The canalith repositioning maneuver (CRM), as defined by Epley, can be an effective treatment for benign paroxysmal positional vertigo (BPPV). The staff at Başkent University's Ear Nose and Throat Clinic performed CRM on 68 cases of canalithiasis in 64 BPPV patients from June 1996 to August 1997. Symptoms resolved after the first session in 49 patients (72%) and after the second session in 11 cases (16.2%). It was necessary to repeat the maneuver three times in two cases (2.9%) and four times in one patient (1.5%). Discounting three patients who were lost to follow-up, only two patients in our study did not respond to CRM treatment. There was no co-existing pathology found in all but two of the patients studied. Our experience indicates that unless there is no response to CRM or there is suspicion of an incorrect diagnosis, it is not necessary to perform diagnostic studies routinely for differentiating other neuro-otologic disorders prior to using CRM in BPPV patients diagnosed by the Dix-Hallpike test.
