Exploring Drug Induced Sleep Endoscopy: A Key to Uncovering Obstructive Sleep Apnea Solutions

What is Drug-Induced Sleep Endoscopy (DISE)?

Drug-Induced Sleep Endoscopy (DISE) is a minimally invasive procedure that helps diagnose and personalize treatment for obstructive sleep apnea (OSA). With gentle, short-acting sedation that mimics natural sleep, Dr. Egan uses a thin, flexible camera through the nose to watch how your upper airway behaves in real time. This dynamic view pinpoints where and how the airway narrows or collapses—such as the soft palate, tonsils/lateral walls, tongue base, or epiglottis—so your care plan targets the true source of obstruction.

Why DISE matters for Obstructive Sleep Apnea (OSA)

A sleep study measures how often breathing is disrupted, but it cannot show exactly where the blockage occurs. DISE fills that gap. If CPAP is difficult to tolerate or you want to explore alternatives, DISE can reveal the specific pattern of collapse and guide options like oral appliances, tailored surgery, or hypoglossal nerve stimulation (Inspire Therapy). By matching treatment to the anatomy, DISE helps improve comfort, adherence, and outcomes.

How DISE guides a personalized plan

• Identifies the site and pattern of airway collapse (front-to-back, side-to-side, or circumferential).

• Assesses suitability for Inspire Therapy (hypoglossal nerve stimulation). Candidates typically need no complete concentric collapse at the soft palate on DISE and must meet sleep-study and health criteria.

• Predicts response to oral appliance therapy (mandibular advancement) by simulating a gentle jaw-forward maneuver.

• Refines surgical planning by indicating whether the palate, lateral walls, tongue base, or epiglottis needs targeted treatment.

• Evaluates persistent snoring or OSA after prior treatments to avoid unnecessary procedures.

• Coordinates with non-surgical measures such as positional therapy, weight management, and nasal breathing treatments.

Who might benefit from DISE?

• Adults with diagnosed OSA who cannot tolerate or prefer an alternative to CPAP.

• Patients being evaluated for Inspire Therapy.

• People with loud snoring and symptoms of sleep apnea who need targeted evaluation after a sleep study.

• Individuals with ongoing OSA or snoring after surgery or oral appliance therapy.

• Those seeking a precise, anatomy-based plan instead of a one-size-fits-all approach.

What to expect during the DISE procedure

1. 1

   Preparation: You will receive instructions about fasting and medications. Arrange a ride home. Blood thinners and other medicines are managed per your physician’s guidance.

2. 2

   Sedation: Under continuous monitoring, short-acting sedation creates a sleep-like state while you continue to breathe on your own.

3. 3

   Endoscopic exam: A thin, flexible camera is gently passed through the nose to view the soft palate, tonsils/lateral walls, tongue base, and epiglottis while you mimic natural snoring.

4. 4

   Real-time assessment: Dr. Egan documents the level and pattern of collapse and may simulate a jaw-forward maneuver to estimate benefit from an oral appliance.

5. 5

   Recovery: Most patients are ready to go home the same day after a brief recovery. Mild throat or nasal irritation can occur and typically resolves quickly.

6. 6

   Results and plan: Findings are reviewed with you and used to create a tailored treatment plan, which may include medical, dental, device-based, or surgical options.

Safety and possible side effects

• Temporary drowsiness from sedation.

• Mild sore throat, nasal stuffiness, or a small nosebleed.

• Rare risks include breathing changes, aspiration, or medication reactions—your care team monitors you throughout to keep you safe.

• Not everyone is a candidate; Dr. Egan will review your medical history (including heart/lung conditions, pregnancy, allergies, and blood thinners).

After DISE: turning insights into treatment

Your DISE results help focus treatment on what will work best for you. Options may include improving CPAP comfort and settings, an oral appliance (mandibular advancement), positional strategies, allergy and nasal treatments, weight management support, or targeted surgeries (palate techniques, lateral wall support, tongue base reduction, epiglottis procedures). For Inspire Therapy, standard selection typically includes moderate to severe OSA on a sleep study, a BMI within program thresholds, and no complete concentric collapse of the soft palate on DISE. Dr. Egan will review your results and collaborate with you to map a clear path forward.
