Effects of Varying Laser Parameters During Laser Stapedotomy on Intracochlear Pressures.

ABSTRACT:

Objective

Sensorineural hearing loss is a known complication of stapes surgery. We previously showed that laser stapedotomy can result in intracochlear pressures that are comparable to high sound pressure levels. Optimizing laser settings to those that correspond with the lowest pressure changes may mitigate risk for postoperative hearing loss. Here we quantify the effects of various laser parameters on intracochlear pressures and test the hypothesis that intracochlear pressure changes are proportional to the laser energy delivered.

Study design

Basic and translational science.

Setting

Cadaveric dissection and basic science laboratory.

Methods

Cadaveric human heads underwent mastoidectomies. Intracochlear pressures were measured via fiber-optic pressure probes
