体位引流是诊断慢性化脓性上颌窦炎的方法之一。由于解剖上的原因上颌窦是副鼻窦引流最差、发病最多的鼻窦。上颌窦开口在窦腔最高处,且窦口小,与窦腔相比甚为悬殊,加上开口在中鼻道中后方,受额窦炎、筛窦炎流下脓液及牙病影响,所以上颌窦炎的发病率最高。当低头位引流时,窦口由高变低,窦底由低变高,故窦内分泌物易引流出。根据上述道理,我们在1,720名男性青年体检中应用“低头位引流法”诊断慢性化脓性上颌窦炎,方法如下:1.令可疑鼻窦炎者先擤出鼻腔之分泌物;2.以1%盐酸麻黄素液喷雾鼻腔或用1%麻黄素棉片塞入鼻腔,10分钟后取出,使中鼻道粘膜收缩,窦口开大;
Body position drainage is one of the methods to diagnose chronic suppurative maxillary sinusitis. Due to anatomical reasons maxillary sinus paranasal sinus drainage is the worst, most incidence of sinus. Maxillary sinus openings in the highest point of the sinus cavity, and the small ostia, compared with the sinus cavity is very poor, coupled with the opening in the middle of the nasal passages in the rear, affected by frontal sinusitis, ethmoid sinusitis pus and dental disease, so the maxilla The highest incidence of sinusitis. When the bow head drainage, the sinus ostia from high to low, sinus floor from low to high, it is easy to drain sinus secretions. Based on the above, we applied “bowhead drainage method” to diagnose chronic suppurative maxillary sinusitis in 1,720 young men’s physical examinations. The method is as follows: 1. Make nasal constriction of suspicious sinusitis first; Ephedrine hydrochloride spray nasal or ephedrine 1% cotton stuffed into the nasal cavity, 10 minutes after the removal of the mucosa in the nasal constriction, large ostium;
