Basilar impression

چکیده
Basilar impression is a skeletal malformation characterized by translocation of the upper cervical spine and clivus into the foramen magnum, giving rise to various symptoms related to brainstem, upper spinal cord, and cerebellar compression. It is generally classified as primary (familial), in which the defect is unaccompanied by intrinsic abnormalities of bone, or as secondary, reflecting an intrinsic bone defect, as is the case in osteogenesis imperfecta. In this article, the author provides a review on basilar impression, with a discussion of additional experiences on surgical management.
