(Background and Objectives) The odontogenic myxoma is a benign tumor of mesenchymal origin, locally invasive, recurrent with slow grow. While both jaws can be affected, this tumor is slightly more common in the mandible. If untreated, can achieve big dimensions with great possibility of morphofunctional damage. The therapeutic modalities ranging from curettage to in block resection. The aim of this study is to describe a clinical case of an extensive mandibular segmental resection for treatment of myxoma, its immediate reconstruction with autogenous bone with the preservation of the inferior alveolar nerve. (Methods) The patient was operated by sub-mandibular access, under general anesthesia, and removed a full segment of the mandible, approximately 8 cm, after careful dissection of the nerve. The reconstruction was made immediately through a placement of iliac autogenous bone graft and plate reconstruction. (Results) After 8 months of the procedure the patient meets with normal sensitivity in the region and the perfect integration of the bone block. Later held the installation of osseointegrated implants for rehabilitation of the region. (Conclusion) Even in large resections of the lower jaw, not cancer, it is possible to preserve the nerve with consequent maintenance of the sensitivity of the region, improving life quality for the patient.
