The provider accesses the anterior cranial fossa using a craniofacial approach to expose an extradural (outside the dura) lesion or defect at the skull base. Lateral rhinotomy, ethmoidectomy, and sphenoidectomy are included in this approach procedure, but other surgeries, repairs, or reconstructions should be reported separately. The selection of a particular approach will depend on the location and size of the lesion.
