The article discusses and analyzes the results of the treatment of 56 patients with tumors of the orbit, cranioorbital region, operated at the neurosurgery clinic DCTMA in Donetsk from 2015 to February 2020, with various surgical approaches. Goals and Objectives: Coverage of clinical signs and symptoms, histology, diagnostic methods and treatment of patients operated on with tumors of the orbit and cranioorbital region for the period 2015 2020. The rationale for the use of front-orbit-zygomatic access as the optimal surgical access to tumors of the orbit and cranioorbital region of various localization, to perform radical organpreserving surgery, with the maximum preservation of visual function, minimizing oculomotor disturbances, patient disability, good cosmetic effect in the postoperative period. Materials and Methods: We analyzed the clinical cases of 56 patients who underwent treatment in DCTMA with tumors of the orbit, cranioorbital region for the period from 2015 to March 2020. Patients were operated on with different approaches transcutaneous, subconjunctival, front-orbit-zygomatic, pterional, subfrontal. Surgical approaches were determined individually, depending on the location, size of the tumor, involvement in the process of the underlying structures of the orbit, adjacent anatomical areas (frontal, maxillary sinuses, cranial cavity, bones of the base of the skull). In 2 cases of lesions of the orbit by the tumor process a relapse of the tumor growth was obtained: one patient with aggressive adenocarcinoma, after 18 months, leading to orbital exenteration, and a 9-year-old child with rhabdomyosarcoma after non-radical removal of the tumor by subconjunctival approach. In all other cases, no relapses were noted; the operations were organ-preserving. Conclusion: The results of treatment of patients with orbital tumors directly depend on the radical removal of the neoplasm, which is associated with the choice of surgical approach, the use of chemo-, radiation therapy in the postoperative period, depending on the histological response.
