[Otosclerosis surgery with CO2 laser].

Area of Science:

• Otolaryngology
• Surgical Innovation
• Audiology

Context:

• Otosclerosis, a common cause of conductive hearing loss, often requires surgical intervention.
• Stapedectomy techniques have evolved, with recent advancements focusing on minimally invasive tools.
• The CO2 laser represents a modern approach to otosclerosis treatment.

Purpose:

• To evaluate the efficacy and outcomes of using the CO2 laser for stapedectomy in patients with otosclerosis.
• To describe the specific technique, laser parameters, and prosthesis used in CO2 laser stapedectomies.
• To analyze the advantages of employing the CO2 laser in primary or revision stapedectomy procedures.

Summary:

• Twenty consecutive ears diagnosed with otosclerosis (Types I, II, and III foci) underwent stapedectomy using a CO2 laser and Causse prosthesis.
• The study details the surgical technique, including laser power and application time.
• Preoperative and one-month postoperative auditory results are reported and analyzed.

Impact:

• The CO2 laser facilitates precise otic capsule dissection, potentially improving surgical outcomes in otosclerosis.
• This approach may offer advantages for both initial stapedectomy and revision surgeries.
• Findings contribute to the understanding of laser-assisted stapedectomy in managing hearing loss due to otosclerosis.
