Hemifacial dismasking flap for anterior skull base tumor--technical note.

A new approach to malignant tumor in the anterior skull base using a hemifacial dismasking flap is described. A bicoronal incision is extended unilaterally down to the neck, degloving the craniofacial tissue to widely expose the skeleton underneath, allowing easy resection of an extensive tumor without postoperative scarring of the face. This method has been used successfully on five patients.
