Objective: Canalith repositioning procedure (CRP) provides rapid and long-lasting relief of symptoms in most patients with
benign paroxysmal positional vertigo. However, some patients express BPPV without nystagmus in Dix-Hallpike positioning or
in other word subjective vertigo. The purpose of this study was to evaluate the efficacy of CRP in management of those
particular type of patients.

Materials and Methods: CRP was performed in eight hundred and fifty patients, diagnosed as having BPPV (450 male, 400
female, mean age 56.4 years) of whom 697 (82%) were diagnosed as having posterior PSC BPPV, 140(16.4%) diagnosed as
having Subjective BPPV, 11 (1.3%) diagnosed as having LSC BPPV and 2 (0.23%) diagnosed as having ASC BPPV. Outcome
of CRP for patients complaining of BPPV with apparent nystagmus were compared to outcomes of the CRP for patients
complaining of BPPV without apparent nystagmus.

Results: There was a significant improvement in patients complaining of BPPV without apparent nystagmus when treated by
CRP. The results were comparable to the outcome when using CRP in patients complaining of BPPV with apparent nystagmus

Conclusion: Even without having detected the pathognomonic nystagmus in patients complaining of BPPV, one can obtain
acceptable results in treatment of supposed canalithiasis. And the use of CRP maneuvers can provide a relief of vertigo.
