Abstract:
Abstract Background Free flap reconstruction is the gold standard in head and neck reconstructions. The current article analyzes failed free flaps in the head and neck region during an 11-year period in a single center aiming to discover factors that could be influenced in order to reduce the risk for flap failure. Methods During the 11-year study period, 336 patients underwent free flap reconstruction at Tampere University Hospital, Tampere, Finland. The patients' average age was 62 years (range 14–92 years). Note that 201 (61.5%) of the patients were women and 135 (38.5%) men. Medical records were reviewed for demographics, comorbidities, neoadjuvant and adjuvant therapies, free flap type, area of reconstruction, and intraoperative and postoperative complications. Statistical analyses were performed. Results Ten (3%) of the 336 free flaps failed. Patients' age, comorbidities, smoking, dosage of anticoagulation, free flap type, or the location of the defect did not influence the risk of flap failure. All lost flaps were postoperatively followed by clinical monitoring only. In contrast, 89% of all flaps had both Licox (Integra LifeSciences Corp, NJ) and clinical follow-up postoperatively. In six (60%) of the failed cases, a second free flap surgery was performed as a salvage procedure, with a survival rate of 83.3%. Conclusion Our free flap success rate of 97% is in accordance with that of other centers that perform head and neck reconstructions. According to our findings, free flap reconstructions can be successfully performed on elderly patients and patients with comorbidities. Smoking did not increase the flap loss rate. We encourage the use of other methods in addition to clinical monitoring to follow the flaps after head and neck free flap reconstructions. All flap types used have high success rates, and reconstruction can be conducted with the most suitable flaps for the demands of the defect.Keywords:

SUMMARY:
Head and neck surgical reconstruction is complex, and postoperative imaging interpretation is challenging. Surgeons now use microvascular free tissue transfer, also known as free flaps, more frequently in head and neck reconstruction than ever before. Thus, an understanding of free flaps, their expected appearance on cross-sectional imaging, and their associated complications (including tumor recurrence) is crucial for the interpreting radiologist. Despite the complexity and increasing frequency of free flap reconstruction, there is no comprehensive head and neck resource intended for the radiologist. We hope that this image-rich review will fill that void and serve as a go to reference for radiologists interpreting imaging of surgical free flaps in head and neck reconstruction.Cite

Free-flap microvascular surgery of the head and neck is now an accepted reconstructive technique. Optimal reconstruction of both function and form are achieved in selected patients by this method. We describe our experience with free-flap reconstruction of head and neck defects in 13 patients. In 5 oncologic patients reconstruction was immediate, while in 8 other oncologic and trauma patients it was delayed. The free rectus abdominis myocutaneous flap was used most often. 3 flaps required revision, but only 1 failed.

The purpose of this study was to determine the causes of head and neck free flap loss and to evaluate outcomes after subsequent microvascular and non-microvascular reconstruction.Patients who experienced free flap loss between 2000 and 2012 were reviewed.There were 40 flap losses out of 3090 free flaps (1.3%). Twenty-eight patients underwent subsequent free flap reconstruction of which 27 free flaps were successful (96.4%), which was not significantly different from our initial flap success rate (p = .81). Of patients who underwent subsequent free flap reconstruction for oral/pharyngeal defects, 100% had >80% speech intelligibility and 87.5% were tube feed independent. By comparison, 42.9% of patients who underwent subsequent pectoralis major flap reconstruction had intelligible speech (p = .01) and 25.0% were independent of tube feeds (p = 0.02).Subsequent free flaps after initial free flap losses can be successful in selected patients. Functional outcomes after subsequent free flap reconstruction are favorable compared to pedicled flap reconstruction.

Abstract The lateral arm free flap (LAFF) has been chosen by some head and neck reconstructive microsurgeons to be their fasciocutaneous free flap of choice. The qualities of this flap have been suggested to include its consistent vascular anatomy, its thin and pliable nature, and its reinnervation capabilities, as well as its low donor site morbidity and ease of closure. During the past year we have performed 14 head and neck reconstructions using the extended LAFF (ELAFF). We present our indications for its use and review its shortcomings. Although the ELAFF does have its limitations, including variability in its flap thickness and donor vessel size, it unquestionably is an important flap in head and neck reconstruction and is our flap of choice for soft tissue reconstruction.
