Comparison of two surgical suture techniques in uvulopalatopharyngoplasty and expansion sphincter pharyngoplasty

Abstract

Background

Uvulopalatopharyngoplasty (UPPP) and expansion sphincter pharyngoplasty (ESP) are two standard surgical procedures for treatment of snoring and sleep apnea. In a prospective clinical trial, we compared a standard simple interrupted suture technique for closure of the tonsillar pillars with a running locked suture.

Methods

Each suture technique was randomly assigned either to the left or the right tonsillar pillars in 28 patients. During the first week, patients were daily checked for suture dehiscence and again on days 10 and 21, the end of followup. Time to perform the sutures was measured intraoperative and surgical complications were recorded.

Results

During followup, suture dehiscence was observed in 15/28 interrupted and 16/28 running sutures (p > 0.5). If a dehiscence occurred during the observation period, the median day of dehiscence was 10 (1 and 3 quartile: 5.75 and 17) days for the interrupted suture and 10 (5–11) days for the running locked suture technique (p > 0.05). The mean (± SD) surgical time for the interrupted suture was 5.2 ± 1.9 and 3.5 ± 1.8 min for the running locked suture (p < 0.001). Postoperative bleedings occurred in 4/28 running sutures and 2/28 interrupted sutures.

Conclusion

The running locked suture technique is an equally safe and time saving way of wound closure in UPPP and ESP.
