Abstract

Background: Oral cavity carcinoma represents one of the most prevalent malignancies in the head and neck region, constituting approximately 30-40% of cases. The reconstruction of post-ablative defects plays a pivotal role in determining surgical outcomes. While multiple reconstructive modalities exist for oral cavity rehabilitation, there remains a paucity of literature regarding the application of the facial artery musculomucosal (FAMM) flap in oral cavity reconstruction. Case Presentation: We present a 69-year-old male diagnosed with cT1N0M0 floor of mouth carcinoma who underwent wide local excision with clear margins, bilateral selective neck dissection (levels I, II, III), and subsequent reconstruction utilizing a FAMM flap for floor of mouth rehabilitation. Results: The total operative time was 120 minutes, with flap harvest and inset requiring 50 minutes. Postoperative course demonstrated excellent flap viability at day 10, with no immediate or delayed complications. Final pathological staging confirmed pT1N0M0 floor of mouth carcinoma. The patient was discharged on postoperative day 12 and has remained disease-free during quarterly surveillance over a 24-month follow-up period. Conclusion: The FAMM flap represents an efficacious reconstructive option for small to moderate-sized oral cavity defects, demonstrating favorable outcomes in terms of both functional and oncological parameters.
