Natural dehiscence of the lamina papyracea is usually found in ostiomeatal unit CT images and during functional endoscopic sinus surgery. The surgery should be performed on the basis of clinical findings and ostiomeatal unit CT scans to determine the extent of disease and the structural anomalies. Preoperative awareness of dehiscence in the lamina papyracea is essential for avoiding orbital complications during surgery. Sinusitis arising from the natural dehiscence of the lamina papyracea is extremely rare. We report, with a review of the literature, a case of sinusitis due to the natural dehiscence of the lamina papyracea in a 46-year-old female, treated by endoscopic sinus surgery. The CT finding presented a huge natural dehiscence of the lamina papyracea and chronic sinusitis of the maxillary ethmoid sinus. Most of the patient's symptoms resolved without recurrence after endoscopic sinus surgery.
