SURGICAL TREATMENT ASSOCIATED WITH LIQUID NITROGEN CRYOTHERAPY IN ODONTOGENIC MYXOMA IN THE MANDIBLE: A CASE REPORT

The odontogenic myxoma is a benign odontogenic tumor, with aggressive characteristics, capable of causing many sequelae with a consequent decrease in a patient's quality of life. The present study aims to report a clinical case of odontogenic myxoma treated by radical surgery in association with liquid nitrogen cryotherapy. A 37-year-old female patient sought dental care with complaints of increased jaw volume but was otherwise asymptomatic. Clinical examination revealed increasing in volume in the vestibular-lingual region of the mandibular symphysis. Radiographically, an extensive multilocular radiolucent area was observed. The proposed treatment was the surgical approach of marginal block resection, with preservation of the mandibular base for bow maintenance, associated with the freezing of the region in order to minimize the risks of recurrence, due to the lack of capsule and lesion's loose consistency. The patient is under a 1-year nonsymptomatic follow-up, without recurrence and rehabilitation with a partial, removable denture.
