Stapedotomy in Otosclerosis: Laser versus Fenestration

Background: Otosclerosis is a localized hereditary disorder of bone metabolism of the otic capsule. The most classical manifestation is conductive hearing loss secondary to stapedial fixation. Our study compares a series of CO₂ Laser Stapedotomy (LS) with a series of Conventional Stapedotomy (CS) with respect to technical advantages, hearing results and complications.

Aims: To evaluate whether CO₂ laser fenestration in primary stapedotomy for otosclerosis is safer than conventional fenestration techniques. Prospective, interventional randomized study.

Material and Methods: 40 patients (32 females, 08 males) who underwent surgery for otosclerotic disease between January 2017 and January 2018 were studied in our institute. Statistical analysis used: Paired student t test.

Conclusion: CO₂ Laser is a safe and efficient one shot technique. LS is technically less difficult, produces an atraumatic, bloodless opening in the footplate of stapes without mechanical manipulation of the stapes and less inner ear damage. The air bone gap closure is better in laser group (32 ± 3.85).
