Retrospective study examines clinical features and outcomes of free flaps for oral reconstruction, suggesting early intervention is critical.

This study aims to investigate the clinical characteristics and management of free flaps used in oral and maxillofacial reconstruction.
Retrospective analysis of 689 subjects categorized into two groups: no-flap crisis (620 flaps) and flap crisis (80 flaps).
Demographic and clinical data, including medical costs and intraoperative blood loss, were analyzed.
Distribution of flap types and timing of crisis within the flap crisis group were examined.
Overall survival rate of free flaps was 95% (95% CI [93.4–96.6]), with a salvage rate of 49.28% (95% CI [37.2–61.4]).
Significant differences in postoperative length of stay, duration of surgery, medical costs, and intraoperative blood loss were noted between the two groups.
Within the flap crisis group, 94.20% of crises occurred within the first 84 hours, indicating early intervention helps reduce flap failure.
