Pre-operative view (a), 3D-CT image (b), axial CT image (c). Prominent broad nose deformity was identified and shrinkage of maxillary sinus and prominent expansion of nasal cavity and piriform aperture can be seen.

Significant broad nose deformity was evident, and the computed tomography (CT) images (Figure 1) revealed a collapsed maxillary sinus and a prominent expansion of the nasal cavity and piriform aperture.
Osteotomy lines. Central V lines: medial-oblique osteotomies. Most outside lines: low-curved lateral osteotomies. Lines between them: multiple lateral osteotomies.

Due to this concern, we decided to use multiple lateral osteotomies on the nasal sidewall in addition to the low-curved lateral osteotomies and the medial-oblique osteotomies (Figure 2). The planned osteotomies are shown in Figure 2.
Post-operative view (a), 3D-CT image (b), axial CT image (c) at 1 year after the surgery. The post-operative nose was aesthetically excellent and shrinkage of maxillary sinus and prominent expansion of nasal cavity and piriform aperture were improved.
