Functional endoscopic sinus surgery is now the standard intervention for recalcitrant chronic paranasal rhinosinusitis. Computed tomography (CT) is the usual modality for preoperative investigation of the paranasal sinuses. Imaging provides information about anatomical variations in the area and may also give some information about disease severity. Dehiscence of the lamina papyracea, with herniation of the orbital contents into the ethmoid sinuses, can be a consequence of facial trauma or a nontraumatic anatomical variation. It may involve protrusion of orbital contents through an adjacent defect or a medial protrusion of the lamina papyracea itself.
