Description
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” CO2 laser stapedotomy in patients aVected 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 CO2 stapedotomy were excluded from the study. The remaining 116 patients (104 ears) were sorted, and “one-shot” CO2 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 signiWcantly 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 signiWcantly better (12.63 vs. 14.86 dB). Moreover, after “oneshot” stapedotomy, the AC-PTA signiWcantly improved in all tested frequencies. On the contrary, in group B the ACPTA improved signiWcantly only in two frequencies (0.5 and 1 kHz). Consistent with previous reports, our Wndings conWrm that laser stapedotomy is a safe and eVective surgery, regardless of the technique. Based on our functional results, the “one-shot” CO2 laser technique seems to be associated with a signiWcantly better postoperative ABG if compared to Er:YAG laser stapedotomy.
