Dysphagia secondary to partial pharyngeal stenosis after total laryngectomy is most likely attributable to the size of the reconstructed lumen. To reduce the incidence of this postoperative complication, we have utilized a modification of total laryngectomy that conserves the hypopharyngeal mucous membrane. The results of this surgical procedure are now reported in the context of two similar, contemporaneous groups of patients who underwent either standard wide-field laryngectomy or hypopharyngeal mucosa conservation laryngectomy. Statistical analysis showed no difference between groups in cancer control (P = .80) or survival (P = .65); whereas the group treated with hypopharyngeal conservation laryngectomy had significantly less pharyngeal stenosis as measured by dysphagia and need for dilatation (P = .011).
全喉切除术后继发于部分下咽狭窄的吞咽困难很可能归因于重建管腔的大小。为降低这种术后并发症的发生率,我们采用了一种保留下咽黏膜的全喉切除术改良方法。现将该手术方法的结果在两组相似的同期患者中进行报告,这两组患者分别接受了标准的广域喉切除术或下咽黏膜保留喉切除术。统计分析显示,两组在癌症控制方面(P = 0.80)或生存率方面(P = 0.65)无差异;然而,通过吞咽困难和扩张需求来衡量,接受下咽保留喉切除术治疗的组下咽狭窄明显更少(P = 0.011)。
