RELATÓRIO DE ESTÁGIO CURRICULAR E TRABALHO DE CONCLUSÃO DE CURSO INTITULADO: MANDIBULECTOMIA ROSTRAL BILATERAL EM BOVINO COM FIBROMA OSSIFICANTE

Abstract

Ossifying fibroma (OF) is a benign, fibro-osseous, slow-growing neoplasm that can occur in cattle, causing mandibular deformity, tooth loss, and feeding difficulties. This paper describes the case of a 2-year-and-7-month-old Nelore female presented with a progressively growing mass in the mandibular region, characterized by its firmness and friability. Radiographic, clinical, and laboratory examinations indicated bone involvement of the mandible and incisor teeth, anemia, hypoalbuminemia, hypoproteinemia, and low total plasma proteins. Complete tumor resection associated with bilateral rostral mandibulectomy was chosen. The surgical technique involved osteotomy, tooth extraction, cryotherapy application, and reconstruction of the lingual floor with Wolff pattern suture. The removed mass weighed 3.5 kg, and the histopathological examination confirmed the diagnosis of ossifying fibroma. In the postoperative period, the patient received analgesia, antibiotic therapy, and supportive care, showing good clinical evolution, complete healing, weight recovery, and hematological parameters. The procedure allowed for satisfactory functional recovery without the need for further intervention. This case demonstrates that, despite being invasive, bilateral rostral mandibulectomy is an effective approach for managing ossifying fibroma in cattle, ensuring local control of the lesion and adequate recovery.
