Three-Dimensional Analysis of Tear Trough Volume After Lower Blepharoplasty with Midface Lift.

This study aims to evaluate three-dimensional stereophotogrammetry measured volume changes in the tear trough area after lower blepharoplasty with midface lift with or without orbital fat manipulation. Among patients undergoing midface lift surgery, volume change by three-dimensional photography in the tear trough region was compared between those having no orbital fat manipulation, fat transposition, or fat resection. This is a prospective study of 260 eyelids of 130 patients who underwent cosmetic midface surgery. All patients had an external skin muscle flap midface lift. During the procedure, medial inferior orbital fat was resected, repositioned to a preperiosteal dissection pocket, or not manipulated. Forty-six patients (35.4%) had no fat manipulation, 42 patients (32.3%) had fat preservation with repositioning to the preperiosteal pockets on the medial inferior orbital rim, and 42 patients (32.3%) had fat resection without repositioning. All patients had volume gain in tear trough volume. The amount was not statistically significantly different between fat treatment groups. Mean follow-up time was 12 months (range 6-20 months). Midface lifting improved tear trough volume irrespective of how fat was manipulated.
