Cartilago nasi lateralis dorsalis
The dorsal lateral nasal cartilage supports the dorsal and lateral walls of the nasal vestibule and helps maintain the patency of the dorsal nasal meatus; the main airway passage in the horse. It is part of the larger nasal-cartilage complex that keeps the nostrils and nasal passages from collapsing during high-volume breathing. Clinical problems are uncommon in isolation but can occur with trauma, congenital malformation, or as part of broader nasal or alar-fold issues. The cartilage is evaluated during endoscopic examination of the upper airway.
See broader nasal-cartilage and upper-airway entries for full details. Trauma or collapse can contribute to abnormal respiratory noise.
Abnormal respiratory noise at exercise, especially if it sounds like it is coming from the nostrils or nasal passages, should be evaluated endoscopically.
