Abstract

The study objective is evaluate the effectiveness and risks of using intradural and extradural decompression of the optic nerve channels during standard transcranial removal of meningiomas of the chiasmal-cellar region region. Materials and methods. The results of 161 decompression of channel of optic nerve in 129 patients are analyzed. In most patients (n = 122), an intradural decompression (resection) of the canal roof was performed. In 7 patients, an extradural decompression of the upper and lateral walls of the canal was performed. Results. In assessing the risks of visual impairment as a result of channel decompression, we found that decompression itself, without attempts to separate the tumor from the nerve, causes vision impairment in 8.6 % of cases. Attempts to separate the tumor from the optic nerves increase the risk of vision impairment from 16.7 to 26.9 %, depending on the radicality. Conclusion. A small number of complications (iatrogenic amaurosis and nasal liquorrhea) make it possible to recommend the described technique as an effective and safe addition to standard transcranial operations to remove the meningiomas of the chiasmal-cellar region.
