Autologous Fat Grafting for Craniofacial Reconstruction in Oncologic Patients

Area of Science:

• Regenerative Medicine
• Plastic and Reconstructive Surgery
• Oncology

Background:

• Craniofacial tumor removal is surgically complex and often followed by chemo-radiotherapy, leading to significant quality of life impairments.
• Sequelae from cancer treatment necessitate advanced reconstructive techniques for head and neck cancer survivors.

Purpose of the Study:

• To review the biological properties of autologous fat making it ideal for craniofacial reconstruction.
• To outline recent advances in understanding craniofacial fat depot anatomy.
• To summarize methods for fat harvesting, processing, and engrafting in craniofacial reconstruction post-tumor removal.

Main Methods:

• Mini-review of existing literature on autologous fat transplantation in craniofacial reconstruction.
• Analysis of biological properties, anatomical studies, and surgical techniques for fat grafting.

Main Results:

• Autologous fat possesses ideal biological properties for craniofacial reconstruction.
• Advances have improved understanding of craniofacial fat depot anatomy.
• Various fat harvesting, processing, and engrafting techniques exist with specific applications, advantages, and limitations.

Conclusions:

• Autologous fat transplantation is a key regenerative medicine strategy for craniofacial reconstruction after head and neck cancer.
• Understanding fat depot anatomy and refining surgical techniques are crucial for successful outcomes in head and neck cancer reconstruction.
