Abstract
Introduction. Each of the pathologies is rare and can lead to compression of the brainstem and spinal cord, with the development of a “mixed” clinical picture. The tactics of treating such patients differs from one author to another.The objective is to present the author’s experience in treating patients with basilar invagination associated with type I Chiari malformation and to analyze the literature on the methods of surgical treatment of this pathology.Materials and methods. From 2014 to 2019, 3 patients with a basilar invagination and type I Chiari malformation were surgically treated at the N. I. Pirogov National Medical and Surgical Center. Indications for surgical intervention were long-term progressive neurological disorders, lack of effect from conservative therapy. Patients underwent anterior transnasal and posterior decompression of nerve structures followed by stabilization.Results. All patients were evaluated 12 months after surgery. All patients in neurological status showed positive dynamics. According to magnetic resonance imaging of the craniovertebral junction, 2 patients showed positive dynamics: regression of the myelopathy, a decrease in the diameter of the syringomyelic cyst.Conclusion. The criteria for anterior transnasal decompression are the predominance of bulbar disorders and / or paresis in the extremities in the clinical picture; posterior decompression of nerve structures, indicated in the presence of specific symptoms of type I Chiari malformation and / or syringomyelia. Taking into account the results of the latest published studies it can be assumed that stabilization is a necessary option in the treatment of patients with this pathology.

Summary
Результаты хирургического лечения пациентов с базилярной инвагинацией, ассоциированной с аномалией Киари I типа. Цель публикации – обобщить собственный опыт лечения пациентов с базилярной инвагинацией, ассоциированной с аномалией Киари I типа, и сопоставить результаты с данными научной литературы. Пирогова было проведено хирургическое лечение 3 пациентов с сочетанием базилярной инвагинации и аномалии Киари I типа. Выполнена передняя эндоскопическая трансназальная и задняя декомпрессия нервных структур с последующей стабилизацией. Передняя эндоскопическая трансназальная декомпрессия нервных структур показана при преобладании в клинической картине бульбарных нарушений и / или парезов конечностей, задняя декомпрессия – при наличии специфических симптомов аномалии Киари I типа и / или сирингомиелии. Принимая во внимание результаты последних исследований, можно предположить, что стабилизация является необходимой составляющей лечения пациентов с данными патологиями. А.
