Abstract
Simple SummaryMost data concerning fibula free flaps after cancer resection in the head and neck region are limited to small sample sizes and a short period of follow-up. This retrospective study aims to evaluate the flap success, failure, and complications at the recipient site in 180 cases over 19 years. The flap failure is classified as partial and total flap necrosis. A correlation between flap failure and patients’ medical status, age, sex, BMI, ASA-Score, planning type, and reconstruction time point was performed. Our findings help head and neck surgeons understand the factors that influence flap failure and assess risk factors. Our observations could optimize the treatment of cancer patients receiving a fibula free flap in the future.Fibula free flap (FFF) is widely used in head and neck reconstructive surgery and is considered as a standard and therapy of choice after ablative cancer surgery. The aim of this retrospective monocenter study was to determine the success rates of fibula free flaps for jaw reconstruction after ablative tumor surgery. The disease course of patients who underwent jaw reconstructive surgery with FFF from January 2002 to June 2020 was evaluated regarding the flap success rate. Flap failure was analyzed in detail and categorized into two groups: partial flap failure (PFF) and total flap failure (TFF). A total of 180 free fibular flaps were performed over the last 19 years and a total of 36 flap failures were recorded. TFF occurred in n = 20 (56.6%) and PFF in n = 16 cases (44.4%) cases. No statistically significant differences were found concerning patients’ age at flap transfer, sex, BMI, ASA-Score, preoperative non-virtual or virtual surgical planning (non-VSP vs. VSP), and time of reconstruction (immediately vs. delayed). Duration of hospitalization shows statistically significant differences between both groups (p = 0.038), but no differences concerning operating time and duration on Intensive Care Unit (ICU). Partial flap failure appears to be underreported in literature. Sub- and complete failure of the skin paddle leads to clinical complaints like uncovered bone segments and plate exposure. Partial or complete FFF failure lead to infections on the recipient site and prolonged wound healing and therefore may cause a delay of the beginning of adjuvant radiation therapy (RT). PFF of hard tissue can be induced by RT.
Highlights
Since the first mandibular reconstruction with a fibula free flap (FFF) by Hidalgo in 1989, it has been shown that FFF is a reliable and versatile graft [1,2]
36 flap failures were categorized into the two major groups partial (PFF) and total flap failure (TFF)
The fibula free flap constitutes a standard therapy for jaw reconstructive surgery
Summary
Since the first mandibular reconstruction with a fibula free flap (FFF) by Hidalgo in 1989, it has been shown that FFF is a reliable and versatile graft [1,2]. FFF is considered as standard therapy in head and neck reconstructive surgery, providing the optimal precondition for dental implant success and for oral and dental rehabilitation [3,4]. The flap provides the opportunity to include a septo-cutaneous skin paddle of up to 200 cm. A recent milestone in operative techniques is the possibility of computer-assisted surgery (CAS) and virtual surgical planning (VSP) in reconstructions of jaws [9,10,11]. The support of perforator vessels is crucial. The causes of flap failure are anastomosis insufficiency, more frequent venous congestion (e.g., edema, hematoma), rare arterial occlusion (e.g., embolism, thrombus, kinking), vasospasms, postoperative bleeding, and coagulopathies [17,18,19,20]
