Dorsalis Pedis Free Flap: The Salvage Option following Failure of the Radial Forearm Free Flap in Mobile Tongue Reconstruction
Poster
Presentation Description

Institution: Joondalup Health Campus - Western Australia, Australia

Background: Reconstruction following hemiglossectomy presents significant functional challenges, requiring restoration of tongue mobility, bulk, and contour to optimize speech and swallowing. Commonly utilized is the radial forearm free flap – considered a workhorse flap due to its favorable thinness, long pedicle, and potential for neurotization. The free dorsalis pedis flap is a less frequently used alternative. Case Presentation: We report the case of a 40-year-old male who underwent left hemiglossectomy, floor of mouth resection and selective neck dissection for moderately differentiated squamous cell carcinoma. He initially underwent reconstruction with radial forearm flap. The free flap failed to survive due to prolonged arterial ischemia secondary to thrombosis despite return to theatre for thrombolysis and re-anastomosis. The contralateral radial forearm flap was a less desirable choice following multiple vein and arterial catheter insertions. A free dorsalis pedis artery flap was chosen as a salvage option. Microanastamoses were performed between the dorsalis pedis and facial artery and vein. A second vein anastomosis with the great saphenous vein was recruited. Results: The postoperative course was uncomplicated, with successful flap survival. The functional result was satisfactory – the patient was able to demonstrate satisfactory speech articulation and progress to full oral diet. No foot disability was observed, split thickness graft to the foot has healed. Discussion: This case demonstrates the free dorsalis pedis flap as a valuable and potentially underutilised option for hemiglossectomy reconstruction. The major disadvantage of the dorsalis pedis flap in comparison to radial forearm is possible donor site morbidity, including scarring, pain, delayed healing and walking difficulties. However, when conventional donor sites are unsuitable, the dorsalis pedis flap should be considered as a second line and/or salvage option.
