In which syndrome might you find a lack of facial expression and difficulty swallowing?

• A. Pulmonary Hypoplasia
• B. Kartagener Syndrome
• C. Moebius Syndrome
• D. Stendhal Syndrome

Answer: (C)

Moebius Syndrome is characterized by a profound inability to move certain facial muscles, leading to a lack of facial expression. This occurs due to congenital cranial nerve VI and VII (abducens and facial nerves) palsy. Individuals with Moebius Syndrome often exhibit facial paralysis, which severely affects their ability to smile, frown, or show other expressions. Furthermore, this condition can result in difficulties with swallowing, also known as dysphagia, as both facial and cranial nerves play significant roles in the coordination of the muscles used for swallowing. The neural deficiencies in this syndrome can directly impact the movements necessary for effective swallowing and other oral motor functions. In contrast, the other syndromes listed do not typically present with these specific symptoms. Pulmonary Hypoplasia relates to underdeveloped lungs and does not include facial muscle involvement. Kartagener Syndrome is primarily associated with respiratory issues and situs inversus due to ciliary dysfunction. Stendhal Syndrome is a psychosomatic condition triggered by art exposure, and does not involve physical anatomical defects or neurological components affecting facial expression or swallowing.
