OSAS Surgery

OSAS surgery refers to surgical interventions aimed at correcting anatomical obstructions responsible for Obstructive Sleep Apnea Syndrome (OSAS). OSAS is a disorder characterized by recurrent narrowing or complete blockage of the upper airway during sleep, leading to apneas (pauses in breathing) and hypopneas (shallow breathing).

Obstructions can arise from:

• Soft palate and uvula

   

• Tonsils and adenoids

   

• Tongue base

   

• Nasal passages

   

• Jaw structure

   

The goal of surgery is to restore airway patency, reduce apneic events, and improve oxygenation during sleep. Surgical techniques vary from traditional tonsillectomy and soft palate procedures to advanced multi-level approaches, tailored according to the patient’s anatomy, apnea severity, and response to other treatments.

Why Is OSAS Surgery Performed?

Surgery is typically considered in patients who:

• Do not tolerate conservative treatments like CPAP (Continuous Positive Airway Pressure)

   

• Have anatomically identifiable obstructions

   

• Exhibit moderate-to-severe OSAS with clearly localized airway blockages

   

Common indications include:

• Enlarged tonsils and adenoids

   

• Soft palate or uvula collapse

   

• Tongue base hypertrophy

   

• Deviated nasal septum or nasal obstruction

   

• Constricted jaw structures (retrognathia)

   

Untreated OSAS can result in serious complications such as hypertension, cardiovascular disease, stroke, insulin resistance, daytime sleepiness, impaired attention, and increased accident risk. Surgical intervention aims to prevent these complications and improve overall quality of life.

Preoperative Evaluation for OSAS Surgery

A comprehensive assessment is essential before OSAS surgery. This includes:

1. Medical and Sleep History:

    

   • Snoring frequency

      

   • Daytime sleepiness

      

   • Associated medical conditions

      

2. Polysomnography (Sleep Study):

    

   • Measures apnea-hypopnea index (AHI)

      

   • Evaluates oxygen saturation, heart rate, and sleep stages

      

   • Quantifies severity objectively

      

3. Upper Airway Evaluation:

    

   • Flexible endoscopy

      

   • Drug-Induced Sleep Endoscopy (DISE)

      

   • Imaging: CT or MRI to locate obstruction sites

      

4. General Health Assessment:

    

   • Laboratory tests

      

   • EKG and chest X-ray

      

   • Evaluation by anesthesiology for surgical readiness

      

5. Multidisciplinary Planning:

    

   • ENT specialists, pulmonologists, neurologists, and anesthesiologists collaborate

      

   • Tailored surgical plan is designed based on the location and severity of obstruction

      

Benefits of OSAS Surgery

When performed on appropriately selected patients, OSAS surgery can:

• Significantly reduce apnea and hypopnea episodes

   

• Improve oxygenation and sleep quality

   

• Decrease daytime sleepiness and cognitive impairment

   

• Reduce long-term cardiovascular and metabolic risks

   

• Enhance overall quality of life

   

Success depends heavily on accurate identification of obstruction sites and appropriate surgical technique selection.

Conclusion

OSAS surgery is an effective treatment for obstructive sleep apnea when conservative therapies are insufficient. Comprehensive preoperative evaluation, multidisciplinary planning, and precise surgical execution are key to improving sleep quality, oxygenation, and long-term health outcomes.
