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%).
