Abstract

OBJECTIVE:

To evaluate the safety and efficacy of polyethylene terephthalate implants in the soft palate to modify disturbing snoring.

DESIGN:

Interventional study, before-after trial.

SETTING:

Referral center, institutional practice, hospitalized care.

PATIENTS:

Twelve consecutive patients with disturbing snoring and an apnea-hypopnea index less than 15 per hour and a body mass index of 30 or less were recruited. One patient with no adverse effects was lost to follow-up. Extrusion of implants occurred in 2 patients. Complete data in 9 patients were available for analysis.

INTERVENTION:

Polyethylene terephthalate implants were inserted in the soft palate.

MAIN OUTCOME MEASURES:

Safety of the procedure and evaluation of the loudness of snoring by bed partners using a visual analog scale.

RESULTS:

There were no complications of infection or bleeding. Extrusion of implants occurred in 2 patients with no clinical sequelae. The mean (SD) loudness of snoring at baseline, as assessed by bed partners using a visual analog scale of 0 to 100, was 79 (17.2). This significantly decreased to 48 (20.4) at 3 months (Wilcoxon signed rank test, P =.008). Daytime sleepiness as measured with the Epworth Sleepiness Scale also decreased from an average score of 8.9 at baseline to 5.7 at 3 months (P =.007). There were no significant changes in the apnea-hypopnea index and body mass index from baseline to 3 months' follow-up.

CONCLUSIONS:

Polyethylene terephthalate implants in the soft palate are safe. Snoring decreased significantly at 3 months after surgery. Polyethylene terephthalate implants in the soft palate should be further explored as a treatment for snoring.
