Cancer of the aretromolar trigone is an uncommon head and neck tumor, which has historically been shown to be associated with poor prognosis. Primary surgery followed by postoperative radiation therapy is the tretment of choice. Surgical excision of the primary lesion and ipsilateral neck dissection are done. Reconstruction are done using masseter muscle flap or tongue flap. Postoperatively, most patients (90%) received radiation therapy (51–58 Gy) to the primary side and neck. Adjuvant chemotherapy is offered if histologic signs of aggressive behavior are identified . SCC of retromolar trigone is considered as an aggressive and insidious tumor. The reconstruction of the deficit of the anterior faucial pillar–retromolar area with masseter muscle flap is a reliable, safe and absolutely functional method. Regards and take care
