Book AppointmentSleep apnea is a serious sleep disorder affecting millions worldwide. Accurate diagnosis is the cornerstone of effective treatment. Drug-Induced Sleep Endoscopy (DISE) offers a precise and detailed assessment of the upper airway during simulated sleep, leading to targeted and successful interventions. In Chennai, Dr. Vidhyadharan Sivakumar at THANC Hospital is a leading expert in utilizing DISE for the diagnosis and management of sleep apnea.
Understanding Sleep Apnea and the Need for Precision Diagnosis
Sleep apnea is characterized by repeated pauses in breathing during sleep, leading to disrupted sleep patterns and potential health complications. Obstructive Sleep Apnea (OSA), the most common type, occurs when the upper airway becomes blocked, often due to the relaxation of soft tissues in the throat.
Traditional diagnostic methods, such as polysomnography (sleep study), are essential for confirming the presence and severity of sleep apnea. However, they don't always reveal the specific anatomical causes of the obstruction. This is where DISE becomes invaluable.
DISE offers several advantages:
- Direct Visualization: DISE allows the surgeon to directly visualize the airway during simulated sleep, identifying the exact sites of obstruction.
- Personalized Treatment Planning: The detailed information obtained from DISE enables the creation of a tailored treatment plan, maximizing the chances of success.
- Improved Surgical Outcomes: By targeting the specific areas of obstruction, surgical interventions can be more precise and effective.
What is Drug-Induced Sleep Endoscopy (DISE)?
DISE is a diagnostic procedure performed under sedation to mimic natural sleep. During DISE, a flexible endoscope is inserted through the nose to visualize the upper airway, including the nasal passages, soft palate, tongue base, and larynx. The airway is observed for collapse patterns, obstructions, and other abnormalities that contribute to sleep apnea.
The DISE Procedure: A Step-by-Step Guide
- Preparation: The patient is assessed for suitability for sedation and the procedure is explained in detail.
- Sedation: A mild sedative is administered intravenously to induce a state of sleep. The level of sedation is carefully monitored throughout the procedure.
- Endoscopic Examination: A flexible endoscope is gently inserted through the nose, allowing the surgeon to visualize the airway.
- Observation and Recording: The airway is observed for collapse patterns, obstructions, and other abnormalities during simulated sleep. The findings are recorded for detailed analysis.
- Recovery: The patient is monitored until they are fully awake and alert.
In my practice, patients often express concerns about the sedation process. Rest assured, the sedation is carefully managed by experienced anesthesiologists, and the procedure is performed in a safe and controlled environment.

Dr. Vidhyadharan Sivakumar is an internationally trained Head & Neck Surgical Oncologist and the Clinical Director & Senior Consultant at THANC Hospital in Chennai. With over 20 years of experience, Dr. Vidhyadharan is a leading expert in the diagnosis and treatment of sleep apnea, including the use of DISE.
His qualifications include:
- MCh (Head & Neck Surgery) - Amrita Institute
- MS (Otorhinolaryngology) - First Mark & Gold Medal - Annamalai University (2009)
- Fellow, Indian College of Robotic Surgeons (FICRS)

Dr. Vidhyadharan's expertise in DISE allows him to provide personalized and effective treatment for sleep apnea patients. He utilizes the information obtained from DISE to tailor surgical interventions, such as Transoral Robotic Surgery (TORS) and multi-level surgery, to achieve optimal results.
The Role of DISE in Personalized Sleep Apnea Treatment
DISE plays a crucial role in personalizing sleep apnea treatment. By identifying the specific sites and patterns of airway obstruction, Dr. Vidhyadharan can develop a treatment plan that is tailored to the individual patient's needs.
Surgical Options Guided by DISE Findings
DISE findings can guide the selection of the most appropriate surgical intervention for sleep apnea. Some common surgical options include:
- Transoral Robotic Surgery (TORS): TORS is a minimally invasive surgical technique that utilizes a robotic system to remove or reposition tissues in the throat, such as the tonsils, tongue base, and soft palate. Dr. Vidhyadharan is highly skilled in TORS and has performed numerous successful procedures.
- Uvulopalatopharyngoplasty (UPPP): UPPP is a surgical procedure that involves removing excess tissue from the soft palate, tonsils, and uvula to widen the airway.
- Tongue Base Reduction: This procedure involves reducing the size of the tongue base to alleviate obstruction of the airway.
- Maxillomandibular Advancement (MMA): MMA is a more complex surgical procedure that involves moving the upper and lower jaws forward to create more space in the airway.
| Surgical Option | Description | DISE Guidance |
|---|---|---|
| Transoral Robotic Surgery (TORS) | Minimally invasive robotic surgery to remove or reposition tissues in the throat. | DISE helps identify specific areas of obstruction in the tongue base, tonsils, or soft palate that can be targeted with TORS. |
| Uvulopalatopharyngoplasty (UPPP) | Surgical removal of excess tissue from the soft palate, tonsils, and uvula. | DISE can determine if the soft palate and uvula are significant contributors to airway obstruction, making UPPP a suitable option. |
| Tongue Base Reduction | Surgical reduction of the size of the tongue base. | DISE is crucial for assessing the degree of tongue base obstruction and guiding the extent of tongue base reduction required. |
| Maxillomandibular Advancement (MMA) | Surgical advancement of the upper and lower jaws. | DISE can help determine if skeletal abnormalities are contributing to airway obstruction and if MMA is necessary to create more space. This is typically reserved for severe cases. |
If you're experiencing snoring or suspect you have sleep apnea, early consultation is crucial. Book an appointment with Dr. Vidhyadharan at THANC Hospital, Chennai.
Non-Surgical Options
While DISE is often used to guide surgical planning, it can also help determine the suitability of non-surgical options, such as:
- Continuous Positive Airway Pressure (CPAP): CPAP is a non-invasive therapy that involves wearing a mask that delivers pressurized air to keep the airway open during sleep.
- Oral Appliances: Oral appliances are custom-fitted mouthpieces that reposition the jaw and tongue to prevent airway obstruction.
DISE can help identify patients who are unlikely to benefit from CPAP or oral appliances, allowing for a more targeted approach to treatment.

Understanding the Risks and Benefits of DISE
As with any medical procedure, DISE carries some potential risks, although they are generally minimal. These risks may include:
- Adverse reaction to sedation: Although rare, some individuals may experience an allergic reaction or other adverse effects from the sedative medication.
- Nasal discomfort: Some patients may experience mild discomfort or congestion in the nasal passages following the procedure.
- Bleeding: There is a small risk of bleeding from the nasal passages.
The benefits of DISE, however, far outweigh the risks. DISE provides valuable information that can lead to more effective treatment for sleep apnea, improving sleep quality, reducing daytime sleepiness, and lowering the risk of associated health complications.
What to Expect After DISE
After DISE, patients are typically monitored for a short period until they are fully awake and alert. It is important to have someone drive you home after the procedure, as the sedative medication can impair your ability to drive safely.
You may experience some mild grogginess or fatigue for a few hours after the procedure. It is also common to have some nasal congestion or discomfort. These symptoms typically resolve within a day or two.
Dr. Vidhyadharan will discuss the findings of the DISE with you and develop a personalized treatment plan based on your individual needs.
