下咽部狭窄是喉全切除术后比较常见的合并症。本文对1976年至1982年中的112例喉癌手术做了回顾性研究。其内容包括:癌的侵犯部位、瘘的发生率、放射治疗及喉全切除术后重建方法,从而提出造成下咽部狭窄的可能因素。作者指出,98%的下咽部狭窄发生在术后一年内,而不是癌的复发。下咽部狭窄依据病人主诉吞咽困难、吞服钡剂明确狭窄部位、及需扩张维持吞咽功能作出诊断。分析结果表明,下咽部狭窄的发生和部位与术腔重建方法有关。对放射治疗和瘘的形成未做更多的研究,似乎与下咽部狭窄的关系不大。从资料中得知发生下咽部狭窄的百分率:声门癌术后有20%,声门上癌术后有31%,而梨状窝 Hypopharyngeal stenosis is a common complication after total laryngectomy. This article retrospectively studied 112 cases of laryngeal cancer from 1976 to 1982. Its contents include: cancer invasion sites, the incidence of hemorrhoids, radiation therapy, and reconstruction methods after total laryngectomy, suggesting possible causes of hypopharynx stenosis. The authors pointed out that 98% of hypopharyngeal stenosis occurred within one year after surgery, rather than the recurrence of cancer. Hypopharyngeal stenosis is diagnosed on the basis of the patient’s complaint of difficulty in swallowing, the clear stenosis of the swallow, and the need to dilate to maintain swallowing function. The analysis showed that the occurrence and location of hypopharyngeal stenosis was related to the reconstruction method of the surgical cavity. No more research has been done on the formation of radiation therapy and sputum, which seems to have little to do with hypopharyngeal stenosis. The data showed that the percentage of hypopharynx stenosis occurred: 20% after glottic cancer surgery, 31% after supraglottic cancer surgery, and pear-shaped fossa
