The most common cause of laryngotracheal stenosis is trauma. The stenotic area may involve the larynx, subglottis, or trachea. A hyoid bone graft has been used in 22 cases for reconstruction of the stenotic area. The hyoid graft may be used with other concomitant laryngeal procedures. A vascularized sternohyoid--hyoid graft has been used in somes cases. Of the 22 cases all but 3 have been successful. The advantages of the hyoid graft are: 1. Firm graft to maintain the architecture of the lumen. 2. Accessibility in the same operating field. 3. Patient's own graft material decreases immune rejection possibility. 4. The vascularized pedicle graft decreases possibility of hyoid resorption.
喉气管狭窄最常见的原因是外伤。狭窄区域可能累及喉部、声门下或气管。已在22例病例中使用舌骨移植来重建狭窄区域。舌骨移植可与其他喉部联合手术一起使用。在一些病例中使用了带血管蒂的胸骨舌骨肌-舌骨移植。在这22例病例中，除3例以外均获成功。舌骨移植的优点有：1. 移植牢固，可维持管腔结构。2. 在同一手术视野中易于获取。3. 患者自身的移植材料可降低免疫排斥的可能性。4. 带血管蒂的移植可降低舌骨吸收的可能性。
