Algorithm for reconstruction of composite cranial defects using the fascial component of free anterolateral thigh flaps.

BACKGROUND

In case of composite cranial defect including the dura mater, the cranial bone, and the scalp, the fascial component of the anterolateral thigh flap can be used for dural reconstruction. However, the advantages and applications of the fascial component depending on the type of defect have not been thoroughly discussed. We made the algorithm for reconstruction of composite cranial defects using the fascial component of free anterolateral thigh flaps.

PATIENTS AND METHODS

Six cases of composite cranial defects were reconstructed using free anterolateral thigh flaps with the fascial component. The type of method used was classified into 3 types. Type 1 involves separating the fascia from the flap completely and using it as a nonvascularized component. In type 2, the fascia is not separated from the flap and is instead used as a vascularized component. Type 3 involves separating the vascularized adipofascial component from the skin paddle and using it as a chimeric pattern flap. The algorithm for determining the type of fascial component is applied depending on the condition of the defect.

RESULTS

All flaps were transferred successfully in every case. In 4 cases, the type 1 method was used. The type 2 and 3 methods were used in 1 case each. Cranial bone reconstruction was performed in 3 cases. There were no major complications after the procedures.

CONCLUSIONS

The fascial component is useful for dural reconstruction. The type of fascial component used is selected depending on the condition of the defect.
