Plain-English summary
A young Quarter Horse had a serious dental problem where a piece of a broken tooth got stuck in its upper jaw, creating a hole between the mouth and the sinus. This caused food to get trapped and led to changes in the sinus and some facial deformities. After removing the remaining tooth piece and cleaning out the sinus, the hole didn't heal on its own, so the vets used special tools through the mouth and nose to help it close up. The treatment was successful in encouraging healing of the hole.
Abstract
We report an unusual case of a young Quarter Horse with a large dental fracture fragment displaced into the maxillary sinus, leaving an oroantral communication that caused food impaction and metaplastic calcification in the sinus and facial deformation with cutaneous fistulation. Oral extraction of a remaining tooth fragment from its alveolus was succeeded by a maxillary sinusotomy for removal of the abnormal sinus contents. Since the oroantral fistula did not heal spontaneously following the placement of a silicone dental prosthesis, minimally invasive transbuccal and transnasal endoscopic approaches were used to encourage closure of the oroantral fistula by alveolar granulation. The clinical, diagnostic, and therapeutic features of this case may be helpful to clinicians when dealing with similar cases.
