Abstract:
Objective To examine the causes of high frequency sensorineural hearing loss caused by piston technique of stapes surgery.Methods The retrospective analysis involved in thirty cases(49 ears)with stapedectomy from February 2004 to 2009 at our hospital.Pure tone audiometry was performed for each patient who underwent stapedectomy both during the two days preoperation and 1,3,6 months postoperation.Results One month after operation at 8000 Hz,the air conduction hearing threshold was 8 dB less than that before,4 000 Hz average bone conduction hearing threshold was 10 dB less than that before(P < 0.01).The average high-frequency hearingthreshold of ≥40 years old group was noticeably declined than that of 40 years old group(P < 0.01).There was no association between the tinnitus and high frequency hearing loss.(P >0.05).Conclusion Transient high-frequency sensorineural hearing losses occurred to most patients under going stapedectomy,but showed significant improvement,3 months after the surgery.The average high-frequency hearing threshold of ≥40 years old group was seriously declined than that of 40 years old group.
