LANDMARK: Sleep nasal endoscopy to assess level of obstruction in OSA

Sleep nasendoscopy: a technique of assessment in snoring and obstructive sleep apnea.

Croft CB, Pringle M. Sleep nasendoscopy: a technique of assessment in snoring and obstructive sleep apnoea. Clin Otolaryngol Allied Sci. 1991;16(5):504-9.

Take Home Points:

• Sleep nasal endoscopy is a method to assess a patient’s level of obstruction in a sleeping state
• This test can help determine single level versus multilevel obstruction in patients with obstructive sleep apnea, and therefore, the ideal surgical intervention.
• Those with multilevel obstruction are less likely to benefit from uvulopalatopharyngoplasty (UPPP).
