Interhemispheric supraorbital or frontopolar approach: anatomical study

A modification of the supraorbital approach is proposed in order to improve the access to the medial portions of the anterior and middle fossas (supraselar region). it consists of a midline extension of the frontal craniotomy along with an interhemispheric approach: interhemispheric supraorbital or frontopolar approach. The anatomical basis of this approach were studied in eight cadaveric heads. Its results demonstratete that this approach adequaly access the medial structures of the anterior and medial fossas with minimal brain retraction and wide exposure.
