Anatomy of the Infant Head
Because infant anatomy of the head differs greatly from adult cranial
anatomy, Dr. James Bosma of the National Institute of Dental Research
wanted to produce a reference guide on infant anatomy for pediatricians,
pediatric dentists, maxillo-facial surgeons, and other physicians. Bosma
hoped that by learning more about the development of the infant airway,
throat, larynx, and pharynx, that doctors could better understand breast
feeding and respiratory abnormalities. Bosma asked Howard Bartner to collaborate
with him and three other illustrators in the study and description of
the infant head, resulting in the publishing of Anatomy of the Infant
Head (Johns Hopkins University Press, 1986). Bartner's elegant illustrations
are important features of this classic text.
Drawings 1-3: Sequential Dissections of the Head from the Side
Below are side-view drawings of an infant's head. Note the nugget of extra
fat, known as the "buccal pad." The buccal pad contributes to babies'
chubby cheeks and diminishes when the infant is about a year old. Drawings
two and three depict arrangements of the jaw and throat muscles.
Drawings 4-6: Sequential Views of the Infant's Throat, Larynx
Areas, and Mouth Muscles from the Front
Removal of the skin shows tissue and muscles in the throat area. Note
how the drawings become progressively more detailed as the levels of dissection
go deeper. The left side of drawing 6 is a working sketch; the finished
product is on the right.
Drawings 7-9: Sequential Drawings of the Throat Area from the
Back
The following drawings show the back of an infant's head. Drawing seven
depicts the relation between the pharynx and vessels and nerves on each
side of it. The eighth drawing illustrates the ear as seen from the back;
and the ninth drawing is a close-up of the pharynx and layrnx areas.
