Abstract: Objective To analyze the objective hearing results of children with complaints of hearing or speech retardation in Xinjiang,in order to provide references for the development of children's hearing screening. Methods During January 2018 to December 2019,530 children with complaints of hearing or speech retardation were collected from Otolaryngology Department of People's Hospital of Xinjiang Uygur Autonomous Region. The objective hearing of children was evaluated by click evoked auditory brainstem response,tone-burst evoked auditory brainstem response,distortion product otoacoustic emissions and tympanometry. Results There were 161 children with normal hearing (30.38%) and 369 children with hearing loss (69.62%). Among them,35 cases (6.60%) had monaural hearing loss and 334 cases (63.02%) had binaural hearing loss,79.13% of them had severe or very severe hearing loss,and there was no statistically significant difference between the proportion of children with severe or very severe hearing loss among different ethnic groups (P>0.05). There were 318 cases of sensorineural hearing loss and 51 cases of conductive hearing loss. The mean age at diagnosis was (3.75±1.38) years old for 369 children with hearing loss,and the difference was statistically significant among Han,Uyghur,Kazakh and Hui(F=9.411,P<0.01),with Uyghur being significantly later than Han and Hui (P<0.01),and the Kazakhs being significantly later than the Uyghurs (P=0.007). But there was no statistically significant difference between Hui and Han (P＞0.05). Conclusions This region should establish a perfect network platform of hearing screening,diagnosis and treatment,and follow-up. At the same time,it is supposed to carry out children's hearing screening as soon as possible,so that more children with hearing loss can receive early detection,early diagnosis,and early intervention.
