The value of sedation nasendoscopy: a comparison between snoring and non-snoring patients.
Sedation or sleep nasendoscopy is a widely-used investigation in snorers presenting to otolaryngologists in the UK, despite its non-physiological basis. The presence or absence of snoring and its site of generation were compared between a group of 205 snorers and another of 126 non-snorers. Snoring was produced at nasendoscopy in 45.3% of non-snorers but could not be produced in 18.1% of snorers. There was no significant difference in the site of sound production between the two groups and although the noise produced by the non-snoring group was quieter, this difference was not significant.
