CT-guided biopsy and tissue analysis
Minimally invasive needle biopsy of the abnormal odontoid tissue to obtain histological diagnosis and rule out neoplastic or inflammatory pathology requiring specific treatment.
Targeted medical therapy based on pathology
Disease-specific pharmacological treatment which may include bisphosphonates for bone abnormalities, immunosuppressants for inflammatory conditions, or antimicrobial therapy if infection is identified.
Additional treatment options
Destruction curettage or resection
Surgical removal of abnormal tissue with curettage or en-bloc resection depending on pathology extent. May be combined with stabilization procedures if structural integrity is compromised.
surgicalRegular neurological and radiographic monitoring
Periodic neurological examinations combined with advanced imaging to detect any progression of tissue abnormality or development of spinal cord compromise.
monitoringPost-treatment rehabilitation program
Comprehensive rehabilitation focusing on cervical range of motion restoration, strengthening, and functional mobility after medical or surgical treatment of the tissue abnormality.
