Drug-induced sleep endoscopy (DISE)

Drug-induced sleep endoscopy (DISE) is a specialized medical procedure used to evaluate and diagnose the causes of obstructive sleep apnea (OSA). Unlike traditional awake endoscopy, DISE involves administering sedative medications to induce sleep-like conditions in the patient. 

Dr Peter advises DISE treatment in Dubai, for sleep apnea when the patient is intolerant or doesn’t respond well to CPAP, sleep apnea treatment. 

DISE or Drug-induced sleep endoscopy allows doctors to observe and assess the upper airway anatomy and function during simulated sleep, providing crucial insights into the underlying issues contributing to sleep-disordered breathing.

What happens in Dr Peter’s DISE treatment in Dubai?

 DISE is an easy procedure in which Dr.Peter injects sedative medications into the patient’s veins to achieve a natural sleep. When the patient starts snoring, an endoscope—a thin, flexible tube with a camera and light—is gently inserted through the nose or mouth and advanced into the upper airway. This allows Dr. Peter to see where the air is collapsing. In some cases, it also allows us to know why CPAP is not working.
Dr. Peter states that DISE is a great advantage!

Purpose and Benefits of DISE

The primary purpose of DISE is to identify anatomical and functional abnormalities in the upper airway that contribute to obstructive sleep apnea. By visualizing the airway under sedation, doctors can pinpoint specific sites of obstruction, such as:

1- Tongue base collapse: This occurs when the tongue relaxes excessively during sleep, obstructing the airway.

2- Palate collapse: The soft palate may collapse backwards, narrowing the airway passage.

3- Lateral wall collapse: Weakness or collapse of the lateral walls of the throat can also contribute to airway obstruction.

4- Epiglottic collapse: When at rest, the epiglottis, a tissue flap that normally covers the windpipe during swallowing, can block the air passage.

Identifying these obstructions is crucial for determining the most effective treatment options for patients with OSA.

It assists healthcare providers in customizing treatments like CPAP, oral appliances, or surgery to target the specific anatomical causes of sleep apnea.

Candidates for DISE

DISE is typically recommended for patients with obstructive sleep apnea who are being considered for surgical intervention or who have not responded well to other treatment modalities like CPAP or oral appliances. It provides valuable information that aids in selecting the most appropriate surgical approach, such as:

  • Uvulopalatopharyngoplasty (UPPP): Surgery to remove excess tissue in the throat to widen the airway.
  • Tongue base reduction: Procedures to reduce the size of the tongue base to prevent it from collapsing backwards.
  • Expansion sphincter pharyngoplasty (ESP): Techniques to stiffen and support the soft palate and throat tissues.

Drug-Induced Sleep Endoscopy Procedure (DISE)

During a drug-induced sleep endoscopy procedure (DISE), patients are sedated with propofol to replicate natural sleep conditions. Under the supervision of an anesthesiologist, a flexible fiberoptic laryngoscope or endoscope is gently inserted through a nostril and guided into the throat.

 This allows surgeons to meticulously examine the upper airway and related structures contributing to obstructive sleep apnea (OSA). By observing these areas while the patient is sedated and breathing comfortably, surgeons can pinpoint specific anatomical issues causing OSA. 

This diagnostic precision helps tailor treatment plans, which may include surgery or targeted therapies, to manage sleep-disordered breathing in individual patients effectively.

Post-Procedure Considerations

After a DISE procedure, patients are monitored until the effects of sedation wear off and they are alert and stable. Some individuals may experience minor side effects from the sedative medications, such as temporary throat discomfort or grogginess. However, these typically resolve quickly.


Drug-induced sleep endoscopy (DISE) is a valuable tool in the management of obstructive sleep apnea. It provides detailed insights into airway obstructions that are not visible during wakefulness. 

DISE helps healthcare providers tailor treatment plans to improve outcomes for patients with OSA by accurately identifying the specific anatomical issues contributing to sleep-disordered breathing. 

If you or a loved one is considering surgical options for sleep apnea, discussing the potential benefits of DISE with a healthcare provider can be a crucial step toward effective treatment.
