To evaluate the success rate of primary stapedotomy and to investigate the influence of prosthesis diameter on hearing outcome. Retrospective medical chart review of 125 cases who underwent primary small fenestra stapedotomy, from January 2001 to December 2018. The study population was divided in two groups based on Teflon prosthesis diameter - .6mm (60%, N=75) and .4mm (40%, N=5. Pre- and postoperative (≥12 months) air-conduction (AC), bone conduction (BC) and air-bone gap (ABG) thresholds were compared. Postoperative ABG≤10dB and
