摘要
Abstract
Objective To summarize clinical characteristics of patients suffering from large vestibular aqueduct syndrome (LVAS) and analyze possible reasons for misdiagnosis and missed diagnosis. Methods Nineteen cases of misdiag-nosed or unrecognized LVAS were included in this study. Clinical histories, pure tone audiometry, immittance audiometry, auditory brainstem response (ABR), and high resolution CT (HRCT) image of temporal bone were reviewed in each case. Results The mean age at diagnosis in the 19 patients was 8.34 ± 8.09 years, although the mean age of hearing loss onset was 1.69 ± 1.42 years. Among the 19 patients, 10 were misdiagnosed for sensorinearal deafness, 3 for mixed deafness, 2 for Meniere' s disease, and 4 were not diagnosed because hearing loss was ignored by their parents. Seven patients (14 ears) were older than 6 years and their mean hearing level was 84.5 ± 12.8 dB nHL on pure tone audiometry, Among them, air bone gap existed in low frequencies in 7 ears. Twelve patients (22 ears) were six 6 years old or younger, and their mean hearing level was 67.81 ± 18.53 dB nHL on ABR. In all 36 ears, mean width of the vestibular aqueduct was 3.96 ± 1.36 mm. The vestibular aqueduct communicated with the common cms in 32 ears and with the vestibule in 10 ears. Mondini's deformity was seen in 23 ears. Conclusion To avoid missed diagnosis of LVAS, HRCT should be adopted as a routine examination for children who have unaccountable fluctuant sensorineural or mixed hearing loss or equilibrium disorders关键词
