Abstract:
SUMMARY The normal radiographic anatomy of the equine larynx was determined 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 < 0.01) increase in the degree of mineralization of the thyroid and arytenoid cartilages with advancing age.

Abstract:
A review of our recent experience in patients with bilateral laryngeal paralysis is described. While we continue to use phrenic nerve transfers in patients with mobile arytenoids, patients with fixed arytenoids generally require some sort of vocal cord lateralization, either by arytenoidectomy and arytenoidopexy or by partial vocal cord resection. The endoscopic laser medial arytenoidectomy is a convenient and effective method for opening the posterior glottic airway. One arytenoid is reduced medially with the carbon dioxide laser. After about 3 months the opposite arytenoid can be treated sim

Objective To evaluate laryngeal function by means of videoendoscopy during high-speed treadmill exercise in racehorses with grade-III left laryngeal hemiparesis at rest and to determine outcome of treatment. Design Retrospective study. Animals 26 racehorses. Procedure Videoendoscopy of the larynx was performed while horses were at rest and exercising on a treadmill. Horses were classified as having grade-III A, -IIIB, or -IIIC laryngeal hemiparesis on the basis of the degree of arytenoid cartilage abduction maintained during exercise.

AbstractWe report the clinical course of blunt laryngeal trauma in three young patients. All three patients underwent several phoniatric examinations as well as indirect microlaryngoscopy and microstroboscopy. The follow-up period ranged from three to eight months. In the first case, there was isolated haemorrhage of the left vocal fold; in the second, dislocation of the arytenoid cartilage with formation of an adhesion in the area of the anterior commissure; and, in the third, non-dislocated fracture of the thyroid cartilage with development of haematoma in the right hemilarynx and transient

Abstract:
Arytenoid subluxation (AS), ie, malpositioning of the arytenoid cartilage with abnormal but existent contact between the joint surfaces, is an uncommon entity, and fewer than 70 cases have been reported, 26 of which were in a recently published series. Usually, AS is the result of upper airway instrumentation, and only a few cases were reported to occur with external trauma to the neck. Some predisposing factors and possible mechanisms have been suggested, but the reason for its occurrence remains obscure. Hoarseness and, to a lesser degree, dysphagia, odynophagia, cough, and sore throat may b

Abstract:
Chondroma of the laryngeal cartilage is a rare, benign neoplasm which can manifest as a neck mass or, if situated within the airway, as slowly progressive obstruction, hoarseness or dyspnea. The most common location for chondroma is the posterior lamina of the cricoid cartilage; the next most common locations are the thyroid, arytenoid and epiglottic cartilages. Chondroma and low-grade chondrosarcoma are difficult to distinguish from one another histologically. Although chondrosarcoma reportedly recurs, local surgical excision without radical margins and with long-term clinical follow-up is re

Eighty-eight percent of the horses were either Thoroughbred (54 horses; 72%) or Standardbred (12 horses; 16%) racehorses; only 9 horses (12%) had occupations not related to racing.
