All rights reserved.  Developmental Competence: Infants and Children (1 of 2)  Bones of neonatal skull are separated by sutures and fontanels, spaces where the sutures intersect.  These membrane-covered “soft spots” allow growth of brain during first year; gradually ossify.  Closure of fontanels  Triangle-shaped posterior fontanel closes by 1 to 2 months.  Diamond-shaped anterior fontanel closes between 9 months and 2 years.  During fetal period, head growth predominates.  Head size is greater than chest circumference at birth and reaches 90% of final size at 6 years old. Copyright © 2020 by Elsevier Inc. All rights reserved.  Developmental Competence: Infants and Children (2 of 2)  During infancy, trunk growth predominates  so that head size changes in proportion to body height.  Facial bones grow at varying rates.  In toddler, mandible and maxilla are small and nasal bridge is low.  Lymphoid tissue  Well developed at birth and grows to adult size when the child is 6 years old  In adolescence  facial hair also appears on boys at this time: first on upper lip, then on cheeks and lower lip, and last on the chin.  noticeable enlargement of the thyroid cartilage occurs, and with it, the voice deepens. Copyright © 2020 by Elsevier Inc. All rights reserved.  Developmental Competence  Pregnant female  Thyroid gland enlarges slightly during pregnancy as a result of hyperplasia of tissue and increased vascularity.  Aging adult  Facial bones and orbits appear more prominent.  Facial skin sags resulting from decreased elasticity, decreased subcutaneous fat, and decreased moisture in skin.  Lower face may look smaller if teeth have been lost.

All rights reserved.  Inspection and Palpation of the Skull  Size and shape  Normocephalic: round and symmetric  Assess shape: place fingers in person’s hair and palpate scalp  Cranial bones that have normal protrusions:  Forehead, lateral edge of parietal bones, occipital bone, and mastoid process behind each ear  Temporal area  Palpate temporal artery above zygomatic (cheek) bone between eye and top of ear Copyright © 2020 by Elsevier Inc. All rights reserved.  Inspection of the Face  Facial structures  Always should be symmetric.  Note facial expression and appropriateness to behavior or reported mood.  Note any abnormal facial structures  Coarse facial features, exophthalmos, changes in skin color or pigmentation, or abnormal swellings  Note any involuntary movements (tics) in facial muscles; normally none occur. Copyright © 2020 by Elsevier Inc. All rights reserved.  Inspection and Palpation of the Neck (1 of 2)  Head and neck symmetry  Head position is centered in midline, and accessory neck muscles should be symmetric.  Head should be held erect and still.  Range of motion  Note any limitations.  Test muscle strength.  Observe for enlargement of glands and/or pulsations.  Lymph nodes  Palpate nodes noting location, size, shape, delimitation, mobility, consistency, and tenderness. Copyright © 2020 by Elsevier Inc. All rights reserved.  Inspection and Palpation of the Neck (2 of 2)  Trachea  Should be midline  Palpate for any tracheal shift  Note any deviation from midline  Thyroid gland  Difficult to palpate; check for enlargement, consistency, symmetry, and presence of nodules  Position patient for best approach Posterior approach Anterior approach  Auscultate thyroid for bruit, if enlarged. Copyright © 2020 by Elsevier Inc. All rights reserved.  Examining Lymph Nodes  Using a gentle circular motion of finger pads, palpate lymph nodes.  Beginning with preauricular lymph nodes in front of ear, palpate the 10 groups of lymph nodes in routine order  Many nodes are closely packed, so you must be systematic and thorough in your examination.  Do not vary sequence or you may miss some small nodes.

All rights reserved. Thyroid Palpation: Posterior Approach Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Infants and Children (1 of 2)  Skull  Measure infant’s head at each visit up to age 2 years and yearly up to age 6 years. Note infant’s head posture and head control; infant can turn head side to side by 2 weeks.  Two common variations in newborn cause shape of skull to look markedly asymmetric due to birth trauma: Caput succedaneum: edematous swelling that is self-limiting and extends across suture lines Cephalohematoma: subperiosteal hemorrhage, well defined over one cranial bone over periosteum, reabsorbed during first few weeks of life Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Infants and Children (2 of 2)  Skull  Molding Overriding of the cranial bones during birth process that resolves over a few days or a week  Positional molding (positional plagiocephaly) Flattening of the head due to infant sleeping position  Fontanels Observe anterior and posterior fontanel.  Head and neck control Observe for appearance of tonic neck reflex which disappears between 3 and 4 months of age. Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Infants and Children: Face  Check facial features for symmetry, appearance, and swelling.  Note symmetry of wrinkling when infant cries or smiles (e.g., both sides of lips rise and both sides of forehead wrinkle).  Normally, no swelling is evident.  Parotid gland enlargement best seen when child looks up; swelling appears below angle of jaw Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Infants and Children: Neck  An infant’s neck looks short; it lengthens during the first 3 to 4 years.  Assess muscle development with gentle passive ROM.  Cradle infant’s head with your hands and turn it side to side and test forward flexion, extension, and rotation.  Note resistance to movement, especially flexion.  During infancy, cervical lymph nodes are not palpable normally, but child’s lymph nodes are palpable.  Palpable nodes less than 3 mm are normal.  Children have a higher incidence of infection, so you will expect a greater incidence of inflammatory adenopathy; no other mass should occur in neck. Copyright © 2020 by Elsevier Inc. All rights reserved.  Infants and Children: Special Procedures  Percussion  With an infant, you may directly percuss with your plexor finger against head surface. This yields a resonant or “cracked pot” sound, which is normal before closure of fontanels.  Auscultation  Bruits are common in skull of children under 4 or 5 years of age or children with anemia. Systolic or continuous; heard over temporal area Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Pregnant Female  During second trimester  chloasma may show on face. A blotchy, hyperpigmented area over cheeks and forehead that fades after delivery  Thyroid gland may be palpable normally during pregnancy. Copyright © 2020 by Elsevier Inc. All rights reserved.  Physical Examination: Aging Adult  Temporal arteries  may look twisted and prominent.  In some aging adults, a mild rhythmic tremor of head may be normal.  senile tremors are benign and include head nodding and tongue protrusion.  If some teeth have been lost  lower face looks unusually small, with mouth sunken in.  Neck may show an increased concave curve  to compensate for kyphosis.  Maintain patient safety by indicating patient perform ROM and position changes slowly  minimize potential for dizziness.
