Lateral supraorbital approach in surgical treatment of pathological lesions of anterior cranial fossa and chiasmo-sellar region

Abstract

There are several different approaches for the surgical treatment of cranial base pathology in the region of anterior cranial fossa (ACF). Objective: to examine the features of lateral supraorbital approach (LSOA) and treatment outcomes while using such approach in patients with tumors and bone defects of ACF base. Material and methods: LSOA was used in 126 patients among them 102 patients had olfactory groove meningiomas, 16 persons - pituitary adenomas and craniopharyngiomas and 8 patients suffered from ACF bone defects with nasal liquorrhea. Results: The radical removal of tumors was achieved in 95% of patients with meningiomas and in 62,5% of patients with pituitary adenomas and craniopharyngiomas. The hemorrhagic complications requiring repeated surgery was observed in 2 (1,5%) patients. The plasty of ACF bone defects was performed in 23 (18%) patients. There were no signs of postoperative liquorrhea in any case. Conclusion: LSOA has several advantages in the surgery of ACF base pathology comparing with the other surgical approaches. The good outcomes concerning radicality of tumors removal as well as efficacy of ACF bone defects reconstruction were achieved with the low risk of postoperative complications.
