OBJECTIVES: To analyze outcome after otosclerosis surgery with stamedeotomy with blood clot sealing. PATIENTS AND METHODS: Otosclerosis surgery was performed in 150 adult patients between 1997 and 1999 by five surgical teams (70% of the procedures were performed by senior surgeons) and followed for 18 months. Stapedotomy was carried out under general anesthesia with an intrameatal approach in 96% of the cases. Stapedotomy (n=120, 80%) was performed with a drill in 141 cases and by laser in 9 (6%). Ninety percent of the Teflon prostheses had a 0.4 mm diameter and a 4.5 mm length. The footplate opening was sealed with blood clots. Venous interposition (n=30, 20%) was performed in the event of partial or total stapedectomy which occurred in spite of an initial stapedotomy attempt. RESULTS: The preoperative air-bone gap (ABG) was 32 +/- 10.3 dB. The gain in air conduction was 25 +/- 11.7 dB with 75% of the patients having more than 15 dB gain. The ABG was 10 +/- 5.4 dB with 73% of the patients having less than 5 dB gain. The interaural difference was 0.5 +/- 14.1 dB and the bone conduction (BC) variation was 1 +/- 7.5 dB. Functional failures were related to significant intralabyrinthine bleeding and revision procedure. The following factors had not effect on outcome: i) stapedotomy versus partial or total stapedectomy, footplate opening sealed by clots or vein, ii) diameter of the stapedotomy and/or the prosthesis, iii) surgical procedure performed by a junior surgeon. CONCLUSION: Sealing the stapedotomy opening with blood clots appears to provide reliable and reproducible functional outcome that remains stable over time. In this study, changing from partial to total stapedectomy with vein interposition did not modify the functional outcome.
