Introduction: The coexistence among Menière Disease (MD) and the positional paroxysmal vertigo (PPV) has found but still doesn’t exist an evaluation of the frequency of the phenomenon.
Objective: In our study we detailed the coexistence PPV in patients with MD.
Methods: We observed consecutively and treated a group of 85 patients with MD, classified according to the American Academy of Otorhinolaryngology and Head and Neck Surgery (AAO-HNS) indications related to their clinical history and to the results of instrumental procedures. In all cases, during every visit we executed procedures for the search of paroxysmal positional nystagmus via infrared-ray video-oculography (VOGIR). We utilized a PPV classification which allows the distinction of recurrences in recurrent forms (PPV unilateral multi-episodic) when canalithiasis interests the same side of of the first episode and alternate (PPV bilateral not simultaneous) when contralateral side is involved.
Results: In 12 patients (14.1%) we diagnosed 1 or more episodes of canalithiasis, always involving the posterior semicircular canal. The success was obtained after the first liberatory maneuver in 10 patients (83.3%); a second treatment was necessary in 2 patients and was successful in one, while the other patient required a third treatment for his recovery. After a medium-period of 8.3 months without PPV we diagnosed a recurrence of canalithiasis in 6 of 12 patients (50%); canalithiasis was recurrent type in 5 patients, while was alternate type in 1 patient. In all cases liberatory maneuver was performed successfully after one treatment.
Conclusions: Our study confirms the coexistence of MD and PPV; and this one manifests itself always after MD.
