Plain-English summary
This study looked at different surgical techniques to see how they affect the size of the opening in the throat of dogs, specifically focusing on the area called the rima glottidis. Researchers tested five variations of one technique and two variations of another technique on dog larynxes that had been preserved after death. They found that one technique, called cricoarytenoid lateralization, was better at increasing the size of this throat opening compared to the other techniques. However, some specific combinations of procedures did not lead to any significant improvement in size compared to normal. Overall, the findings suggest that while some surgical methods can help, not all modifications are effective in enlarging the glottic opening.
Abstract
Five modifications of a cricoarytenoid lateralization and two modifications 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 (CAL) techniques provided a greater increase of the size of the glottic opening than did any of the thyroarytenoid lateralization techniques. Cricoarytenoid and interarytenoid disarticulation associated 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 arytenoid cartilage. Transection of the sesamoid band combined with cricoarytenoid diarticulation distorted the dorsal margin of the rima glottidis.
