Surgical Treatments for Sleep Apnoea Beyond CPAP

For many people with obstructive sleep apnoea, continuous positive airway pressure (CPAP) therapy can be difficult to tolerate over the long term due to discomfort, disrupted sleep or difficulty adjusting to the machine. When CPAP intolerance affects treatment consistency, ongoing sleep apnoea symptoms may continue to impact sleep quality, energy levels and overall health.

In some cases, surgical treatment may help address the physical airway obstruction contributing to sleep apnoea. Understanding how different procedures work may help patients explore alternative treatment options beyond CPAP therapy.

Why Do Some Patients Struggle With CPAP?

Continuous positive airway pressure (CPAP) therapy works by delivering pressurised air through a mask to help keep the airway open during sleep. While CPAP is commonly recommended for obstructive sleep apnoea, some patients may find it difficult to use consistently over the long term.

Common reasons for CPAP intolerance may include:

• Mask discomfort or air leakage
• Dry mouth or nasal irritation
• Difficulty adjusting to sleeping with the device
• Claustrophobia or anxiety while wearing the mask
• Disrupted sleep caused by noise or discomfort
• Feeling that sleep quality does not improve despite treatment

For some individuals, the underlying airway obstruction may also involve structural narrowing involving the soft palate, tongue or throat tissues. In these cases, surgery may sometimes be considered to physically widen the airway and reduce collapse during sleep.

CPAP intolerance does not necessarily mean sleep apnoea treatment has failed. Instead, further evaluation may help determine whether alternative therapies or surgical options may be more suitable.

How Can Surgery Help Treat Sleep Apnoea?

Sleep apnoea surgery aims to treat the physical airway obstruction contributing to breathing disruption during sleep. Unlike CPAP therapy, which temporarily keeps the airway open using air pressure, surgery works by widening or stabilising narrowed parts of the airway.

Obstruction in obstructive sleep apnoea can occur at different areas of the upper airway, including the nose, soft palate, tonsils, tongue base and throat walls. Depending on where the narrowing occurs, surgery may help remove excess tissue, reduce airway collapse or create more space for airflow during sleep.

For some patients who struggle with CPAP intolerance, surgical treatment may provide a longer-term, machine-free solution to managing sleep apnoea symptoms and improving sleep quality.

What Surgical Procedures Are Available for Sleep Apnoea?

Several surgical procedures may be used to treat obstructive sleep apnoea depending on the location and severity of airway obstruction. In some cases, a combination of procedures may be recommended to improve airflow and reduce airway collapse during sleep.

• Uvulopalatopharyngoplasty (UPPP)

  Uvulopalatopharyngoplasty (UPPP) is a procedure that removes or reshapes excess tissue around the soft palate and throat. This may help widen the upper airway and reduce obstruction behind the palate during sleep.

• Tongue Base Reduction

  Tongue base reduction aims to reduce excess tissue at the back of the tongue that may narrow the airway during sleep. By creating more space behind the tongue, the procedure may help improve airflow and reduce collapse of the airway during sleep.

• Nasal Surgery

  Some patients with sleep apnoea may also have nasal obstruction caused by conditions such as rhinitis, including allergic rhinitis and non-allergic rhinitis. Procedures such as septoplasty or turbinate reduction may help improve airflow through the nose and support more comfortable breathing during sleep.

• Tonsil Surgery

  Enlarged tonsils or chronic tonsillitis can contribute to airway narrowing in some adults with obstructive sleep apnoea. Removing the tonsils may help create more airway space and reduce obstruction during sleep.

• Hypoglossal Nerve Stimulation

  Hypoglossal nerve stimulation involves an implanted device that helps control tongue movement during sleep. The device stimulates muscles that keep the airway open, helping reduce airway collapse in selected patients with CPAP intolerance.

Who May Be Suitable for Sleep Apnoea Surgery?

Sleep apnoea surgery may be considered for patients who are unable to tolerate CPAP therapy consistently or continue experiencing symptoms despite treatment. Surgical treatment is usually recommended only after careful evaluation of the airway and sleep apnea severity.

Patients who may be suitable for surgery can include those with:

• Moderate to severe obstructive sleep apnoea
• Structural airway narrowing affecting breathing during sleep
• Enlarged tonsils, soft palate collapse or tongue base obstruction
• Persistent snoring and disrupted sleep
• CPAP intolerance or difficulty complying with long-term CPAP use

Before recommending surgery, doctors may perform sleep studies, airway examinations or endoscopic assessments to identify where airway obstruction occurs during sleep. Because airway anatomy differs from person to person, treatment plans are usually tailored to the individual’s symptoms, anatomy and overall health.
