Digitally guided diode-laser cheiloplasty for correction of upper-lip asymmetry: a case report

Résumé fourni par la source

Background: Lip asymmetry, even subtle, can influence facial expression and self-confidence. While conventional cheiloplasty is associated with higher morbidity, diode lasers offer precise soft-tissue contouring with rapid recovery, and digital symmetry analysis enhances surgical planning. Methods: A 35-year-old woman presented with mild right-sided upper-lip asymmetry accentuated by a labially placed lateral incisor. Seeking an alternative to orthodontic treatment, she took an ImageJ-based assessment to map Cupid's-bow alignment and quantify the deviation. Using this digital guide, gentle contouring of the right upper lip was performed with a 940-nm diode laser as a conservative soft-tissue aesthetic refinement. Results: At one week, the upper-lower lip ratio improved from 1:1.73 to a more harmonious 1:1.58 with enhanced commissural symmetry. At three months, the corrected contour was maintained clinically. Conclusion: Digitally guided diode-laser contouring may provide a conservative, case-specific option for aesthetic refinement of minor lip asymmetry in selected patients.
