Piezosurgical partial ostectomy of the incisive bone for an ossifying fibroma removal in a 4-year-old Warmblood gelding.

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.
