The present findings suggest that complete control of vertigo after endolymphatic sac decompression surgery (ESDS) does not always depend on improved vestibular function or reduced endolymphatic hydrops. Vertigo control is, however, associated with hearing stability.
Among surgical treatments for intractable Meniere's disease, ESDS is performed to preserve and improve inner ear function. We examined the correlation between changes in vertigo frequency and neuro-otologic function to understand the condition of the inner ear in patients whose vertigo was completely controlled after undergoing ESDS.
This was a retrospective cross-tabulation study. Between 1997 and 2001, we treated 52 patients with intractable vertigo using ESDS and followed the patients regularly for 2 years. Postoperatively we evaluated and recorded changes in vertigo attack frequency, maximum slow phase eye velocity, worst hearing level, and glycerol test results according to modified American Academy of Otolaryngology-Head and Neck Surgery 1995 criteria.
We found no correlation between vertigo control and vestibular function. There was also no correlation between vertigo control and negative conversion of the glycerol test. There was a significant correlation between vertigo control and hearing control .
目前的研究结果表明，内淋巴囊减压手术（ESDS）后眩晕的完全控制并不总是取决于前庭功能的改善或内淋巴积水的减轻。然而，眩晕的控制与听力稳定性相关。
在难治性梅尼埃病的手术治疗中，ESDS旨在保留和改善内耳功能。我们研究了眩晕频率变化与神经耳科功能之间的相关性，以了解接受ESDS后眩晕得到完全控制的患者的内耳状况。
这是一项回顾性交叉列表研究。1997年至2001年间，我们使用ESDS治疗了52例难治性眩晕患者，并对患者进行了为期2年的定期随访。术后，我们根据1995年美国耳鼻咽喉-头颈外科学会修订标准，评估并记录眩晕发作频率、最大慢相眼速度、最差听力水平和甘油试验结果的变化。
我们发现眩晕控制与前庭功能之间无相关性。眩晕控制与甘油试验转阴之间也无相关性。眩晕控制与听力控制之间存在显著相关性。
