Free Dermal Fat Autografting for Complex Craniofacial Wounds

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Wound Healing

Background:

• Complex craniofacial wounds (CCW) present significant reconstructive challenges.
• Traditional microvascular flap reconstruction for CCW involves substantial patient morbidity.
• Free dermal fat autografting (DFA) is an underutilized but potentially effective treatment for CCW.

Purpose of the Study:

• To evaluate the efficacy and safety of free dermal fat autografting (DFA) in treating complex craniofacial wounds (CCW).
• To assess the outcomes and complication rates associated with free DFA for recalcitrant craniofacial defects.

Main Methods:

• Retrospective cohort analysis of 34 patients undergoing free DFA for CCW between 1985 and 2018.
• Data collected included pre-operative wound complications, graft stability, and therapeutic success.
• Statistical analysis was performed to determine the significance of findings.

Main Results:

• Free DFA achieved a high therapeutic success rate of 85.29% in treating CCW.
• Graft stability was observed in 79.41% of patients at long-term follow-up, with minimal atrophy or necrosis.
• The majority of patients experienced no graft-related complications, indicating low morbidity.

Conclusions:

• Free dermal fat autografting (DFA) is a beneficial and low-morbidity option for complex craniofacial wounds (CCW).
• Pre-operative wound status was a significant predictor of therapeutic success.
• Free DFA should be considered as a viable treatment for recalcitrant craniofacial defects.
