Abstract
- BACKGROUND AND OBJECTIVES
The aim of this study is to analyze the causes of recurrent conductive hearing loss following stapedotomy, and then the final hearing results.
SUBJECTS AND METHOD
This study was a retrospective chart review of 6 patients who underwent revision stapedotomy for recurrent or persistent conductive hearing loss after primary stapedotomy. The intraoperative findings, surgical outcome including audiologic data and complications were noted.
RESULTS
Obstruction of oval window fenestration was demonstrated in 5 patients (83.3%), short prosthesis in 4 patients (66.7%), incus erosion in two patients (33.3%) and granulation around prosthesis and stapes in one patient. Successful hearing improvements, air-bone gap (ABG) reduced to 20 dB or less, were achieved in 5 ears (83.3%). There were no patients who noted sensorineural hearing loss and other significant complications after surgery.
CONCLUSION
More than 83% of revision stapedotomy cases have had successful closure of their ABG. The most common problem was obstruction of oval window fenestration (83.3%).
