[Long-term results of small fenestra stapedectomy compared with large fenestra technique].
OBJECTIVE
To evaluate the postoperative long-term hearing results of small fenestra stapedectomy versus large fenestra techniques.


METHODS
A retrospective review of 102 ears of 94 patients who had stapedectomy (small fenestra technique) performed by the same surgeon between 1972-1990 was conducted. Patients undergoing stapedectomy and stapedotomy were followed for 6.4 +/- 2.2 and 6.6 +/- 3.0 month in initial postoperative and 14.5 +/- 3.0 and 7.4 +/- 2.2 years in late postoperative, respectively.


RESULTS
There were no statistically significant differences in initial or late postoperative pure-tone (PTA), PTA air-bone gap, speech reception threshold (SRT) between the two groups. Ears treated by stapedotomy showed statistically better initial postoperative air-conduction threshold and initial 4-KHz air-bone gap closure, but the gap difference was not significant with late follow-up. The successful outcomes in both groups were stable over long-term follow-up. Results were the same when comparing the two procedures in the patients having undergone both.


CONCLUSIONS
These results show that, in the operation of an experienced surgeon for otosclerosis, either large or small fenestra technique provides satisfactory and stable long-term results.
