Título: Otobone ®: Three-dimensional printed Temporal Bone Biomodel for Simulation of Surgical Procedures
Fonte: Int. arch. otorhinolaryngol. (Impr.);23(4):451-454, Out.-Dez. 2019. ilus.
Idioma: en.
Resumo: Introduction: The anatomy of the temporal bone is complex due to the large number of structures and functions grouped in this small bone space, which do not exist in any other region in the human body. With the difficulty of obtaining anatomical parts and the increasing number of ear, nose and throat (ENT) doctors, there was a need to create alternatives as real as possible for training otologic surgeons. Objective: Developing a technique to produce temporal bone models that allow them to maintain the external and internal anatomical features faithful to the natural bone. Methods: For this study, we used a computed tomography (CT) scan of the temporal bones of a 30-year-old male patient, with no structural morphological changes or any other pathology detected in the examination, which was later sent to a 3D printer in order to produce a temporal bone biomodel. Results: After dissection, the lead author evaluated the plasticity of the part and its similarity in drilling a natural bone as grade "4" on a scale of 0 to 5, in which 5 is the closest to the natural bone and 0 the farthest from the natural bone. All structures proposed in the method were found with the proposed color. Conclusion: It is concluded that it is feasible to use biomodels in surgical training of specialist doctors. After dissection of the bone biomodel, it was possible to find the anatomical structures proposed, and to reproduce the surgical approaches most used in surgical practice and training implants (AU)

Idioma: es.
Resumo: El tratamiento quirúrgico del vértigo se puede dividir en dos grandes grupos: no ablativos y ablativos, dentro de éstos últimos se encuentra la laberintectomía quirúrgica, técnica con la cual se produce cofosis. Su principal indicación es la sintomatología vestibular periférica invalidante, unilateral, que no mejora con medidas farmacológicas ni con terapia psiquiátrica, asociado a hipoacusia sensorioneural severa a profunda. Existen dos tipos de abordajes para realizar la laberintectomía quirúrgica: transmastoidea y transcanal, siendo la primera el gold standard para eliminar la función vestibular. Se presentarán dos casos clínicos de pacientes sometidos a estos procedimientos, uno por vía transmastoidea y otro por vía transcanal.

The surgical treatment of vertigo can be classified into two main groups: non-ablative and ablative. The surgical labyrinthectomy is an ablative treatment in which no hearing is preserved. Its main indication is the disabling peripherical and unilateral vestibular symptoms that do not improve with pharmacological measures or with psychiatric therapy, in patients with severe to profound sensorineural hearing loss. There are two types of approaches for labyrinthectomy, transmastoid and transcanal, the first is the gold standard to eliminate the vestibular function. Here, we present two cases of patients undergoing these procedures, one by transmastoid approach and the other by transcanal approach.

Título: Rhinoplasty Complications and Reoperations: Systematic Review
Fonte: Int. arch. otorhinolaryngol. (Impr.);21(1):97-101, Jan.-Mar. 2017. tab, graf.
Idioma: en.
Resumo: Abstract Introduction This article is related to complications of rhinoplasty and its main causes of reoperations. Objectives The objective of this study is to perform a systematic review of literature on complications in rhinoplasty. Data Synthesis The authors conducted a survey of articles related to key terms in the literature by using three important databases within 11 years, between January 2002 and January 2013. We found 1,271 abstracts and selected 49 articles to this review. Conclusion Themain results showed that the number of primary open rhinoplasty was 7902 (89%) and 765 closed (11%) and the percentage of reoperations in primary open complete rhinoplasties was 2.73% and closed complete was 1.56%. The statistical analysis revealed a value of p = 0.071. The standardization of terms can improve the quality of scientific publications about rhinoplasty. There is no difference between primary open or closed rhinoplasty techniques in relation to reoperations.

Título: Interventions in the Alteration on Lingual Frenum: Systematic Review
Fonte: Int. arch. otorhinolaryngol. (Impr.);20(3):275-280, July-Sept. 2016. tab, ilus.
Idioma: en.
Resumo: Abstract Introduction Altered lingual frenum modifies the normal tongue mobility, which may influence the stomatognathic functions, resulting in anatomical, physiological and social damage to the subject. It is necessary that health professionals are aware of the process of evaluation, diagnostics and treatment used today, guiding their intervention. Objective To perform a systematic review of what are the treatment methods used in cases of lingual frenum alteration. Data Synthesis The literature searches were conducted in MEDLINE, LILACS, SciELO, Cochrane and IBECS, delimited by language (Portuguese, English, Spanish), date of publication (January 2000 to January 2014) and studies performed in humans. The selection order used to verify the eligibility of the studies were related to: full text availability; review the abstract; text analysis; final selection. Of the total 443 publications, 26 remained for analysis. The surgical approach was used in all studies, regardless of the study population (infants, children and adults), with a range of tools and techniques employed; speech therapy was recommended in the post surgical in 4 studies. Only 4 studies, all with infants, showed scientific evidence. Conclusion Surgical intervention is effective for the remission of the limitations caused by the alteration on lingual frenum, but there is a deficit of studies with higher methodological quality. The benefits of speech therapy in the post surgical period are described from improvement in the language of mobility aspects and speech articulation.

Resumo: Abstract Introduction Unilateral labyrinthectomy and intra-tympanic gentamycin have been employed in the treatment of Ménière's disease, but the efficacy of these techniques has not been well established. Objective The objective of this study is to measure the time course of recovery from a unilateral labyrinthectomy either after ipsilateral topical treatment with gentamicin to the inner ear or without the previous insult. Methods Twenty-nine adult Mongolian gerbils were randomized into two experimental groups. Group 1 (n=17) received a right ear gentamicin drug-induced lesion by unilateral labyrinthectomy (UL). Group 2 (n=12) only received a right unilateral labyrinthectomy lesion. We measured the horizontal vestibulo-ocular responses in gerbils before and after the lesion. The gerbils received an angular acceleration stimulus and their eye movements were recorded. Results The gentamicin lesion resulted in a quicker recovery. Experimental groups underwent a similar time course of recovery. Statistical analysis showed no significant difference between the two groups. Both groups displayed adaptation to the lesion by day 21, but long-term compensation did not completely revert to the original pre-lesion state. Conclusions In a lesion requiring both static and dynamic compensation as in UL, the need for a static compensation may alter pre-existing compensation from a previous dynamic insult and require a new compensation. A previous lesion and adaptation is not preserved for a second lesion and the subject has to re-compensate. Therefore, surgical treatment in Meniere's disease such as UL can be considered without prior gentamicin treatment. Static and dynamic compensations do not appear to be as independent as previous studies have suggested.

Título: Non-mastoidectomy Cochlear Implant Approaches: A Literature Review
Fonte: Int. arch. otorhinolaryngol. (Impr.);20(2):180-184tab.
Idioma: en.
Resumo: Abstract Introduction Posterior tympanotomy approach for cochlear implant (CI) surgery, has been the most commonly used worldwide with current 0.7% rate of facial nerve injury. Non-mastoidectomy CI approaches include the suprameatal approach (SMA) and its modifications, the transcanal approach and its modifications and the pericanal approach for electrode insertion. Objectives The objective of this study was to review the literature regarding nonmastoidectomy CI approaches. Data Synthesis A search was performed in the LILACS, MEDLINE, SciELO, PubMed databases and Cochrane Library in February 2015, and the key words used in the search were CI, SMA, transcanal approach, pericanal approach, or electrode extrusion. About 30 studies that met the criteria described in "Study Selection" were read in full. The studies showed 1014 patients that underwent CI by SMA or its modifications, 266 CI patients treated by transcanal approach or its modifications, and 15 patients implanted by the pericanal approach. Reported complication with SMA was 99 (9.8%) minor and 13 (1.3%) major. With transcanal, there were 24 complications; 19 (7.1%) minor and 5 (1.9%) major. No post-operative complication was reported in pericanal approach. Studies showed no reported facial nerve paresis or paralysis in all non-mastoidectomy approaches. Conclusion Complications rates with non-mastoidectomy approaches are similar to those found in the mastoidectomy approach. Thus, non-mastoidectomy approaches may be an alternative in cases where the conventional mastoidectomy approach is difficult to perform. It would be helpful for CI surgeons to become familiarized with these approaches.

Título: Medida do grau de correção das orelhas proeminentes utilizando algoritmo de tratamento padronizado / Assessment of the degree of correction of prominent ears using a standardized treatment algorithm
Fonte: Rev. bras. cir. plást;28(4):570-576, july-sept. 2013.
Idioma: en.
Resumo: The goal of aesthetic otoplasty is the correction of ear deformities by creating harmonious and symmetrical external ears, without visible scars. Otoplasty techniques based on the excision of postauricular skin are associated with high recurrence rates. Modern otoplasty is based on cartilage-cutting and cartilage-sparing techniques, alone or in combination, which lead to lower recurrence rates. Objective: We evaluated the efficacy of otoplasty combined with other techniques in the correction of ear deformities, based on a modified version of the "algorithm for otoplasty at the Craniofacial Center at Texas Children's Hospital". Methods: Forty patients, who underwent otoplasty for prominent ears in our institution between March and September of 2009, were prospectively assessed. The mastoid-helix distance was measured preoperatively (baseline) and at 1, 3, and 6 months postoperatively. Results: The most common deformities were scaphoconchal angle greater than 90° (51.3%, 41/80 ears) and conchal hypertrophy > 2.5 cm (46.3%, 37/80 ears). Recurrence occurred in 2 (5%) patients and partial stenosis of the ear canal in 1 (2.5%). Significant reductions in the mastoid-helix distance were observed at the three time points compared with baseline (P
O objetivo da otoplastia estética é a correção de deformidades da orelha, criando orelhas externas harmoniosas e simétricas. As técnicas de otoplastia, baseadas na excisão da pele pós-auricular, estão associados com a recorrência elevada. A otoplastia moderna é baseada nas técnicas de ressecção e/ou modelagem da cartilagem, que levam que menores taxas de recorrência. Objetivo: Foi avaliada a eficácia da otoplastia com técnica combinada na correção de deformidades da orelha, baseado numa versão modificada do "algoritmo para otoplastia", na Centro Craniofacial do Hospital Infantil do Texas". Método: Quarenta pacientes submetidos à otoplastia por orelhas proeminentes, entre março e setembro de 2009, foram avaliados prospectivamente. A distância mastoide-hélice foi medida no pré-operatório e após 1, 3 e 6 meses após a cirurgia. Resultados: As deformidades mais comuns foram ângulo escafo_concha I maior que 90° (51,3%, 41/80 orelhas) e hipertrofia de concha> 2,5cm (46,3%, 37/80 orelhas). Reduções significativas na distância mastoide_hélice foram observadas nos três períodos em comparação com os valores basais (P

Título: Descrição do ponto de Sundfeld-Reis para correção do eixo auricular e polo superior da orelha em otoplastia: nota prévia / Sundfeld-Reis suture for the correction of auricular axis and ear upper pole using otoplasty: preliminary note
Fonte: Rev. bras. cir. plást;28(3):493-498, jul.-set. 2013. ilus.
Idioma: en; pt.
Resumo: Prominent ears are among the most frequent anomalies that affect the head and neck regions and present with conchal disproportionality and/or the lack of an antihelix curvature. A wide spectrum of techniques for the correction of these deformities has been published; the most commonly cited are the techniques from Pitanguy, Converse, Stenvers, Stenstroem, Mustardé, Furnas, and Horlock. All of these techniques seek to restore facial harmony with proportional scaling of the pinna, a suitable cephaloauricular angle, and natural curvature of the antihelix. After reviewing the literature, the present study aims to describe a new technique for correcting the auricular axis and ear upper pole with a suture in the portion of the helical crus known as the Sundfeld-Reis technique. According to Adamson et al., this technique provides better positioning of the ear's upper pole in relation to the temporal pole without the need for suturing the triangular fossa region in the periosteum of the temporal bone. Therefore, using the Sundfeld-Reis technique, the pinna is placed parallel to the nasal dorsum, providing a natural result after otoplasty. The proposed technique is the latest possibility in the world of otoplasty that attains more natural results with fewer surgical interventions.

Dentre as diferentes anomalias que acometem as regiões de cabeça e pescôço, as orelhas em abano se encontram entre as mais frequentes, apresentando desproporcionalidade conchal e/ou falta de curvatura da antélice. Existe na literatura um grande espectro de técnicas para a correção dessas deformidades, citando-se como as mais consagradas as técnicas de Pitanguy, Converse, Stenvers, Stenstroem, Mustardé, Furnas e Horlock. Todas essas técnicas buscam restaurar a harmonia da face com proporcional dimensionamento do pavilhão auricular, ângulo aurículo-cefálico adequado e curvatura de antélice natural. Após revisão da literatura, o presente estudo pretende descrever uma nova técnica para correção do eixo auricular e o polo superior da orelha com uma sutura na porção do ramo da hélice, descrita como técnica de Sundfeld-Reis. Tal técnica proporciona melhor posicionamento do polo superior da orelha em relação ao temporal, sem a necessidade da sutura realizada na região da fossa triangular no periósteo do osso temporal, como orientado por Adamson et al. Outrossim, com o ponto de Sundfeld-Reis há posicionamento do pavilhão auricular paralelo ao dorso nasal, proporcionando um resultado natural da otoplastia. A proposta técnica se fulgura como mais uma possibilidade arregimentada no universo da otoplastia, vislumbrando resultados mais naturais, com menores intervenções cirúrgicas.

Título: Cochlear Implantation and Single-sided Deafness: A Systematic Review of the Literature
Fonte: Int. arch. otorhinolaryngol. (Impr.);20(1):69-75, Jan.-Mar. 2016. tab.
Idioma: en.
Resumo: Introduction Current data show that binaural hearing is superior to unilateral hearing, specifically in the understanding of speech in noisy environments. Furthermore, unilateral hearing reduce oné s ability to localize sound. Objectives This study provides a systematic review of recent studies to evaluate the outcomes of cochlear implantation in patients with single-sided deafness (SSD) with regards to speech discrimination, sound localization and tinnitus suppression. Data Synthesis We performed a search in the PubMed, Cochrane Library and Lilacs databases to assess studies related to cochlear implantation in patients with unilateral deafness. After critical appraisal, eleven studies were selected for data extraction and analysis of demographic, study design and outcome data. Conclusion Although some studies have shown encouraging results on cochlear implantation and SSD, all fail to provide a high level of evidence. Larger studies are necessary to define the tangible benefits of cochlear implantation in patients with SSD.
