【摘要】：目的:了解下頜管的解剖位置和變異尤為重要,CBCT能為下頜種植手術(shù)和下頜磨牙拔除術(shù)以及下頜骨矢狀劈開(kāi)術(shù)提供理論參考和臨床指導(dǎo)。利用CBCT初步探討維吾爾族成年人下頜神經(jīng)管分支的發(fā)生率及分型。方法:收集2014-2016年在新疆醫(yī)科大學(xué)第一附屬醫(yī)院口腔科就診病人214例,征得患者同意登記個(gè)人信息并拍攝CBCT。利用CBCT評(píng)估這214名維吾爾族患者的下頜管及其有無(wú)分支。左右兩側(cè)研究了(n=428).在矢狀位、冠狀位、橫斷位及三維全景位對(duì)圖像進(jìn)行必要重建和評(píng)估。觀察患者有無(wú)下頜管分支,描述分支變異情況及其走向并進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:214例(428側(cè))維吾爾族患者,51例(23.8%)觀察到下頜管分支,其中女31例(14.48%),男20例(9.34%),發(fā)現(xiàn)下頜管雙分支1例,最為常見(jiàn)的下頜管分支為前行管(第Ⅲ類(lèi)),發(fā)生率為8.88%,其次是磨牙管(第Ⅰ類(lèi)),發(fā)生率為8.41%和牙管(第Ⅱ類(lèi)),發(fā)生率為4.67%,最后是頰舌管(第Ⅳ類(lèi)),發(fā)生率為1.87%。結(jié)論:利用CBCT不但能夠清晰觀察下頜神經(jīng)管的三維影像,而且能夠精確地顯示下頜神經(jīng)管的位置和走行,這將大大降低并發(fā)癥的發(fā)生。通過(guò)CBCT能夠很好地觀察下頜管有無(wú)分支這一解剖結(jié)構(gòu)。本文通過(guò)回顧性分析214例維吾爾族成年人下頜神經(jīng)管CBCT,發(fā)現(xiàn)維吾爾族成年人下頜神經(jīng)管分支發(fā)生率與其它種族比較較低,但與國(guó)內(nèi)研究報(bào)導(dǎo)基本一致。對(duì)選擇合適的治療方案有臨床實(shí)用價(jià)值。
[Abstract]:Objective: to understand the anatomical position and variation of mandibular canal. CBCT can provide theoretical reference and clinical guidance for mandibular implantation, mandibular molar extraction and sagittal split mandibular surgery. The incidence and classification of mandibular canal branches in Uygur adults were studied by CBCT. Methods: from 2014 to 2016, 214 patients were enrolled in the Department of Stomatology, the first affiliated Hospital of Xinjiang Medical University. They registered their personal information with the consent of the patients and photographed CBCT.. The mandibular canal and its branches were evaluated by CBCT in these 214 Uygur patients. The left and right sides were studied (n 鈮，
