[Reconstruction of anterior skull base defect by pedicle frontal muscle compound flap].

Objective: To evaluate the effect of one stage reconstruction for anterior skull base defect by pedicled frontal muscle compound flap after craniofacial combined approach operation.

Methods: Twelve patients with frontal skull base tumor and fracture (rudimentary cancer 5, malignant melanoma 1, neurogliocytoma 1, ethmoid sinus rhabdomyosarcoma 1, malignant papilloma 1, osteofibroma 2, underwent surgery 1) were included. The compound flap with pedicled frontal muscle galea aponeuroses pericranium was adopted which brought single blood vessel or double, and splinter skull bone. The compound flaps covered 8 cm -12 cm x 10 cm -15 cm.

Results: All 12 patients were successfully treated with no complication during follow-up from 1 to 48 months.

Conclusion: The compound flaps with pedicled frontal muscle galea aponeuroses pericranium, had ample blood supply and thin pliable and strong tissue which was a good reconstruction material for frontal skull base defect.
