结合文献资料作者对15个颅底进行了死后解剖的研究。年龄从新生儿至75岁。对12个前颅凹、筛板、每个气窦(除上颌窦外)作了解剖及放射线摄影。另3个筛窦区、乳突小房、鼓室腔作了连续组织切片的观察。其结果认为:前颅凹的筛板在三岁时已经完全骨化,但非常薄,其厚度在某些部位不到100微米。颅底骨折时很容易导致颅鼻瘘。额窦在3岁以后才逐渐明显,4岁以前对前颅凹手术不发生关系,至少在大多数病人中直至年龄较大儿的
Combined with literature data on 15 cranial base after the anatomy of the study. Age from newborn to 75 years old. Anatomy and radiography were performed on 12 anterior cranial fossa, sieve plate, and each sinoadenoma (except maxillary sinus). The other three ethmoid sinus, mastoid cells, tympanic cavity for continuous tissue section observation. The result is that the anterior disc-shaped sieve is completely ossified at the age of three, but very thin, with a thickness of less than 100 microns in some areas. Skull fracture can easily lead to cranial fistula. The frontal sinus gradually becomes apparent after 3 years of age and does not have a relationship with anterior cranial recess before age 4, at least in most patients up to older children
