B. Lussier et al., THE EFFECT OF UNILATERAL ARYTENOID LATERALIZATION ON RIMA GLOTTIDIS AREA IN CANINE CADAVER LARYNGES, Veterinary surgery, 25(2), 1996, pp. 121-126
Five modifications of a cricoarytenoid lateralization and two modifica
tions of a thyroarytenoid lateralization laryngoplasty technique were
evaluated for their effect on rima glottidis area. All procedures and
evaluations were performed on canine cadaver larynges. Cricoarytenoid
lateralization (GAL) techniques provided a greater increase of the siz
e of the glottic opening than did any of the thyroarytenoid lateraliza
tion techniques. Cricoarytenoid and interarytenoid disarticulation ass
ociated with CAL did not significantly increase glottic size compared
with normal. After disarticulation of the cricoarytenoid joint, there
was no difference in glottic enlargement whether the suture was placed
through the muscular process or through the articular facet of the ar
ytenoid cartilage. Transection of the sesamoid band combined with cric
oarytenoid diarticulation distorted the dorsal margin of the rima glot
tidis. (C) Copyright 1996 by The American College of Veterinary Surgeo
