Sudden sensorineural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding, which was difficult to diagnose before the advent of magnetic resonance imaging. The purpose of this paper is to report a case of sudden hearing loss caused by a labyrinthine hemorrhage, and to present a review of the literature on this topic.
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. 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.

INTRODUÇÃO: A Síndrome de Morquio é uma mucopolissacaridose tipo IV, geralmente associada a perda auditiva. OBJETIVO: Investigar a presença de deficiência auditiva em paciente com a Síndrome de Morquio. MATERIAL E MÉTODO: Analisamos um paciente do sexo masculino, 16 anos, sindrômico, com alterações esqueléticas e extra-esqueléticas desde os dois anos de idade. Pais consangüíneos e quadro semelhante na família. Paciente apresentava queixa de hipoacusia progressiva há cerca de cinco anos. RESULTADOS: Paciente com estatura = 99 cm, peso = 27 kg, pescoço curto, aumento do diâmetro ântero-posterior, abdome globoso, geno valgo e hiperextensão de punhos. A otoscopia evidenciou opacificação bilateral das membranas timpânicas e o exame audiométrico demonstrou disacusia condutiva, de leve intensidade. DISCUSSÃO: As mucopolissacaridoses (MPS) são doenças causadas pela deficiência de enzimas lisossomais, resultando em acúmulo de mucopolissacarídeos em diversos tecidos corporais. A Síndrome de Morquio é uma MPS do tipo IV, transmitida por herança autossômica recessiva. Os depósitos tissulares podem se localizar nas vísceras, ossos, córnea e ouvidos, desencadeando alterações estruturais e funcionais. CONCLUSÃO: A Síndrome de Morquio é uma doença do metabolismo dos carboidratos, manifestando-se a partir dos 18 a 24 meses de idade e apresentando um espectro de manifestações clínicas. Ao otorrinolaringologista cabe detectar precocemente perdas auditivas, a fim de minimizar as limitações da própria evolução da doença.
