A Novel Approach for Improving Midface Aesthetics: A Pilot Study.

BACKGROUND

Asian individuals often seek solutions to address midface depression and enhance nasal alar base morphology to achieve Western facial aesthetics. Current treatment options, including injections and invasive procedures, have limited efficacy and safety. To address these challenges, we introduced the "modified A-10 surgery," which integrates the Point A-Koji method, titanium plates, and artificial dermis insertion.

METHODS

The efficacy of the modified A-10 surgery was illustrated using a case study of a 22-year-old woman. Surgical planning was based on dental cone-beam computed tomography data, with lateral cephalometric radiographs used to determine the titanium plate dimensions. The surgery involved customized plate alignment, fixation, and artificial dermis insertion.

RESULTS

The modified A-10 surgery substantially improved facial aesthetics and structural parameters. Facial convexity increased from 15.5 degrees to 23.2 degrees, enhancing the 3-dimensionality. The nasolabial angle shifted from 91.9 degrees to 110.2 degrees, achieving the desired mouth projection. Other measurements, such as the E-line to the lower lip and the distance from point A to the subnasal point, contributed to refined aesthetics. The nasal alar base thickness increased by 2.2 mm (19.5%), correcting the depression.

CONCLUSIONS

The modified A-10 surgery represents a minimally invasive and comprehensive solution for midface depression and nasal alar base enhancement. By combining the Point A-Koji method, titanium plates, and artificial dermis insertion, this surgery successfully achieved improved facial aesthetics and contours. The results validate its potential as a long-term solution, with implications for antiaging interventions and promising avenues for future research.
