Treating the tear trough: A new classification system, a 6-step evaluation procedure, hyaluronic acid injection algorithm, and treatment sequences.

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.
