Facial depression correction by using free anterolateral thigh adipofascial flap and human acellular dermal matrix / 中华医学美学美容杂志

ABSTRACT

Objective:To investigate the clinical effect of facial depression correction by using free anterolateral thigh adipofascial flap and human acellular dermal matrix.Methods:Nineteen facial depression patients (3 males and 16 females), age ranges from 16 to 56 years (average age 29.1±10.37 years), caused by different reasons were selected in this research from Jan. 2008 to Dec. 2020. In the stage I operation, anterolateral thigh adipofascial flap was designed according to facial depression area and harvested to fill in the depression with vascular anastomosis; In the stage II operation, the human acellular dermal matrix was used to fill in the remained depression edge according to facial subunit.Results:All free anterolateral thigh adipofascial flap survived well. All patients revealed fascial subunit tissue atrophy of different degree in infraorbital, nasolabial sulcus and temporal areas which were repaired by using cellular dermal matrix and obtained satisfying effect during 1 to 8 years of follow-up with no obvious rejection. 18 of 19 patients showed flap hypertrophy and corrected by liposuction. All patients recovered well after 1 to 8 years of follow-up.Conclusions:Humana cellular dermal matrix could make up the limitations of treating fascial depression deformity when using anterolateral thigh adipofascial flap. The combination method of above approaches could obtain satisfying clinical effect, which is worthy of clinical promotion.
