Frontal bossing is the development of an unusually pronounced forehead which may also be associated with a heavier than normal brow ridge. It is caused by enlargement of the frontal bone, often in conjunction with abnormal enlargement of other facial bones, skull, mandible, and bones of the hands and feet.
Because of the abnormal forehead, there is less space for the normal facial features to develop. This results in shallow eye sockets and flat cheekbones. The shallow eye sockets make the eyes more prominent or bulging and cause the eyes to be more separated than normal (hypertelorism).
Craniosynostosis is a condition in which one or more of the fibrous sutures in a young infant's skull prematurely fuses by turning into bone (ossification), [2] thereby changing the growth pattern of the skull. [3]
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 ...
large, bulging head; prominent scalp veins "saddle-like, flat bridged nose with broad, fleshy tip" large lips and tongue; small, widely spaced and/or malformed teeth; hypertrophic alveolar ridges and/or gums; The head tends to be longer than normal from front to back, with a bulging forehead.
Bossing (bulging) of the forehead. Open skull sutures, large fontanelles. Hypertelorism. Delayed ossification of bones forming symphysis pubis, producing a widened symphysis. Coxa vara can occur, limiting abduction and causing Trendelenburg gait. Short middle fifth phalanges, [14] sometimes causing short and wide fingers. [15] Vertebral ...
The frontal suture is a fibrous joint that divides the two halves of the frontal bone of the skull in infants and children. Typically, it completely fuses between three and nine months of age, with the two halves of the frontal bone being fused together.
The breast bone may either protrude or be sunken, while the spine may be abnormally curved. [1] Intelligence is often normal. [1] Complications of NS can include leukemia. [1] A number of genetic mutations can result in Noonan syndrome. [1] The condition may be inherited as an autosomal dominant condition or occur as a new mutation.
