Аннотация
OBJECTIVE: The purpose of this study was to present early and late bone-conduction hearing thresholds and data about cochlear and vestibular disturbances in patients after erbium:yttrium-aluminum-garnet (Er:YAG) laser stapedotomy in otosclerosis.
STUDY DESIGN: The study design was a retrospective study.
SETTING: The study was conducted at an academic tertiary referral center.
PATIENTS: In this study, audiologic data of 117 patients undergoing Er:YAG laser-assisted stapedotomy for otosclerosis between 1993 and 1999 were included.
MAIN OUTCOME MEASURES: The preoperative minus 2 postoperative (early, 1-3 days; late, at least 6 weeks) average pure-tone bone-conduction thresholds at 1, 2, and 4 kHz and 0.5, 1, 2, and 3 kHz were calculated. The postoperative appearance of nystagmus, vertigo, and tinnitus was analyzed.
RESULTS: A total of 91 of 117 patients showed unchanged preoperative minus postoperative pure-tone bone-conduction averages at 1, 2, and 4 kHz in the late postoperative measurement. A slight deterioration was observed in 8 of 117 patients. Regarding the frequencies 0.5, 1, 2, and 3 kHz, 97 of 117 patients showed unchanged preoperative minus postoperative pure-tone bone-conduction averages. A new transient tinnitus appeared in 37 of 117 patients, and a new persistent tinnitus was found in 3 of 117 patients. Most of the patients had no postoperative dizziness (63/117 patients) and no postoperative nystagmus (109/117 patients).
CONCLUSION: The study did not show significant sensorineural hearing loss at or below 3 kHz. Vestibular and cochlear function has no clinically relevant suppression after Er:YAG laser stapedotomy.
