Understanding the anatomy of the temporal region, specially the middle temporal vein (MTV), is essential for addressing aesthetic concerns related to facial aging. The temporal soft tissues consist of ten layers with varying thickness, housing important neurovascular structures.
Facial tissues undergo aging at different rates, affecting overall facial appearance. Patients often seek aesthetic interventions for issues like soft tissue atrophy, volume loss, and changes in skin texture and color, leading to a hollow or sunken appearance.
Addressing aesthetic concerns in the temporal region may involve interventions such as temporal augmentation with dermal fillers, fat grafting, or surgical treatments like temporal implants. These interventions aim to restore volume and enhancing overall facial aesthetics.
Venous complications of filler injections in the temporal fossa, although rare, posing significant risks. This is attributed to the presence of the large-caliber venous sinus, the MTV.
Based on the results of the current study, it can be concluded that the venous dangerous zone is located within 1.5 - 3.5 cm above the zygomatic arch. This is because the MTV consistently lies above the most prominent part of the zygomatic arch in all dissected cadavers, with measurements of 22.85 ± 5.32 mm on the right side and 22.19 ± 5.20 mm on the left side. In conclusion, the safe areas for filler injection within the inter-fascial space are within 1.5 cm above the zygomatic arch and, additionally, from 3.5 cm above the zygomatic arch till the temporal crest.
