Eight stenoses and 3 atresias of the larynx were treated by laminotomy after Réthi. The commonest indication was a perichondritis stenosis of the cricoid after prolonged intubation. Stenosis of the cricoid followed subactue laryngitis in two cases. The arytenoids were also ankylosed in 5 cases requiring a further procedure to widen the glottis. The operation may also be used as an additional procedure in selected cases of supraglottic and glottic stenosis. The operation has also proved useful in stenoses and atresias of the laryngo-tracheal junction area. Nearly all cases require an obturator keel for 3-6 months. This is removed endoscopically in cases of closed treatment, while a plastic closure of the laryngotracheal lumen is necessary after open operations. The respiratory function was restored satisfactorily in all but one patient, who developed perichondritis of the thyroid cartilage. The quality of the voice depends on the mobility of the vocal process of the arytenoids.
8例喉狭窄和3例喉闭锁采用雷蒂（Réthi）术后的椎板切除术进行治疗。最常见的指征是长时间插管后环状软骨的软骨膜炎性狭窄。2例环状软骨狭窄继发于亚急性喉炎。5例杓状软骨也发生了关节强直，需要进一步手术来扩大声门。该手术也可作为声门上和声门狭窄特定病例的附加手术。该手术在喉气管交界区狭窄和闭锁的治疗中也已证明是有用的。几乎所有病例都需要使用闭孔假龙骨3至6个月。在闭合治疗的病例中，通过内镜取出假龙骨，而在开放手术后则需要对喉气管腔进行整形闭合。除1例发生甲状软骨软骨膜炎的患者外，所有患者的呼吸功能均得到满意恢复。声音质量取决于杓状软骨声带突的活动度。
