ABSTRACT
Sensorineural hearing loss following middle ear surgery has been shown to occur in 1.2% to 4.5% of patients. Drill-generated noise as a cause of inner ear damage has been suggested, but documentation is lacking. In a prospective study of 30 patients,audiometric testing was done both preopeartive and postoperative period. The data were analyzed using the Student’s t test. No statistically significant difference was found. A sensorineural hearing loss soon after mastoidectomy is not due to the noise generated by the drill. In the event of any hearing loss during this period, other causes should be thought.
