Experimental study on repair of cricoid cartilage defect with cartilage grafts in rabbits

兔环状软骨损伤后软骨修复的实验研究

Objective : To study the ultrasound features of the cricoid cartilage .

目的：探讨环状软骨的正常超声所见。

For 62.5 % specimens , the inferior edge of cricoid cartilage board located the level of the sixth cervical vertebrae .

环状软骨板下缘有62.5%位于颈6椎体水平。

Results : Not only did inferior constrictor start from thyroid cartilage and cricoid cartilage , but also start from first trachea ring .

结果：发现咽下缩肌不仅有起于甲状软骨和环状软骨的肌纤维，而且有起于第1气管环的肌纤维和肌腱。

That hyoid bone covers the entrance of cricoid cartilage will bring constriction of the new laryngeal orifice and make decannulation difficult .

舌骨盖在环状软骨上口易造成新喉口狭窄引起拔管困难。

[ Conclusion ] Application of circular nickel titanium alloy stent in tracheostomy , which exerts a supporting effect of cricoid cartilage , can effectively prevent the tracheostomal stenosis after total laryngectomy .

【结论】环形镍钛合金支架在气管造口成形中起到了环状软骨样的支撑作用，有效地防止全喉切除术后气管造口狭窄的发生。

After anastomosis of cricoid cartilage and base of tongue ( epiglottis ), the epiglottis can exactly cover the entrance of cricoid cartilage to prevent aspiration fully and increase decannulation rate .

行环舌根（会厌）吻合术，会厌能准确盖在环状软骨上口，充分起到防止误咽的保护作用，并且提高了拔管率。

The movement of cricoid cartilage which turned around the coronal axis through bilateral cricothyroid joints could cause the extension and contraction of the bilateral vocal cords , with 3 . 41 mm range between the extention and contraction .
