Multiple anomlaies often lead to pansinusitis,of which maxi llary and ethmoid sinusitis were most frequently involved. 多種解剖變異並存時往往同時引起多竇腔炎症，受累最重的是上頜竇其次是篩竇。
Forobtaining the bets result,the height of maxillary-ethmoid and the height from the up-edgeof maxillary-ethmoid plate to the roof of posterior ethmoid were measured. 鼻前棘至后篩頂后緣的距離及角度，觀察中鼻甲的走行及附著，篩骨水平板的形態及后篩竇的分度及變異，為臨床手術提供了一定的解剖學依據。
There were statistical differences between the adult group and the pediatric group in ethmoid bulla hypertrophy and middle nasal concha etherealization. 篩泡肥大和中鼻甲氣化的出現率在成年組和未成年組差異有統計學意義。
