Are there certain facial features associated with Trisomy 13?
Some babies with trisomy 13 have similar facial features. These can include small eyes (microphthalmia), openings in the lip or roof of the mouth (cleft lip/ palate), small head size (microcephaly), a broad, flat nose, eyes slightly farther apart than normal (ocular hypertelorism), and low set ears. Some babies with trisomy 13 may have missing eyes, or the nose may be misplaced on the face.
