Surgical management of compound odontoma in two horses.
ABSTRACT Two horses were admitted for evaluation of mandibular swelling (horse 1) or maxillary distortion (horse 2). Both horses had radiographic evidence of tumors of dental origin that had the appearance of a compound odontoma. Extensive surgical resection was performed for treatment. Horse 1 was treated with 1-stage surgical resection, but an iatrogenic fracture occurred during surgery, which was managed successfully with a type I external fixator and extraoral alimentation. Horse 2 was treated in multiple stages to remove all portions of the tumor. To manage an extensive orosinal fistula, a custom-designed dental bridge was constructed to occlude the fistula. For both horses, the histopathologic diagnosis was compound odontoma. Compound odontomas are benign, locally expansive tumors of dental origin. Compound odontomas can be treated successfully; however, multiple surgeries may be necessary.

ABSTRACT: Take Home Message Oral neoplasia should be considered as a differential diagnosis for masses or necrotic lesions detected during oral examination. Diagnosis should subsequently be made on the basis of ancillary imaging information and histological examination of biopsies. Treatment options are limited, but the prognosis for an acceptable quality of life is fair for horses with benign neoplasia.
