Plain-English summary
Three horses were brought in because they had swelling on their faces and were tearing more than usual. Upon examination, all three showed signs of swelling and X-rays revealed a bony growth at the junction of their facial bones, which was causing a blockage in the tear duct. A special imaging test confirmed that the blockage was at the same spot where the duct passes through this area. The condition was diagnosed as a bony growth at the lacrimomaxillary suture. It's important for veterinarians to consider this type of growth when horses show signs of excessive tearing.
Abstract
CASE HISTORY: Three horses were presented with facial swelling and epiphora. CLINICAL FINDINGS: All horses had facial swellings and radiographic findings consistent with exostosis at the lacrimomaxillary suture, and ipsilateral epiphora. Positive contrast dacryocystorhinography demonstrated that the site of obstruction of the nasolacrimal duct was located where the duct traverses the lacrimomaxillary suture. DIAGNOSIS: Lacrimomaxillary suture exostosis. CLINICAL RELEVANCE: Lacrimomaxillary suture exostosis should be considered as a differential diagnosis in cases of epiphora in horses. Dacryocystorhinography, preferably retrograde and normograde, may be used as an aid to diagnosis.
