Retrobulbar tumors are orbital disease processes situated within vital tissue behind the eyeball and confined within the orbital space by the orbital bones. Surgery of the retrobulbar tumors is still difficult to perform, due to the complex anatomy of the orbit which can demand variations in surgical approach. In the case of orbital surgery, a surgeon will do his utmost to reach the apical area. One of the techniques well known in orbital surgery is lateral orbitotomy. This surgery is primarily aimed at removing zygomatic bone constituting the rim of the lateral orbital bone. The principle aim of lateral orbitotomy is to remove the tumor en toto by manipulating vital organs in the orbit as slightly as possible in order to avoid the complications of vision disorder. Thirty-one patients underwent lateral orbitotomy at the Dr. Cipto Mangunkusumo Hospital and other hospitals during the period between January 1985 to July 1982. The criteria for successful surgery consist of the evaluation of successful tumor removal with or without complications. Based on the success of the surgery and prognosis, the patients are divided into three groups, they are:1. Successful surgery, patient prognosis favorable, 2.Successful surgery, patient prognosis dubious and 3. Unsuccessful surgery, patient prognosis unfavorable. However, lateral orbitotomy did not result in complications in several types of tumors although they were located in the apical. This situation shows that even tumors in the apical area do not always affect the success of the lateral orbitotomy, and the failure of the surgery tends to be attributed more to tumor type.
