Abstract
Objective: To describe our experience with chimeric flaps and to assess the surgical outcomes and postoperative complications associated with chimeric flaps compared to multiple flaps.
Study design/methods: Patients undergoing chimeric and multiple simultaneous free tissue transfer between June 2016 and October 2023 were retrospectively reviewed. The primary outcome of interest was the complication rate. Major complications required takeback to the operating room, hospital readmission, or transfer to the intensive care unit. Minor complications were managed conservatively. Secondary outcomes included operative time, length of hospitalization, and flap survival.
Setting: Academic tertiary care center.
Results: Our analysis included 113 patients (chimeric n = 38, multiple n = 75). We found no significant difference in operative times or minor complications. Chimeric flaps were associated with a shorter length of hospitalization. The major complication rate was higher for chimeric flaps (42.1% vs 22.7%, P = .03), but each cohort only had 1 instance of total flap loss.
Conclusion: The complexity of large head and neck defects poses a reconstructive challenge for microvascular surgeons. Our findings suggest that chimeric and multiple flaps both produce acceptable complication rates when used appropriately. Differences in complication rates may reflect differences in utilization. The chimeric flap remains a valuable option for those with prior radiation or radical resection, but it remains unclear the degree to which they lessen the inherent risk of postoperative complications within this population. Each technique must be weighed in context of the patient's reconstructive profile and the institution's surgical capabilities to optimize long-term outcomes.
期刊介绍:
Otolaryngology–Head and Neck Surgery (OTO-HNS) is the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation. The mission of Otolaryngology–Head and Neck Surgery is to publish contemporary, ethical, clinically relevant information in otolaryngology, head and neck surgery (ear, nose, throat, head, and neck disorders) that can be used by otolaryngologists, clinicians, scientists, and specialists to improve patient care and public health.
