Comparison of two techniques for transpharyngeal endoscopic auditory tube diverticulotomy in the horse.
Abstract: Auditory tube diverticula, also known as guttural pouches, are naturally occurring dilations of the auditory tube in horses that communicate with the nasopharynx through a small ostium. Infection and select other conditions can result in inflammation and narrowing of the nasopharyngeal ostium, which prevents drainage of fluid or egress of air and can lead to persistent infection or guttural pouch tympany. Auditory tube diverticulotomy allows continuous egress from the auditory tube diverticula and is a feature of disease treatment in horses, in which medical treatment alone is not successful. Transpharyngeal endoscopic auditory tube diverticulotomy was performed using a diode laser either at a single dorsal pharyngeal recess location or bilaterally caudal to the nasopharyngeal ostium in 10 horse head specimens. Both methods resulted in clear communication between the nasopharynx and auditory tube diverticula. Diverticulotomy performed in the dorsal pharyngeal recess required less laser energy and activation time and had a shorter surgical duration than diverticulotomy performed caudal to the nasopharyngeal ostium. Further study related to the clinical application of both techniques is warranted.

This research article examines and compares the effects of two methods for performing transpharyngeal endoscopic auditory tube diverticulotomy in horses, a treatment procedure for persistent infection or guttural pouch tympany.
Transpharyngeal Endoscopic Auditory Tube Diverticulotomy
- Transpharyngeal endoscopic auditory tube diverticulotomy is a surgical procedure that involves opening narrow or blocked areas in the auditory tube diverticula in horses using an endoscope.
- The primary goal of this procedure is to promote continuous drainage of fluids or airflow from the auditory tube diverticula, which is essential for treating conditions such as persistent infection or guttural pouch tympany.
Comparison of Two Techniques
- The study compared diverticulotomy performed at a single dorsal pharyngeal recess location versus diverticulotomy performed bilaterally caudal to the nasopharyngeal ostium. Both these techniques were administered using a diode laser on ten horse head specimens.
- Both methods were successful in reestablishing clear communication between the nasopharynx and the auditory tube diverticula. The open communication, in turn, enables free flow of air or fluids within this area, eliminating conditions like tympany or persistent infection.
Results of the Study
- Although both techniques were effective, the diverticulotomy performed at the dorsal pharyngeal recess showed potential benefits over the one performed caudal to the nasopharyngeal ostium. This technique required less laser energy and activation time, and significantly reduced the overall duration of the surgery, effectively making it more efficient.
- Despite these findings, the researchers state that more investigation is needed to understand the clinical implications of both techniques fully. Future studies should explore both techniques’ efficacy, safety, and feasibility in a clinical setting.
