Submucosal cordectomy, an old procedure first described for the treatment of bilateral abductor vocal cord paralysis, was used to relieve glottic or minimal subglottic stenosis in four patients. Three attained adequate airways with no further procedures; one required subsequent dilations for granulation tissue after which decannulation was successfully effected. Although airway restoration has been successful, the resultant voice has been poor, poorer than that usually achieved with arytenoidectomy. When cricoarytenoid scarring precludes arytenoidectomy and lateral vocal cord fixation, an adequate laryngeal lumen can be restored with submucosal cordectomy if sufficient laryngeal cartilage support remains.
黏膜下声带切除术是一种最初用于治疗双侧声带外展麻痹的古老手术，现用于缓解4例患者的声门或轻微声门下狭窄。3例患者气道通畅，无需进一步手术；1例患者术后因肉芽组织增生需要后续扩张，之后成功拔管。虽然气道恢复成功，但术后嗓音不佳，比通常行杓状软骨切除术的效果更差。当环杓关节瘢痕形成妨碍行杓状软骨切除术和声带外侧固定术时，如果仍有足够的喉软骨支撑，黏膜下声带切除术可恢复足够的喉腔。
