ABSTRACT

Background: Benign paroxysmal postural vertigo is the most frequent form of peripheral vertigo.
Objective: To demonstrate the association of tubarian pathologies with benign paroxysmal postural vertigo.
Patients and methods: Thirty patients were studied from the outpatient Unit of Otolaryngology S.C., with a descriptive, longitudinal and prospective design. The inclusion criteria and the independent variable were: Patients with neuro-otological diagnosis of benign paroxysmal postural vertigo and otosalpingitis. The dependent variable: Post-operative neurootological diagnosis to six months and the participant variables: Age, sex, diagnosis of diseases from nose and throat, surgical procedure, tympanogram curve of pre-operative, tympanogram curve of postoperative to six months and neuro-otological diagnosis post-surgery to six months. We used the change between pre-operative neurootological diagnosis and post-operative neuro-otological diagnosis to six months, showing that the study has significant χ² (1) = 37,298, p ‹ 0.001 and the change between the type of tympanogram curve of preoperative and postoperative measurements, which also was statistically significant χ² (2) = 72.74; P‹0.001.
Results: The most frequent pathology was: sinusitis etmoidal; the surgical procedure most often used was: ethmoidectomy. The permeability of the Eustachian tube is linked to the cure of benign paroxysmal vertigo in 77% of cases.
Conclusions: Obstruction of the Eustachian tube is a predisposing factor of benign paroxysmal postural vertigo.
