Abstract:

Objective This study aimed to explore the repair effect of autologous fat transplantation combined with mucosal tissue flap on different degrees of lip atrophy. Methods Fourteen patients with lip atrophy were selected as the research objects. On the basis of the degree of atrophy, they were divided into three types: mild, moderate, and severe atrophy. Different surgical methods were used to restore the lip shape. Fat transplantation was conducted for patients with mild atrophy. Patients with moderate atrophy were treated with fat transplantation combined with lip mucosal extrapolation. For patients with severe lip atrophy, fat transplantation combined with lip mucosal extrapolation was used in the first stage, and the adjacent mucosal tissue flap transplantation was used in the second stage. Results The appearance and function of the lip of 14 patients recovered well after the operation. Three of them received fat grafting again due to the higher requirements of the patients. All of them were satisfied with the effect after the operation. Conclusion Depending on the different degrees of lip atrophy, autologous fat transplantation or combined with mucosal tissue flap to repair lip atrophy deformity could not only achieve a better postoperative effect but also low trauma, low influence on adjacent tissues, good surgical effect, and high patient satisfaction.
