摘要:Odontogenic myxoma (OM) is an uncommon benign tumor and the adequate management of this lesion is a challenging issue due to the high risk of recurrence. Management varies according to the location and the size of the tumor, patient age, and individual experience, ranging from minimally invasive excisional biopsies to extensive resection. The main goal of mandible reconstruction is to restore continuity of the mandibular arch and restore functionality. Limitations in mouth opening and displacement of the mandibular condyle are common in patients undergoing mandibular reconstruction. Thus, the purpose of this paper is to report a clinical case with maintenance of the mandibular condyle after mandibular resection in the treatment of odontogenic myxoma. An 18-year-old male patient presented in an orthopantomogram, an osteolytic lobulated lesion, well delimited in an ascending branch of the left mandible, with dimensions of about 25 mm × 30 mm, without any clinical sign. The incisional biopsy showed an OM. Then, it was planned and performed a resection of the lesion, with mandibular condyle preservation, and bone graft for jaw reconstruction. The patient is in a 5-year follow-up presenting no recurrence.
