A new pressure flow method for function tests and calculation of the airway resistance in the naso-frontal duct is presented. With this pressure flow technique the function and airway resistance of the naso-frontal duct was tested in 49 patients who were trephined for acute frontal sinusitis. The tests were performed during the primary healing period (0-16 days) and in a long term study 2, 6 and 12 months after operation. The patients were also checked radiologically and clinically. A prolonged healing period (more than 6 days) corresponded significantly to a high incidence of recurrent disease. With this method it is possible to define groups where recurrences might be expected because of impaired function of the naso-frontal duct.
本文介绍了一种用于鼻额管功能测试和气道阻力计算的新压力流方法。采用这种压力流技术，对49例因急性额窦炎行环钻术的患者的鼻额管功能和气道阻力进行了测试。测试在一期愈合期（0 - 16天）进行，并在一项长期研究中于术后2、6和12个月进行。还对患者进行了放射学和临床检查。愈合期延长（超过6天）与疾病复发的高发生率显著相关。通过这种方法，可以确定由于鼻额管功能受损可能预期会复发的患者组。
