Influential Factors on Crease Width Post Cosmetic Blepharoplasty Among Young Asian Women.

[BACKGROUND] Cosmetic blepharoplasty is the most common plastic surgery procedures in East Asian and also one of the procedures most prone to unsatisfactory outcomes. The crease width is a crucial aesthetic criterion for individuals seeking aesthetic enhancements, and due to the various influencing factors, the outcomes of blepharoplasty tend to be unpredictable.

[METHOD] We assessed the apparent height of the double eyelid, incision width, levator muscle function, palpebral fissure height, skin-orbicularis oculi muscle thickness, upper eyelid tissue thickness, and age of Asian women aged 18-35 seeking aesthetic enhancements one-year post-blepharoplasty. A multiple linear regression analysis was performed to explore the relationship between the apparent height of the double eyelid and other variables.

[RESULT] The study revealed a correlation between the apparent width of the double eyelid and the incision width, levator muscle function, skin-orbicularis oculi muscle thickness, eyelid tissue thickness, and age (standardized regression coefficients were 0.423, - 0.566, 0.156, - 0.332, and 0.235, respectively), but not with palpebral fissure height. The multiple regression model had an adjusted R square of 0.695.

[CONCLUSION] The apparent crease width following blepharoplasty is influenced by multiple factors. Therefore, it is essential for the operating physician to comprehensively evaluate the levator muscle function, upper eyelid puffiness, and age of the individual seeking aesthetic enhancement before the surgery. Personalizing the design of the surgical incision height during the procedure is crucial to achieve the desired double eyelid width and morphology.
