Reconstrução facial com parafusos, fios de aço e polimetilmetacrilato após fratura cominutiva envolvendo osso frontal e nasal em cão: relato de caso.

Abstract

The use of bone grafts in the repair of fractures is a frequent practice in veterinary traumatology and orthopedics. There is a great number of alternatives available in the market, ranging from autogenous and autologous options to biomaterials and synthetic bone substitutes. The assortment of the ideal graft and surgical technique goes with the surgeon's preference. However, it is worth mentioning that polymethylmethacrylate (PMMA) is one of the most accepted materials in literature as a bone substitute in facial reconstruction surgeries, where the use of other synthetic substitutes or autogenous grafts becomes impracticable. The present paper aims to report the use of screws, steel wires and PMMA, as an alternative for grafting, in the facial reconstruction of a dog, with comminuted fractures of frontal and nasal bones, assisted by the surgical service of HV-UFU. The procedure was effective in both bone healing and aesthetics of the patient's face. At the postoperative follow-up, which lasted three months, the patient presented miosis, palpebral ptosis, third eyelid protrusion, endophthalmia and ocular secretion in the left eye, corresponding to the traumatized antimer. Long-term follow-up was not performed due to the discontinuation of treatment by the owner.
