Xeroradiographic evaluation of the equine larynx.
Abstract: The normal radiographic anatomy of the equine larynx was determine by use of xeroradiography and dissection. The body and laminae of the thyroid cartilage, the muscular process of the arytenoid cartilages, and the dorsal lamina and arch of the cricoid cartilage had radiographic evidence of mineralization (calcification) and/or ossification in clinically normal horses. There was a significant (P less than 0.01) increase in the degree of mineralization of the thyroid and arytenoid cartilages with advancing age. Horses with diagnosis of arytenoid chondrosis (arytenoid chondral dysplasia, arytenoid chondropathy) by use of endoscopy had radiographic changes that included: enlargement with increased density of the arytenoid cartilage region, abnormal patterns of mineralization (dystrophic mineralization or osseous metaplasia), abnormal contour of the corniculate process(es) and laryngeal masses, sometimes obliterating part or all of the lateral laryngeal ventricles.

This research article presents a study investigating the normal xeroradiographic anatomy of the horse larynx, determining that certain parts of the larynx become mineralized with advancing age. Additionally, horses diagnosed with arytenoid chondrosis displayed various radiographic changes.
Overview
The study aimed to establish the normal radiographic anatomy of the horse larynx using xeroradiography and dissection. The investigation also explored the changes occurring in the larynx with the progression of age and in horses diagnosed with arytenoid chondrosis.
Methods and Findings
- This study involved the use of xeroradiography, a type of X-ray imaging technique, and dissection to determine the laryngeal structures in horses.
- The researchers found that certain parts of the equine larynx including the body and laminae of the thyroid cartilage, the muscular process of the arytenoid cartilages, and the dorsal lamina and arch of the cricoid cartilage displayed radiographic evidence of mineralization or calcification and/or ossification in clinically normal horses.
- The degree of mineralization of the thyroid and arytenoid cartilages showed a significant increase with the horse’s advancing age.
Arytenoid Chondrosis
- Horses diagnosed with arytenoid chondrosis (also known as arytenoid chondral dysplasia or arytenoid chondropathy) exhibited notable radiographic changes.
- These changes included an enlarged and denser arytenoid cartilage region, abnormal patterns of mineralization (dystrophic mineralization or osseous metaplasia), an abnormal contour of the corniculate process(es), and the formation of laryngeal masses which could sometimes obliterate part or all of the lateral laryngeal ventricles.
Significance
- This study elucidates the normative radiographic anatomy of the equine larynx and the changes that occur in relation to age or pathological conditions such as arytenoid chondrosis.
- Such knowledge could contribute to a more accurate diagnosis and improved treatment of laryngeal diseases in horses.
