Skull bossing is a descriptive term in medical physical examination indicating a protuberance of the skull, most often in the frontal bones of the forehead ("frontal bossing"). Although prominence of the skull bones may be normal, skull bossing may be associated with certain medical conditions, [ 1 ] including nutritional, metabolic, hormonal ...
[10] [11] This is best seen in a view standing above the child looking downward at the top of the head. [12] Compensatory growth occurs forward at the coronal suture and backward at the lambdoid suture giving respectively a prominent forehead, called frontal bossing, and a prominent back portion of the head, called coning.
Cranial sutures. A defining characteristic of Crouzon syndrome is craniosynostosis, which results in an abnormal head shape.This is present in combinations of: frontal bossing, trigonocephaly (fusion of the metopic suture), brachycephaly (fusion of the coronal suture), dolichocephaly (fusion of the sagittal suture), plagiocephaly (unilateral premature closure of lambdoid and coronal sutures ...
Trigonocephaly is a congenital condition due to premature fusion of the metopic suture (from Ancient Greek metopon 'forehead'), leading to a triangular forehead. The premature merging of the two frontal bones leads to transverse growth restriction and parallel growth expansion.
The compensatory head-growth forward at the coronal suture gives a prominent forehead, frontal bossing and a prominent back of the head, called coning. [5] The incidence of scaphocephaly is 2.8 per 10,000 births in the Netherlands; therefore, it is the most common form of craniosynostosis. [6] [7]
Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes. The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor.
The Type III forehead is the most common situation and occurs in more than 90% of patients. The forehead, in this situation, has a prominent bossing across the top of the brows, and that bossing is overly projected. A frontal sinus is present. The thinness of the sinus precludes using exclusively rotary instruments to thin the bone.
The face, especially in children, has distinct characteristics including a short nose with upturned nares, thickened upper lip with a thin vermilion upper border, frontal bossing, small jaw, low-set posteriorly rotated ears, sunken appearance in the middle of the face, and hypertelorism of eyes. The forehead is prominent with bitemporal ...
