Fifteen subjects underwent nasal pressure gradient studies to determine the resistance profile of the nose. Seventy-nine per cent of nasal resistance to airflow occurred in the segment 0 cm.-2.8 cm. from the posterior margin of the anterior nares. The greater part of this resistance (43 per cent) occurred in the segment 1.5 cm.-2.8 cm. within the nose, and this area approximated to the site of the pyriform aperture. Eighteen patients underwent a trial of radical trimming of the inferior turbinates (12 patients) versus anterior trimming of the inferior turbinates (6 patients). Both operations produced a similar fall in nasal resistance to airflow, confirming that the region of the pyriform aperture was the site of maximum nasal resistance. Whereas the radical operation significantly reduced the sensation of nasal obstruction, the anterior operation did not. The results of the study are discussed with reference to previous work on the subject.
15名受试者接受了鼻压力梯度研究，以确定鼻子的阻力分布情况。79%的鼻气流阻力出现在距前鼻孔后缘0厘米至2.8厘米的节段。这种阻力的大部分（43%）出现在鼻内1.5厘米至2.8厘米的节段，该区域接近梨状孔的位置。18名患者接受了下鼻甲根治性修剪试验（12名患者）与下鼻甲前部修剪试验（6名患者）。两种手术均使鼻气流阻力出现类似下降，证实梨状孔区域是鼻阻力最大的部位。根治性手术显著减轻了鼻塞感，而前部手术则没有。该研究结果结合此前关于该主题的研究进行了讨论。
