    Abstract:
    OBJECTIVE: To analyze the constitute, imaging and auditory characteristics of pediatric patients with congenital malformations of inner ear in sensorineural hearing loss(SNHL). METHOD: Imaging and auditory data of 125 cases (225 ears) in 860 pediatric patients with congenital SNHL who referred to ENT department of Shanghai Children Medical Center from February 2005 to January 2010 were retrospectively studied. RESULT: Congenital malformations of inner ear accounted for 14.5% in 860 pediatric patients with congenital SNHL. Bilateral ear was involved in 98 cases (78.4%), unilateral in 27 cases (21.6%). One hundred and sixty-seven ears (74.2%) were identified as profound deafness, 36 ears (16%) severe deafness and 22 ears (9.8%) moderate deafness in 225 ears, respectively. In present group, large vestibular aqueduct (75.6%) was the most common and next was vestibular deformity (32%), then cochleovestibular deformity (23.1%). Mondini deformity (55.8%) was the most common and common cavity deformity (28.9%) next in cochleovestibular deformity. Profound deafness in cochlea involved congenital malformations of inner ear was significantly more than those in no cochlea involved malformations. CONCLUSION: The results are of importance for understanding the constitute of congenital malformations of inner ear in pediatric patients with congenital SNHL in China, for etiological diagnosis of congenital SNHL, for intervention including hearing aids or cochlear implant and prognosis.
