Optimal tension, position, and number of prostheses required for maximum rima glottidis area after laryngoplasty


Bischofberger, Andrea S; Wereszka, Marta; Hadidane, Ines; Perkins, Nigel R; Jeffcott, Leo; Dart, Andrew J (2013). Optimal tension, position, and number of prostheses required for maximum rima glottidis area after laryngoplasty. Veterinary Surgery, 42(3):280-285.

Abstract

OBJECTIVES: To evaluate the effect of 3 laryngeal prostheses alone or in combination on rima glottidis area in horses.
STUDY DESIGN: Experimental randomized design.
SAMPLE POPULATION: Cadaveric equine larynges (n = 22).
METHODS: Three prostheses were preplaced in each of 14 larynges. Rima glottidis area was measured after loading each suture in 5 Newton (N) increments from 0 N to 35 N. In 8 larynges, the 3 prostheses were tied alone or in combination at a fixed load of 15 N and rima glottidis area measured.
RESULTS: Rima glottidis cross-sectional area increased as the load on each prosthesis increased with maximum area reached at 20 N for each prosthesis. At a fixed load of 15 N, tying 2 and 3 prostheses in combination resulted in a larger rima glottidis cross-sectional area than achieved with each prosthesis alone.
CONCLUSIONS: A combination of 2 or 3 prostheses tied at a fixed load of 15 N optimized rima glottidis cross-sectional area irrespective of the anatomic location of the prosthesis.
