Rehabilitation of a patient with extensive odontogenic myxoma treated conservatively: A case report with 14 years of follow-up.

Abstract

Odontogenic myxoma is an odontogenic tumor of mesenchymal origin that presents locally invasive behavior. Its treatment is surgical, and the approach can be more conservative or radical. This article presents the rehabilitation of a patient with extensive odontogenic myxoma in the mandible treated conservatively with follow-up for 14 years. A 17-year-old male patient sought care with a painless swelling in the mandibular region causing facial asymmetry. Imaging exams showed a mixed image, with intralesional septa, involving the left anterior and posterior regions of the mandible with a small remaining basilar and lingual bone. An incisional biopsy was performed which confirmed the diagnosis of odontogenic myxoma. Due to the extent of the lesion, a conservative approach was chosen, with excision of the lesion and peripheral ostectomy, with recurrence of the lesion after 48 months, with a new approach being performed. After 14 years of follow-up, without further recurrence of the lesion, the patient was rehabilitated with dental implants and protocol-type prosthesis. Conservative treatment led to bone remodeling and enabled patient rehabilitation with oral implants and an implant-supported prosthesis. Thus, conservative treatment of odontogenic myxomas is a viable alternative for similar cases, and its longitudinal postoperative follow-up is essential.
