Abstract
- The aim of this study was to analyze and compare the results obtained in otosclerosis patient undergoing stapedotomy and partial stapedectomy.Retrospective review of surgical series. The guidelines of the American Academy of Otolaryngology-Head and Neck Surgery for the evaluation of results of treatment of conductive hearing loss were used.Pure tone average (0.5 to 3 kHz) air-bone gap was 6.1 dB in the partial stapedectomy and 6 dB in the stapedotomy group. The air-bone gap (ABG) closure rate did not differ between the 2 groups, except at 4 kHz, where stapedotomy group showed greater closure (P 0.003). Mean postoperative ABG gain was significantly (P0.05) higher in the stapedotomy group at 2, 3, and 4 kHz. Mean postoperative air-conduction gain did not differ significantly. Mean postoperative bone conduction (BC) change (1, 2, and 4 kHz) was 3.68 dB in partial stapedectomy and -0.02 dB in stapedotomy group, the difference being significant (P 0.007). Differences in BC change between the 2 groups were significant at each frequency.Similar good results can be obtained in experienced hands using either partial stapedectomy or stapedotomy technique. ABG closure rates were analogous in the 2 techniques as well as the complication rate. Although stapedotomy obtain better results at high frequencies, partial stapedectomy is associated with increased BC threshold at all frequencies.
