PURPOSE: To determine whether identification and incorporation of the pyriform ligament in the alar cinch results in decreased alar base widening compared with standard alar cinch techniques.
MATERIALS AND METHODS: This was a retrospective case series and the sample was composed of patients undergoing Le Fort I osteotomy. Intraoperatively, the pyriform ligament was identified and incorporated in the alar cinch suture. Greatest alar width (GAW) measured immediately after closure was compared with GAW measured at least 5 months postoperatively. The change in alar base width was compared with that reported in the literature using other alar cinch techniques. Two case examples are reported.
RESULTS: The sample was composed of 15 patients (mean age, 27.1 yr; 27% female). The mean postoperative change in GAW was 1.0 ± 0.6 mm (2.59 ± 1.59%). Postoperative change in alar base width reported in the literature ranged from 0.5 to 10.8%.
CONCLUSION: The pyriform ligament is easily identified during exposure of the maxilla and pyriform aperture and can be used to control widening of the alar base after Le Fort I osteotomy.
