Resumo: | Introduction: Otosclerosis is a common form of conductive hearing loss characterized by abnormal bone remodeling exclusively in the otic capsule. The prevalence of otosclerosis varies in racial populations and is described as being rare in black African populations. In this paper we aim to report five cases of clinical, and surgically confirmed, otosclerosis in black individuals, in São Tomé and Príncipe.Material and Methods: Since February 2011, Ear, Nose and Throat consultations and surgeries specialty have been carried out at Dr. Ayres de Menezes Hospital in cooperation with the project ‘Health for all’. A retrospective analysis was undertaken of the records of all patients subjected either to stapedectomy or partial stapedectomy until February 2014. Information regarding clinical presentation, audiometric data and surgery reports was recorded.Results: Five adult patients underwent stapedectomy or partial stapedectomy. All of them presented with normal otoscopy, conductive or mixed hearing loss on audiogram and normal tympanometry with absent stapedial reflexes. None of the patients had signs of infection or history of head trauma. Three cases showed improvement in the air-bone gap after surgery. The other two were lost to follow-up.Discussion: We documented and surgically confirmed five cases of clinical otosclerosis in this population. A thematic review was carried out and concluded that, despite being described as a rare event in this race, available literature on this topic is not enough to state that there is lower prevalence of otosclerosis amongst the African population.Conclusion: Even if not common, otosclerosis cannot be disregarded as a possible cause for conductive hearing loss among the population of São Tomé and Principe. |

Diferenças rácicas são evidentes na literatura e, ao contrário dos caucasianos, as descrições na população de origem africana são raras. Neste trabalho pretende-se reportar cinco casos observados, e cirurgicamente confirmados, de otosclerose em indivíduos de raça negra, em São Tomé e Príncipe.Material e Métodos: Desde fevereiro de 2011, efetuam-se consultas e cirurgias de Otorrinolaringologia no Hospital Ayres de Menezes, em São Tomé e Príncipe, inseridas no projeto ‘Saúde para todos – Especialidades’. Neste trabalho realizou-se um estudo retrospetivo dos doentes submetidos a estapedotomia ou estapedectomia parcial durante estas missões até fevereiro de 2014. Recolheu-se informação relativa à apresentação clínica, resultados audiométricos e relatórios cirúrgicos.Resultados: Cinco doentes, adultos, foram submetidos a procedimento cirúrgico. Todos apresentavam otoscopia normal, ausência de história de traumatismo cranioencefálico ou quadro infecioso, audiograma com hipoacusia mista ou de condução e timpanograma tipo A, sem reflexos estapédicos. Em três doentes foi possível realizar audiograma pós-operatório, verificando-se melhoria do gap aero-ósseo.Discussão: Neste trabalho documentam-se cinco casos de otosclerose clínica, e cirurgicamente confirmada, na população negra de São Tomé e Príncipe. Efetuada uma revisão temática, constata-se que, apesar de a otosclerose ser considerada rara nesta raça, os dados disponíveis parecem insuficientes para determinar se, de facto, diferentes raças têm diferentes incidências da doença.Conclusão: Apesar de rara, a otosclerose não pode ser ignorada como uma possível causa de hipoacusia de condução em São Tomé e Príncipe.Ordem dos Médicos2017-10-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfapplication/pdfimage/jpegimage/jpegimage/jpegapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568oai:ojs.www.actamedicaportuguesa.com:article/8568Acta Médica Portuguesa; Vol. 30 No. 10 (2017): October; 713-718Acta Médica Portuguesa; Vol. 30 N.º 10 (2017): Outubro; 713-7181646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/5204https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/6031https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/8991https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/9256https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/9257https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/9258https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/9259https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8568/9379Direitos de Autor (c) 2017 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessCampelo, PaulaCaroça, CristinaTinoco, CatarinaOliveira e Carmo, DiogoPaço, João2022-12-20T11:05:33Zoai:ojs.www.actamedicaportuguesa.com:article/8568Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:19:36.652783Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
