Psychomotor Development Delays Psychomotor development refers to the changes experienced directly after birth through adolescence. Development occurs in cognitive, emotional, motor, and social skills over the child's growth and a delay can result in lagging development of language, motor skills, cognition, or social skills, however these delays can vary in severity. Facial Dysmorphism Facial Dysmorphisms broadly describe any abnormalities in facial structure. Facial Dysmorphisms include slopping forehead, frontal bossing (prominent protruding forehead), hemifacial microsomia (one side of the face underdeveloped), and otocephaly (absence of mandible and fusion of ears under chin). Malformation of Limbs Congenital limb defects occur when a fetus' limbs, either upper or lower, experience altered development. These developmental abnormalities include absence of the limb, failure of portions of the limb to separate (commonly fingers and toes), duplication of digits, or overgrowth or undergrowth of limbs.
