Caput succedaneum typically presents as a soft, boggy, uneven mass that crosses cranial suture lines. The size of the caput is typically 1-2 cm deep with a varying circumference dependent on degree of injury. Petechiae, purpura, and ecchymoses (bruises) may also be present. Since the fluid collection is not bound by suture lines, the swelling ...
A subgaleal hemorrhage may initially look like a caput succedaneum or a chignon because blood crosses the suture lines for all three conditions. [6] However, notifiable signs of a subgaleal hemorrhage include fluctuant scalp swelling, a lesion crossing the suture lines, pitting edema continuing over the head, and fluid wave test. [21]
A cephalohematoma (American English), also spelled cephalohaematoma (British English), is a hemorrhage of blood between the skull and the periosteum at any age, including a newborn baby secondary to rupture of blood vessels crossing the periosteum.
The swelling may obscure the fontanel and cross cranial suture lines, distinguishing it from cephalohematoma, [2] in which the bleed is confined by its subperiosteal location. [3] Patients with subgaleal hemorrhage may also have significant hyperbilirubinemia due to resorption of hemolyzed blood. Laboratory studies may demonstrate reduced ...
Premature complete ossification of these sutures is called craniosynostosis. In Latin, the word calvaria is used as a feminine noun with plural calvariae ; however, many medical texts incorrectly list the word as calvarium , a neuter Latin noun with plural calvaria .
The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
The two sides of the forehead are marked by the temporal ridge, a bone feature that links the supraorbital ridge to the coronal suture line and beyond. [1] [2] However, the eyebrows do not form part of the forehead. In Terminologia Anatomica, sinciput is given as the Latin equivalent to "forehead" (etymology of sinciput: from semi-"half" and ...
The ecdysial suture is longitudinally placed on the vertex, separating the epicranial halves of the head to the left and right sides. Depending on the insect, the suture may come in different shapes: like either a Y, U or V. Those diverging lines that make up the ecdysial suture are called the frontal or frontogenal sutures.
