Somnoplasty for Snoring

When the soft palate vibrates during sleep, it produces the characteristic sound of snoring, and somnoplasty targets this mechanism directly. The procedure delivers controlled-temperature radiofrequency energy through a needle electrode to the soft palate, uvula, and base of tongue, creating lesions that shrink over several weeks as the body absorbs them.

Unlike traditional surgical approaches, somnoplasty tightens and stiffens these tissues from within, reducing airway vibration without the bleeding, pain, or extended recovery associated with tissue removal.

The Somnoplasty Procedure

Somnoplasty is performed as an outpatient procedure in a clinic setting, typically taking 30–45 minutes from preparation to completion. Local anaesthesia is administered by injection to numb the soft palate and surrounding tissue, with most patients reporting only mild pressure during administration and minimal discomfort once numbness sets in.

The ENT surgeon then inserts a specialised needle electrode into the soft palate at predetermined points, delivering radiofrequency energy at each site before repositioning.

Throughout the procedure, patients remain awake and can communicate with the surgical team at any time, eliminating the risks associated with general anaesthesia and allowing them to return home immediately after treatment.

Candidates for Somnoplasty

Somnoplasty may be suitable for individuals whose snoring originates from soft palate vibration without significant obstruction at other airway levels, typically confirmed through physical examination and a sleep study.

Patients with mild obstructive sleep apnoea (a condition where breathing repeatedly stops and starts during sleep) may benefit from somnoplasty as part of a comprehensive treatment approach, though moderate to severe cases typically require more definitive interventions such as CPAP therapy or more extensive surgery.

Factors That Influence Outcomes

Several individual factors can affect how well somnoplasty works and should be discussed with your ENT surgeon before proceeding:

• Excess weight deposits fat around the neck and throat, compressing the airway independently of soft palate tissue and potentially limiting the benefit of somnoplasty alone
• Significant weight-related airway compression may need to be addressed alongside or before treatment for optimal results
• Nasal obstruction from a deviated septum (when the wall between your nostrils is off-centre), enlarged turbinates (structures inside the nose that can swell), or chronic congestion forces mouth breathing, increasing airflow velocity and worsening soft palate vibration
• Addressing nasal issues either before or alongside somnoplasty may improve overall outcomes
• Alcohol consumption and sedative medications relax throat muscles beyond normal sleep-related changes, potentially reducing the structural improvements achieved through somnoplasty

Recovery Timeline and Expectations

Recovery from somnoplasty is generally straightforward, with most discomfort resolving within the first week and tissue remodelling continuing internally over the following weeks. Patients requiring additional sessions typically schedule these at six to eight-week intervals, with many achieving their final result after one to three sessions.

What to Expect Week by Week

Recovery progresses in distinct stages, and understanding each phase helps set realistic expectations for your results:

• Week 1: Throat soreness typically requires regular analgesic use for three to five days, with a soft diet recommended to minimise swallowing discomfort until normal eating resumes around day three or four
• Week 1 (continued): Temporary voice changes or a feeling of thickness in the throat are common during this initial period
• Weeks 2–4: Initial swelling resolves, but internal tissue remodelling continues — snoring patterns may fluctuate during this time and should not be taken as indicative of final results
• Week 6: Most patients can begin assessing their response to treatment, with bed partners often providing more reliable feedback than self-assessment
• Week 6 (continued): For patients who have undergone sleep studies, a repeat study at this point can objectively measure any changes in airway dynamics

When to Seek Professional Help

• Snoring accompanied by witnessed breathing pauses during sleep
• Excessive daytime sleepiness despite adequate time in bed
• Morning headaches occur regularly
• Gasping or choking sensations that wake you from sleep
• Difficulty concentrating or memory problems that have worsened alongside snoring
• High blood pressure that remains difficult to control

Commonly Asked Questions

How long do somnoplasty results last?

Results typically persist for several years. However, some tissue laxity may recur over time, particularly with weight gain or ageing.

Is somnoplasty painful?

The procedure itself should not be painful due to local anaesthesia. Post-procedure soreness resembles a moderate sore throat and responds well to standard pain relievers.

Can somnoplasty cure sleep apnoea?

Somnoplasty is not recommended as a standalone treatment for moderate to severe obstructive sleep apnoea. Patients with mild sleep apnoea may experience improvement, but a sleep study should guide treatment decisions.

Will I need to take time off work?

Most patients return to desk work within one to two days. Jobs requiring extensive speaking or physical exertion may warrant three to five days off.

How do I know if somnoplasty is right for me?

A thorough ENT examination identifies the anatomical source of your snoring. If soft palate redundancy is the primary cause and you have no significant sleep apnoea, somnoplasty may be appropriate.

Next Steps

Somnoplasty is most effective when soft palate tissue is the primary source of snoring and obstructive sleep apnoea has been ruled out. A sleep study is an essential first step if your snoring is accompanied by pauses in breathing, gasping, or excessive daytime sleepiness. For confirmed soft palate snoring, somnoplasty can be performed without general anaesthesia or an extended recovery, with most patients achieving their final result after 1 to 3 sessions spaced 6 to 8 weeks apart.

If you are experiencing persistent snoring—particularly if accompanied by gasping, choking sensations, or excessive daytime sleepiness—consult with an ENT surgeon who can evaluate your soft palate and upper airway anatomy to determine whether somnoplasty is appropriate for your situation.
