Abstract:
Laryngeal disorders are relatively common in the horse, and thorough diagnostic evaluation is essential to make an accurate definitive diagnosis and selection of appropriate treatment. The value of exercising endoscopy must not be overlooked, and the recent development of dynamic (overground) endoscopy is providing new insights into dynamic laryngeal lesions. The focus of this article will be on recently described disorders and treatments or modifications to existing treatments. It summarizes the numerous investigations attempting to perfect the laryngoplasty procedure for treatment of laryngeal hemiplegia. The newly described conditions, bilateral dynamic laryngeal collapse, and dynamically flaccid epiglottis will also be discussed.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
Trachea
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
