Abstract

Background: Ossifying fibromas are uncommon in horses and complete surgical excision with premaxillectomy, maxillectomy or mandibulectomy is recommended. Piezosurgery has been previously used in equines only in one study.

Objective: To report a case of ossifying fibroma treated with piezosurgery and to describe its follow-up.

Study design: Clinical case report.

Methods: A 4-year-old Zangersheide gelding was presented for a mass occupying the space of tooth 202. Histology confirmed the diagnosis of ossifying fibroma, which was removed by resection of soft tissues and a slice of the premaxilla with a piezotome. First intention closure was achieved with a U-plasty between the soft palate and the gingiva. Afterwards, histology confirmed complete removal of the mass.

Results: At 5 months, the horse did not show signs of recurrence. Surgery was easy to perform with the piezotome and the cosmetic result was excellent.

Conclusion: Piezosurgery is a feasible technique for oral surgeries in horses, although more prospective studies are required.
