto más sobresaliente de los dientes incisivos superiores, difieren entre los dos sexos. Los labios de los hombres eran más gruesos que los de las mujeres. Se realizó un análisis de la curva de operación del receptor para determinar los valores de corte para diferenciar el espesor entre hombres y mujeres. Nuestros resultados demostraron que el conocimiento del grosor de los labios, superior e inferior, en relación con la edad y el sexo puede ser beneficioso para los antropólogos forenses, cirujanos plásticos y reconstructivos y para los ortodoncistas al momento de realizar un examen detallado, e implemantar un tratamiento más eficaz, alcanzando resultados optimizados.

Resumen: Por meio do exame tridimensional de Tomografia computadorizada de feixe cônico (TCFC) é possível avaliar a área de interesse previamente aos procedimentos com maior precisão. As variações anatômicas são estruturas que devem ser consideradas para a realização de cirurgias, como a foramina acessória da região anterior da maxila (FARAM). O objetivo principal do presente estudo foi avaliar a FARAM, em 150 exames de TCFC, obtidas no aparelho ICat Classic®. Por meio do programa ICat Vision® foram mensuradas o diâmetro, a distância da FARAM ao forame incisivo (FARAM-FI), da FARAM ao rebordo alveolar vestibular (FARAM-RAV) e da FARAM a sutura intermaxilar (FARAM-SI). Também foi avaliada a trajetória dos canais ósseos formados a partir da FARAM. Nos pacientes dentados, foram localizados por meio da área dos dentes: incisivo central, incisivo lateral e caninos. Foi realizada a correlação entre a presença da FARAM e o gênero e a idade. Dos 150 exames, a FARAM estava presente em 21 exames (14%). Destes, dez pacientes eram edêntulos na região de interesse de estudo e não foi possível localizar a foramina em relação aos dentes. Nenhum exame apresentou a FARAM relacionada ao incisivo central, em sete estavam relacionadas ao incisivo lateral e em quatro estavam relacionadas ao canino. Nenhum exame apresentou a FARAM bilateralmente, sendo que treze foram localizadas no lado direito e oito do lado esquerdo. O diâmetro médio da FARAM foi de 1,57 ± 0,38 mm. As médias das distâncias de FARAM-RAV foi de 11,65 ± 3,34 mm, FARAM-FI foi de 8,86 ± 2,72 mm e FARAM-SI, foi de 6,37 ± 2,9 mm. A trajetória do canal ósseo mais comum foi ascendente/oblíqua em direção a região anterior do assoalho da cavidade nasal. A correlação entre a presença da FARAM e o gênero foi estaticamente significante para os homens (p=0,055) no teste do qui-quadrado. No entanto, não foi estatisticamente significante para a idade.(AU)

Through cone beam computed tomography (CBCT) is possible to evaluate the region of interest before surgical procedures in tridimensional view. Anatomical variations should be considered for performing surgeries, as the additional foraminas in anterior maxilla (AFAM). The main aim of the present study is evaluate AFAM in 150 CBCT exams, obtained through ICat Classic® device. In ICat Vision® software, the diameter, the distance from the AFAM to the incisive foramen (AFAM-IF), AFAM to the vestibular alveolar ridge (AFAM-VAR) and AFAM intermaxillary suture (AFAM-IS) were measured. It was also evaluated the trajectory of the bony canals related to AFAM. In dentate patients, AFAM was located through the teeth area: central incisor, lateral incisor and canines. The correlation between the presence of FARAM and gender and age was investigated. The AFAM was presented in 21 exams (14%). In the positive exams, 10 patients were edentulous in the region of study interest and it was not possible to locate the foramen in relation to the teeth. Any exam presented the AFAM related to the central incisor, in seven were related to the lateral incisor and in four were related to the canine. Any exam presented the AFAM bilaterally, of which thirteen were located on the right side and eight on the left side. The mean diameter of the AFAM was 1.57 ± 0.38 mm. The distance of the AFAM-VAR 11.65 ± 3.34 mm, AFAMIF was 8.86 ± 2.72 mm and AFAM-IS was 6.37 ± 2.9 mm. The most common bone canal trajectory was upward/ oblique to the anterior region of the floor of the nasal cavity. The correlation between the presence of AFAM and the gender was statically significant for males (p=0.055) in the chi-square test. However, it was not statistically significant for age.(AU)

Resumen: The aim of this study was to assess maxillary, mandibular and glenoid fossa changes after bone anchored maxillary protraction (BAMP) therapy in patients with unilateral complete cleft lip and palate (UCLP). Methods: The experimental group comprised 24 patients with UCLP and maxillary sagittal deficiency with a mean initial age of 11.8 years. Cone-beam computed tomography (CBCT) exams of 24 patients with UCLP taken before (T1) and 18 months (T1) after beginning BAMP therapy were selected from the files of the Hospital of Rehabilitation of Craniofacial Anomalies. CBCTs were superimposed at the cranial base. Three-dimensional displacements of landmarks placed in surface models were quantified and visualized in color-coded maps and semi-transparency superimpositions. Kolmogorov-smirnov test was used to calculate distribution of normality. Paired t test was used to compare cleft and non-cleft sides (p<0.05). Results: A point and non-cleft central incisor displaced toward anterior (1.66mm), inferior (1.21mm) and to the cleft side. Orbitale, Infraorbitale foramen and maxillary first permanent molar displaced similarly toward anterior, inferior and medial direction. The zygoma displaced similarly toward anterior and inferior, however the cleft side showed a significantly greater lateral displacement compared to the non-cleft side. The superior concavity of the glenoid fossa showed symmetrical displacement toward anterior, lateral and superior, while the anterior and posterior eminences showed symmetrical displacements toward anterior, lateral and inferior. The mandible showed an overall symmetrical inferior and posterior displacement except for the medial pole of the condyle, which showed a significantly greater lateral displacement on the cleft side. Conclusions: Maxilla showed an anterior and inferior displacement. The glenoid fossa and the overall mandible symmetrically displaced downward and backward. The zygoma of the cleft side was the only maxillary landmark to show significantly greater lateral displacement than the non-cleft side, as well as the medial pole of the condyle on the cleft side.(AU)

O objetivo deste trabalho foi avaliar as alterações da maxila, mandíbula e fossa glenóide após o tratamento com protração maxilar ancorada em osso (BAMP) em pacientes com fissura unilateral completa de lábio e palato (UCLP). Métodos: o grupo experimental foi composto por 24 pacientes com UCLP e deficiência sagital de maxila com idade inicial de 11,8 anos. Foram selecionados exames de tomografia computadorizada de feixe cônico (CBCT) de 24 pacientes com fissura UCLP realizadas antes e após 18 meses de terapia com BAMP pertencentes ao Hospital de Reabilitação de Anomalias Craniofaciais. Os exames de CBCT foram sobrepostos pela base do crânio. Deslocamentos tridimensionais foram mensurados por meio de pontos colocados em modelos de superfície, bem como foram visualizados em mapas coloridos e sobreposições de semi-transparência. A distribuição de normalidade foi calculada por meio do teste de Kolmogorov-Smirnov. A comparação entre os lados com e sem fissura foi realizada por meio do teste t pareado (p<0.05). Resultados: O ponto A e o incisivo central superior do lado sem fissura deslocaram para anterior (1.66mm), inferior (1.21mm) e para o lado da fissura. Os pontos Orbitário, Forame Infra-orbitário e os primeiros molares permanentes superiores se deslocaram simetricamente para anterior, inferior e medial. O ponto Zigomático deslocou simetricamente para anterior e inferior, porém o lado da fissura apresentou um deslocamento significantemente maior para lateral comparado ao lado sem fissura. A concavidade superior da fossa glenóide apresentou um deslocamento simétrico para anterior, lateral e superior. As eminências anterior e posterior da fossa glenóide apresentaram um deslocamento simétrico para anterior, lateral e inferior. No geral, não houve diferença estatisticamente significante entre os lados com e sem fissura para o deslocamente inferior e posterior da mandíbula. O polo medial do côndilo foi o único ponto em que o lado da fissura apresentou um deslocamento significantemente maior para lateral quando comparado ao lado sem fissura. Conclusões: A maxila mostrou um deslocamento simétrico para anterior e inferior. A fossa glenóide e a mandíbula mostraram um deslocamento simétrico para inferior e para trás. Entretanto, os pontos zigomático e polo medial apresentaram um deslocamento lateral significantemente maior no lado da fissura.(AU)

Resumen: Abstract This study aimed at monitoring the maxillary growth of children with cleft lip/palate in the first two years of life, and to evaluate the effects of primary surgeries on dental arch dimensions. The sample consisted of the three-dimensional digital models of 25 subjects with unilateral complete cleft lip and palate (UCLP) and 29 subjects with isolated cleft palate (CP). Maxillary arch dimensions were measured at 3 months (before lip repair), 1 year (before palate repair), and at 2 years of age. Student’s ttest was used for comparison between the groups. Repeated measures ANOVA followed by Tukey’s test was used to compare different treatment phases in the UCLP group. Paired ttest was used to compare different treatment phases in the CP group. P<0.05 was considered statistically significant. Decreased intercanine distance and anterior arch length were observed after lip repair in UCLP. After palate repair, maxillary dimensions increased significantly, except for the intercanine distance in UCLP and the intertuberosity distance in both groups. At the time of palate repair and at two years of age, the maxillary dimensions were very similar in both groups. It can be concluded that the maxillary arches of children with UCLP and CP changed as a result of primary surgery.

Título: Predictors of success for mandibular repositioning appliance in obstructive sleep apnea syndrome
Fuente: Braz. oral res. (Online);31:e37, 2017. tab, graf.
Idioma: en.
Resumen: Abstract The characteristics of non-obese patients with mild to moderate Obstructive Sleep Apnea Syndrome (OSAS) who will present with a good response to Mandibular Repositioning Appliance (MRA) treatment have not yet been well established in the literature. The aim of this study is to assess whether polysomnographic (PSG), demographic, anthropometric, cephalometric, and otorhinolaryngological parameters predict MRA success in the treatment of OSAS. Forty (40) males with mild and moderate OSAS were assessed pretreatment and 2-months post-treatment after wearing an MRA. Demographic, anthropometric, otorhinolaryngological (ENT), cephalometric, and polysomnographic parameters, including continuous positive airway pressure (CPAP) titrated pressure, dental models, Epworth Sleepiness Scale, quality of life (Short Form SF-36), and mood state (Profile of Mood States – POMS), were assessed. The responders exhibited fewer oropharyngeal alterations, increased upper pharyngeal space, reduced lower airway space, and increased mandibular intercanine width, and they had milder disease. Nevertheless, no predictive factors of MRA success could be found. MRA was more successful among men with a more pervious airway, a larger interdental width and milder OSAS. However, a combined [1] functional and structural assessment is needed to successfully predict the [2] effectiveness of MRA treatment of OSA.

Resumen: The adherence of the overlying tissues to the underlying structures in the face is maintained by the retaining ligaments. True retaining ligaments named orbital, zygomatic and mandibular ligaments are a series of fibrous bands that run from periosteum to the dermis. The tethering effect of true retaining ligaments must be released for achieving a satisfactory movement of facial skin and Superficial Muscular Aponeurotic System (SMAS) during facial rejuvenation procedures. The aim of this study was to define the location of the true retaining ligaments of the face and to discuss their usability as surgical landmarks. The study was made on ten hemi-faces of formaline-fixed cadavers. Dissections resembling face-lift procedures were applied and ligaments were determined. The distances of the ligaments to lateral canthus, tragus and commissure and to the lines from tragus to lateral canthus and commissure were measured. Correlations were investigated statistically. The distances of the zygomatic and mandibular ligaments from the tragus were 66.50±10.78 mm and 114.80±9.76 mm respectively. The distances of the zygomatic ligament from the commissure and the commissure tragus line were 56.30±8.94 mm and 28.40±5.19 mm respectively. The distances of zygomatic and mandibular ligaments from the tragus were strongly correlated with a ratio of 3/5 and there was a strong correlation between the distances of the zygomatic ligament from the commissure and commissure- tragus line with a ratio of 2. The results of this study elucidated the possibility of the use of the true retaining ligaments as surgical landmarks for facial surgery.

La adherencia de los tejidos que recubren a las estructuras subyacentes en la cara se mantiene por los ligamentos de retención. Los ligamentos de retención verdaderos llamados ligamentos orbitales, cigomático y mandibular son una serie de bandas fibrosas que se extienden desde el periostio a la dermis. El efecto de la inmovilización de los verdaderos ligamentos de retención debe ser liberado para lograr un movimiento satisfactorio de la piel del rostro y del SMAS durante los procedimientos de estiramiento facial. El objetivo fue definir la ubicación de los verdaderos ligamentos de retención de la cara para discutir su utilidad como puntos de referencia quirúrgicos. El estudio se realizó sobre diez hemi-caras de cadáveres, fijadas con formalina. Las disecciones se asemejaron a los procedimientos de estiramiento facial, se aplicaron y determinaron los ligamentos. Se midieron las distancias de los ligamentos al canto lateral, trago, comisura y a las líneas de trago a canto lateral y comisura. Las correlaciones fueron analizadas estadísticamente. Las distancias de los ligamentos cigomático y mandibular desde el trago fueron 66,50±10,78 mm y 114,80±9,76 mm, respectivamente. Las distancias del ligamento cigomático a la comisura y la línea de comisura al trago fueron 56,30±8,94 mm y 28,40±5,19 mm, respectivamente. Las distancias de los ligamentos cigomático y mandibular desde el trago estaban correlacionadas de forma importante con una relación de 3/5 y había una fuerte correlación entre las distancias del ligamento cigomático desde la línea de comisura y el trago - con una relación de 2. Los resultados de este estudio han dilucidado la posibilidad de la utilización de los verdaderos ligamentos de retención como puntos de referencia quirúrgicos para la cirugía facial.
