Abstract
Objective:To determine whether the preoperative results of glycerol test of electrocochleography and hearing stage have a prognostic value on the effects of endolymphatic sac decompression surgery in patients with unilateral Meniere's disease. Method:A retrospective study was conducted of 58 unilateral Meniere's disease patients who underwent endolymphatic sac decompression surgery. The correlation between the preoperative results of glycerol test of electrocochleography， hearing stage and vertigo control was analyzed by Kendall test. Result:Patients in the positive glycerol test of electrocochleography group had better vertigo control after the decompression of the lymphatic sac than the negative group(P=0.029). Preoperative hearing staging was significantly associated with vertigo control after endolymphatic sac decompression(P=0.028). The better the preoperative hearing, the higher the control rate of vertigo after endolymphatic sac decompression. The stage Ⅰ patients were 91.7%, the stage Ⅱ patients were 78.1%, and the third stage Ⅲ patients were 57.1%, respectively. Conclusion:Our findings suggested that the positive preoperative results of glycerol test of electrocochleography and better hearing stage may indicate a better effects of endolymphatic sac decompression surgery in patients with unilateral Meniere's disease.
