Aesthetic Outcome of Isolated Advancement Genioplasty With and Without Submental Liposuction in the Treatment of Skeletal Chin Deficiency in Double Chin Patients (A Randomized Controlled Clinical Trial).

This study was conducted to evaluate the effect of submental liposuction with advancement genioplasty versus advancement genioplasty alone on esthetics in double chin patients. Twenty-six patients with deficient chin were included in the study. The patients were distributed into 2 groups: submental fat liposuction in conjunction with advancement genioplasty group as intervention one and advancement genioplasty alone as a control group. Preoperative and postoperative computed tomography was performed for all patients. With the help of various software, diagnosis, virtual planning, and evaluation were done. Patient satisfaction was evaluated by a Face-Q questionnaire. The study was conducted on 26 patients with deficient chin, 88.9% were females and 11.1% were males. The mean age of cases was (25.5±3.5 y), clinically all cases went uneventful, and there were no statistically significant differences regarding soft tissue relapse between the study and control groups. All patients showed statistically significant increases in scores of satisfaction with the chin, psychological well-being, and social well-being scales. Submental fat liposuction can be a good intervention choice in mild-moderate chin deficient cases when added to an advanced genioplasty procedure.
