ABSTRACT

The youthful upper eyelid shows no depression because the orbital contents are firm and the eyelids are tightly stretched across the bony socket. With progressive aging, there is skeletonization of the orbit as the periorbital tissues undergo laxity or absorption. With aging, hollowing of the eyes results in a deep upper eyelid sulcus. Most surgical procedures that address the aging appearance of the eyes involve excision of excess skin and removal of fat, with resultant volume disproportion that may lead to further hollowing and older appearance. Few procedures have been introduced that address age-related periorbital volume disproportion. We discuss a newly developed surgical technique for the correction of this major orbital aesthetic problem. In this surgical technique, the orbital rim periosteum, periorbita, and released superior extraconal orbital fat are used to fill the superior periorbital space, improving the patient's appearance.

ABSTRACT

OBJECTIVE: The surgical removal of a jugular foramen (JF) tumor presents the neurosurgeon with a complex management problem that requires an understanding of the natural history, diagnosis, surgical approaches, and postoperative complications. Cerebrospinal fluid (CSF) leakage is one of the most common complications of this surgery. Different surgical approaches and management concepts to avoid this complication have been described, mainly in the ear, nose, and throat literature. The purpose of this study was to review the results of CSF leakage prevention in a series of 66 patients with JF tumors operated on by a multidisciplinary cranial base team using a new technique for cranial base reconstruction. METHODS: We retrospectively studied 66 patients who had JF tumors with intracranial extension and who underwent surgical treatment in our institutions from January 1987 to December 2001. Paragangliomas were the most frequent lesions, followed by schwannomas and meningiomas. All patients were operated on using the same multidisciplinary surgical approach (neurosurgeons and ear, nose, and throat surgeons). A surgical strategy for reconstruction of the cranial base using vascularized flaps was carried out. The closure of the surgical wound was performed in three layers. A specially developed myofascial flap (temporalis fascia, cervical fascia, and sternocleidomastoid muscle) associated to the inferior rotation of the posterior portion of the temporalis muscle was used to reconstruct the cranial base with vascularized flaps. RESULTS: In this series of 66 patients, postoperative CSF leakage developed in three cases. These patients presented with very large or recurrent tumors, and the postoperative CSF fistulae were surgically closed. The cosmetic result obtained with this reconstruction was classified as excellent or good in all patients. CONCLUSION: Our results compare favorably with those reported in the literature. The surgical strategy used for cranial base reconstruction presented in this article has several advantages over the current surgical techniques used in cases of JF tumors.

ABSTRACT

Frey's syndrome is a phenomenon of hemifacial flushing and sweating after gustatory stimulus, usually secondary to surgical trauma over the parotid gland, although other injury mechanisms may be seen. It is accepted as a result of aberrant regeneration of facial autonomic nerve fibers. Treatment evolved from ineffective medical and surgical approaches to botulinum toxin. We evaluate the effectiveness and safety of botulinum toxin in the treatment of this complication in two patients.

ABSTRACT

A síndrome de Cowden, com herança autossômica dominante, caracteriza-se pela presença de hamartomas. As manifestaçöes mais comuns desta síndrome säo pólipos gastrointestinais, afecçöes de tireóide (bócio ou neoplasia), afecçöes de mama (doença fibrocística ou neoplasia) e lesöes cutâneo-mucosas. O critério mais consistente para o diagnóstico säo as lesöes hamartomatosas de pele e /ou mucosas, cuja incidência é de 99-100 por cento. Os autores relatam o caso de um paciente do sexo feminino com 36 anos de idade, que apresentou lesöes papilomatosas de mucosa oral, adenoma folicular de tireóide e pólipo inflamatório em intestino grosso. Também destacam a importância das manifestaçöes cutâneo-mucosas para os otorrinolaringologistas visando ao diagnóstico e o adequado seguimento destes pacientes com relaçäo a neoplasias malignas principalmente de tireóide e de mama

ABSTRACT

Foram analisadas diferentes medidas relacionadas ao acesso nasal transesfenoidal em 18 hemicabeças de cadáveres com o objetivo de estudar os limites e vantagens dessa via. Foram obtidos os seguintes valores médios (mm) para as principais medidas: diâmetro maior da narina 15,18; altura da cavidade nasal 44,11; distância narina - sela turca 71,71. Esses valores demonstram ser o acesso nasal uma via ampla e direta à sela turca. O presente estudo demonstrou também ser possível nesse acesso preservar o septo cartilágino e outras estruturas que säo usualmente lesadas no acesso sublabial.

ABSTRACT

O comprometimento do seio cavernoso por lesoes, seja pela infiltraçao de tumores ou pela presença de patologias vasculares, sempre constituiu desafio ao neurocirurgiao, sendo, na maioria das vezes, o limite de um tratamento cirúrgico radical. O desenvolvimento de novas técnicas cirúrgicas para a base do crânio, associado a novos meios de diagnóstico por imagem, tem permitido abordagem mais segura e radical para muitas lesoes desta regiao. Neste trabalho, a experiência no tratamento de 88 pacientes com lesoes do seio cavernoso é apresentada. Esses pacientes foram atendidos entre janeiro de 1987 a junho de 1995. Meningeomas foram os tumores mais freqüentemente encontrados, seguidos dos adenomas invasivos da hipófise. Ressecçao total da lesao foi possível em todos os casos de neurinomas do trigêmeo, angiofibromas juvenis, condrossarcomas e hemangiomas cavernosos. Ressecçao radical de meningeomas invasivos e adenomas da hipófise nao foi possível em muitos casos, porém melhora dos sintomas pré-operatórios ocorreu na maioria dos pacientes. Lesoes vasculares como fístulas carótido- cavernosas e aneurismas da porçao intracavemosa da artéria carótida interna foram tratadas com técnicas endovasculares utilizando baloes e molas destacáveis.O conhecimento da anatomia cirúrgica desta regiao é fundamental para o sucesso da abordagem cirúrgica com preservaçao das estruturas vásculo-nervosas. Detalhes de dissecaçoes anatômicas realizadas no nosso serviço sao apresentados neste trabalho. A monitorizaçao intraoperatória dos nervos cranianos I, III e VI mostrou-se de utilidade na maioria dos casos em que o tumor apresentava tendência infiltrativa. A infiltraçao de nervos cranianos e da artéria carótida interna foi o fator limitante da ressecçao radical em alguns pacientes portadores de meningeomas. Com o aumento da experiência cirúrgica, nossa conduta no tratamento destes tumores tornou-se mais agressiva, com tentativa de remoçao radical na maioria dos pacientes. A preservaçao da funçao do nervo oculomotor é de fundamental importância. Neste trabalho, expomos nossos resultados e a conduta atual nos pacientes portadores de lesoes expansivas do seio cavernoso os quais apresentam funçao preservada do nervo oculomotor.

ABSTRACT

The development of new diagnostic tools, microsurgical techniques and a review of the current classifications used of glomus tumors of temporal bone, led the authors to propose a new way to calssify these lesions. This classification is based on two anatomical landmarks: the temporal bone and the dura mater. These anatomical structures delineate three levels, where the tumors can be located: level E (ear), level N (neck), and level I (intradural). In this way, glomus tumors of temporal bone are grouped in four type E (ear), the tumor is limited to level E; type EN (ear and neck), the tumor is located in both levels E and N; type ENI (ear, neck and intradura), the tumor involves the three levels; and type M (miscellanea). Tumors type M are rare and comprise other possible combinations or isolated types (N, NI, EI and I). CLASSIFICATION CURITIBA 88 has the advantage of being simple and practical, indicating before surgery the composition of the surgical team (neurosurgeon, ENT surgeon, and head and neck surgeon)

ABSTRACT

O presente estudo proporciona uma informaçäo atualizada da bacteriologia aeróbica e anaeróbica da pele do conduto auditivo normal, e da secreçäo da otite média crônica simples e colesteatomatosa. Nas complicaçöes foi correlacionada a(s) bacteria(s) do foco com a(s) bactéria(s) do local de complicaçäo e testada a sensibilidade das bactérias aeróbicas a anaeróbias para vários grupos de medicamentos. Para os aeróbios foram testados: ampicilina, cloranfenicol, tetraciclina, trimetoprim-sulfametoxazol, cefoxitina, cefalotina, cefaridina, cefalexina, cefotaxima, amicacina, gentamicina, tobramina e netilmicina. Para anaeróbios: penicilina, eritromicina, tetramiciclina, clindamicina, cloranfenicol e metronidazol. A correlaçäo bacteriológica entre o foco e o local da complicaçäo permitiu sugerir o esquema terapêutico apresentado no texto
