Summary
Facial appearance persistence is high after virtual face transplantation, while facial appearance transfer remains low. This study utilized 3D simulations to assess facial resemblance in face transplants.
Area of Science:
- Plastic Surgery
- Medical Simulation
- Facial Reconstruction
Background:
- Concerns exist regarding facial appearance transfer and persistence in face transplantation.
- Previous 2D simulations showed low transfer (2.6%) and high persistence (66%).
- 3D computer simulation may offer more accurate estimations.
Purpose of the Study:
- To evaluate facial appearance transfer and persistence using 3D virtual face transplantation.
- To determine the accuracy of 3D simulations in predicting outcomes.
Main Methods:
- Generated 3D virtual face models from CT angiographs.
- Performed 73 virtual face transplantations using surgical planning software.
- Evaluated resemblance to donor (transfer) and recipient (persistence) by 20 reviewers.
Main Results:
- High overall facial appearance persistence (69.2%) and low transfer (32.4%).
- Mandibular patterns showed highest persistence and lowest transfer.
- Persistence and transfer rates were similar across sexes.
Conclusions:
- Facial appearance persistence is high, and transfer is low in virtual face transplantation.
- Anatomy, not size of aesthetic units, influences appearance transfer and persistence.
- Findings may reassure face transplant recipients and donor families.

Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
