The efficacy of Gufoni maneuver for treating geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo

Abstract

Objective To investigate the efficacy of Gufoni maneuver for treating geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo (BPPV). Methods We retrospectively analyzed 87 patients diagnosed as geotropic nystagmus horizontal semicircular canal BPPV from January to December 2016. All patients were treated by Gufoni maneuver twice and examined on the next day to access the status of BPPV. Patients still with geotropic nystagmus or dizziness were treated by Gufoni maneuver twice again and examined after 30 min. The effect was assessed by "Diagnosis basis and curative effect appraisal of benign paroxysmal positional vertigo (2006, Guiyang)". Results The success rate of first treatment by Gufoni maneuver achieved to 71.26% (62/87) and increased to 86.21% (75/87) after the second treatment. Among these patients, 12 patients failed to recover, 8 of whom were treated by forced prolonged position (FPP) and recovered after one week, and 4 of whom turned to be posterior semicircular canal BPPV and were treated by Epley maneuver successfully. Conclusions Gufoni maneuver is proved to be a good treatment for geotropic nystagmus horizontal semicircular canal BPPV and the efficacy increases after repeated treatment.
