Platybasia
Platybasia
Platybasia (pronounced: plat-ee-bay-zee-uh) is a medical condition characterized by the flattening or abnormal angulation of the base of the skull.
Etymology
The term "Platybasia" is derived from the Greek words "platys" meaning flat and "basis" meaning base, referring to the flat base of the skull.
Definition
Platybasia is a condition where the angle between the clivus and the foramen magnum is increased. This results in the flattening of the base of the skull. It is often associated with basilar invagination, a condition where the top of the second cervical vertebra migrates upward.
Symptoms
Symptoms of Platybasia can vary, but may include headaches, dizziness, difficulty swallowing, and changes in vision. In severe cases, it can lead to neurological issues due to the compression of the brainstem and the upper spinal cord.
Diagnosis
Diagnosis of Platybasia is typically made through imaging studies such as MRI or CT scans. These can show the abnormal angulation and any associated conditions such as basilar invagination.
Treatment
Treatment for Platybasia often involves surgery to correct the abnormal angulation and relieve any pressure on the brainstem or spinal cord. This may involve a procedure known as a decompression surgery.
