Description : Check out this medical PowerPoint presentation titled "Surgical Management of Obstructive Sleep Apnea" by Marilene B. Wang, MD.

This medical PowerPoint presentation is about the options for the surgical management of obstructive sleep apnea. Obstructive Sleep Apnea (OSA) is a common sleep disorder that affects millions of people worldwide. It is characterized by partial or complete collapse of the upper airway during sleep, leading to repetitive cessation of breathing, or apnea, resulting in decreased oxygenation and frequent arousals during sleep.

While non-surgical treatment options, such as weight loss, positional therapy, continuous positive airway pressure (CPAP) therapy, and oral appliances, are effective for many patients, surgical intervention may be necessary in some cases.

The surgical management of OSA aims to address the anatomic factors that contribute to airway obstruction during sleep. The following are some of the surgical options available:

Uvulopalatopharyngoplasty (UPPP): This surgery involves the removal of excess tissue from the back of the throat, including the uvula, tonsils, and part of the soft palate. UPPP is most effective for patients with mild to moderate OSA who have enlarged tonsils, elongated uvula, and a thickened soft palate.
Maxillomandibular advancement (MMA): This surgery involves repositioning the upper and lower jaws forward to increase the space in the airway. MMA is most effective for patients with severe OSA and a retrognathic (retruded) mandible.
Nasal surgery: This surgery is designed to improve nasal airflow by correcting a deviated septum, removing nasal polyps, or reducing the size of nasal turbinates. Nasal surgery is most effective for patients with nasal obstruction that contributes to OSA.
Lingual tonsillectomy: This surgery involves removing the tonsil tissue located at the base of the tongue, which can contribute to airway obstruction during sleep.
Hypoglossal nerve stimulation: This is a newer surgical technique that involves implanting a device that delivers electrical stimulation to the hypoglossal nerve, which controls the movement of the tongue. This stimulation can help keep the airway open during sleep.

It is important to note that surgery is not the first-line treatment for OSA, and should only be considered in cases where non-surgical treatments have failed or are not appropriate. The choice of surgical procedure should be tailored to the individual patient based on their specific anatomy and the severity of their OSA.

Slide 14-

Nonsurgical Management Oral Appliances May be as effective as surgical options, especially with sx worse on patient’s back However low compliance rate of about 60% in study by Walker et al in 2002 rendered it a worse treatment modality than surgical procedures Walker-Engstrom ML.

Surgical Management Perioperative Issues High risk in patients with severe symptoms Associated conditions of HTN, CVD Nasal CPAP often required after surgery Nasal CPAP before surgery improves postoperative course Risk of pulmonary edema after relief of obstruction
