A greater incidence of nasal sinus lesions is revealed in patients operated for laryngectomy than in healthy subjects. The radiographs of the paranasal sinuses of 49 patients laryngectomized for laryngeal cancer and 71 smokers, over 40, were compared. Thirty-six (73.5%) of the operated patients showed a reduction in the lucency of the sinuses (opacities, sinusitis, mucocele) and 21 (42.9%) inferior concha hypertrophy. In the control group 23 (32.4%) and 12 (16.9%) cases had the same lesions. Chi2 statistical analysis was performed on both groups. The results show a significant increase in lesions of the nasal sinuses in the group of operated patients. The reduction in the air flow through the nose and the sinus cavities during breathing seems to be the pathogenic mechanism responsible for such findings.
接受喉切除术的患者鼻窦病变的发生率高于健康受试者。对49例因喉癌接受喉切除术的患者和71名40岁以上吸烟者的鼻窦X光片进行了比较。36例（73.5%）接受手术的患者鼻窦透明度降低（混浊、鼻窦炎、黏液囊肿），21例（42.9%）下鼻甲肥大。在对照组中，23例（32.4%）和12例（16.9%）有相同病变。对两组进行了卡方统计分析。结果显示，接受手术的患者组鼻窦病变显著增加。呼吸时通过鼻腔和鼻窦腔的气流减少似乎是导致这些结果的致病机制。
