[Endoscopic management and outcome of nasosinusitis in non-traumatic dehiscence of the lamina papyracea with orbital content herniation].

To analyze the CT manifestations, clinical features, and endoscopic management and outcome of nasosinusitis in non-traumatic dehiscence of the lamina papyracea with herniation of orbital contents. From January 2019 to October 2020, a total of 686 cases with chronic nasosinusitis or nasal septum deviation were admitted to our department, including 448 male cases and 238 female cases. No patient had prior maxillofacial or orbital trauma as well as surgery related to nose and eyes. The clinical data were retrospectively analyzed. Twelve patients were diagnosed as dehiscence of the lamina papyracea. Preoperative CT revealed that the location of dehiscence was only in the ethmoid sinus. For nasosinusitis patients with non-traumatic dehiscence of the lamina papyracea, all ethmoid cells should be opened during FESS. Precise and skillful operation, good bleeding control and clear visual field were critical. no damage to the herniated periorbital fat during the operation and appropriate cavity packing after the operation are essential, which could avoid the orbital-related complications as well as improve the symptom resolution. No recurrence was found during the follow-up period.
