Therapeutic effects of small fenestra stapedotomy with semiconductor diode laser: a comparison with microdrill / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effects of small fenestra stapedotomy with semiconductor diode laser and microdrill in patients with otosclerosis.</p><p><b>METHODS</b>Twenty-six patients (29 ears) undergoing stapedotomy with semiconductor diode laser and 19 patients (21 ears) with microdrill were compared for the hearing results and complication rates.</p><p><b>RESULTS</b>No statistically significant differences were found in postoperative speech frequency and high frequency pure tone average in closing the air-bone gap between the two groups. The ears treated by stapedotomy with semiconductor diode laser showed significantly better preoperative minus the postoperative air-bone gap and milder dizziness.</p><p><b>CONCLUSION</b>In spite of the good hearing outcomes in both groups, small fenestra stapedotomy with semiconductor diodelaser can achieve better results and reduce the incidence of complications.</p>
