A 40-year-old patient with otosclerosis undergoes stapedotomy. The surgeon decides to use a CO2 laser for the procedure. The primary advantage of using laser stapedotomy over conventional manual technique is:
- A Reduced risk of perilymphatic gusher
- B Precision of footplate fenestration with minimal mechanical trauma ✓
- C Avoidance of prosthesis displacement
- D Prevention of post-operative granulation tissue
Correct answer: B. Precision of footplate fenestration with minimal mechanical trauma
Explanation
Laser stapedotomy allows precise vaporization of the footplate with minimal mechanical vibration transmitted to the inner ear, reducing the risk of sensorineural hearing loss. The heat generated creates a bloodless field and controlled fenestration. While granulation may be reduced, this is not the primary advantage. Prosthesis displacement is a surgical technique issue unrelated to laser use.
