The infrahyoid myocutaneous flap in intra-oral reconstruction as an alternative to free flaps

Abstract

Conclusions: In our experience, monolateral or bilateral infrahyoid myocutaneous flap is less time-consuming and reduces the complication rate and the operation time in both small and large defects if compared with other authors' experience using a microvascular anastomosed flap. Objective: The aim of this study was to describe our results in reconstructive surgery after cancer ablation using the less popular infrahyoid myocutaneous flap as an alternative method to free flaps. The surgical technique and the postoperative outcomes are described. Methods: This was a retrospective study: 32 patients with squamous cell carcinoma of the tongue were surgically treated using a pure infrahyoid myocutaneous neurovascular flap. Results: The flap was successful in all cases without flap necrosis, fistula or complications in the donor site. After radiation therapy, flap tissues remained sufficiently soft, trophic and mobile. Ultrasound evaluation of tongue mobility, performed at the time of discharge, as well as 3 and 6 months after surgery, showed normal bolus propulsion. Cinefluoroscopy also showed good function of the reconstructed tongue.
