Abstract
Patients with nasal obstruction often have associated snoring. This study aims to find out if there are reliable predictors for the success or failure of septal surgery in relieving snoring in patients with symptomatic nasal obstruction secondary to a deviated nasal septum and who have associated snoring. Thirty patients were studied pre-operatively and at 4–12 months (mean 6 months) post-operatively. The intensity of snoring was measured on a visual analogue scale. Nasal patency was measured with a peak nasal inspiratory flow meter. The collapsibility of the soft palate was gauged by the degree of velopharyngeal closure on the Muller manoeuvre. Fifteen patients (50%) achieved snoring relief after septal surgery. The severity of nasal obstruction and intensity of snoring pre-operatively, the magnitude of nasal obstruction relief post-operatively and the degree of collapsibility of the soft palate were found not to influence the outcome of septal surgery on snoring. The relationship between nasal obstruction and snoring is complex and the alteration of airflow patterns after septal surgery is postulated to be important in influencing snoring relief.
