Equine 4th and 6th branchial arch defects are not uncommon in the equine population at large but can be challenging to diagnose and treat. An understanding of the anatomical structures that can be involved and how structural abnormalities may affect laryngeal function is important for clinicians faced with such cases. Diagnosis is often made using resting endoscopic examination alone but, in many cases, laryngeal ultrasound, radiography and 3-dimensional (3D) imaging techniques can be useful in confirming a diagnosis and for detecting which structures are abnormal. Exercising endoscopy is an important tool when ascertaining whether treatment is an option, for guiding treatment choice and making a prognosis for athletic function.

“…Das Phänomen der Rostralverlagerung des Arcus palatopharyngeus (RVAP) beim Pferd wurde mehrmals beschrieben (Cook 1974, Goulden et al 1976, Deegen und Klein 1987, Klein et al 1989, Garrett et al 2009). Grundlage ist eine Missbildung der Kehlkopfknorpel als Resultat einer fehlerhaften Entwicklung des vierten Kiemenbogens (fourth branchial arch defect, 4-BAD), (Goulden et al 1976, Klein et al 1989, Lane et al 2006a, Lane et al 2006b, Lane 2007, Garrett et al 2009).…”

Intermittent Rostral Displacement of the Palatopharyngeal Arch in a horse due to 4-BADA 4 year old Holsteiner mare was presented to the Clinic for Horses of the University of Veterinary Medicine in Hannover for complaints of a respiratory noise occurring during exercise. A rostral displacement of the palatopharyngeal arch was diagnosed by the referring veterinarian in the sedated horse. The horse was examined clinically. An intermittent, inspiratory noise was heard during exercise. During endoscopy as well as during radiography a rostral displacement of the palatopharyngeal arch could be diagnosed only in a sedated condition or immediately after antagonising a sedation. During ultrasonography laryngeal malformation was evident as an abnormal space between the cricoid and thyroid cartilage. The cricoarytenoideus lateralis muscle appeared to be in an abnormal location. The articulation between the cricoid and thyroid cartilage was not obvious. Based on our experiences with this case, resting upper airway endoscopy should be performed routinely in the sedated and unsedated horse. An ultrasonographic examination of the larynx can help to confirm the diagnosis of a laryngeal malformation. Based on this report, exercise endoscopy alone cannot replace resting endoscopy in the sedated horse in every case. The rostral displacement of the palatopharyngeal arch could be identified as the potential cause of the respiratory noise in this horse by exercise endoscopy because stridor occurred during the endoscopically visible displacement.
