case_images: A diagnosis of periapical cyst in relation to the right upper anterior teeth (11 and 21) was diagnosed based on intraoral radiographs [Figure 1].

case_images: In the coronal section, there was an evidence of enlarged NPC between 11 and 21 with increased oral opening of NPC [Figure 2a]. In the axial section, the size of the NPC was enlarged in anteroposterior and mediolateral directions and it measured 7.65 mm x 6.47 mm [Figure 2b]. In the sagittal section, the shape of the nasopalatine canal was spindle shaped [Figure 2c].

case_images: The distance between the posterior wall of NPC and the palatal cortex was observed at palatal, middle, and nasal levels [Figure 3a]. The volume of NPC was measured as 1.267 cm3 in the sagittal section with the help of specialized Romexis software [Figure 3b]. A reconstructed 3D image of CBCT showed the variation of the presence of an enlarged nasopalatine canal in 11 and 21 regions [Figure 3c].
