Background:
The tear trough is a prominent structure of the midface. Many surgical and nonsurgical techniques have been devised to efface this feature.
Objectives:
The aim of this study was to define an aesthetically pleasing tear trough and understand the effect of various surgical procedures on its appearance.
Methods:
We undertook a retrospective review of "ideal" subjects (ie, young men and women as well as male and female models) as well as surgical patients undergoing lower blepharoplasty with fat excision, fat transposition, erbium laser resurfacing of the eyelids and midface, or endoscopic midface lifting. Marginal reflex distance-2, lower eyelid length, and nasojugal fold depth were measured and analyzed for all patients.
Results:
The nasojugal fold was significantly less prominent in ideal female models than in all other groups (P < 0.0001). Lower eyelid length was significantly shorter after fat excisional lower blepharoplasty, laser resurfacing, and midface lift (P < 0.0001), and did not change after fat transpositional lower blepharoplasty. Postsurgical reduction in lower eyelid length was significantly less with fat transpositional lower blepharoplasty than in all other groups (P < 0.0001). The nasojugal fold was significantly effaced after all types of procedures (P < 0.0001), but was significantly more effaced after fat transpositional lower blepharoplasty (P < 0.01) than after all other procedures.
Conclusions:
A slight, medial tear trough is present in youth in many patients. The clinical tear trough is a virtual topographic structure distinct from the anatomic tear trough ligament and can be altered in a variety of ways.
