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.
