Use of intralesional formalin administration for treatment of a subepiglottic cyst in a horse.
METHODS
A 4-year-old horse was evaluated for chronic coughing, mucopurulent nasal discharge, and failure to thrive.


RESULTS
Endoscopy was performed on the larynx, pharynx, and trachea and revealed an approximately 2-cm fluctuant subepiglottic cyst.


RESULTS
The subepiglottic cyst was treated with intralesional formalin administration. Following 2 injections, 2 weeks apart, the cyst was completely resolved with no evidence of scarring or epiglottic deformity.


CONCLUSIONS
Findings suggest that intralesional formalin administration for treatment of subepiglottic cysts may be a minimally invasive, economically suitable alternative to surgical treatments.
