Abstract:
Objective:To observe the effect of the intramucosal approach to the labial corner to correct the drooping lip angle.Methods:A retrospective analysis was performed for 56 patients who underwent sagging labial corner correction surgery at Beijing Qingmu Medical Aesthetic Clinic from March 2019 to December 2021, including 47 females and 9 males, aged 19-62 years. All patients underwent an intramucosal approach to the labial corner with partial or total dissection of the descending angular muscles and fibrous bundles, and suspension of the orbicularis oculi muscle of the labial corner to a new labial angle. After 12 months of follow-up, the angle of lip corner elevation and the width of the mouth cleft were compared before and after surgery, the satisfaction of patients was evaluated, and the incidence of adverse reactions was recorded.Results:All 56 patients successfully completed the operation, and the swelling subsided in 3-10 days, the scar hyperplasia in the operative area regressed in 1-3 months after surgery, and the naturalness of lip corners recovered within 2-4 months. Among them, 7 patients (12.5%) thought that the upward correction was insufficient, 5 cases (8.9%) thought that there was no improvement, and 8 cases (14.3%) thought that there was bilateral asymmetry. The angle of lip angle and the width of the mouth cleft both increased compared with those before operation (all P<0.001). Forty-eight patients (85.7%) were satisfied, 5 patients (8.9%) were effective but not satisfactory, and 3 patients (5.4%) were dissatisfied. All patients did not have adverse reactions such as infection, hematoma, incision dehiscence, crooked mouth, and mouth closure disorder. Conclusion:The intramucosal approach to the lip corner is safe and effective in correcting the drooping lip angle.
