Abstract
The purpose of this study was to compare the hearing results after total ossicular replacement with a titanium prosthesis or autologous incus in the absence of stapes suprastructure and presence of mobile footplate as a retrospective medical record review in a tertiary referral center setting. There were 49 patients who had total ossicular reconstruction (titanium prosthesis, 40 patients; autologous incus, 9 patients). Medical records were reviewed after total ossicular replacement. Air-bone gap at 1 and 2 years after surgery were determined with the 4-frequency average (0.5, 1, 2, and 4 kHz) and the American Academy of Otolaryngology-Head and Neck Surgery 4-frequency average (0.5, 1, 2, and 3 kHz). The number of patients who had air-bone gap < 20 dB was determined. For comparisons that were based on American Academy of Otolaryngology-Head and Neck Surgery 4-frequency average, mean air-bone gap at 2 years after surgery was significantly smaller for the titanium prosthesis (21 dB) than autologous incus group (31 dB; P a parts per thousand currency sign 0.03); the frequency of patients who had air-bone gap < 20 dB at 1 or 2 years after surgery was significantly greater for the titanium prosthesis (1 year, 40 %; 2 years, 56 %) than autologous incus group [1 year, 0 % (P a parts per thousand currency sign 0.03); 2 years, 0 % (P a parts per thousand currency sign 0.04)]. Titanium prosthesis ossiculoplasty gave better results than autologous incus in the absence of the stapes suprastructure and presence of a mobile footplate.
