TranQuill sling snoreplasty for snoring: A single-arm pilot study for safety and effectiveness

Determine safety and efficacy of the TranQuill Sling Snoreplasty (TSS) (Surgical Specialties Corp., Vancouver, BC, Canada) for the treatment of snoring in adults with benign snoring or mild obstructive sleep apnea.

Prospective, unblinded, single-center pilot study.

From February 2014 to July 2014, 20 adult patients with chronic, disruptive snoring assessed by bed partner were recruited to undergo TSS. Subjects with apnea hypopnea index < 15, minimum oxygen saturation > 85%, and body mass index (BMI) < 32 were included. Outcomes were assessed comparing the results of quality-of-life questionnaires, bed partner-assessed snoring, pain visual analog scales, WatchPAT (Itamar Medical Ltd, Caesarea Ind. Park, Israel) home sleep studies, and flexible endoscopy at baseline and 90-day follow-up.

Thirteen males and seven females were enrolled. Average age was 49.1 (range 31-67) and BMI of 25.8 ± 2.66. TranQuill Sling Snoreplasty significantly reduced snoring symptom scores from 8.70 ± 4.27 to 6.42 ± 4.14, P = 0.012. Snoring visual analog scores demonstrated reduction of 17.8 mm (59.4 mm ± 22.1 to 41.6 mm ± 29.2), P = 0.0184. Thirty-five percent (7/20) of subjects reported complications related to the trial, with no serious adverse events.

TranQuill Sling Snoreplasty is a safe therapy that improves snoring symptoms in most adult subjects with benign snoring or mild sleep apnea. Further study is required to better identify patients likely to respond to the therapy.
