Cadaveric cartilage was cut into blocks with a newly devised cartilage cutter. Over one-hundred pieces of cartilage were used to define a kinetics curve of cartilage warping. Kinetics curves were developed for a control group of cartilage blocks placed in saline-soaked gauze (n = 46). In addition, kinetics curves were developed for cartilage placed in hypotonic saline (n = 14), hypertonic saline (n = 14), and cyanoacrylate glue (n = 6). Photographs of all groups were taken at timed intervals in order to plot the cartilage warping. It was found that pieces of cartilage which were cut peripherally (n = 6) warped twice as much as those cut centrally (n = 40). This was significant to p = 0.001. Within 15 minutes, centrally cut pieces of cartilage warped to approximately 90 percent of their end warpage; on the other hand, peripherally cut pieces of cartilage required 30 minutes to warp 90 percent of their destined warpage. The variables used did not significantly alter the kinetics curves as compared with control.
用一种新设计的软骨切割器将尸体软骨切成块。使用了一百多块软骨来确定软骨翘曲的动力学曲线。为放置在浸有生理盐水的纱布中的软骨块对照组（n = 46）绘制了动力学曲线。此外，还为放置在低渗盐水（n = 14）、高渗盐水（n = 14）和氰基丙烯酸酯胶（n = 6）中的软骨绘制了动力学曲线。在规定的时间间隔拍摄所有组的照片，以便绘制软骨翘曲情况。发现周边切割的软骨块（n = 6）的翘曲程度是中央切割的软骨块（n = 40）的两倍。这在统计学上具有显著性，p = 0.001。在15分钟内，中央切割的软骨块翘曲至其最终翘曲度的约90%；另一方面，周边切割的软骨块需要30分钟才能翘曲至其预定翘曲度的90%。与对照组相比，所使用的变量并未显著改变动力学曲线。
