Background and purpose

The fronto-temporo-orbito-zygomatic approach (FTOZA) is an alternative to the pterional approach in surgical resection of meningiomas of the medial part of the lesser wing of the sphenoid bone. The purpose of this study is to present our results of treatment of these meningiomas using the FTOZA.

Material and methods

Thirty patients (19 women, 11 men) with a central skull base tumour were included in the study. The neurological status of the patients was assessed before and after surgery as well as at the conclusion of treatment. The approximate volume of the operated tumour, its relation to large blood vessels, cranial nerves and brainstem, as well as consistency and vascularisation were assessed.


The symptom duration ranged from 1 to 36 months (median: 6 months). Impaired visual acuity was the predominant symptom in 27.5% of patients. Less frequent symptoms included paresis/paralysis of the third cranial nerve, headache, psychoorganic syndrome and epilepsy. Approximate volume of the tumours ranged from 5 to 212 mL (median: 63 mL). Total or subtotal resection was achieved in 77% of patients. The postoperative performance status improved in 16.5%, did not change in 52.8% and deteriorated in 26.4% of patients. One (3.3%) patient died after the surgery.


The FTOZA is a useful technique for removal of tumours expanding superiorly to the middle cranial fossa base without significant compression of the brain. Ability to remove tumours through the described approach decreases as the degree of infiltration of the clivus increases.
