Acoustic parameters of snoring sound to assess the effectiveness of sleep nasendoscopy in predicting surgical outcome.

Objective: To assess the effectiveness of two grading systems used to predict surgical outcome in nonapneic snorers.

Study Design: A prospective observational study. Prior to undergoing palatal surgery, 20 patients completed a sleep nasendoscopic examination involving sequential steady-state sedation with intravenous propofol.

Acoustic parameters of snoring sound to assess the effectiveness of the Müller Manoeuvre in predicting surgical outcome.

Objective: To assess the effectiveness of the Müller Manoeuvre in predicting surgical outcome in non-apnoeic snorers.

Methods: Forty-one non-apnoeic snorers performed the Müller Manoeuvre, prior to palatal surgery for snoring. Pre-operatively and between 1.
