Título: Herida penetrante del cráneo / Skull penetrating wound
Fonte: Rev. cuba. cir;50(2), abr.-jun. 2011. ilus.
Idioma: es.
Resumo: El traumatismo craneoencefálico es común en los servicios de urgencia de instituciones que atienden a pacientes politraumatizados y se ha convertido en un problema de salud para muchos países. El traumatismo penetrante del cráneo ocupa un lugar especial por su baja frecuencia. En este trabajo se presenta el caso de un paciente varón, de 52 años de edad, que sufrió una herida penetrante del cráneo producida por un arma blanca que quedó retenida en la región frontotemporal izquierda. Tras un estudio imaginológico se procedió al tratamiento quirúrgico de urgencia, y el paciente evoluciona satisfactoriamente después de 25 días de hospitalización. En la actualidad se encuentra en tratamiento de rehabilitación por una hemiparesia derecha residual(AU)

The cranioencephalic trauma is common in the emergence centers to care for patients with multiple traumata and it becames in a health problem in many countries. Skull penetrating trauma is located in a special place due to its low frequency. In present paper a case of male patient aged 52 severely skull-injured with penetrating wound caused by a cold steel that remained introduced into the left frontotemporal region. After an imaging study the emergence surgical treatment was applied and patient evolves adequately after 25 days of hospitalization. Nowadays, she is under rehabilitation treatment due to a residual right hemiparesis(AU)

Título: Is the combination of fat grafts and platelet rich plasma effective in rats?
Fonte: Acta cir. bras;31(10):668-674, Oct. 2016. tab, graf.
Idioma: en.
Resumo: ABSTRACT PURPOSE: To investigate if the association of fat grafts and platelet-rich plasma (PRP) improves graft viability in female rats. METHODS: This is an experimental, randomized and blinded study, which involved 47 rats. Fat was harvested from the inguinal region and grafted to the cranial region. The experimental group consisted of PRP-enriched fat grafts (n=22) whilst the control group consisted of fat graft only (n=25). After a 100-day period, the animals were euthanised and the fat grafts were analyzed using scores from 0 (absent) to 4 (abundant), in optical microscopy by two independent and blinded pathologists. RESULTS: Regarding fat graft cell viability, the PRP group scored moderate/abundant in 63% of cases and the fat graft only group scored absent/slight in 72% of cases (p=0.03). The PRP group also presented lower fat necrosis scores when compared to the fat graft only group (p=0.03). Tumors (dermoid cysts) within the fat grafts were observed in three animals in which the grafts were mixed with PRP. CONCLUSION: Platelet-rich plasma improves the viability and integration of fat grafts in rats, but more studies are needed to fully understand the exact mechanisms that lead to this improvement and assess the safety of the method for use in humans.

Título: Simvastatin and biphasic calcium phosphate affects bone formation in critical-sized rat calvarial defects
Fonte: Acta cir. bras;31(5):300-307, May 2016. tab, graf.
Idioma: en.
Resumo: ABSTRACT PURPOSE: To investigate the effects of locally applied simvastatin plus biphasic calcium phosphate (BoneCeramic(r)) or collagen sponge on bone formation in critical-sized bone defects. METHODS: Thirty defects of 5mm in diameter were created bilaterally with a trephine bur in the calvariae of fifteen Wistar rats. The defects were divided into five groups: group 1 - control, no treatment; group 2 (BoneCeramic(r)); group 3 (BoneCeramic(r) + 0.1mg simvastatin); group 4 (collagen sponge); and group 5 (collagen sponge + 0.1mg simvastatin). After eight weeks the animals were euthanized and their calvariae were histologically processed. Hematoxylin and eosin-stained sections were subjected to histological and histomorphometrical analyses. The area of newly formed bone was calculated and compared between groups. RESULTS: The greater amount of a bone-like tissue was formed around the carrier in group 3 (BoneCeramic(r) + 0.1mg simvastatin) followed by group 2 (BoneCeramic(r)), and almost no bone was formed in the other groups. Group 3 was significantly different compared to group 2, and both groups were significantly different compared to the other groups. CONCLUSION: Simvastatin combined with BoneCeramic(r) induced significantly greater amounts of newly formed bone and has great potential for the healing of bone defects.

Título: Effects of a buried magnetic field on cranial bone reconstruction in rats
Fonte: J. appl. oral sci;24(2):162-170, Mar.-Apr. 2016. tab, graf.
Idioma: en.
Projeto: Rio Grande do Sul Research Foundation.
Resumo: ABSTRACT The understanding of bone repair phenomena is a fundamental part of dentistry and maxillofacial surgery. Objective The present study aimed to evaluate the influence of buried magnetic field stimulation on bone repair in rat calvaria after reconstruction with autogenous bone grafts, synthetic powdered hydroxyapatite, or allogeneic cartilage grafts, with or without exposure to magnetic stimulation. Material and Methods Ninety male Wistar rats were divided into 18 groups of five animals each. Critical bone defects were created in the rats’ calvaria and immediately reconstructed with autogenous bone, powdered synthetic hydroxyapatite or allogeneic cartilage. Magnetic implants were also placed in half the animals. Rats were euthanized for analysis at 15, 30, and 60 postoperative days. Histomorphometric analyses of the quantity of bone repair were performed at all times. Results These analyses showed significant group by postoperative time interactions (p=0.008). Among the rats subjected to autogenous bone reconstruction, those exposed to magnetic stimulation had higher bone fill percentages than those without magnetic implants. Results also showed that the quality of bone repair remained higher in the former group as compared to the latter at 60 postoperative days. Conclusions After 60 postoperative days, bone repair was greater in the group treated with autogenous bone grafts and exposed to a magnetic field, and bone repair was most pronounced in animals treated with autogenous bone grafts, followed by those treated with powdered synthetic hydroxyapatite and allogeneic cartilage grafts.

Resumo: La influencia de la función respiratoria en el desarrollo de estructuras orofaciales y postura craneocervical ha sido ampliamente discutida. El objetivo del estudio fue comparar valores cefalométricos de la región craneocervical e hioidea en sujetos con respiración nasal y oral. Se incluyeron sujetos de entre 18 y 27 años, de ambos sexos, donde 20 presentaban diagnóstico de respiración oral y 20 no presentaban esta alteración; mediante telerradiografía lateral de cabeza y cuello se realizó análisis cefalométrico craneocervical de Rocabado y aplicación de la técnica de Penning, obteniendo medidas craneocervicales e hioideas, dimensión anterior nasofaríngea y curvatura cervical. Para el análisis estadístico se utilizó la prueba de normalidad Shapiro-Wilk y la prueba T para muestras independientes, considerando un valor de p <0,05 para obtener diferencias significativas; en aquellos parámetros en donde no se presentó distribución normal se aplicó la prueba U de Mann-Whitney. No se encontraron diferencias significativas entre los grupos de estudio y los valores cefalométricos analizados, a excepción de la distancia entre la base del hueso occipital y el arco posterior del atlas (p=0,03). Existen limitadas diferencias cefalométricas entre sujetos con respiración oral y respiración nasal, no asociándose el espacio aéreo nasofaríngeo con las modalidades de respiración estudiadas. Deben ser consideradas condiciones de morfología facial o mandibular, para determinar más adecuadamente la influencia de los parámetros cefalométricos en el diagnóstico del modo respiratorio en estudios futuros.

The influence of respiratory function on the development of orofacial structures and craniocervical posture has been widely discussed. The objective of the study was to compare cephalometric values of the craniocervical and hyoid region in subjects with nasal and oral respiration. Subjects between 18 and 27 years of age, of both sexes, were included, where 20 presented oral breathing diagnosis and 20 did not present this alteration; using lateral telerradiography of the head and neck, craniocervical cephalometric analysis was performed of Rocabado and Penning technique was applied, obtaining craniocervical and hyoid measurements, anterior nasopharyngeal dimension and cervical curvature. For the statistical analysis we used the Shapiro-Wilk normality test and the T test for independent samples, considering a value of p <0.05 to obtain significant differences; in those parameters where no normal distribution was presented, the MannWhitney U test was applied. No significant differences were found between the study groups and the cephalometric values ??analyzed, except for the distance between the base of the occipital bone and the posterior arch of the atlas (p=0.03). There are limited cephalometric differences between subjects with oral breathing and nasal breathing, with no association of the nasopharyngeal air space with the breathing modalities studied. Conditions of facial or mandibular morphology should be considered in order to determine more adequately the influence of cephalometric parameters in the diagnosis of the respiratory mode in future studies.

Título: Treatment of Craniodiaphyseal Dysplasia Presenting with Chiari Type-I
Fonte: Arq. bras. neurocir;35(3):228-233, 20/09/2016. ilus.
Idioma: en.
Resumo: Objective Chiari malformation type-I (CM-1) is described radiographically as a simple displacement of the cerebellar tonsils at least 5 mm below the foramen magnum (FM). If CM-1 exists due to hyperostosis of the cranial bones, the authors were not able to determine a common consensus for the treatment of CM-1 and syringomyelia. Methods A 31-year-old-female presented to our hospital with bilateral facial paralysis, hypoesthesia and motor loss of the extremities. The patient had bilateral gag reflex loss, phonation disorder and dysarthric speaking. Sensory and motor deficits were available at the bilateral upper and lower extremities. The skeletal radiographs revealed extensive thickening and sclerosis of the calvarial and facial bones, moderate widening and sclerosis of the clavicles and ribs, and that the internal auditory canal (IAC) and the optic foramen (OF) were narrowed. CM-1 and syringomyelia secondary to the small posterior fossa were due to calvarial hyperostosis. The patient underwent posterior fossa decompression and duraplasty. In addition, a syringosubarachnoid shunt was placed at the level of C7-T1. The symptoms of lower cranial nerve palsy and motor loss were recovered, but the symptoms of the foraminal stenosis, such as visual and auditory losses and facial paralysis were not recovered in any way. Conclusion We described in this case report CM-1 as a late complication of craniodiaphyseal dysplasia (CDD), and the difficulties in its treatment. In the treatment of these patients with CDD, posterior fossa decompression and syringosubarachnoid shunting are necessary, in spite of all the risks of these procedures.

Objetivo A malformação Chiari tipo-I (MC-1) é descrita radiograficamente como um simples deslocamento da tonsila cerebelar de pelo menos 5 mm abaixo do forame magno (FM). Se houve MC-1 em função da hiperostose dos ossos do crânio, os autores não foram capazes de determinar um consenso para o tratamento de MC-1 e siringomielia. Métodos Paciente de 31 anos deu entrada com paralisia facial bilateral, hipoestesia e perda motora das extremidades. A paciente apresentou perda de reflexo de vômito bilateral, desordem fonética e disartria. Deficiência motora e sensorial foram identificadas em ambas as extremidades superiores e inferiores. Radiografias do esqueleto revelaram extensa espessamento e esclerose dos ossos calvários e faciais, ampliação moderada e esclerose das clavículas e costelas, além de estreitamento do canal auditivo interno (CAI) e do forame ótico (FO). A MC-1 e siringomielia secundária à pequena fossa posterior ocorreram devido à hiperosteose calvarial. A paciente foi submetida a descompressão da fossa posterior e duroplastia. Somado a isso, um shuntsiringo-subaracnóideo foi colocado na altura da C7-T1. Os sintomas de paralisia donervo craniano inferior e a perda motora foram recuperados, mas os sintomas de estenose do forame, como por exemplo perdas auditivas e visuais, ou paralisia facial, não foram recuperados em nenhum nível. Conclusão descrevemos neste relato de caso a MC-1 como uma complicação posterior da displasia craniodiafisária (DCD), além das dificuldades em seu tratamento. No tratamento desta paciente com DCD, são necessários a descompressão da fossa posterior e o shunt siringo-subaracnóideo, apesar de todos os riscos neste procedimento.

Resumo: RESUMEN: Hace aproximadamente once mil años el ser humano pasó de alimentarse de los animales que cazaba o pescaba y los frutos y plantas que recolectaba, a aquellos que podía crecer a voluntad mediante la agricultura. Este cambio alteró dramáticamente la forma de la cabeza ósea y particularmente de la cara, que se hizo más grácil, y además se redujo el aporte de nutrientes claves. Con la industrialización, hubo un gran deterioro de la salud oral. Al abandono de una dieta cazadora recolectora incluso se le ha atribuido el origen de maloclusiones dentales, debido a la reducción del estrés masticatorio y con ello un menor tamaño relativo del maxilar y la mandíbula respecto a los dientes. Hoy en día, existiendo una mayor conciencia de la población respecto de sus cuidados y de su entorno, la adopción de dietas que excluyen cierto tipo de alimentos como los animales ha ganado adeptos. La dieta vegetariana presenta varias características que pueden afectar el metabolismo general y el óseo en particular, de manera similar a como lo hizo la agricultura en el pasado. La presente revisión busca analizar los cambios de la dieta humana, del punto de vista nutricional y mecánico y cómo estos afectaron la forma de la cara. Esto con el objetivo de comprender los posibles efectos de la introducción de alimentaciones de tipo restrictivas, como la vegetariana, en el organismo y particularmente en la anatomía facial.

SUMMARY: Approximately eleven thousand years ago humans beings went from feeding on animals they hunted or fished and fruits and plants they gathered, to crops they could grow through agriculture. This change dramatically altered the shape of the skull, particularly the face, which became more gracile, and also reduced the contribution of key nutrients. Along with industrialization, there was great deterioration of oral health. Leaving behind the hunter-gatherer diet has even been attributed to the origins of dental malocclusions, as masticatory stress was reduce, and reducing the size of the maxilla and mandible with respect to the teeth. Nowadays, there is greater awareness in the general population regarding personal care and their surroundings. Diets that exclude certain types of foods such as animal products are becoming more prevalent. The vegetarian diet has several characteristics that can affect metabolism, particularly the bones, as did the change from hunter-gatherer to agriculture in the past. The present review seeks to analyze the changes of the human diet, from the nutritional and mechanical point of view and how these have affected the shape of the face. This in order to understand the possible effects of the introduction of restrictive type feeds, such as the vegetarian diet in the body, particularly in facial anatomy.

Título: Effects of vacuum sealing drainage on the treatment of cranial bone-exposed wounds in rabbits

Idioma: en.
Projeto: Army Medical and Health Care Research Fund.
Resumo: This study was designed to assess the efficacy of vacuum sealing drainage (VSD) on skull exposure wounds in rabbits and to investigate the underlying mechanism of the process. Full-thickness excisional circular wounds 2×2 cm with or without periosteum involvement were created in 88 New Zealand white rabbits (mean body weight: 3.0±0.65 kg). Animals were randomly divided into 4 groups: periosteum-intact wounds treated with traditional dressing (p+control), periosteum-intact wounds treated with VSD (p+VSD), periosteum-lacking wounds treated with traditional dressing (p-control) and periosteum-lacking wounds treated with VSD (p-VSD). The wounds treated with traditional dressing were covered with Vaseline gauze, while VSD treatment was accompanied with continuous -120 mmHg pressure. Finally, wound tissues were harvested for analysis of hydroxyproline content and histologic detection. VSD hastened the wound healing process significantly (P<0.05) compared to the corresponding control groups. VSD alleviated the inflammation reaction, accelerated re-epithelialization and facilitated the organization of collagen fibers into neat rows. During the wound healing process, the hydroxyproline content increased overtime [i.e., postoperative days (POD) 7, POD 10 and POD 15] in all four groups, and it peaked in the p+VSD group. VSD also promoted angiogenesis via increasing number and quality of collagen. We concluded that VSD can promote healing in bone-exposed wounds via increasing hydroxyproline content and vessel density, reducing inflammatory responses and generating ordered collagen arrangement.

Resumo: O crânio representa o segmento com conspícuas adaptações que, nos lagartos, podem ser conservativas ou impulsionadas por pressões seletivas. Objetivando subsidiar o conhecimento morfológico dos répteis, fornecemos uma descrição detalhada dos ossos que formam o neurocrânio de Iguana iguana iguana com base na análise de três esqueletos secos de espécimes adultos. O crânio da referia espécie possui características basais entre os lagartos sem o fechamento das aberturas cranianas e formato geral triangular. As estruturas ósseas que formam a base craniana apresentam muitas fusões, principalmente no assoalho. Na face caudal o exoccipital e o opistótico estão fundidos e formam o otoccipital, que contribui para a formação dos terços laterais do côndilo occipital. A parte central do côndilo é formada pelo supraoccipital. Fusões e estruturas esqueléticas presentes em Iguana são similares aos demais lagartos. Não foram descritas autapomorfias no neurocrânio para esta espécie.(AU)

Skull represents the segment with conspicuous adaptations that, in lizards, may be conservative or promoted by selective pressures. The aim of assisting the morphological knowledge of reptiles, we provide a detailed description of the neurocranium of Iguana iguana iguana based on analysis of three dried adult skeletons. The skull of this species has basal characteristics in lizards without closure of cranial openings and general triangular shape. Bony structures that form the caudal base have many fusions, especially on the floor. In the caudal face the exoccipital and the opisthotic are fused and form the otooccipital, which contributes to the formation of the lateral part of the condyle. The central part is formed by the condyle supraocciopital. Fusions and skeletal structures in Iguana are similar to other lizards. There are no autopomorphies in the neurocranium for this species.(AU)

Título: Structural and mechanical characterization of custom design cranial implant created using additive manufacturing
Fonte: Electron. j. biotechnol;29:22-31, sept. 2017. ilus, tab, graf.
Idioma: en.
Resumo: Background: Reconstruction of customized cranial implants with a mesh structure using computer-assisted design and additive manufacturing improves the implant design, surgical planning, defect evaluation, implant-tissue interaction and surgeon's accuracy. The objective of this study is to design, develop and fabricate cranial implant with mechanical properties closer to that of bone and drastically decreases the implant failure and to improve the esthetic outcome in cranial surgery with precision fitting for a better quality of life. A customized cranial mesh implant is designed digitally, based on the Digital Imaging and Communication in Medicine files and fabricated using state of the Art-Electron Beam Melting an Additive Manufacturing technology. The EBM produced titanium implant was evaluated based on their mechanical strength and structural characterization. Results: The result shows, the produced mesh implants have a high permeability of bone ingrowth with its reduced weight and modulus of elasticity closer to that the natural bone thus reducing the stress shielding effect. Scanning electron microscope and micro-computed tomography (CT) scanning confirms, that the produced cranial implant has a highly regular pattern of the porous structure with interconnected channels without any internal defect and voids. Conclusions: The study reveals that the use of mesh implants in cranial reconstruction satisfies the need of lighter implants with an adequate mechanical strength, thus restoring better functionality and esthetic outcomes for the patients.
