  • Title: Postural restrictions in labyrintholithiasis.
    Author: Marciano E, Marcelli V.
    Journal: Eur Arch Otorhinolaryngol; 2002 May; 259(5):262-5. PubMed ID: 12107530.
    Abstract:
    Benign paroxysmal positional vertigo (BPPV) is the most frequent labyrinthopathy in humans. Treatment consists mainly of liberatory maneuvers aiming to remove otolithic debris and subsequent postural restrictions in order to prevent debris from returning into the canal. The reappearance of symptoms after an effective liberatory maneuver was studied in a group subjected to restrictions and in a second group free from restrictions. The effects of these restrictions were evaluated. No statistically significant difference was found between the groups. Accordingly, restrictions seem to have no effect upon symptom recurrence. The slight supremacy of the Semont maneuver and the prevalence of subsequent relapse compared with the Epley maneuver suggests that these maneuvers could operate on different disorders (cupulolithiasis versus canalolithiasis). Finally, late recognition of relapse in patients who undergo restrictions might even make the liberatory maneuver less effective.
