Anterolateral thigh cutaneous flap vs. radial forearm free-flap in oral and oropharyngeal reconstruction: an analysis of 48 flaps.

Microvascular free-flaps have been in clinical use for nearly 3 decades becoming the gold standard in oral and oropharyngeal reconstruction. In this study, a comparison has been made between the radial forearm fasciocutaneous flap with the thinned anterolateral thigh cutaneous flap (tALT), showing the advantage of the anterolateral thigh cutaneous flap in oral and oropharyngeal reconstruction. Between January 2003 and January 2007, 48 reconstructions were performed in patients submitted to surgery for oral and oropharyngeal carcinoma using, in 17 cases, a radial forearm fasciocutaneous flap and, in 31, an anterolateral thigh cutaneous flap. In patients treated with the radial forearm fasciocutaneous flap, results showed 94.1% flap survival; in cases treated with the anterolateral thigh cutaneous flap, 93.5% flap survival (p < 0.9). Functional results, at receiving site, were comparable in both groups. Functional results, at donor site, were less successful in the radial forearm fasciocutaneous flap group, with permanent forearm movement impairment in 35.3% of cases; in the anterolateral thigh cutaneous flap group, only transitory gait impairment occurred in 12.9% of patients. In conclusion, in our experience, the thinned anterolateral thigh cutaneous flap is comparable to radial forearm fasciocutaneous flap in terms of functional results at receiving site, but, having no limitation in availability of donor tissue, it allows a more extended resection of the tumour. Moreover, the donor site can be closed primarily with only an inconspicuous curvilinear scar left over the thigh and with significantly reduced functional impairment.
