2

Neuroimaging surveillance

Regular skull imaging with CT or MRI to monitor for progressive changes in bone morphology, assess intracranial structures, and evaluate need for intervention. Typically performed annually or as symptoms dictate.

3

Cranioplasty

Surgical reconstruction of parietal bone abnormalities using autologous bone grafts or synthetic materials to restore protective coverage and aesthetic contour. Reserved for significant deformities or functional impairment.

Additional treatment options

Cervicothoracic strengthening

Targeted physical therapy to address postural changes and musculoskeletal adaptations secondary to abnormal parietal bone morphology. Includes cervical stabilization and scapular strengthening exercises.
