Objective To report long‐term outcome in a mare that had extensive rostral mandibulectomy to remove an ameloblastoma. Study Design Clinical report. Animals A 21‐year‐old mare. Methods An ameloblastoma, located in the rostral aspect of the mandible, was removed by complete en‐bloc resection of the tumor, removing most of the mandibular symphysis. Results The day after surgery, the remaining mandibular symphysis (<5 mm) fractured causing marked instability of the hemi‐mandibles. Partial wound dehiscence occurred 5 days after surgery; however, the mare was able to eat well and the incision healed within 2 weeks. At 18 months, there was bony fusion of the hemi‐mandibles and mild protrusion of the tongue. Conclusion Extensive rostral mandibulectomy (up to the caudal edge of the mandibular symphysis) can apparently be performed in a horse without internal or external stabilization, and yield a cosmetic and functional outcome.
