Abstract

To assess and compare the functional results obtained by means of multiple-shot Erbium: yttrium-aluminum-garnet (Er:YAG) laser to those obtained using "one-shot" CO(2) laser stapedotomy in patients affected by otosclerosis. A retrospective case review was performed. Of the total number of 123 patients (114 ears) who underwent primary small-fenestra stapedotomy from January 2006 to September 2008, seven patients who received multiple-shot laser CO(2) stapedotomy were excluded from the study. The remaining 116 patients (104 ears) were sorted, and "one-shot" CO(2) laser stapedotomy (group A) was performed in 35/104 and Er:YAG laser stapedotomy (group B) in 69/104. After surgery, air conduction-pure tone average (AC-PTA) and air-bone gap (ABG) improved significantly in both groups, whereas sensorineural hearing loss (SNHL) and bone conduction (BC)-PTA did not change in both the groups. In group A, the postoperative ABG was significantly better (12.63 vs. 14.86 dB). Moreover, after "one-shot" stapedotomy, the AC-PTA significantly improved in all tested frequencies. On the contrary, in group B the AC-PTA improved significantly only in two frequencies (0.5 and 1 kHz). Consistent with previous reports, our findings confirm that laser stapedotomy is a safe and effective surgery, regardless of the technique. Based on our functional results, the "one-shot" CO(2) laser technique seems to be associated with a significantly better postoperative ABG if compared to Er:YAG laser stapedotomy.
