The maxillary ostial function, measured as pressure transmission capacity, ostial airway resistance, equivalent ostial diameter during nasal breathing and with a constant artificial air-flow of 16.7 cm3 X S-1 into the sinus, was compared in three groups of patients. One group consisted of 7 sinuses in 6 patients with maxillary pain but without any signs of sinusitis; a second group of 6 sinuses in 6 patients with intramaxillary cysts; and a third group of 6 sinuses in 5 patients with chronic maxillary sinusitis. No impairment of the ostial function was found in groups one and two. In the third group an increased airway resistance of the ostia and small equivalent ostial diameters were found in both sitting and recumbent positions. With the pressure recording technique, the ostium can be judged as patent, non-patent, or partially obstructed, but no further grading can be done. With the pressure-flow technique the ostial function can be evaluated as ostial resistance or equivalent ostial diameters under 'physiological conditions' when the ostium is patent. With a constant artificial air-flow into the sinus the equivalent ostial diameter can be estimated even in non-patent ostia but the equivalent ostial diameters obtained do not always reflect the true functional state of the ostium.
对三组患者的上颌窦口功能进行了比较，该功能通过压力传递能力、窦口气道阻力、鼻呼吸时的等效窦口直径以及在向窦内恒定输入16.7 cm³×s⁻¹的人工气流情况下进行测量。第一组包括6例有上颌疼痛但无任何鼻窦炎体征患者的7个鼻窦；第二组包括6例有上颌囊肿患者的6个鼻窦；第三组包括5例慢性上颌窦炎患者的6个鼻窦。在第一组和第二组中未发现窦口功能受损。在第三组中，无论是坐位还是卧位，均发现窦口气道阻力增加且等效窦口直径较小。使用压力记录技术时，窦口可被判断为通畅、不通畅或部分阻塞，但无法进一步分级。使用压力-流量技术时，当窦口通畅时，窦口功能可在“生理条件”下评估为窦口阻力或等效窦口直径。在向窦内恒定输入人工气流的情况下，即使是不通畅的窦口也可估计等效窦口直径，但所获得的等效窦口直径并不总是反映窦口的真实功能状态。
