INTRODUCTION AND OBJECTIVE: Benign paroxysmal positional vertigo is one of the most common vestibular disorders, with a lifetime prevalence of 2.4%. This study aimed to assess age, gender, lesion type and site, association with other vestibular diseases, progression and recurrence in a Portuguese population.
METHODS: This was a retrospective observational study of 101 patients diagnosed with benign paroxysmal positional vertigo by the same senior doctor, in a tertiary academic hospital, between January 2009 and May 2011.
RESULTS: A total of 101 cases were pooled, with a mean age of 56.57±15.33 years (15-90 years). From these, 72.3% were women. The posterior canal was affected in 72.3%, the lateral in 24.7%, the anterior in 2% and multiple canals in 1%. Unilateral canal and left labyrinth involvement were more frequent. The therapeutic maneuver used most was Epley's. Recurrence was observed in 10.9% of the cases. It was idiopathic in 83.2% of cases. No association was found between the number of maneuvers necessary to treat benign paroxysmal positional vertigo and etiology.
CONCLUSION: Benign paroxysmal positional vertigo is more frequent in female subjects, in the 6th decade and involves preferably the posterior semicircular canal of the right labyrinth. In most cases it is idiopathic and treatment with repositioning maneuvers has a mean success of 90%. Our results were in accordance with the literature; nevertheless, in this study the left labyrinth was most affected and the follow-up period was variable.
