Abstract
|
|
|
|
The nasoseptal flap (NSF) has been broadly used to reconstruct skull base defects as well as other head and neck site defects recently. Generally, NSF reconstruction may cover a defects successfully in many cases because of neurovascular pedicle that supplies necessary elements for flap to survive and re-establish. However, when NSF applied to cover the avascular surfaces such as osteoradionecrotic tissue which is induced by radiotherapy or artificial materials that used for bony structure reconstruction may lose an advantage and increasing possibility of flap failure. Therefore, we try to contemplate 2 cases of flap failure following application to avascular surfaces to prevent such a situations in future surgeries.
