Obstructive sleep apnea: a palatable treatment option?
(1) The Pillar(R) Palatal Implant System consists of three polyester threads that are permanently implanted in the palate (the roof of the mouth) to reduce airway obstruction in individuals with mild to moderate obstructive sleep apnea (OSA) and snoring. (2) Three small, non-randomized uncontrolled trials reported a moderate reduction in the number of breathing interruptions during sleep, three to six months following palatal implant insertion. Statistically significant improvements in daytime sleepiness and snoring intensity were also reported. (3) The minimally invasive surgical procedure causes mild, transient discomfort. A potential complication is partial extrusion of the implant, requiring removal and replacement. (4) Currently, there is insufficient published evidence to determine whether palatal implants are an effective treatment option for patients with mild to moderate OSA due to palatal obstruction. (5) Larger, randomized controlled studies are needed to determine the long-term safety and efficacy of the implants in a more diverse patient population, including those who are obese or those with comorbid medical conditions. Comparisons with existing treatments for OSA are also needed.
