Performance of older adult cochlear implant users in Hong Kong.

Objective: To compare the speech perception performance of older adults with that of adult cochlear implant (CI) recipients in a single center in Hong Kong.

Design: A retrospective study of 14 older adult CI users (age at operation, 56 to 77 yr old) and 14 adults (age at operation, 18 to 53 yr old) who received CIs and were matched for duration of profound deafness. The outcome indicator of their performance includes ratings of 0 to 7 on the speech perception category (SPC), which is based on their speech perception test scores at 6, 12, and 24 mo after implantation.

Risk factors for otitis media with effusion in Chinese schoolchildren: a nested case-control study and review of the literature.

Objective: To identify the risk factors for otitis media with effusion (OME) in Chinese schoolchildren and analyse the results with reference to the review of the literature.

Methods: The study subjects were 6-7-year-old children drawn from a school-screening program for OME in Hong Kong. Both positive and negative screens attended a hospital clinic for further assessment with repeated otoscopic examination and tympanometry as well as pure tone audiometry within 3 weeks after the initial school-screening.

[Comparison of prevalence rates of secretory otitis media in Hong Kong Chinese children with western populations].

Methods: From 1995 to 1998, primary schools, kindergartens and nurseries were selected by stratified randomization in Hong Kong of China. Six thousand eight hundred and seventy-two children of age 2 to 7 were examined on-site in the school premises by the otolaryngologist and audiologist with otoscope and tympanometry respectively.
