Summary
Introduction
The tear trough deformity is commonly requested for correction, most often by filler injections. However, the tear trough remains difficult to treat due to its complex anatomy, a variety of other concurrent deformities, and the high risk of complications.
Objectives
To create a standardized categorization, evaluation, and treatment protocol for the management of tear troughs with fillers.
Methods
(1) Patient deformity profiles are determined using three categories of traits: A (Atrophy), B (Bulging), L (Laxity). (2) A 6-step evaluation process (Tilt, Snap, Smile, Squint, Pull, Push) aids in ABL determination. (3) Treatment is simplified into a comprehensive protocol for each category (with 6 major injection points and a variety of injection depths and volumes).
Results
The author has achieved satisfactory results using the presented protocols, with photographic examples.
Conclusion
The author proposes a comprehensive categorization system that takes into account both the tear trough and other concurrent deformities. The author also presents 6 tests to aid in categorization, and simple protocols with injection sequences, amounts, and depth.
