The ventral-to-dorsal height of the rima glottidis was measured from lateral pharyngeal radiographs after correction for magnification. The rima glottidis height was used to enlarge accurately endoscopic photographs of 5 horses taken before and after transection of the left recurrent laryngeal nerve. Areas of the rima glottidis and aditus laryngis were measured, using a computerized digitizer. Mean area of the aditus laryngis was 1,908 mm2 before neurectomy and 1,346 mm2 after neurectomy (P = 0.025). Mean area of the rima glottidis was 1,198 mm2 before neurectomy and 805 mm2 after neurectomy (P = 0.025). Mean width of the rima glottidis was 31 mm before neurectomy and 20 mm after neurectomy (P = 0.001). Significant differences were not found between the pre- and postneurectomy heights of the rima glottidis.
在对放大率进行校正后，从咽侧位X线片测量声门裂的腹侧至背侧高度。声门裂高度用于精确放大5匹马在左侧喉返神经横断术前和术后拍摄的内镜照片。使用计算机数字化仪测量声门裂和喉口的面积。神经切除术前喉口的平均面积为1908平方毫米，神经切除术后为1346平方毫米（P = 0.025）。神经切除术前声门裂的平均面积为1198平方毫米，神经切除术后为805平方毫米（P = 0.025）。神经切除术前声门裂的平均宽度为31毫米，神经切除术后为20毫米（P = 0.001）。声门裂神经切除术前和术后的高度之间未发现显著差异。
