Computed Tomography in the Diagnosis and Planning of Surgical Intervention in Vestibular Schwannomas

The role of computed tomography (CT) in the diagnosis and surgical planning of vestibular schwannomas (also known as acoustic neuromas). To analyze the specific application of CT for identifying tumor size, location, and characteristics, as well as assessing their relationships with surrounding structures, including the bony components of the skull and the inner ear. The study presents modern approaches to utilizing CT for optimizing surgical planning and improving the effectiveness of procedures. This approach aims to reduce the risks of complications and enhance patient outcomes. The article analyzes data from studies conducted at the Clinical Base of the Department of Neurosurgery at Kyrgyz State Medical Academy, neurosurgical departments of the Osh Region, and the National Hospital of the Ministry of Health of the Kyrgyz Republic. Between 2013 and 2023, 120 patients diagnosed with vestibular schwannomas were examined and operated on using the retrosigmoid suboccipital approach. Considering all direct and indirect signs on CT images, approximately 41% of schwannomas remain undetected with standard (non-contrast) scans. Conclusion: The obtained data confirm the importance and effectiveness of using CT as a standard method during the preoperative preparation for vestibular schwannoma treatment. This promotes the integration of modern diagnostic technologies into clinical practice.
