Abstract:
Semont maneuver was performed in 97 patients with benign paroxysmal positional vertigo involving the posterior semicircular canal.Among 97 patients the Semont maneuver was successful in 69 cases and failed in 28 cases.There were three nystagmus patterns during the third position of the Semont maneuver:orthotropic nystagmus (n=45), no nystagmus (n=42) and reversed nystagmus (n=10);and the effective rates in three groups were 93%, 64% and 0%, respectively (P<0.05).The duration of latency period and nystagmus status in Dix-Hallpike test has no effect on repositioning efficacy ( P>0.05) .
