【摘要】：目的通過(guò)多層螺旋CT對(duì)41例青少年鼻竇進(jìn)行掃描,使用三維重建軟件將額隱窩區(qū)域氣房進(jìn)行冠狀位與矢狀位重建,研究青少年額隱窩區(qū)域的三維CT影像解剖學(xué)特征,探尋青少年額竇炎發(fā)病與額隱窩解剖結(jié)構(gòu)變異之間的關(guān)系。 方法收集41例(82側(cè))2010年1月-2011年11月于本院耳鼻喉科住院的14-18歲青少年,男性24例,女性17例,平均年齡(15.97±1.49)歲,依據(jù)其是否患額竇炎分為正常組25例(47側(cè)),其中3側(cè)額竇未發(fā)育,患病組16例(32側(cè))。采用16層螺旋CT掃描,層距0.7mm,層厚1mm,獲得軸位CT影像學(xué)資料后再使用Simplant14.01軟件對(duì)其進(jìn)行冠狀位及矢狀位三維重建。將重建的冠狀位、矢狀位結(jié)合軸位CT影像,觀察額隱窩區(qū)域各氣房分布、鉤突上端附著情況及測(cè)量額竇口徑線。 結(jié)果患病組Ⅰ-Ⅱ型額氣房出現(xiàn)率為56.25%,鼻丘氣房出現(xiàn)率為84.38%,眶上篩房的出現(xiàn)率為0%,篩泡上氣房出現(xiàn)率為40.63%,額竇中隔氣房的出現(xiàn)率為9.38%,終末隱窩出現(xiàn)率為18.75%,額泡氣房出現(xiàn)率為0%；正常組Ⅰ-Ⅱ型額氣房出現(xiàn)率為53.19%,鼻丘氣房出現(xiàn)率為74.47%,篩泡上氣房出現(xiàn)率為38.30%,眶上篩房出現(xiàn)率為6.38%,額竇中隔氣房出現(xiàn)率為6.38%,額泡氣房出現(xiàn)率為2.38%,終末隱窩出現(xiàn)率為14.89%,患病組與正常組額隱窩區(qū)域各氣房的出現(xiàn)率差異無(wú)明顯統(tǒng)計(jì)學(xué)意義；鉤突上端附著率正常組鉤突附著于眶紙板65.96%,中鼻甲23.40%,顱底10.64%；患病組鉤突附著于眶紙板75.00%,中鼻甲15.63%,顱底9.38%,患病組與正常組間鉤突上端附著率無(wú)明顯統(tǒng)計(jì)學(xué)意義；除右側(cè)額竇口前后徑差異無(wú)統(tǒng)計(jì)學(xué)意義外,其余額竇口各徑線的差異均有統(tǒng)計(jì)學(xué)意義。 結(jié)論初步推斷青少年額隱窩區(qū)域氣房尚未發(fā)展到成人穩(wěn)定階段,額隱窩氣房并不是青少年額竇炎發(fā)病的主要致病因素；提示額竇口的狹窄,尤其是實(shí)驗(yàn)結(jié)果顯示雙側(cè)額竇口左右徑的狹窄可能是造成青少年額竇引流通道狹窄,引流不暢,進(jìn)而引起額竇炎的致病因素；通過(guò)Simplant軟件重建冠狀位和矢狀位CT有助于青少年額隱窩氣房的一一辨認(rèn),從而使術(shù)者在掌握復(fù)雜的額隱窩區(qū)域解劑的基礎(chǔ)上制寂完整精確的手術(shù)方案。
[Abstract]:Objective to study the anatomical features of frontal recess in 41 cases of juvenile paranasal sinuses by multi-slice spiral CT scanning, and to reconstruct the frontal recess area with coronal and sagittal position using three-dimensional reconstruction software. To explore the relationship between frontal sinusitis and anatomic structure variation of frontal recess in adolescents. Methods from January 2010 to November 2011, 41 cases (82 sides) aged 14 to 18 years (male 24, female 17, mean age 15.97 鹵1.49) were collected. According to whether or not the patients suffered from frontal sinusitis, they were divided into 25 cases (47 sides) in normal group, 3 sides of which had no development of frontal sinus and 16 cases (32 sides) of frontal sinusitis. 16-slice spiral CT scan was used. The axial CT imaging data were obtained and then reconstructed by Simplant14.01 software in coronal and sagittal position. The reconstructed coronal and sagittal CT images were combined with axial CT images to observe the distribution of gas chambers in the frontal recess region. The attachment of the upper end of the uncinate process and the measurement of the frontal sinus caliber. Results in group 鈪，
