Frequency-specific hearing assessment after canal wall-down tympanoplasty for chronic ear diseases
摘要
Abstract
Objectives To analyze frequency-specific hearing results after canal wall-down tympanoplasty for chronic ear diseases, in relation to various surgical factors. Methods Patients who underwent canal wall-down tympanoplasty for chronic ear diseases from June 2008 to January 2011 in the Department of Otolaryngology, Eye Ear Nose & Throat Hospital, Fudan University were reviewed retrospectively (n=87). Using pure tone audiometry, air-conductive threshold (AC), bone-conductive threshold (BC) ,and air-bone gap (ABG), and pre- and post-operative changes were analyzed for each of the following frequencies: 0.25 kHz, 0.5 kHz, 1 kHz, 2 kHz, 3 kHz, 4 kHz (AC and BC) and 6 kHz (AC). Frequency-specific results were investigated in relation to various surgical factors. Results Both AC and ABC results showed improvements at each frequency, primarily in the low and mid frequencies. The improvement decreased gradually from low to high frequencies. BC results showed significant improvement at every frequency except 4 kHz. In patients without ossiculoplasty, BC results improved significantly only at 1 kHz. Conclusion Canal wall-down tympanoplasty for chronic ear diseases can improve hearing primarily in low and mid frequencies.关键词
