Chin Microgenia: An Anthropometric Analysis on the Prevalence and Severity in a Chinese Population

Abstract

BACKGROUND The chin is an important component of facial harmony, and deficient chins are associated with unattractiveness. Previous studies have reported microgenia as the most common subtype of chin deformities. OBJECTIVE To investigate the prevalence and severity of microgenia in a Chinese population through facial anthropometric analysis. METHODS A total of 800 Han Chinese adults from various age groups of both sexes were recruited for facial anthropometric measurements and photographic analysis. Chin deficiencies in both sagittal and vertical dimensions were evaluated using G-S-P angle, chin retrusion distance, and Sn-Vl/Sn-Me ratio criteria. RESULTS In the sagittal dimension, microgenia was present in 60.7% of men and 68.6% of women according to the G-S-P angle criterion, and the angle significantly decreased with age in women (p , .05). According to the chin retrusion criterion, microgenia was present in 38.7% of men and 32.3% of women, and the retrusion distance significantly increased with age in both sexes (p , .05). Vertical microgenia was present in 69.6% of men and 81.9% of women according to the Sn-Vl/Sn-Me criterion, and the ratio gradually increased with age in both sexes (p , .05). CONCLUSION Microgenia is common among Chinese, particularly in women, and the prevalence and severity increase with age.

Treating the double chin with hyaluronic acid injection

“…Furthermore, the prevalence of short or retruded chin (microgenia) is very high in Asian populations, with one recent study in China reporting 60%-80%. 20 Microgenia may contribute to lower face and neck sagging, which can worsen SMF appearance; 21 fillers can simultaneously correct microgenia, producing a synergistic effect on patients with both microgenia and SMF.…”

“…In cases of SMF, filler injections over the chin and jawline augment structural support and indirectly strengthens and tightens the skin over the submental region, resulting in reduced SMF prominence. Furthermore, the prevalence of short or retruded chin (microgenia) is very high in Asian populations, with one recent study in China reporting 60%–80% 20 . Microgenia may contribute to lower face and neck sagging, which can worsen SMF appearance; 21 fillers can simultaneously correct microgenia, producing a synergistic effect on patients with both microgenia and SMF.…”

Bipolar Radiofrequency-Assisted Liposuction for Cervical Contouring in Eastern Asians

“…It is also worth mentioning that in the East Asian female population, several patients presented with microgenia or recessed chins. 15 Further, the redundant submental fat and tissue increases with age and blunts the cervicomental angle definition. In patients with microgenia or recessed chins with redundant fat and soft tissue who want face and neck rejuvenation, submental liposuction combined with concurrent genioplasty is more effective.…”

Commentary on “Chin Microgenia: An Anthropometric Analysis on the Prevalence and Severity in a Chinese Population”

“…C hin Microgenia and Anthropometric Analysis on the Prevalence and Severity in a Chinese Population is an excellent article with excellent data and excellent analysis. 1 I strongly recommend that my dermatologic colleagues read this tremendous study. Please do not be scared off by the pages of data and perhaps the unfamiliar landmarks used throughout this study.…”
