【摘要】： 目的:利用高速螺旋CT三維重建額隱窩,了解額隱窩應(yīng)用解剖,為鼻內(nèi)鏡額竇開(kāi)放術(shù)提供術(shù)前參考。方法:利用TOSHIBA 16排高速螺旋CT對(duì)51例臨床資料進(jìn)行額隱窩的三維重建,用VITRA 2軟件觀察額隱窩毗鄰結(jié)構(gòu)。結(jié)果:CT三維重建均可辨認(rèn)出額竇、額竇內(nèi)口及額隱窩。結(jié)論:額隱窩的形態(tài)個(gè)人差異很大,取決于其與毗鄰結(jié)構(gòu)的解剖關(guān)系,其中以鼻丘氣房和鉤突的作用為大。鼻丘氣房可做為額竇手術(shù)開(kāi)放額隱窩的解剖標(biāo)志。內(nèi)鏡手術(shù)時(shí),以前鼻棘為起點(diǎn),與鼻底平面成央角50—60。、半徑100mm左右的扇形區(qū)域?yàn)槭中g(shù)的相對(duì)安全界。術(shù)前CT三維重建額隱窩對(duì)制定手術(shù)計(jì)劃有重要指導(dǎo)意義。
[Abstract]:Objective: to reconstruct the forehead recess with high speed spiral CT and to understand the applied anatomy of the forehead recess, so as to provide preoperative reference for endoscopic frontalis surgery. Methods: TOSHIBA 16 row high speed spiral CT was used to reconstruct the forehead recess in 51 cases. The adjacent structure of the forehead recess was observed by VITRA 2 software. Results: three-dimensional reconstruction of CT could identify the frontal sinus, the internal orifice of the frontalis sinus and the recess of the forehead. Conclusion: the morphology of the forehead recess is very different, which depends on the anatomical relationship between it and the adjacent structure, in which the nasal colliculus and uncinate process play an important role. The nasal colliculus chamber can be used as an anatomical marker for the opening of forehead recess in forehead sinus surgery. In endoscopic surgery, the former nasal spine was used as the starting point, and the central angle with the nasal floor plane was 50 鈮，
