We describe a surgical technique in which the middle fossa craniotomy ordinarily used for facial nerve decompression and related surgery is extended superiorly to allow the harvest of a split-thickness calvarial graft. This graft allows the tegmen defect in middle fossa surgery to be repaired without shortening the original craniotomy plate. Avoiding the usual temporoparietal depression after middle cranial fossa surgery is both a structural and cosmetic benefit for the patient.
