Free rectus abdominis muscle flap reconstruction of the middle and posterior cranial base.
A multidisciplinary approach by the neurosurgeon, ENT surgeon, and plastic surgeon has been used in seven patients with extensive tumors involving the middle and posterior skull base. Wide resection of these tumors was accomplished, and the resultant defect of the cranial base was reconstructed using free rectus abdominis muscle flaps. The free muscle flap has been used to reconstruct defects in the posterior and lateral walls of the nasopharynx, obliterate the exposed paranasal sinuses, and cover tenuous dural repairs or dural grafts overlying the temporal lobe and posterior fossa to prevent cerebrospinal fluid leakage and ascending meningitis.
