Can sleep apnea be treated with surgery?

What Is Sleep Apnea?

Sleep apnea is a serious medical condition characterized by pauses or reductions in breathing lasting 10 seconds or longer during sleep.

It may present with symptoms such as snoring, daytime fatigue, morning headaches, and difficulty concentrating.

This condition not only reduces quality of life but also increases the risk of serious health problems such as cardiovascular disease, hypertension, and diabetes.

Surgical Treatment of Sleep Apnea

So, can sleep apnea be treated with surgery? The answer depends on the patient.

Obstructive Sleep Apnea Syndrome (OSAS) is a serious disorder characterized by repeated collapse of the upper airway during sleep. Treatment options include lifestyle modifications, positive airway pressure therapy (CPAP),and in some cases, surgical intervention. Surgical treatment may be an alternative for patients who cannot tolerate CPAP therapy or who have identifiable anatomical airway obstruction.

Surgical approaches can target different anatomical levels of the upper airway. One of the most common procedures, uvulopalatopharyngoplasty (UPPP),involves reshaping the soft palate and uvula and is primarily aimed at relieving obstruction at the palatal level. In addition, procedures such as genioglossus advancement and hyoid suspension are used to address airway narrowing at the tongue base level. In patients with multilevel obstruction, multilevel surgical approaches may be performed.

The American Academy of Sleep Medicine and other international authorities emphasize that surgery should only be considered after careful patient selection and detailed airway evaluation. Randomized controlled studies have shown that surgery can significantly reduce the apnea-hypopnea index (AHI) in some patients; however, long-term outcomes may vary from patient to patient (Li et al., JAMA Otolaryngology, 2020).

In conclusion, sleep apnea surgery can be an effective treatment option in selected patient groups, but it is not suitable for all patients. The decision should be made by a multidisciplinary team based on the patient’s anatomical features, severity of apnea, and response to other treatments.

What Causes Sleep Apnea?

Sleep apnea usually occurs due to two main mechanisms:

Obstructive Sleep Apnea (OSA): This is the most common type. It occurs when airflow is reduced or blocked due to narrowing or collapse of the upper airway.

Central Sleep Apnea: This occurs when the brain fails to send proper signals to the muscles that control breathing.

In this section, we will focus on surgical options for obstructive sleep apnea, which is seen more frequently.

When Is Surgery Considered in Sleep Apnea?

Sleep apnea is usually diagnosed with a sleep study called polysomnography. It can be classified as mild, moderate, or severe. First-line treatment options generally include:

• Lifestyle modifications (weight loss, reducing alcohol and smoking)
• CPAP therapy (the definitive treatment for moderate and severe OSA, and for selected mild cases; it keeps the airway open during sleep)
• Oral appliances (for mild cases or for patients who cannot tolerate or prefer not to use CPAP)

Some patients may have difficulty tolerating CPAP therapy, or non-surgical treatments may be insufficient due to structural airway obstruction. In such cases, surgical treatment options may be considered.

Types of Surgery Used in Sleep Apnea

Different surgical procedures can be applied depending on the level of airway obstruction:

Uvulopalatopharyngoplasty (UPPP): This is one of the most commonly performed surgeries. It involves removing part of the soft palate and uvula to widen the airway. Its success rate is moderate and it may not be suitable for all patients.

Nasal surgery (septoplasty, turbinate reduction): Performed in patients with significant nasal obstruction to improve airflow.

Tongue base reduction or tongue advancement: Used when airway obstruction is caused by the tongue falling backward during sleep.

Maxillomandibular advancement surgery: The upper and lower jaws are moved forward to permanently enlarge the airway. It is highly effective but a major surgical procedure.

Hypoglossal nerve stimulation (tongue pacemaker): A newer treatment option for selected patients who cannot tolerate CPAP. It stimulates tongue muscles during sleep to keep the airway open.

Who Is Eligible for Sleep Apnea Surgery?

Surgical treatment is considered on an individual basis. It may be an option for:

• Patients who cannot tolerate or do not wish to use CPAP therapy
• Patients with clearly identified anatomical airway obstruction (evaluated by ENT and sleep specialists)
• Patients without significant obesity but with structural airway narrowing
• Young individuals with jaw structure abnormalities

What Is the Success Rate of Sleep Apnea Surgery?

The success of surgery depends on the chosen procedure and the patient’s anatomy. A single surgical intervention may not always provide complete resolution. Symptoms may also recur within 3–6 months in some patients. Therefore, surgical treatment is often combined with other therapies or performed as a multilevel approach.

Sleep apnea is a serious condition that can negatively affect both quality and length of life if left untreated. Treatment must be individualized for each patient. Surgery can be an effective option when appropriate patient selection is made. However, a thorough evaluation by an ENT specialist and a sleep medicine physician is essential before making a surgical decision.
