Tear Trough Deformity: Study of Filling Procedures for Its Correction

Abstract The aim of this work is to discuss the anatomy of the tear trough region with relative danger areas, and to describe 2 different options to correct this deformity. The tear trough is a concave deformity of the orbital fat that is noticeable as a result of inherited anatomic differences and aging. However, the periorbital region is a complex area with its own septa and ligaments, fat compartments, muscles, vascularization, and lymphatic drainage and presents anatomic characteristics that must be taken into account in order to achieve good results and avoid complications. The use of hyaluronic acid gel or autologous fat for soft tissue correction is a good option. A total of 96 patients with periorbital hollowing were divided into 2 groups; each group received a different treatment, from December of 2013 to December of 2015, with hyaluronic- or lipo-filling.
