Thirty-one patients suffering from acute frontal sinusitis were treated by trephination. The patency of the nasofrontal duct was measured daily via the ventilation tube by computerized rhinomanometry until the tube was removed. According to the air flow changes inside the frontal sinus during normal nasal breathing, the duct was assessed as open, partially open or obstructed. The further healing process was assessed by clinical and radiological examination during a two-month postoperative follow-up. Statistical analysis of the results shows that both the favourable healing process and recurrences can be predicted with this method to a very high level of significance. The method is simple and rapid and it helps to determine the correct time for the withdrawal of the irrigation tube in individual patients.
31例急性额窦炎患者接受了环钻术治疗。通过通气导管，利用计算机化鼻阻力测量法每日测量鼻额管的通畅情况，直至导管移除。根据正常鼻呼吸时额窦内的气流变化，评估鼻额管为开放、部分开放或阻塞。在术后两个月的随访期间，通过临床和影像学检查评估进一步的愈合过程。结果的统计分析表明，用这种方法可以非常显著地预测良好的愈合过程和复发情况。该方法简单快速，有助于确定个别患者拔除冲洗管的正确时间。
