The infraorbital hollow refers to the curvilinear depression under the eyes and comprises the tear trough (TT), nasojugal fold and palpebromalar groove. The TT is the medial portion of the infraorbital hollow. It is defined as the depression formed in the medial lower eyelid, lateral to the lacrimal crest and limited in its inferior aspect by the inferior orbital rim, ending in a virtual vertical line projected from the pupillary axis.1 The infraorbital hollow is the upper limit of the mid-face, and there are many anatomical factors that contribute to its formation (Figure 1).
The infraorbital hollows are considered to be one of the most challenging areas to treat due to variable patient factors. It is vital for clinicians to understand the anatomy, patient suitability and appropriate technique for successful treatment. This ensures precise placement of dermal filler for better outcomes…
