探讨额窦、鼻额管及毗邻部位的解剖关系。方法：选国人成人干颅骨２５例５０侧，将颅骨矢状正中锯开，用直尺、游标卡尺、量角器等测量工具测量。结果：在５０侧标本中额窦未发育占１４％，额窦矢状径（ｘ±ＳＤ）为１２．９６±７．３３ｍｍ，额骨的内侧板和眶上壁骨质厚度分别为１．１５±０．７７和１．０６±０．５９ｍｍ，鼻额管长为８．４５±４．３２ｍｍ，鼻额管开口直径为５．２９±１．９ｍｍ，开口位置５０％于额隐窝，３０％于筛漏斗附近或筛漏斗内，４％于筛顶，２％在同侧上颌窦顶。额窦口距筛前动脉管为３．４±２．８３ｍｍ。结论：额窦于２岁后渐发育，也可终身不发育。国人额窦矢状径较西方人明显减少约４ｍｍ，为东方人比西方人较少合并额窦炎并发症的原因之一。额骨内侧板和眶上壁的骨质菲薄也为毗邻部位合并症发生的原因。鼻额管的狭长、开口的位置可导致额窦炎及并发症发生率的升高。筛前动脉于额窦口的后壁，此处可为术中标志。
Explore the frontal sinus, nasal tube and adjacent anatomy. Methods: Selected Chinese adult skull dry 25 cases of 50 sides, the skull was cut into the middle sagittal, using ruler, vernier caliper, protractor and other measuring tools to measure. Results: In 50 specimens, the frontal sinus was undeveloped by 14%, the frontal sinus sagittal (x ± SD) was 12.96 ± 7.33mm, and the thickness of the medial plate and supraorbital wall of frontal bone was 1.15 ± 0.77 and 1.06 ± 0.59mm, nasal tube length of 8.45 ± 4.32mm, nasal tube opening diameter of 5.29 ± 1.9mm, the location of the opening 50% of the amount of crypt, 30% In the sieve hopper near the sieve or hopper, 4% at the top of the screen, 2% at the ipsilateral maxillary sinus. The frontal sinus ostium is 3.4 ± 2.83 mm from the anterior ethmoid artery. Conclusion: Frontal sinus gradually developed after 2 years of age, but also can be undeveloped throughout life. The amount of sinus sagittal diameter of Chinese people was significantly reduced by about 4mm compared with Westerners, which is one of the reasons that Oriental people have less complications of frontal sinusitis than Western people. Frontal medial plate and supraorbital bone femoral congenital bone formation is also adjacent to the cause of complications. Nasal tube narrow, open position can lead to frontal sinusitis and complications increased. Anterior ethmoid artery in front of the posterior wall of the mouth, where signs can be intraoperative.
