Transverse Facial Artery Morphometry Based on Head Dimensions and Palpable Anatomical Landmarks
Aesthetic Surgery Journal
|November 5, 2025
Summary
The transverse facial artery (TFA) origin can be estimated using the zygomatic arch and mandibular head. This anatomical knowledge aids in preventing vascular injury during facial procedures.
Area of Science:
- Anatomy
- Vascular Surgery
- Facial Plastic Surgery
Background:
- The transverse facial artery (TFA) is crucial for facial blood supply.
- Its superficial location poses risks during lateral facial surgeries.
Purpose of the Study:
- To locate the transverse facial artery (TFA) origin relative to the mandible and zygomatic arch.
- To establish anatomical references for safe surgical navigation.
Main Methods:
- Cadaveric dissection of 30 hemifaces.
- Marking of the zygomatic arch and mandibular head.
- Measuring vertical distances from the TFA origin to landmarks after latex injection.
Main Results:
- Transverse facial artery (TFA) consistently originated from the superficial temporal artery.
- Mean TFA origin distance: 26.6 mm from zygomatic arch, 17 mm from mandibular head.
Conclusions:
- Transverse facial artery (TFA) visualization is difficult on imaging.
- Palpable landmarks offer reliable approximation of TFA origin.
- Preoperative landmark identification enhances surgical safety and reduces iatrogenic injury.
