    Drug Induced Sleep Endoscopy (DISE) is a specialised procedure used to investigate obstructive sleep apnoea (OSA) or snoring. It involves examining your airway with a small flexible camera while you are in a state of light sleep, induced with medication. This allows us to see which parts of your airway collapse during sleep and what type of collapse is occurring, which is not possible when you’re awake.

    Understanding the pattern and level of airway collapse helps guide decisions about the most appropriate treatment, including surgery or other alternatives.

    I often perform DISE in conjunction with nasal surgery (such as septoplasty or turbinate reduction), particularly in patients who are not yet ready for multilevel airway surgery. It may also be used in children with persistent OSA following adenotonsillectomy to assess ongoing causes of airway obstruction including lingual tonsil hypertrophy and sleep dependent laryngomalacia.
