Background:
Few standardized methods exist for evaluating the postoperative outcomes of osteocutaneous free flaps. We propose an anatomic-based scoring system for midface free flap reconstruction.
Methods:
One hundred and twelve patients across four institutions underwent osteocutaneous reconstruction of the midface. Postoperative scans were scored based on the number of independent osseous subunits reconstructed (Subunit Score), the number of different bony appositions with bony contact (Contact Score), and the number of osseous segments in anatomic position (Position Score). These were added together to create a Total Score.
Results:
Osteocutaneous radial forearm flaps had the lowest Subunit Score (p = 0.001). Fibula flaps had the highest Contact Score (p = 0.0008) and Position Score (p = 0.001). Virtual surgical planning was associated with an increased Subunit Score (p = 0.02) and Total Score (p = 0.04).
Conclusions:
We propose a novel scoring system for osseous midface reconstruction based on postoperative imaging scans. This can help guide management decisions and create a common language to compare outcomes.
