J. Tetens et al., TRANSENDOSCOPIC CONTACT NEODYMIUM-YTTRIUM ALUMINUM GARNET LASER TREATMENT OF TYMPANY OF THE AUDITORY TUBE DIVERTICULUM IN 2 FOALS, Journal of the American Veterinary Medical Association, 204(12), 1994, pp. 1927-1929
Tympany of the auditory tube diverticulum was treated in 2 Standardbre
d foals by fenestrating the median septum, using an endoscopically pla
ced Nd:YAG laser. Recurrence in 1 foal was treated by enlarging the fe
nestration, using a modified Whitehouse approach, and the pharyngeal o
pening of the auditory tube. Use of the Nd: YAG laser eliminates the r
isk of inadvertent cranial nerve damage associated with incisions into
the auditory tube diverticulum. The procedure can be performed with t
he horse sedated or anesthetized. Clinical signs can recur in the fene
stration heals closed or if the condition is bilateral rather than uni
lateral.
