Reconceptualizing the Application of Infrahyoid Flap in the Era of Free Flaps in a Developing Country

Objective: To review our clinical experience with infrahyoid myocutaneous flap which is often overlooked in the reconstruction of small to medium-sized tongue, floor of mouth, lower alveolus and gingivobuccal sulcus primary defects. Method: A retrospective study of 12 patients of squamous cell carcinoma involving the tongue, floor of mouth, mandibular gingivobuccal sulcus and alveolus was done in patients who underwent infrahyoid flap as an alternative to free radial forearm flap. This study was conducted in the Tertiary Care Institute. The study included patients treated between March 2020 to May 2021. Patients with T4 and N3 disease, recurrence cases, post-radiation, and chemo-radiation cases who refused to participate in the study were excluded. Results: Out of 12 patients, two patients developed partial flap necrosis. One patient developed a hematoma under the flap and one patient had a neck suture gaping. Postoperative results were found to be phenomenal after one month in all patients. Conclusion: The infrahyoid flap is a dependable, less arduous, and economical option for small to medium-sized defects of the oral cavity. It can be advised as a possible substitute for free flap reconstruction, especially in a developing country where resources are limited.
