Surgical Strategy for Retro-Odontoid Pseudotumor Treatment

Abstract

  The pathophysiology of retro-odontoid pseudotumors (ROP) varies, and in some cases, the instability between the atlantoaxial vertebrae is unclear, making it difficult to select a surgical method. Lesions gradually shrink and disappear after posterior cervical fusion. Direct lesion resection is necessary if neurological symptoms are imminent. The surgical method must be carefully selected, taking into account the symptoms and patient background, and long-term follow-up must be conducted.
