Repair of Loss of Substances of Mandibular Ramus by a Microanastomosis of Fibula Flap: About A Case

Tumors of the cervico-facial region are frequent and their diagnosis is often made at a late stage. Their wide surgical excision leaves often a loss of substances with functional and aesthetic repercussions, difficult to repair by local or pedicle flaps. The use of micro-anastomosed flaps that meet functional and aesthetic imperatives is recommended. In the current study, we report a case of a benign tumor of the Mandibular Ramus in a young patient. The radio-clinical examination was in favor of a benign tumor of the ascending branch of the mandible with invasion of the cortices in places. Histological observation confirmed the nature of this tumor (Keratocyst). The surgical excision required an interruptive resection of the mandibular ramus. Functional (ATM dysfunction and lateral mandibular deviation), and esthetic consequences (left genic depression) were marked. Hence, the use of a micro-anastomosed flap of the fibula (fibula) for the repair of this bone defect should be made.
