Sleep Surgery
Assessment and treatment of snoring and obstructive sleep apnea — from sleep study and weight and positional measures through to airway surgery where it is genuinely indicated.
Snoring is common and usually harmless. Obstructive sleep apnea is neither — untreated, it is associated with high blood pressure, cardiac disease, stroke and daytime accidents, and it is substantially under-diagnosed. The two are not the same condition, and the single most important step is establishing which one you have, because the treatments diverge completely. Dr. Satish Babu is a member of the Indian Association of Surgeons for Sleep Apnea and manages the surgical end of this spectrum, but a sleep study comes before any discussion of an operation. For a significant number of patients the effective treatment is CPAP or weight reduction, not surgery.
Snoring is the sound produced when relaxed tissues in the upper airway vibrate during breathing. Simple snoring, without breathing interruption, is largely a social problem rather than a medical one. Obstructive sleep apnea (OSA) is different: the airway repeatedly collapses during sleep, breathing stops for ten seconds or longer, oxygen levels fall, and the brain briefly rouses to restore the airway — often hundreds of times a night, usually without the person remembering. The result is fragmented, non-restorative sleep and a measurable cardiovascular and metabolic burden. The two are distinguished by a sleep study (polysomnography), which counts the number of apnea and hypopnea events per hour to give the AHI, and grades severity as mild, moderate or severe. Treatment follows from that number and from where in the airway the obstruction sits — nose, palate, tongue base, or a combination — which is assessed by endoscopic examination.

What is involved
An overnight sleep study measuring breathing, oxygen levels and sleep architecture to establish whether apnea is present and how severe it is. This is the foundation of the diagnosis and precedes any decision about treatment.
Endoscopic examination to identify where the airway actually collapses — nose, palate, tonsils, or tongue base. Without knowing the level of obstruction, surgery is guesswork.
Continuous Positive Airway Pressure remains the most effective treatment for moderate to severe obstructive sleep apnea. Where CPAP is indicated, support with fit, tolerance and adherence comes before any surgical alternative is considered.
Septoplasty and turbinate reduction to relieve nasal obstruction. Improving the nasal airway can reduce snoring and, importantly, makes CPAP far easier to tolerate for those who need it.
Uvulopalatopharyngoplasty and related palatal procedures to address obstruction at the soft palate level, performed where the site of collapse has been demonstrated and conservative measures have not succeeded.
Removal of obstructing tonsils and adenoids — the single most effective treatment for sleep-disordered breathing in children, and useful in selected adults with significant tonsillar enlargement.
Before You Agree to an Operation
Airway surgery for snoring and apnea has a mixed reputation precisely because it has historically been offered without adequate assessment. These are the circumstances in which surgery is usually not the answer.
No. Many people snore loudly without any breathing interruption, and simple snoring carries no established cardiovascular risk. Equally, apnea can occur without dramatic snoring. The features that raise concern are witnessed breathing pauses, waking with a gasp, excessive daytime sleepiness, and poorly controlled blood pressure. A sleep study is the only reliable way to settle the question, and it is worth doing before assuming either way.
Surgery can improve sleep apnea considerably in appropriately selected patients — particularly where there is a clear anatomical obstruction such as large tonsils or significant nasal blockage. It is less reliably curative in moderate to severe apnea, especially with multi-level obstruction or a high BMI. For most adults with moderate to severe OSA, CPAP remains the more effective treatment, and surgery is considered where CPAP genuinely cannot be tolerated after proper attempts, or as an adjunct to make it workable.
It can be. Sleep-disordered breathing in children is associated with poor concentration, behavioural difficulties, bedwetting and impaired growth, and it is frequently caused by enlarged tonsils and adenoids. It merits assessment, particularly where there are witnessed pauses or restless sleep. That said, mild cases often improve as the child grows and the adenoid tissue regresses, so observation is reasonable in the absence of significant symptoms.
Because the treatment depends entirely on the result. The sleep study establishes whether apnea is present, how severe it is, and how far oxygen levels fall — and that determines whether the appropriate route is conservative measures, CPAP, surgery, or a combination. Proceeding to airway surgery without that information risks operating on someone who does not need it, and missing severe apnea in someone who needs treatment urgently.
