Sumario:BACKGROUND: The nasojugal groove or tear trough (TT) area deformity produces visible, pigmented, difficult-to-treat hollows. Hyaluronic acid (HA) filler–based correction yields variable results and complications. We developed an alternative, minimally invasive treatment for this area. METHODS: Patients with significant, visible TT area pigmentation, and/or those requiring corrections for TT filler removal, were given lignocaine-diluted calcium hydroxyapatite (CaHA) fillers. CaHA boluses were placed deep on the bone, under the origin of the orbicularis retaining ligament, and under the sub–orbicularis oculi fat. Diluted CaHA was used as a subcutaneous biostimulatory wash. Efficacy and complications were assessed using the Global Aesthetic Improvement Scale and a modified Tear Trough Rating Scale, at 4 and 18 months. RESULTS: Twelve patients, between 25 and 52 years of age, were treated and showed immediate improvements in hyperpigmentation due to light reflection and some visibility of the filler through skin. Lower eyelid swelling and redness occurred a few days postinjection but resolved spontaneously. Over 4 to 6 months, hyperpigmentation and skin tone, thickness, and color improved noticeably. Global Aesthetic Improvement Scale and modified Tear Trough Rating Scale scores indicated that all patients experienced satisfactory improvements. Three prior HA patients required a second CaHA treatment at 4–6 months for a satisfactory correction, one of whom required a third CaHA “wash” at 10 months. Some mild redness was observed for up to 12 weeks in a few patients; however, no differences in the degree of redness were observed between those treated for dark circles or post-HA correction. One patient experienced a persistent, dull erythema for 8 months; another had overt erythema and swelling following a chest infection which resolved with antibiotics and hydrocortisone cream. No nodules developed in any patient. CONCLUSIONS: We developed an alternative TT deformity treatment that leverages CaHA unique rheology and neocollagenesis-stimulating ability, which lifted and supported the prolapsing orbicularis retaining ligament, improved skin quality, and rejuvenated the periocular area without direct injections into the TT.
