The carbon dioxide laser has proved valuable in treating patients with severe scarring of the pharynx and supraglottic larynx. There is minimal re-scarring, and an open operation may be avoided. In conjunction with an open procedure, the laser provides a good method of controlling granulation tissue. Two cases of complete pharyngeal stenosis, resulting from caustic ingestion, are described. In one case, repair was achieved by supraglottic laryngectomy and gastro-hypopharyngeal transposition which temporarily obscured the larynx completely. The laser was used to re-open the laryngeal airway, following which the patient had normal eating, breathing and speaking.
二氧化碳激光已被证明在治疗咽部和喉上区严重瘢痕形成的患者中具有重要价值。再次瘢痕形成极少，且可避免开放性手术。与开放性手术相结合，激光提供了一种控制肉芽组织的良好方法。本文描述了两例因吞服腐蚀性物质导致完全性咽狭窄的病例。其中一例通过喉上切除术和胃-下咽转位术进行修复，该手术暂时完全遮盖了喉部。随后使用激光重新开通喉气道，之后患者恢复了正常的进食、呼吸和说话功能。
