Concha bullosa is generally regarded as pneumatisation of the middle turbinate in the nose. However, pneumatisation may also be seen in the superior and inferior turbinate. Computed tomography (CT) of paranasal sinuses is extremely helpful for the examination of this inaccessible area. Coronal CT sections of paranasal sinuses are particularly useful for surgical anatomy, as these images show nearly the same regions as the endoscopic examinations. The aim of this retrospective study was to evaluate the presence, incidence and unilaterality-bilaterality of superior turbinate pneumatisation and concomitant nasal pathologies.
