- ItemAcesso aberto (Open Access)Anatomia microscópica do canal carótico e suas relações com a cóclea e a cavidade timpânica(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2005-08-01) Penido, Norma de Oliveira [UNIFESP]; Borin, Andrei [UNIFESP]; Fukuda, Yotaka [UNIFESP]; Lion, Cristina Navarro Santos [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The knowledge of the relations between the noble and vital structures of temporal bone is still a great challenge for the otologic surgeon. The microscopic anatomic studies of the temporal bone are one of the greatest help to prevent lesions during surgical intervention. AIM: To study the anatomic correlations between the carotid canal and the cochlea, and the occurrence of dehiscence of the carotid canal in the middle ear tympanic cavity. MANTERIAL AND METHODS: Microscopic study of 122 human temporal bones. RESULTS: The average distance between the carotid canal and the cochlea were: the shortest distance, 1.05mm; basal turn, 2.04mm; middle turn, 2.32mm; and apical turn, 5.70mm. The occurrence of dehiscence of the carotid canal inside the tympanic cavity was 35.2%. CONCLUSION: The small distances between the cochlea and carotid canal, and the high incidence of dehiscence in the tympanic cavity remind us that anatomical knowledge of the temporal bone is required for the best qualification of otologists.
- ItemAcesso aberto (Open Access)Complicações intratemporais das otites médias(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2013-04-01) Maranhão, André Souza de Albuquerque [UNIFESP]; Andrade, José Santos Cruz de [UNIFESP]; Godofredo, Valéria Romero [UNIFESP]; Matos, Rafaella Caruso [UNIFESP]; Penido, Norma de Oliveira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Otitis media (OM) is considered a potentially severe disease due to the risk of complications. OBJECTIVE: To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. METHOD: This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. RESULTS: 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. CONCLUSION: The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.
- ItemAcesso aberto (Open Access)Estudo anatômico do osso temporal de um primata não-humano (Callithrix sp)(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2008-06-01) Borin, Andrei [UNIFESP]; Covolan, Luciene [UNIFESP]; Mello, Luiz Eugenio Araujo de Moraes [UNIFESP]; Okada, Daniel Mochida [UNIFESP]; Cruz, Oswaldo Laércio Mendonça [UNIFESP]; Testa, Jose Ricardo Gurgel [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade Federal São Paulo Departamento OtorrinolaringologiaThe search for experimental (animal) models is essential to the development of clinical studies. AIM: To demonstrate, by means of micro dissection techniques, the anatomical structures of temporal bones from the primate Callithrix sp. STUDY DESIGN: Experimental. METHODS: Dissection of temporal bone structures of Callithrix sp and photographic documentation. RESULTS: We identified the main constituents of the temporal bone (external, medium and inner ear and facial nerve). CONCLUSION: The non-human primate Callithrix sp. is an adequate experimental model for the studies of temporal bone structures given its close anatomical similarities to that found in humans.
- ItemAcesso aberto (Open Access)Estudo comparativo entre achados radiológicos e cirúrgicos na otite média crônica(Fundação Otorrinolaringologia, 2011-03-01) Prata, Anelise Abrahao Salge; Antunes, Marcos Luiz [UNIFESP]; Abreu, Carlos Eduardo Cesario De [UNIFESP]; Frazatto, Ricardo [UNIFESP]; Lima, Bruno Thieme [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); faculdade de medicina do ABC; Hospital Estadual de DiademaINTRODUCTION: The chronic otitis media (COM) is a prevalent disease and the most frequent cause of indication to mastoidectomy. Many studies have evaluated the use of tomography (CT) of temporal bones for preoperative evaluation of COM and its indication in the preoperative approach is still controversial nowadays. OBJECTIVE: To evaluate the sensitivity of the clinical and radiological findings of COM according to the intraoperative surgical results and histopathological findings. METHOD: Transversal retrospective study through collection of record data of patients with COM submitted to mastoidectomy in the period from 2007 through 2008 in our service. RESULTS: From a total of 82 ears, 40.24% had cholesteatoma. The CT presented 72.73% of sensitivity in the identification of cholesteatoma, 56.67% in the identification of changes to the ossicular chain and 100% in that of erosion of the lateral semicircular canal. CONCLUSION: The clinical and radiological findings showed a high level sensitivity with intraoperative findings as regards to the presence of cholesteatoma, large changes of the ossicular chain and erosion of the lateral semicircular canal. For minor changes to the ossicular chain, the facial nerve canal and the tympanic tegmen they described low sensitivity.
- ItemAcesso aberto (Open Access)Osteodistrofias do Osso Temporal: Revisão dos Conceitos Atuais, Manifestações Clínicas e Opções Terapêuticas(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2002-05-13) Cruz, Oswaldo Laércio Mendonça [UNIFESP]; Pessoto, Jurandy [UNIFESP]; Pezato, Rogério [UNIFESP]; Alvarenga, Eliézia Helena de Lima [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Osteodysplasia of the temporal bone included a significant amount of osseous diseases sharing bone matrix structural and composition damage. Otospongiosis is, by far, the most frequent form of this involvement in the temporal bone. Nevertheless, fibrous dysplasia and osteogenesis imperfecta are not rare and deserve attention. In this article, the authors present a discussion about the recent concepts of those less frequent forms of osteodysplasia of temporal bone, its options of treatment, illustrated with three clinical cases.
