Nasal airflow resistance was measured in order to study physiological changes in the upper airway before and after adenoidectomy. The posterior method was better for measuring the state of the posterior portion of the nasal cavity, as compared with the anterior method. The posterior method was modified by improving the pressure piece, the size of which had been inadequate for insertion into a child's mouth. A positive correlation was found between the adenoidal-nasopharyngeal ratio examined on X-ray film and the nasal airflow resistance both before and after surgery. Also there was a positive correlation between the weight of the resected adenoids and nasal airflow resistance preoperatively. Nasal airflow resistance was found to be significantly higher in patients who snored, breathed by mouth or had nocturnal breathing disorders than in those without these symptoms.
为研究腺样体切除术前、后上气道的生理变化，测量了鼻气流阻力。与前法相比，后法更适合测量鼻腔后部的状态。通过改进压力片对后法进行了改良，压力片原来的尺寸对于插入儿童口腔来说过小。在术前和术后，X线片上检测到的腺样体-鼻咽比值与鼻气流阻力之间均呈正相关。此外，术前切除的腺样体重量与鼻气流阻力之间也呈正相关。发现打鼾、口呼吸或有夜间呼吸障碍的患者的鼻气流阻力显著高于无这些症状的患者。
