Characteristics of Pure Tone Audiometry in Patients with Congenital Outer and Middle Ear Malformation
摘要
Abstract
Objective To report characteristics of pure tone audiometry in patients with congenital outer and mid-dle ear malformation.Methods Characteristics of pure tone hearing tests in 213 cases(253 ears) of congenital outer and middle ear malformations were retrospectively reviewed.Results On pure tone testing,198 ears(78.26%) showed con-ductive deafness,53 ears(20.95%) showed mixed deafness,and only 2 ears(0.78%) showed sensorineural deafness. Ex-cluding frequencies at which no response could be induced, among 206 cases (246 ears), the average air conduction threshold indicated moderate-severe (56-70 dB HL) (51.63%, 127/246) or severe (71-90 dB HL) (33.74%, 83/246) deafness in most ears. Of ears with conductive deafness, 59.60% (118/198) showed moderate-severe loss and 26.77% (53/198) showed severe loss, whereas 18.75% (9/48) of ears with mixed deafness showed moderate-severe loss and 62.50% (30/48) showed severe loss.Among ears showing 56-80 dB HL hearing loss, 82.83% (164/198) demonstrated conductive deafness and 58.33%(28/48) demonstrated mixed deafness.Bone conduction hearing loss happened mainly at 2 kHz(72.92%) at a mean threshold of 30.42±7.84 dB HL(10-60 dB HL).Conclusions Patients with congenital outer and middle ear malformation show mainly moderate-severe or severe conductive deafness,with slight bone conduction hearing loss happening mainly at 2 kHz.关键词
