To assess the morphology of nasopalatine canal and to determine the variation of this canal in correlations to age and gender in Iraqi sample using cone beam computed tomography (CBCT).
A total of 200 requested CBCT images for nasopalatine canal evaluation before dental implantology at the anterior maxillary region. The morphology of canals was classified into 3 groups in coronal cross-sections. The effects of age and gender were also measured.
The study comprised 100 males and 100 females with mean age of 30.64 ± 9.46 years. Most of the cases showed Y-shape configuration type III 43.5% followed by type I single canal 35.5%, and type II with 2 parallel canals 21%, CONCLUSION:: Due to the wide variation in the morphology of nasopalatine canals, it is highly recommended to perform CBCT evaluation to the anterior maxilla before dental implantology in order to prevent any damage to the neurovascular bundle.
使用锥形束计算机断层扫描（CBCT）评估伊拉克样本中鼻腭管的形态，并确定该管在年龄和性别方面的变异情况。
共收集了200例上颌前部区域牙种植术前用于评估鼻腭管的CBCT图像。在冠状面将管的形态分为3组。还测量了年龄和性别的影响。
该研究包括100名男性和100名女性，平均年龄为30.64±9.46岁。大多数病例显示为Y形构型III型（43.5%），其次是I型单管（35.5%），II型双平行管（21%）。结论：由于鼻腭管形态差异很大，强烈建议在牙种植术前对上颌前部进行CBCT评估，以防止对神经血管束造成任何损伤。
