There were statistical differences between the adult group and the pediatric group in ethmoid bulla hypertrophy and middle nasal concha etherealization. 筛泡肥大和中鼻甲气化的出现率在成年组和未成年组差异有统计学意义。
Performation of surgical procedures anterior to ethmoid bulla can avoid risks of the other models, therefore, endoscopic frontal sinusotomy in the route anterior to ethmoid bulla is a safe model. 结论通过鼻内镜对额窦开口及周围解剖结构的观察,认为星状裂作为恒定的解剖标志是识别额窦开口的关键区域。筛泡前径路是鼻内镜下额窦开放的安全入路,能避免其他径路存在的某些风险。
The ethmoid bone (/ˈɛθmɔɪd/; from Greek ethmos, "sieve") is an unpaired bone in the skull that separates the nasal cavity from the brain. It is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that make up the orbit of the eye.
