[Otosclerosis surgery with CO2 laser].

Since Shea described the stapedectorny, many physicians have developed modifications of the technique, prosthesis or instrumentation. We have adopted one of the most recent advances to the treatment of otosclerosis, CO2 laser. Interventions were carried out in 20 consecutive ears using CO2 laser. Otosclerosis with type I, II and III foci were diagnosed and stapedectomies were reviewed. Stapedectomy was performed with a Causse prosthesis. We describe the technique and the laser power and application time used. The preoperative and auditory results at 1 month are reported. The advantages of opening otosclerosis with CO2 laser as the first or review procedure are analyzed.
