Congenital Cranial Dysinnervation Disorders (CCDD) are a group of rare conditions that affect the nerves controlling eye and facial movements. These disorders are present at birth and result from abnormal development of cranial nerves, which can lead to issues such as strabismus (crossed eyes) or facial weakness. Symptoms of CCDD can vary widely, but they often include difficulties with eye coordination, facial expressions, and sometimes hearing. Diagnosis typically involves a thorough clinical evaluation and imaging studies. Treatment may include physical therapy, surgery, or other interventions to improve function and appearance.
