Which statement is NOT listed as a cranial nerve impairment in spina bifida?

• A. Hearing loss
• B. Ocular muscle palsies
• C. Swallowing difficulty
• D. Croupy/hoarse cry

Answer: (A)

In spina bifida, especially when brainstem structures are involved (as seen with Chiari II associations), certain cranial nerves are more commonly affected, mainly those that control eye movements and the core functions of swallowing and voice. Ocular muscle palsies reflect involvement of the nerves that move the eyes, and swallowing difficulty points to dysfunction of nerves that control swallowing and the pharynx. A croupy or hoarse cry indicates issues with the vagus nerve affecting laryngeal muscles. Hearing loss, which involves the vestibulocochlear nerve, is not typically listed among the cranial nerve impairments described in spina bifida, so it stands out as not being part of the usual cranial nerve impairment pattern in this condition.
