RESULTS OF SURGICAL TREATMENT OF CRANIOORBITAL BRAIN TUMOR

Abstract

The problem of surgical treatment of neoplasms located in the cranio-orbital region 
and orbital cavity has long attracted the attention of researchers. The complexity of removing 
such neoplasms consists of both the dense arrangement of neurovascular and muscular structures 
in a small volume of the orbit, and the possible spread of the tumor into the adjacent cavities of 
the paranasal sinuses and the cranial cavity. A possible solution is to develop adequate surgical 
approaches. Historically, the development of surgery for neoplasms of the cranio-orbital region 
and orbit occurred in accordance with 2 approaches: extracranial and intracranial. In 1874, H. 
Knapp [Cited by 4], using the conjunctival superior orbitotomy developed by him, removed a 
retrobulbar tumor, preserving the eyeball, and in 1889 R. U. Kronlein proposed resecting the 
lateral wall of the orbit to remove a tumor of the muscular funnel [Cited by 4]. In 1922, the 
American neurosurgeon WEDandy was the first to remove a tumor from the orbit using a 
transcranial intradural approach, performing an osteoplastic trepanation of its upper wall from a 
subfrontal approach [6,7]. In Russia, the first work devoted to transcranial surgery of orbital 
tumors was an article by A.G. Zhagrin [2], which proposed improving the classic WEDandy 
approach by using an extradural approach to the orbital roof. In subsequent years, modifications 
to the transcranial approach concerned only the nature of the trepanation window.
