Procedures: Sleep Endoscopy


Sleep Endoscopy, also known as Drug-Induced Sleep Endoscopy (DISE), is a diagnostic procedure used to evaluate the upper airway’s behavior during sleep. This technique offers invaluable insights for managing sleep-related breathing disorders like Obstructive Sleep Apnea (OSA). At Norelle Health’s Department of Sleep Medicine, we consider Sleep Endoscopy as a cornerstone in personalized treatment planning. This guide covers the what, why, and how of Sleep Endoscopy, including its relevance, benefits, and what to expect before, during, and after the procedure.

What is Sleep Endoscopy?

Sleep Endoscopy is a procedure where a flexible endoscope is inserted through the nose to observe the structure and function of the upper airway during a drug-induced sleep state. This procedure helps physicians identify the areas of obstruction, which is crucial for planning targeted treatments such as surgery or other interventions.

Why Sleep Endoscopy?

The procedure serves multiple purposes:

  • Diagnostic Value: It provides a dynamic assessment of the upper airway, not possible through static imaging methods like MRI or CT scans.
  • Treatment Planning: Helps tailor treatments to the patient’s specific anatomical and physiological characteristics.
  • Evaluating Treatment Effectiveness: Can be used as a follow-up tool to gauge the success of interventions like CPAP or surgery.

Benefits of Sleep Endoscopy

  • Minimally Invasive: No incisions are required.
  • Personalized Insight: Real-time observations can result in a more tailored treatment approach.
  • Safe: The procedure has a low risk profile and is generally well-tolerated by patients.

Risks and Considerations

  • Sedative Reaction: Adverse reactions to the sedative used are possible but rare.
  • Discomfort: Some patients may experience minor discomfort due to the endoscope.
  • Inconclusive Results: The induced sleep state is not a complete substitute for natural sleep, and results may occasionally be inconclusive.

What to Expect During the Procedure

  • Preparation: Fasting for a few hours before the procedure may be necessary.
  • Duration: The entire procedure usually lasts between 20 to 60 minutes.
  • Sedation: A mild sedative is administered intravenously to induce a sleep-like state.
  • Observation: The endoscope is inserted, and observations are made by the healthcare team.

Post-Operative Care

  • Monitoring: Patients are monitored for a short period after the procedure for any adverse reactions to the sedative.
  • Results Discussion: Findings are generally discussed during a follow-up appointment.
  • Next Steps: Depending on the results, a treatment plan, possibly involving surgery or other interventions, will be proposed.

Frequently Asked Questions

Is the procedure painful?
Generally, patients report minimal discomfort, often equating the sensation to that of a nasal spray.

Is Sleep Endoscopy covered by insurance?
Coverage varies by provider and should be confirmed before scheduling the procedure.
