在60个尸头(男34,女26)上观察与测量了经上颌窦筛窦手术时有关的形态结构。眶下孔至眶下缘的距离平均6.8±3.4mm;眶下孔至梨状孔缘距离13.1±4.1mm;筛上颌板长9.1±3.0mm;宽5.4±1.5mm;筛上颌板上缘至后筛板顶的高度为 22. 3±3. 7 mm。筛顶板内缘与筛板间的高度差为 0～4 mm者有 59侧(占 49.2％);4～7mm者有 52侧(占43. 3％);7 mm以上者有9侧(占7.5％)。
Morphological structures related to maxillary sinus ethmoid sinus surgery were observed and measured on 60 cadaver heads (male 34, female 26). The distance from the infraorbital foramen to the infraorbital margin was 6.8 ± 3.4mm on average; the distance from the infraorbital foramen to the piriform rim was 13.1 ± 4.1mm; the maxillary maxillary plate was 9.1 ± 3.0mm long and 5.4 ± 1.5mm wide; The height of the top deck is 22.3 ± 3. 7 mm. There were 59 sides (49.2%) in the height difference between the inner edge of the sieve top plate and the sieve plate. There were 52 sides (43.3%) in 4 ~ 7mm, 9 sides (7% 7.5%).
