Objective: To present our application of a double anterolateral thigh (ALT) free flap in reconstruction of a large full thickness defect of the oral cavity, cheek and cervical area.
Methods:
Design: Case Report
Setting: Tertiary Government Hospital
Patient: One
Results: A 77-year-old male with a 20 x 25 cm full thickness soft tissue defect on the facial and cervical area contiguous with a 6 x 6 cm buccal defect resulting from wide tumor ablation of a Stage IVA (T4aN2bM0) squamous cell carcinoma of the buccal mucosa underwent reconstruction using two ALT free flaps. An ALT flap was designed to cover the intraoral and cheek defect, while another ALT flap was used for external coverage of the cervical defect. The first ALT flap measured approximately 8 x 22 cm while the second ALT flap measured 6 x 22 cm harvested from the left and right thigh respectively. Temporary venous congestion was observed on the inferiorly placed ALT flap due to neck edema that spontaneously resolved on the 2nd post-operative day. Minimal donor site complications observed were linear scars, and a 1 x 4 cm dehiscence on the right thigh that healed spontaneously by secondary intention.
Conclusion: The utilization of a double anterolateral thigh free flap allowed single-stage reconstruction of the large soft tissue head and neck defect with little donor site morbidity, shorter operating time and shorter hospital stay.
