[目的:探讨双侧裂开对环状软骨生长发育的影响。方法:将幼兔环状软骨前、前后及前后加双侧裂开,8个月后测量环状软骨内径,计算其管腔面积。结果:①与对照组比较,实验组兔环状软骨管腔面积差异无统计学意义(P>0 .05) ;②裂开处均由软组织连接,未形成过多瘢痕。结论:双侧裂开对环状软骨及幼兔的生长发育无显著影响。
[Objective] To investigate the influence of bilateral dehiscence on the growth and development of cricoid cartilage. Methods: Rabbits were anterior, anteroposterior and anterior and posterior plus split the rabbits, and the diameter of the annular cartilage was measured 8 months later, and the lumen area was calculated. Results: ① Compared with the control group, there was no significant difference in the annular area of the annular cartilage in the experimental group (P> 0.05); ② The cleft was connected by the soft tissue without excessive scar formation. Conclusion: Bilateral cleavage has no significant effect on the growth and development of cricoid and young rabbits.
