This document addresses nasal surgery for the treatment of obstructive sleep apnea (OSA) and snoring.
Note: Please see the following related documents for additional information:
Not Medically Necessary:
Nasal surgery employing any technique is considered not medically necessary for the treatment of snoring.
Investigational and Not Medically Necessary:
Nasal surgery employing any technique, including nasal valve surgery, septoplasty, turbinectomy, polypectomy and laser or radiofrequency ablation (volumetric tissue reduction) of the nasal turbinates is considered investigational and not medically necessary for the treatment of obstructive sleep apnea and other sleep related breathing disorders.
Studies suggest stimulation of receptors in the nasal airway improves muscle tone in the oropharynx, and increased nasal resistance results in increased negative intraluminal pressure, causing an increased tendency for the soft tissues of the upper airway (soft palate and pharyngeal walls) to collapse. In addition, nasal obstruction may lead to mouth breathing, and mouth opening, which, in turn, results in inferior movement of the mandible with associated decrease in pharyngeal diameter. The base of the tongue may also fall backwards reducing the posterior pharyngeal space. The rationale for nasal surgery is to improve nasal patency re-establishing physiological breathing and minimizing oral breathing during sleep; also to reduce nasal resistance and improve the negative intraluminal pressure which generates upper airway collapse.
However, studies have not demonstrated that reducing nasal obstruction and resistance from various causes and using various techniques, (e.g., septoplasty, turbinectomy, polypectomy, RFVTR of inferior nasal turbinates) correlates with a significant reduction in objective OSA indicators, such as the Apnea-Hypopnea Index (AHI) or nocturnal oxygen desaturation. Although some case reports have suggested that surgical correction of nasal obstruction may improve subjective daytime complaints in individuals with OSA, studies in general have been flawed by relatively small numbers of study subjects, the fact that nasal surgery is often performed in association with other surgical procedures, and lack of objective data regarding nasal resistance and OSA diagnostic variables.
In their June 2003 review article, Chen and Kushida concluded that, "The exact role obstructed nasal breathing plays in the pathogenesis of OSA type sleep disorders remains presumptive, and robust clinical studies to evaluate the contribution of nasal function remain elusive. More stringently controlled studies are needed." Another review by Rappai concluded that, "To date, there are no compelling data to demonstrate causality between nasal obstruction and persistent sleep disordered breathing." They point out that most of the studies reviewed in their 2003 review article are short term, or only examined subjective outcomes to evaluate the effect on sleep disordered breathing. The authors concluded that further studies are needed to prove specific causality. There continues to be a lack of large, well designed clinical trials sufficiently powered to support the safety and efficacy of nasal surgical procedures for OSA.
Another proposed use of nasal surgical procedures is to improve compliance with continuous positive airway pressure (CPAP) use in individuals with OSA and nasal obstruction requiring high CPAP settings. To date, CPAP intolerance has been investigated in small retrospective studies with some favorable evidence showing reduced postoperative CPAP titration levels by at least 1 cm water. However, variable additional factors also impact CPAP compliance, such as individual perception of symptoms and improvement in sleepiness and daily function from initial use of CPAP. For these reasons, larger, well designed studies are needed to confirm the durability of any beneficial effect on CPAP compliance from nasal surgical procedures for individuals with OSA (Friedman, 2009; Masdon, 2004; Weaver, 2008; Zonato, 2006). An updated search (in 2012) of the published evidence has not provided additional scientific support for nasal surgical procedures for the treatment of OSA or snoring.
In addition to the above peer reviewed literature, the Institute for Clinical Systems Improvement (ICSI) published a guideline that addresses the topic of nasal surgery for sleep apnea (ICSI, 2008), the authors of which conclude, "There are no studies demonstrating the efficacy of tongue base radiofrequency ablation (RFA) or RFA turbinoplasty for treatment of OSA/Hypopnea syndrome (OSA/HS)…There are no controlled studies that evaluate the long-term effect of septoplasty on OSA." The guideline mentions that RFA of the soft palate has been used primarily for the treatment of snoring, and that perforation and tissue erosion are complications of this technique (ICSI, 2008).
It has been postulated that increased nasal resistance may contribute to, or be causative in, sleep related breathing disorders, such as OSA. Nasal procedures that have been performed for the treatment of OSA include the following:
Chronic: Refers to persistent conditions with symptoms that last over a long period of time.
Nasal turbinates: The scroll-like bony plates with curved margins on the lateral wall of the nasal cavity.
Sleep apnea: Temporary stoppage of breathing during sleep, which can result in excessive daytime sleepiness.
