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.
评估了环杓侧移术的五种改良方法和甲杓侧移术喉成形术的两种改良方法对声门裂面积的影响。所有手术和评估均在犬类尸体喉部进行。与任何甲杓侧移术相比，环杓侧移术（CAL）能使声门开口尺寸增加得更多。与CAL相关的环杓关节和杓间关节离断与正常情况相比，并未显著增加声门尺寸。环杓关节离断后，无论缝线是穿过杓状软骨的肌突还是关节面，声门扩大情况均无差异。籽骨带横断联合环杓关节离断会使声门裂的背侧边缘变形。
