Enxerto vascularizado de fíbula : estudo de caso.

Abstract

Large tumor resections involving the gnathic bones cause extremely challenging aesthetic and functional defects concerning the rehabilitation. The ideal is to promote intraoperative recons-tructions, which results may be stable in long term. This case study refers to a 28-year-old male patient who complained of pain closed to the tooth 38, compatible with pericoronaritis. Only a part of the crown was visible in the intraoral examination and therefore, the panoramic radiograph was chosen as a complementary exam. Occasionally, the report showed an exten-sive radiolucent image with imprecise limits associated to the retained tooth, which was loca-ted at the angle of the mandible and coronoid process. Intending to solve the tooth impaction through a surgical procedure, its removal was planned as well as the collection of biological material aiming at a more precise diagnostic. Despite the immunohistochemical analysis, the probable diagnosis for the intraosseous lesion is still fibro-histiocitoma bone, even after its complete resection. The surgical planning was composed by immediate reconstruction allied to vascularized graft of fibula at the same operative time. The immediate postoperative period showed a positive evolution and the patient is being through ambulatory follow-up, having controlled clinical and radiographic examination every 6 months.
