Reconstruction following oral cavity cancer resection is essential not only for reconstruction of anatomy but also for preservation of vital functions like swallowing, speech and mastication. Although micro vascular free flaps are gold standard in many cases but not suitable for every patient. So temporalis muscle flap is a reliable regional flap because of it’s excellent vascularity, close proximity to oral cavity straight forward harvest, less donor site morbidity and high surgical outcome. We will present here surgical anatomy, historical back ground, indication, surgical technique and outcome of temporalis muscle flap. We will also share our experiences of 3 patients diagnosed with oral squamous cell carcinoma who underwent ablative surgery followed by immediate reconstruction using the temporalis muscle flap. The reconstructed defects included: ✅ Partial Maxillectomy with Palatal Reconstruction ✅ Buccal Mucosa Carcinoma involving the Upper Gingivobuccal Sulcus ✅ Buccal Mucosa Carcinoma involving the Lower Gingivobuccal Sulcus ✅ Retromolar Trigone (RMT) Carcinoma Results All temporalis muscle flaps survived successfully without total flap loss. The reconstructed defects healed satisfactorily with acceptable functional and aesthetic outcomes. Patients demonstrated good oral intake, improved speech, and satisfactory swallowing following rehabilitation. No major donor-site complications were encountered. Conclusion The temporalis muscle flap remains a versatile, reliable, and cost-effective regional reconstructive option following oral cancer ablation. It provides satisfactory functional and aesthetic outcomes while avoiding the complexity, prolonged operative time, and higher cost associated with microvascular free tissue transfer.
