# Anatomy-Based Filler Injection: Treatment Techniques for Supraorbital Hollowness and Charming Roll

## TL;DR

This paper discusses filler injection techniques to correct eyelid appearance, focusing on East Asian anatomy and cultural aesthetics.

## Contribution

The paper introduces anatomy-based filler injection techniques tailored for East Asian facial features and cultural preferences.

## Key findings

- Supraorbital hollowness is common in East Asians due to anatomical differences like weaker levator muscles.
- Pretarsal fullness is culturally desirable in East Asian aesthetics and can be enhanced with precise filler injections.
- Anatomical-based filler injections improve eyelid aesthetics and facial harmony when placed correctly.

## Abstract

Supraorbital hollowness and pretarsal fullness, commonly known as the sunken eyelid and charming roll, respectively, are significant anatomical features that impact the aesthetic appearance of the periorbital region. Supraorbital hollowness is characterized by a recessed appearance of the upper eyelid, often attributed to genetic factors, aging, or surgical alterations, such as excessive fat removal during blepharoplasty. This condition is particularly prevalent among East Asians due to anatomical differences, such as weaker levator muscles and unique fat distribution patterns. Pretarsal fullness, also known as aegyo-sal, enhances the youthful and expressive appearance of the lower eyelid, forming a roll above the lash line that is considered aesthetically desirable in East Asian culture. Anatomical-based filler injection techniques are critical for correcting these features, involving precise placement within the correct tissue planes to avoid complications and achieve natural-looking results. This approach not only improves the aesthetic appeal of the eyelid but also enhances the overall facial harmony, emphasizing the importance of tailored procedures based on individual anatomy and cultural preferences.
