Osteoplastic supraorbital orbitotomy in operations of retrobulbar tumours minimizes the necessity of retraction of frontal lobe by change of the direction of the surgical approach. The method allows also reconstruction of the orbital roof preventing postoperative pulsating exophthalmos. The results were supported by comparison of the late control CT scans performed in patients operated by the classical transcranial approach with the examinations performed in patients operated on by the described method.
