Which syndrome is BEB associated with when lower facial abnormalities are present?

• A. Horner's syndrome
• B. Meige's syndrome
• C. Möbius syndrome
• D. Blepharophimosis

Answer: (B)

Blepharospasm that includes involvement of the lower face is Meige's syndrome. This is a craniocervical dystonia where blepharospasm (involuntary eyelid closure) occurs together with oromandibular dystonia, affecting the jaw and lower facial muscles. The other conditions don’t combine eyelid spasm with lower facial dystonia: Horner's presents with ptosis and pupil constriction due to autonomic causes, Möbius involves congenital facial nerve palsy with limited eye movements, and Blepharophimosis is a congenital eyelid malformation.
