Abstract：
OBJECTIVE: To evaluate caloric response changes after endolymphatic sac decompression (ESD), together with hearing outcomes and the functional benefit of the operation.
METHODS: A retrospective chart review of subjects who underwent endolymphatic sac decompression at a tertiary referral centre was performed. Data on audiological results, caloric testing, and functional level scale of the patients were analysed.
RESULTS: Twenty-eight patients who met our criteria were eligible for enrolment in the study. The average follow-up after surgery was 25 months (range, 13-41). Postoperative pure-tone threshold averages and reduced vestibular response values (RVR) were not significantly altered by ESD; whereas, functional level scores improved significantly.
CONCLUSIONS: Endolymphatic sac decompression is a surgical procedure that preserves hearing and vestibular function, and improves the daily functional level of patients with Ménière\'s disease. ESD can be preferred both in bilateral and unilateral disease because it does not alter vestibular function and preserves hearing.

摘要：
目的：评估内淋巴囊减压（ESD）后的热量反应变化，以及听力结果和手术的功能优势。
方法：对在三级转诊中心接受内淋巴囊减压术的受试者进行回顾性图表回顾。听力学结果数据，热量测试,并对患者的功能水平量表进行分析。
结果：符合我们标准的28名患者符合纳入研究的条件。术后平均随访25个月(范围,13-41).术后纯音阈值平均值和前庭响应值（RVR）降低没有明显改变ESD;然而，功能水平得分明显提高。
结论：内淋巴囊减压术是一种保留听力和前庭功能的外科手术，并改善梅尼埃病患者的日常功能水平。ESD在双侧和单侧疾病中都是首选，因为它不会改变前庭功能并保留听力。
