About Sleep Apnea Surgery at THANC
Obstructive sleep apnea (OSA) is a chronic disorder characterised by recurrent episodes of upper airway collapse during sleep, leading to partial or complete cessation of breathing. This results in decreased oxygen saturation and fragmented sleep, impacting overall health and quality of life. The severity of OSA is often graded by the Apnea-Hypopnea Index (AHI), with an AHI of 5 to less than 15 events per hour indicating mild OSA, 15 to 30 indicating moderate OSA, and greater than 30 indicating severe OSA. While AHI is a primary diagnostic measure, other factors like oxygen desaturation index (ODI) and daytime symptoms are also crucial in assessing the physiological impact of OSA. Surgical intervention for OSA is typically considered when patients have moderate to severe disease and are unable to tolerate or adhere to CPAP therapy, or when significant anatomical obstructions are identified.
At THANC Hospital, our dedicated sleep and airway team, led by Dr. Vidhyadharan Sivakumar, approaches sleep apnea surgery with a deeply individualised methodology. We understand that OSA is a multi-level problem, and a 'one-size-fits-all' surgical solution is rarely effective. Our comprehensive evaluation includes a detailed clinical examination, polysomnography, and crucially, drug-induced sleep endoscopy (DISE) to dynamically visualise the exact sites and patterns of airway collapse during simulated sleep. This precise diagnostic information allows us to construct a tailored surgical plan, often combining procedures affecting the nasal airway, palate, tonsils, and tongue base, to achieve optimal and lasting improvement in your breathing and sleep quality.

Who Needs Sleep Apnea Surgery?
You may be a candidate if you experience any of the following:
- Moderate to severe obstructive sleep apnea with CPAP intolerance
- Snoring and daytime sleepiness impacting work and driving safety
- Clear, surgically correctable upper airway obstruction
- Enlarged tonsils, palate or tongue base contributing to airway collapse
- Nasal airway block driving CPAP mask failure
- Selected paediatric cases with severe adenotonsillar obstruction and OSA
What to Expect
A clear step-by-step view of your treatment journey at THANC.
- 1
Sleep Evaluation
Your journey begins with a thorough sleep physician review and a comprehensive polysomnography (sleep study) to objectively measure the severity of your sleep apnea, including the Apnea-Hypopnea Index (AHI) and oxygen desaturation events. A detailed upper airway examination is then performed to identify potential anatomical obstructions. Where indicated, drug-induced sleep endoscopy (DISE) provides dynamic visualisation of the upper airway collapse patterns under controlled sleep conditions, offering crucial insights for surgical planning.

Tailored Surgical Plan
Based on the findings from your clinical examination, polysomnography, and DISE, our senior consultants will formulate a highly individualised surgical plan. This plan may involve a combination of procedures targeting specific areas of obstruction, such as nasal airway surgery (e.g., septoplasty, turbinate reduction) for improved airflow, palatal procedures (e.g., uvulopalatopharyngoplasty or palatal stiffening), tonsillectomy, or tongue-base reduction and hyoid suspension to address lower airway collapse. The aim is to create a stable, open airway during sleep.

The Procedure & Hospital Stay
Your surgery will be performed under general anaesthesia by our experienced senior surgeons. The duration varies depending on the complexity and number of procedures involved in your tailored plan. Most patients typically require a hospital stay of one to two nights. During this period, our dedicated nursing team will provide close monitoring of your airway and manage any post-operative pain to ensure your comfort and safety as initial swelling subsides.

Recovery & Sleep Study Review
Initial airway recovery, particularly from palatal and tonsil procedures, can take approximately two to three weeks, during which a soft diet and pain management are essential. A follow-up clinical review is scheduled around six weeks post-surgery to assess symptom improvement and overall recovery. A repeat polysomnography is typically conducted around three months after surgery to objectively confirm the functional improvement in your sleep apnea severity and guide any further management decisions with your sleep physician.
