Аннотация
BACKGROUND: Improvement of modern neurosurgical technology has given rise to keyhole surgery for a wide range of pathologies. Supraorbital trans-eyebrow approach has been described in detail for small tumors of anterior cranial fossa and suprasellar neoplasms. Can we use this small and less traumatic approach for a more complex tumor extending beyond the suprasellar region?
OBJECTIVE: To analyze own experience of surgical treatment of large and giant parasellar tumors via supraorbital approach, to identify the principles of such operations, indications and possible limitations.
MATERIAL AND METHODS: There were 58 resections of parasellar tumors via mini-supraorbital approach had been performed between 2016 and 2021 at the 2nd pediatric neurosurgical department. We selected 42 patients with large and giant tumors extending beyond the chiasmal-sellar zone and causing occlusive hydrocephalus (mean volume 44.2 cm3). Preoperative status of patients, postoperative clinical data and logistics of in-hospital treatment were analyzed.
RESULTS: Total resection was performed in all cases. No redo surgeries or revisions were required. There were no cases of wound infection, CSF leakage and damage to large vessels.
CONCLUSION: We standardized planning of surgeries for large neoplasms considering available knowledge about the nature of diseases, analysis of clinical and X-ray data, goals and objectives of surgery. The reader is offered a theoretical substantiation of applicability of keyhole surgery for chiasmal-sellar tumors on the example of well-known mini-supraorbital approach. We gave certain advices on planning such operations and illustrated clinical examples.
