BackgroundThe medial thigh is a well‐hidden area. The two most common flaps from this area are the transverse upper gracilis (TUG) and profunda artery perforator (PAP) flaps. Herein, we explored the applications of combined TUGPAP flap to reconstruct large and complex defects in different regions.MethodsBetween November 2015 and May 2017, 28 patients who underwent reconstruction and extensive soft tissue coverage with the TUGPAP flap for the breasts, head and neck, and pelvi‐perineal regions were included. The defects size ranged from 22 to 29 × 6–8 cm. All flaps were based on the two pedicles: the medial circumflex femoral artery for TUG flap and the profunda artery perforator for PAP flap. They were each anastomosed to a set of recipient vessels. A “Y”‐shaped interposition vein graft (YVG) was used if only one recipient artery was available.ResultsThe harvested skin paddle had dimensions ranged from 20 to 30 × 6–9 cm and all flaps survived completely. Postoperative complications included one case each of donor and recipient site seroma, and one case of wound dehiscence. They were all successfully managed conservatively. During an average follow‐up period of 12.7 months, one patient reported permanent paresthesia in the donor site and another developed hypertrophic scar. All patients were able to resume daily activity without major concerns.ConclusionThe combined TUGPAP flap is a safe, effective, and a good alternative to the common workhorse flaps as it offers the potential for a large skin paddle and decent soft tissue volume with low donor site morbidity in a well‐concealed area.

PurposeFree flap reconstruction in head and neck cancer patients with prior tumor resection, neck dissection, and irradiation is clinically challenging. The purpose of this study was to investigate the reliability and outcome of using the anterolateral thigh (ALT) flap and transverse cervical recipient vessels for microvascular reconstruction in patients with depleted vessels in the head and neck region caused by previous surgery and irradiation.MethodsBetween January 2015 and December 2017, microsurgical head and neck reconstruction was performed using the ALT flap and transverse cervical artery (TCA) as the recipient vessel in 15 patients who had undergone previous neck dissections and irradiation for cancer treatment. All patients had a “vessel-depleted neck” resulting from severe scarring and radiation fibrosis. Clinical data of each patient were recorded.ResultsAll ipsilateral TCAs were found to be damage free. Subsequently, free ALT flaps were revascularized using the TCAs. One patient developed venous thrombosis, and another patient developed arterial thrombosis. They were both salvaged within 6 hours postoperatively. No flap failure or mortalities were reported within the 30-day postoperative period. Two patients developed orocutaneous fistula and were further managed with wound care. The mean follow-up time was 11.9 ± 6.0 months (range, 5–23 months). Five patients died during the follow-up period from cancer progression.ConclusionsThe use of the free ALT flap and TCA as the recipient vessel provides favorable microsurgical outcomes in patients with depleted recipient vessels in the head and neck region caused by previous neck dissections and radiation therapy.

IntroductionComposite and large head and neck defects requiring extensive skin‐mucosa coverage are often reconstructed by combining flaps. Herein, we present a simple and reliable two‐stage fibula osteocutaneous (FOC) flap technique to improve the survival of a large skin paddle for oromandibular reconstructions.MethodsFrom October 2011 to September 2016, 47 patients with through‐and‐through oromandibular defects were reconstructed using FOC flaps with large skin paddles. To ensure optimum survival of skin paddles, temporary orocutaneous fistula were left in place and closed during the second stage operation via de‐epithelialization of the skin paddle and suturing of mucosa. Demographic data, operative details, and postoperative complications were recorded.ResultsThe skin paddle dimensions ranged from 20 to 31.5 cm in length and 12 to 17 cm in width with an average area of 430.4 cm2 (range 300–504). The average time between the two stages and hospital stay were 10 days and 14 days, respectively. Complications at the donor site included wound dehiscence (n = 3, 6.4%), partial skin graft loss (n = 3, 6.4%) and hematoma (n = 2, 4.3%). Recipient site complications included two (4.3%) early postoperative venous congestions that resolved after elevation and three (6.4%) partial skin flap necrosis (less than 5% surface area). All complications resolved with bedside conservative management. There was only one take‐back for evacuation of recipient site hematoma (2.1%) but no flap loss.ConclusionTwo‐staged large skin paddle FOC flaps can simplify reconstruction of extensive oromandibular defects by improving the reliability of the sizable skin paddle and negating the need for a second flap.

AbstractIntroductionMicrosurgical reconstruction of complex head and neck defects often requires reliable tissue in multiple spatial configurations to achieve good functional and aesthetic outcomes. In addition to robust perforators, flap inset and wound closure require great caution to minimize complications especially in the presence of trismus with limited space for inset. This report describes the technique and results of our staged approach to flap inset which increases the chance of total flap survival in complex head and neck reconstructions.MethodsFrom February 2010 to August 2016, a total of 53 patients were identified via a retrospective chart review. Patients who were suspected to have a high risk of vascular compromise and subsequently underwent complex head and neck reconstruction with staged inset of anterolateral thigh (ALT) flaps were included. The flap was inset only partially at the recipient site initially with fewer sutures. At a second stage, after neovascularization from surrounding tissue was established, the flap was partially elevated, divided and mobilized on its own pedicle for definitive inset.ResultsFifty‐one patients had complete survival of flaps and had uneventful postoperative course. Six cases required immediate re‐exploration to release wound tension or reposition the pedicle. Of these, 4 flaps were salvaged, 2 failed due to small perforators despite anastomosis revision. The flap survival rate was 96.2% and the average time between 2 stages was 24 days (range, 21–28).ConclusionStaged flap inset can improve free flap survival in complex head and neck reconstructions.
