Management of Sleep Disordered Breathing

Sleep-disordered breathing (SDB) is a collective term which includes snoring, upper airway resistance syndrome (UARS) and obstructive sleep apnea syndrome (OSAS). Simply put, the term is describes partial collapse or obstruction of the airway during sleep which may cause sleep problems.

Surgical management was the first treatment modality available for SDB. Some of the first subjects to undergo surgery for an anatomic narrowing or blockage of the upper airway during sleep were those afflicted with the Pickwickian Syndrome (obesity-hypoventilation syndrome). Tracheotomy was the sole surgical procedure available during this period and since it was life saving in these circumstances.   Morbidity and mortality were not established and the tracheotomy was not well tolerated or accepted by most patients even as a method to improve the quality of life or to extend life itself. In the early 70’s the term used to describe nocturnal airway obstruction was hypersomnia with periodic apnea (HPA), later revised to be called obstructive sleep apnea syndrome (OSAS), and now better known collectively as Sleep-Disordered Breathing (SDB).

Over thirty years have passed and our knowledge of sleep disorders has evolved to such an extent that the field of sleep disorders is now a recognized specialty in medicine and a specialty in surgery. Not all patients will accept medical management as the primary first choice, and the same holds true for surgical acceptance. Granted, there is surely a central neurologic mediator associated with this syndrome that is not yet identified. However medical management, the "gold standard", is suffering with compliance problems from the younger subset of patients, who have debilitating daytime somnolence due to Upper Airway Resistance Syndrome (UARS, a mild form of sleep disorder), and do not want to wear a device (CPAP/BiPAP) six to eight hours a night for the rest of their life.

What we have learned about the obstructive process in sleep disorders through the combined efforts of our surgical and medical colleagues, is that nocturnal narrowing or obstruction may be localized to one or two areas, or may encompass the entire upper airway passages to include the nasal cavity (nose), oropharynx (palate) and hypopharynx (tongue base).

Conservative medical therapy is recommended first. Treatment centers around sleep hygiene, weight loss, dental splints and nocturnal pressure devices (CPAP). There are also surgical procedures available to provide for a logical upper airway reconstruction (UAR).2-3 This will usually encompass multiple surgical procedures or sites, in such a manner as to minimize risks and complications. Current established surgical procedures offer reconstruction of the airway from the nose and palatal level to the tongue base.
