Bilateral rostral mandibulectomy in case of a complete fracture of the pars incisiva in a Simmental fattening bull

Abstract A 9‐month‐old Simmental fattening bull with a history of anorexia, severe salivation and marked bilateral swelling of the mandible was referred to the clinic. The physical examination and radiographs revealed a bilateral complete displaced mandibular fracture involving the symphysis. Treatment consisted of rostral mandibulectomy, including the symphysis, which resulted in a loss of integrity and therefore instability of the hemi‐mandibulae. To promote early food intake and to ensure appropriate analgesia, a multimodal analgesic plan was implemented, and repeated pain scoring was initiated immediately following surgery. The bull was discharged 16 days after surgery, at which point the bull was able to eat normally. The bull showed sufficient weight gain at the end of the fattening period. At slaughter, physical examination showed a stable connection between both sides of the mandibles, and a radiographic examination of the head revealed osseous fusion of both hemi‐mandibulae through a renewal of the symphysis.
