Laser fenestration of the dorsal pharyngeal recess does not correct experimentally induced dorsal nasopharyngeal collapse in horses.

ABSTRACT:

Objective

To quantify the impact of experimentally induced dorsal nasopharyngeal collapse (NPC) on respiratory performance parameters and assess the efficacy of laser fenestration of the dorsal pharyngeal recess as a treatment option for experimentally induced NPC.

Study design

Experimental interventional study.

Animals

Six adult Standardbreds (one with naturally occurring disease).

Methods

After an 8 week conditioning program, baseline parameters (V̇O₂max, pharyngeal pressure, peak airflows, upper airway resistance) and dynamic endoscopy videos were collected in a high-speed treadmill test (T1). Dorsal NPC was induced via bilateral glossopharyngeal neurectomy, followed by data collection 2 weeks later (T2). Laser fenestration of the dorsal pharyngea
