What Is Basilar Invagination?

Basilar invagination, also known as platybasia ("flat base") or craniovertebral junction anomaly, is a condition where the skull (specifically, the part called the occiput) is pushed into the spinal canal, compressing the brainstem and spinal cord. This can lead to a variety of symptoms, including headaches, neck pain, dizziness, difficulty swallowing, and problems with balance and coordination.

Basilar invagination can be congenital (present from birth) or acquired. Congenital basilar invagination is usually caused by a combination of factors, including abnormal development of the skull and spine, and defects in the ligaments and muscles that support the head and neck. Acquired basilar invagination can be caused by trauma, infection, or other conditions that damage the skull or spine.

Treatment for basilar invagination depends on the severity of the condition and the patient's symptoms. In some cases, surgery may be necessary to correct the deformity and relieve pressure on the brainstem and spinal cord. In other cases, non-surgical treatments such as physical therapy, bracing, or pain medication may be sufficient.

Basilar invagination is a serious condition, but it can be successfully managed with proper treatment. If you are experiencing any of the symptoms of basilar invagination, it is important to see your doctor for evaluation. Early diagnosis and treatment can help to prevent serious complications.
