| Popis: | BACKGROUND The tear trough is a significant sign of periorbital aging and has usually been corrected with filler injection. However, the arterial supply surrounding the tear trough could be inadvertently injured during injection; therefore, this study aimed to evaluate the nearest arterial locations related to the tear trough and investigate the possibility of severe complications following filler injection. METHODS Thirty hemifaces of 15 Thai embalmed cadavers were used in this study. RESULTS The artery located closest to both the inferior margin (TT1) and mid-pupil level (TT2) of the tear trough was found to be the palpebral branch of the infraorbital artery. Furthermore, at 0.5 mm along the tear trough from the medial canthus (TT3), the angular artery was identified, which was found to be a branch of the ophthalmic artery. The artery at TT1 and TT2 was located beneath both the zygomaticus major and the orbicularis oculi muscles. The distances from TT1 to the artery were measured as follows: laterally, 2.79 ± 1.08 mm along the x axis; and inferiorly, 2.88 ± 1.57 mm along the y axis. For the TT2, the artery was located inferomedially from the landmark of 4.65 ± 1.83 mm along the x axis and 7.13 ± 3.99 mm along the y axis. However, the distance along the x axis at TT3 was located medially as 4.00 ± 2.37 mm. CONCLUSION The high risk of injury to the artery at the tear trough should be considered because of the numerous arteries to this area. |
