Application of Intratissue Laser Ablation in Facial Morphological Modification.

Abstract

Objective: To conduct a retrospective analysis of the therapeutic effects of laser ablation in maxillofacial applications. Methods: Laser ablation was performed in 97 patients, 27 cases of facial fat accumulation, 40 cases of sagging caused by facial aging, 16 cases of soft tissue asymmetry, and 14 cases of facial hyperplasia. Laser parameters were as follows: lipolysis 8 W, 90-120 J/cm², and the ablation of hyperplastic tissue 9-10 W, 150-200 J/cm². The subcutaneous thickness, facial morphology, patient's self-evaluation, and satisfaction were evaluated. Results: Laser ablation reduced the subcutaneous thickness, and tightened loose skin. The patient's appearance looked younger and more beautiful. The curves of the facial contours were more of Oriental beauty. The hyperplasia site became thinner, and the facial asymmetry was corrected or significantly improved. Most of the patients were satisfied with the outcome. There were no serious complications besides swelling. Conclusions: Laser ablation can effectively treat thickening and relaxation of maxillofacial soft tissues. With low risk, few complications, and quick recovery, it can be used as a first-line treatment for maxillofacial soft tissue plastic surgery.
