Incomplete nasomaxillary dysplasia in a foal.

The research article discusses a rare case of nasomaxillary dysplasia in a foal which was successfully treated through a surgical procedure called conjunctivomaxillary sinostomy.

Understanding the Topic

• The paper talks about an under-studied congenital anomaly in foals called nasomaxillary dysplasia. It’s a condition that affects the development of the nasal and maxillary regions in newborns. The etiology, or cause, of this condition is still unknown.
• Atresia of the nasal punctum is highlighted as the most commonly observed congenital anomaly in the equine nasolacrimal system. This condition involves closure or blockage of the nasal punctum, a small opening in the nostril that allows for drainage of the tears from eyes to the nose.

Significance of the Research

• The study is significant because nasomaxillary dysplasia has not been previously documented in foals. So, this presents a unique case and adds to the limited literature available on this condition in equine medicine.

Method and Outcome

• The foal with the nasomaxillary dysplasia was treated using a surgical procedure called conjunctivomaxillary sinostomy. This surgical technique involves creating a new passage between the conjunctiva (a clear tissue covering the white part of the eye and lining the inside of the eyelids) and the maxillary sinus (an air-filled cavity within the cheekbone). This allows for proper drainage of tears away from the eyes, thus resolving the symptom of epiphora, which is an excessive tearing.
• The study reports that this surgical procedure was successful in resolving the excessive tearing, showing promise for treating this rare condition in the future.
