We believe that, with the modified Kronlein lateral orbitotomy microsurgical approach, most orbital tumors can be successfully removed with reduced morbidity and complications, compared with the frontotemporal craniotomy or the standard Kr6nlein lateral orbitotomy. The cosmetic result is quite satisfactory, and the hospital stay should be brief. The use of the operating microscope and the specifically designed and modified instruments for retraction and dissection in the orbit, combined with the efficiency of the self-irrigating bipolar coagulating forceps, add a new dimension to the safety and efficiency of orbital surgery.
