Popis: | OBJECTIVE To prospectively evaluate the hearing results in surgically treated cases of stapes fixation in patients with osteogenesis imperfecta. STUDY DESIGN A prospective study of osteogenesis imperfecta patients with stapes fixation. SETTING One tertiary referral center. PATIENTS Eighteen patients (23 ears) who underwent stapes surgery from 1994 to 2004 were prospectively included. INTERVENTION Stapedotomy with vein graft interposition and reconstruction with a Teflon piston or a bucket handle (cup) prosthesis. MAIN OUTCOME MEASURES Preoperative and postoperative audiometric evaluation using conventional audiometry. Air-bone gap, bone-conduction thresholds, and air-conduction thresholds were measured. Postoperative audiometry was performed at 6, 9, 12, 18, and 24 months after surgery and at a yearly interval thereafter. RESULTS Overall, a postoperative air-bone gap closure to within 10 dB was achieved in 85.7% of cases. Postoperative improvement of air-conduction thresholds superior to 20 dB was found in 57% of cases. The postoperative bone-conduction thresholds were unchanged. CONCLUSION This study shows that safe and successful stapedotomy is possible in cases of stapes fixation in patients with osteogenesis imperfecta. |
