ABSTRACT
Objective@#To observe the anatomical layers and important vascular structures in the main periorbital regions of the human body, and to provide some anatomical basis for clinical periorbital fat injection.@*Methods@#During January 2018 to December 2018, 12 (24 sides) cadavers (6 males and 6 females, 47.5±11.7 years old) were selected. Their orbital tissues were dissected routinely and microdissected. The important blood vessels and tissues around the orbit were measured by electronic vernier caliper. The related matters needing attention in fat injection filling were analyzed according to references.@*Results@#The main structural areas around the orbit included eyelid, eyebrow and lacrimal groove deformities. The thickness of eyelid skin was (0.09±0.03) mm. The thickness of eyebrow skin was (3.45±0.38) mm. Vascular (diameter ranged from 1 mm to 3 mm) distribution was abundant in this area. The inner diameter of dorsal nasal artery, supraorbital artery and trochlear artery were (0.73±0.42) mm, (0.88±0.37) mm and (0.71±0.51) mm respectively. Facial artery, maxillary artery and superficial temporal artery with internal diameters of (2.96±0.88) mm, (1.92±0.33) mm and (1.35±0.15) mm, respectively.@*Conclusions@#The entrance of upper eyelid injection is usually in the eyebrow tail or middle eyebrow, and fat is injected into the deep surface of orbicularis oculi muscle. The injection range is limited to the medial 2/3 of upper eyelid, the medial 1/3 of lower eyebrow and the lateral part of eyebrow. It is suggested that single layer microinjection of fat (0.5 ml to 1.5 ml) could be used. Lower eyelid fat transplantation is mainly used to correct deformities at the eyelid-cheek junction. The aim is to reduce the V-shaped deformity at the eyelid-cheek junction by increasing the fullness. Injection can be made by blunt needle into the inner, outer and middle part of the deformity. Fat can be injected into SOOF layer or periosteum in the palpebral and cheek sulcus area. The injection volume is 0.5-1.0 ml.
