Pediatric otosclerosis: Case report and literature review

SummaryOtospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus. Typically, otospongiosis presents as a slowly progressive conductive hearing loss in the third to fourth decade of life. Uncommonly children and adolescents may also have conductive or sensorineural hearing loss caused by otosclerosis. We describe a case of an 11-year-old patient, with progressive unilateral conductive hearing loss for 5 years. The otoscopic examination revealed a positive Schwartz's sign in the left ear. Audiometry, impedanciometry and CT scan showed characteristics that suggested otospongiosis. We reviewed clinical aspects, diagnosis and the therapeutic approach for otospongiosis in children

Otosclerose infantil: relato de caso e revisão da literatura Pediatric otosclerosis: case report and literature review

A otospongiose é uma osteodistrofia do osso temporal caracterizada pela reabsorção e neoformação óssea desordenada. Clinicamente, caracteriza-se por disacusia condutiva, neurossensorial, e/ou mista, progressiva e zumbidos. O início dos sintomas ocorre entre 30 e 40 anos de idade sendo rara sua manifestação na infância. Descrevemos o caso de um paciente de 11 anos de idade, com quadro de hipoacusia unilateral progressiva há 5 anos. O exame otorrinolaringológico revelou mancha rubra de Schwartze em orelha esquerda. A audiometria, imitanciometria e a tomografia computadorizada demonstraram características sugestivas de otospongiose. Realizamos uma revisão dos aspectos clínicos, diagnósticos e da conduta terapêutica da otospongiose na infância.<br>Otospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus.
