改良Semont方法治疗后半规管良性阵发性位置性眩晕的短期疗效研究

目的　研究改良Semont方法治疗后半规管良性阵发性位置性眩晕（posterior semicircular canal benign paroxysmal positional vertigo，PSC-BPPV）的短期疗效。方法　2015年10月～2016年4月在耳鼻咽喉科门诊经Dix-Hallpike试验及Roll试验，确诊为单侧PSC-BPPV管结石症患者93例，应用改良Semont方法治疗，观察复位后3 d和7 d有效率。结果　治疗过程中部分患者出现不同程度眩晕、恶心症状，但所有患者均顺利完成复位治疗。93例应用改良Semont复位法复位，3 d随访，痊愈、有效和无效分别为72、16和5例，治愈率77.4%，总有效率94.6%；1周随访，痊愈、有效和无效分别为84、5和4例，治愈率90.3%，总有效率95.7%。结论　改良Semont复位法治疗PSC-BPPV可靠有效，可以作为治疗PSC-BPPV的有效补充。

Short term outcome of modified Semont maneuver for posterior semicircular canal benign paroxysmal positional vertigo

OBJECTIVE To study the short term outcome of modified Semont maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV).METHODS A total of 93 patients with PSC-BPPV were diagnosed using the methods of Dix-Hallpike test and Roll test from Oct. 2015 to April 2016. All the patients were treated with the modified Semont maneuver. The 3 and 7 day outcome were recorded. RESULTS During the treatment, some patients had different degrees of vertigo and nausea, but all the patients completed the treatment successfully. The number of cured, improved and ineffective patients were 72, 16 and 5 respectively with a cure rate of 77.4% and total effective rate of 94.6% at 3 days follow up, and 84, 5 and 4 respectively with a cure rate of 90.3% and total effective rate of 95.7% at 7 days follow up.CONCLUSION Modified Semont maneuver is an effective method for management of posterior semicircular canal BPPV.
