Association Between Chronic Rhinosinusitis and The Vestibular System

Objective: Objective: Chronic rhinosinusitis (CRS) is inflammation  of the nasal mucosa and paranasal sinuses.  Subjective complaint of dizziness can be observed in patients  with CRS. However, a review of the literature did  not reveal any prospective studies that have used videonystagmography  (VNG) to examine the vestibular system  of patients with CRS. The goal of this study is the evaluation  of the vestibular system of CRS patients. Methods: The study comprised 30 patients with CRS and  30 control subjects. The vestibular system was evaluated  through VNG. The association with vestibular function  was evaluated according to the Lund-Mackay score, the  Sino-Nasal Outcome Test-22 (SNOT-22) score, and the existence  of nasal polyps. Results: Abnormal caloric test results were observed in  eight (26.6%) of the 30 CRS patients. The caloric test results  were normal for the control group. The oculomotor  test results with VNG were normal for the CRS and control  groups. The abnormal caloric results were higher for  the CRS with nasal polyp patients than for the CRS without  nasal polyp patients. The VNG showed no correlation  among the SNOT-22 scores and the Lund-Mackay scores  in patients with CRS. Conclusion: Abnormal caloric responses can be observed  in patients with CRS with nasal polyps.
