Thyroid cartilage fractures due to external blunt trauma have typically been thought to occur in patients over the age of 40. Lack of mineralization of the cartilage has been considered to be the protective mechanism. Our experience with laryngeal injuries has demonstrated that younger persons are indeed at risk for thyroid cartilage fractures, and that these injuries may be easily overlooked. Although these fractures do not lead to laryngeal stenosis if untreated, they may cause noticeable phonatory changes. Fixation of these fractures is difficult because of the usual soft character of the unmineralized cartilage, prompting us to adopt a wire-tube fixation technique. This technique has been uniformly successful in restoring the anatomic contour of the thyroid cartilage, and our results appear to justify open reduction of these moderately displaced or angulated thyroid cartilage fractures.
因外部钝性创伤导致的甲状软骨骨折通常被认为发生在40岁以上的患者中。软骨矿化不足被认为是一种保护机制。我们在喉部损伤方面的经验表明,年轻人确实有发生甲状软骨骨折的风险,而且这些损伤可能很容易被忽视。虽然这些骨折未经治疗不会导致喉狭窄,但可能会引起明显的发声变化。由于未矿化软骨通常质地柔软,这些骨折的固定很困难,促使我们采用钢丝管固定技术。该技术在恢复甲状软骨的解剖轮廓方面一直很成功,我们的结果似乎证明对这些中度移位或成角的甲状软骨骨折进行切开复位是合理的。
