Background: Free tissue transfer has become the preferred option for complex reconstructions in head and neck cancer ablation. This study reviewed the surgical outcome and analyzed the evolution of microsurgical head and neck reconstruction over 20 years in single institute. Patients and Methods: A total of 1,918 patients underwent microsurgical head and neck reconstructions in 20-year period. The surgical outcome and complications among these 2,019 flaps (1,223 anterolateral thigh flaps, 372 fibula flaps, 353 radial forearm flaps, 12 jejunal flaps, and 59 others) were retrospectively reviewed and analyzed. Results: A total of 201 cases required emergent surgical reexploration and the overall flap success rate was 96.2%. Venous insufficiency was the most common cause for re-exploration. Other major complications included fistula formation (5.4%), partial flap necrosis (7.5%), and infection (17.8%). The fibula flap had frequent complications compared with soft tissue flaps. The familiarity to the ALT flap had minimized complications and allowed for widely versatile uses. Conclusion: Free tissue transfer is shown to be highly reliable option for head and neck reconstruction. For soft tissue defect, ALT flap is the first choice. Fibula flap is ideal for bone defect reconstruction. In case of complex composite defects, double flaps, which include ALT and fibula flaps could reconstruct bone and soft tissue defects simultaneously with high success rate.

Free tissue transfer has become a popular technique for soft tissue defect reconstruction in head and neck cancer ablation. Although high success rates and good reliability of free flaps are proven, microvascular thrombosis is still the most critical issue for microsurgeons. Pharmacological antithrombotic agents are widely used but their efficacy is still debated. In this study, we analyzed whether prostaglandin‐E1 (PGE1) and dextran‐40 can improve the outcomes compared to no antithrombotic therapy at all. We retrospectively reviewed 1,351 free flaps performed for head and neck reconstruction after cancer ablation. Three groups defined were 232 flaps received PGE1, 283 flaps received dextran‐40, and 836 received no antithrombotic therapy. The demographics of these three groups indicated no statistical differences. The results showed that flap survival revealed no significant difference among PGE1, dextran‐40, and control group (P = 0.734). There was a tendency to hematomas in PGE1 group (P = 0.056) when compared with other two groups. Dextran‐40 significantly increased flap failure rate in high‐risk patients with diabetes mellitus (P = 0.006) or hypertension (P = 0.003), when compared with PGE1 and control group. These results revealed antithrombotic therapy with PGE1 and dextran‐40 do not determine a significant improvement in flap survival. © 2012 Wiley Periodicals, Inc. Microsurgery, 2012.

The anterolateral thigh flap with vascularized fascia lata provides a reliable fascial component for single-stage reconstruction of complex soft-tissue defects.

Predicting pathogens in SSI using preoperative oral swabs did not demonstrate a good concordance in general for patients undergoing clean-contaminated head and neck surgery, although concordance for certain pathogenic species seem to be higher than for typical intraoral commensals. The rapid development of resistance to clindamycin precludes its use as a prophylactic agent.

Jejunal flap has a significantly lower rate of stricture for reconstruction of circumferential pharyngeal defects when compared with RFF or ALT flaps.

Oromandibular reconstruction resulting from resection of benign tumor, malignant cancer, osteomyelitic or osteoradionecrotic mandible remains a challenge for plastic surgeons today. At present, fibula osteocutaneous flap is the perhaps most commonly used technique for oromandibular reconstruction because of its potential for contouring, immediate dental implant placement, and favorable donor site morbidity. In this study, we review the history of oromandibular reconstruction, summarize the characteristics of different osteocutaneous flaps, offer surgical options of different osteocutaneous flaps, and provide reconstructive strategies for different locations of mandibular defects. Furthermore, we give a detailed description of various modifications in oromandibular reconstruction: (1) the myoosseous flap for lateral segmental defect repair may reduce donor site complication; (2) to improve the function of oral commissure in patients with obscure recipient vessels, we modify the fibula osteocutaneous flap with anterolateral thigh flap and combine the tensor fascia lata using one set of recipient vessel for composite oromandibular reconstruction; (3) to decrease the likelihood of neck infection and improve aesthetic result, we add the segmental soleus muscle to the fibula osteocutaneous flap to obliterate and augment submandibular dead space. Lastly, dental rehabilitation considerations associated with mandibular reconstruction have been given to help assist in surgical treatment planning.

Reconstruction of the hypopharynx with the anterolateral thigh flap offers versatility in the coverage of large and complex defects and is associated with minimal donor-site morbidity.
