摘　　要：目的:利用锥形束CT(CBCT)了解鼻腭管的正常解剖形态并进行分类。方法:选取华西口腔医院放射科289例CBCT影像资料,对鼻腭管解剖形态进行分析。结果:CBCT矢状面图像中鼻腭管呈管型者最多见(103例,35.64%);水平面图像中,切牙孔无骨突型者最多(154例,53.29%),中段孔也是无骨突型者最多(138例47.75%),鼻腭孔骨突型者最多(160例,55.36%);冠状面分支为单管型者最常见(204例,70.59%)。结论:正常鼻腭管形态多种多样,利用CBCT对其进行详细而准确的术前分析,为前牙区手术提供重要信息,避免手术损伤鼻腭管。Objective： Cone-beam computed tomography （CBCT） was used to analyze and assess anatomical varia- tions and morphology features of nasopalatine canal. It provided valuable information for dental implant surgery of anterior maxilla regions, as well as diagnosis of nasopalatine canal cyst. Method： Two hundred and eighty-nine CBCT images were randomly selected from the database of the department of oral radiology, West China Hospital of Stomatology. All the CBCT images were carefully analyzed and classified. Result：The most prevalent type on sagittal images was cylindrical shape （103,35.64 %）：on axial images, none bony crest was the most prevalent among incisive foramen （154, 53.29 %） and middle foramen （138,47.75 % ）;bony crest （160,55.36 % ） was the most prevalent in nasopalatine foramina：single canal （204, 70.59%） was the most common in coronal images. Conclusion： Nasopalatine canal shows highly anatomical variations. A clearly analysis with CBCT before surgery in anterior maxilla region is helpful in providing necessary information for den- tal implant surgery. It helps doctors avoid damaging nerves and vessels in nasopalatine during the surgery.
