Abstract：
A 86-year-old male patient, diagnosed with lymphoma, was scheduled for a submaxillectomy to choose his best chemotherapy treatment. He referred recent voice changes and laterocervical adenopathies without respiratory symptoms. There were no additional risk predictors in preoperative airway assessment. Following anaesthesic induction, an upper airway obstruction occurred. After that, an unexpected difficult airway was encountered. Both clinical situations resulted in unpredicted difficult airway management. Image tests seen after the procedure revealed a severe narrowing of parapharyngeal space due to Waldeyer\'s ring hypertrophy. This medical condition had remained unnoticed in preoperative assessment. Advanced lymphoproliferative syndromes cause disseminated adenopathies whose parapharyngeal involvement can lead to a difficult airway even in the absence of preoperative risk predictors.
摘要：
一名86岁的男性患者,确诊为淋巴瘤,计划进行上颌下切除术以选择他最好的化学疗法。他提到了最近的声音变化和宫颈侧腺病，没有呼吸道症状。术前气道评估中没有其他风险预测因子。麻醉诱导后，发生上呼吸道阻塞。之后,遇到了意想不到的困难气道。两种临床情况都导致无法预测的困难气道管理。手术后的图像测试显示，由于Waldeyer的环肥大，咽旁间隙严重狭窄。这种医疗状况在术前评估中仍未被注意到。晚期淋巴增生综合征引起播散性腺病，即使在没有术前风险预测因子的情况下，咽旁受累也可能导致气道困难。
