DISE study
DISE (Drug-Induced Sleep Endoscopy) is a diagnostic procedure that allows for a more precise determination of where the airways narrow in cases of snoring or sleep apnea. This enables better planning of further treatment, especially in the case of surgical intervention. The procedure can also be used to assess the effect of snoring appliances and determine their effectiveness.

If you are interested in using snoring splints for the treatment of snoring or mild sleep apnea and want to know if this method is suitable for you a -
Unclear cause of snoring and/or apnea
When the exact cause of snoring or sleep apnea has not yet been determined, and more precise diagnostics are needed to find the most suitable treatmen
How to prepare for your appointment
- Bring your ID card or other identification document.
- Inform the doctor about all chronic illnesses, allergies, and medications you are taking (including over-the-counter drugs and supplements).
- Before the examination, you must fast for 6 hours and not drink for 4 hours, as the procedure is performed under general anesthesia.
- Arrange for transportation home, as you are not allowed to drive yourself after general anesthesia.
What to expect during your appointment
Anesthesia
During the examination, the anesthesiologist puts the patient into superficial anesthesia. Independent breathing is maintained, but muscles relax similarly to natural sleep.
Assessment
The course of snoring and sleep apnea is assessed in both supine and lateral positions. During the procedure, areas of airway narrowing are examined, including the soft palate, base of the tongue, pharyngeal sidewalls, and larynx.
Simulation
The effect of a snoring splint is also simulated, and its impact on snoring/apnea is observed.
Monitoring
After the procedure, the patient is taken to the recovery room, where their condition is monitored until full awakening. The examination is generally safe, but due to the effects of anesthesia, driving is not permitted on the same day.
Recovery
On subsequent days, there are no more restrictions, and the patient can return to their usual activities.

Frequently Asked Questions
Is the DISE study painful?
The study is performed under general anesthesia, so you will not feel any pain. After the procedure, you may experience mild throat irritation.
How long does the study take?
The study itself usually lasts 15-30 minutes, but with preparation and recovery, you may be in the hospital for several hours.
Do I need to do anything before the study?
Yes, you must follow the doctor’s instructions regarding eating and drinking before general anesthesia.
What are the risks of the study?
The risks are mainly related to general anesthesia and endoscopy (e.g., throat irritation, rarely nosebleeds). The anesthesiologist will explain these risks to you before the procedure.
Can I go home immediately after the study?
Yes, it is usually a day-case procedure, and you can go home on the same day, but you are not allowed to drive yourself.
Why is the DISE study necessary?
The DISE study provides the surgeon with a precise overview of which structures narrow the airways during sleep, allowing for the selection of the most effective treatment plan.
