Long-term follow-up results of dural reconstruction without bone graft at anterior skull-base defects.
To clarify whether it is necessary to reconstruct bone defects at the anterior skull base. ⋯ At normal intracranial pressure, if the dura mater is repaired properly at the skull-base defects and reinforced with a pedicled pericranial flap, encephalomeningocele and cerebrospinal fluid (CSF) leakage can be prevented. It may not be necessary to make free bone grafts when the size of the cranial base bone defect is smaller than 4 cm.
