Table 1 Failure cases to obtain proper pericranial flap
Case number | Length of flap (cm) | Additional incision | Reason of failure |
|---|---|---|---|
1 | 5.5 | No | Short flap (Technical limitation arisen from no additional incision on the scalp) |
2 | 5.9 | No | Short flap (Technical limitation arisen from no additional incision on the scalp) |
3 | 6.1 | No | Short flap (Technical limitation arisen from no additional incision on the scalp) The location of supraorbital notch was too lateral |
4 | 5.8 | No | Short flap (Technical limitation arisen from no additional incision on the scalp) Supraorbital nerve injury (Retraction injury) |
5 | 11.1 | Yes | Skin was too thin (In the process of dissection, the skin penetration and flap disconnection was happened. Therefore, we could not attain the flap through periosteal dissection) |
