- Abstract
The objective was to assess audiological results after total ossicular reconstruction for stapes fixation. The study is a retrospective evaluation conducted in a tertiary referral centre. The patients were 16 adults with conductive or mixed hearing loss and stapes fixation due to tympanosclerosis or otosclerosis. A total or partial stapedectomy with perichondrium interposition on the oval window and ossicular reconstruction with titanium total prosthesis were done. To assess pre- and post-operative (1 and 4 years) air and bone-conduction thresholds (frequencies 0.5, 1, 2, 3 kHz), pure-tone average air and bone conduction, and air-bone gaps were measured and the number of decibels of closure of the air-bone gap at 1 year and at 4 years were compared. One year after surgery, air conduction thresholds and pure-tone average air conduction were improved for all frequencies, and there were no significant differences in bone conduction thresholds or in pure-tone average bone conduction. There were no differences in air and bone conduction thresholds, pure-tone average air or bone conduction between 1 and 4 years. The air-bone gap was significantly reduced 1 year after surgery and remained so at 4 years. (Preoperative air-bone gap, 34.04 dB; at 1 year, 16.40 dB; at 4 years, 17.3 dB. Decibels of closure of the air-bone gap at 1 year, 17.64 dB; at 4 years, 16.74 dB.) No differences were found between otosclerosis subjects and all other cases combined. Total ossicular reconstruction in stapes fixation due to tympanosclerosis or otosclerosis produces satisfactory short- and long-term auditory results.
