Abstract

To explore the significance of MR and endoscopy in the postoperative management of skull base reconstruction with a vascular pedicle nasoseptal mucoperiosteal flap. The immediate, and delayed postoperative MR imaging scans and endoscopic data of 8 patients who underwent endonasal endoscopic reconstruction of skull base dural defects with a vascular pedicle nasoseptal mucoperiosteal flap were retrospectively studied. Among the 8 patients, 7 cases have integrated immediate, delayed postoperative MR and synchronous endoscopic data which were harvest at the first week and at a 3- to 7-month interval respectively. One case was followed up by CT and endoscopy. The intracranial parenchymal changes, local situation of skull base defect site, the septal flap, healing of flap donor site and the transition of naso sinus mucosa were fully evaluated to explore the healing process and to improve the success rate of the reconstruction. We can obtain the key postoperative information of intracranial and the skull base reconstruction site with MR and endoscopy. The MR can exclude the intracranial complications such as postoperative intracranial hematoma, cerebral edema, or pneumocephalus, and clearly show the location and extent of skull base d...Continue Reading
