CT images were obtained from the parents and reviewed. CT images showed a narrowed pyriform aperture measuring 5.4 mm (Figure 1).
CT image (pre-stenting): coronal view showing central mega-incisor (white arrow).

Mild medial angulation of the nasal processes of the maxilla was noted, and a single central mega-incisor was also noted (Figures 2 and 3).

Mild medial angulation of the nasal processes of the maxilla was noted, and a single central mega-incisor was also noted (Figures 2 and 3).
CT image (post-stenting): axial view of the widened pyriform aperture (star) measuring 10.3 mm. Nasal septum was partly eroded (white arrow).

These CT images showed a pyriform aperture measurement of 10.3 mm (considered satisfactory; Figure 4).
CT image (post-stenting): coronal view of the eroded septum (white arrow) and the central mega-incisor (black arrow).

The nasal septum was almost completely eroded, which was probably attributed to compression erosion by the stents (Figures 5 and 6).
