Hemifacial microsomia is commonly associated with which of the following features?

• A. Ear malformation
• B. Laryngeal dysfunction
• C. Webbed fingers and toes
• D. Widely spaced eyes

Answer: (A)

Hemifacial microsomia occurs when tissues on one side of the face don’t develop fully, most noticeably affecting the jaw and ear region. The ear’s development is tightly linked to the same embryologic structures that form the face, so ear malformations (such as microtia or anotia) are by far the most common associated feature. Other options don’t fit as well: laryngeal dysfunction isn’t a typical hallmark of this condition, and webbed fingers/toes or widely spaced eyes aren’t characteristic associations.
