Abstract
Background
Complications following head and neck microvascular free tissue transfer (MFTT) are common. Less is known about when they occur.
Method
Retrospective study of patients with primary or recurrent head and neck cancer undergoing MFTT reconstruction at a tertiary care institution. MFTT reconstructions with inpatient postoperative complications were included. The Kruskal–Wallis test was used to compare median postoperative day (POD) onset of complication by flap type.
Results
Of 1090 patients undergoing MFTT reconstruction, 126 (11.6%) patients experienced inpatient complications including fibula (n = 35), anterolateral thigh (n = 60), or radial forearm (n = 31) MFTTs. POD onset was shortest for surgical site hematoma (median = 1 [IQR 1–5]), and longest for donor site infection (median = 11.5 [IQR 8–15]). There was no significant difference between flap types and POD onset of complications (p > 0.05).
Conclusion
Hematoma formation and flap failure occur earliest during hospitalization, while dehiscence, infection, and fistula occur later. There is no difference in complication timing between flap types.
