Researchers find that inserting three matchstick sized pieces of polyester material in the upper palate is a simple, low cost, and easily tolerated office procedure that provides effective snoring relief.
In a stress filled society, sleep is precious. When your partner or roommate has loud and habitual snoring, finding an effective, minimally invasive and cost-effective treatment becomes critical. Surgery is one option, particularly the uvulopalatopharyngoplasty (UPPP) and laser-assisted uvuloplasty (LAUP), which reduces the pharyngeal tissue volume and increases palatal stiffness through postoperative scarring. However, these procedures are painful and may cause considerable morbidity [define] and functional changes.
Recently developments have resulted in more targeted procedures to stiffen the palate and cause less surgical trauma for patients. These procedures include radiofrequency and injection sclerotherapy of the palate. However, these regimens often require more than one treatment for optimal palatal stiffening, and occasional tissue damage can cause mucosal breakdown and fistulas.
The public has recently been introduced to a new palatal implant system designed to achieve palatal stiffening without tissue damage and volume reduction. This system reduces snoring through placement of permanent implants, which cause fibrosis and submucosal scarring in a single procedure. The implant itself is a segment of braided, polyethylene terephthalate (PET), which has a long history of human implantation. Advantages of this system are expected to be low morbidity, simplicity, and low cost.
But does the palatal system actually work? A research team from Norway set out to evaluate the safety and efficacy of this new treatment for snoring through long-term follow-up. The authors of “Palatal Implants for the Treatment of Snoring: Long Term Results,” are Ståle Nordgård MD PhD, Brit Kari Stene Md, Ketil Wichmann Skjøstad MD, and Vegard Bugten MD, all with the Department of Otolaryngology, Head and Neck Surgery, St Olav University Hospital, Trondheim; and Nina Vanvik Hansen, a research nurse, all in Norway. Their findings are being presented at the American Academy of Otolaryngology-Head and Neck Surgery Foundation Annual Meeting & OTO EXPO, being held September 19-22, 2004, at the Jacob K. Javits Convention Center, New York City, NY.
Methodology:
Thirty-five patients referred to St. Olav University Hospital in Trondheim for habitual snoring were included in this prospective, non-randomised study. A complete medical history and physical ENT examination was conducted on each subject. The patient and his/her bed partner completed questionnaires to evaluate the severity, intensity, duration, and social effects of the snoring. The intensity of snoring and the degree of pain, speech, and swallowing problems were recorded on a visual analogue scale (VAS) from 0 to 10. For snoring intensity, 0 was no snoring and 10 related to an intensity that causes the partner to leave the bedroom. The Epworth Sleepiness Score (ESS) was used to describe the patient’s daytime sleepiness. To evaluate the satisfaction rate, the patients and their partners were asked if they would recommend the procedure to a friend or a family member based on how they felt at the time of follow-up.
The ambulatory, nocturnal polysomnography was performed; follow-up office visits were performed at 2-3 days, 14 days, 30 days, 90 days, 180 days, and 360 days after treatment. These follow-ups consisted of a physical examination and the completion of questionnaires to evaluate the safety and efficacy for the procedure. A polysomnography was repeated at 360 days.
The Palatal Implant System (Pillar™ System) was used in this research study. The implant is 18 mm long and 1.5 mm in diameter. The implant is designed to be permanent while the delivery system is disposable.
