This systematic review showed that dural sealants did not reduce the number of CSF leaks in general, the number of incisional CSF leaks alone, or the number of pseudomeningocele formations alone. However, dural sealants reduced the risk of surgical-site infection.

The skull base tumor model is an effective tool to provide more practice in preoperative planning and technical skills.

Given the high cost of sealants and the results of this study, we advocate a critical attitude toward sealant application as an adjunct to classic dural closure.

This study suggests MVD as a valid treatment for medically refractory INN. MVD carries surgical risk, but given the severity of complaints of these patients, we believe the treatment benefits outweigh the associated complications.
