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.
Kagami-Ogata syndrome is a rare genetic disease that is caused by mutations on Maternal chromosome 14 or by paternal UPD(14). [1] The main signs of this disease are: polyhydramnios, narrow bell-shaped thorax, coat-hanger-like ribs, abdominal wall defect, enlarged placenta. [2]
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. [10] [11] This is the most common form of craniosynostosis. [13]
Paget's disease affecting the skull may cause frontal bossing, increased hat size, and headaches. Often patients may develop loss of hearing in one or both ears [ 7 ] due to auditory foramen narrowing and resultant compression of the nerves in the inner ear.
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 ...
Metopism is the condition of having a persistent metopic suture, [2] or persistence of the frontal metopic suture in the adult human skull. [3] Metopism is the opposite of craniosynostosis. [4] The main factor of the metopic suture is to increase the volume of the anterior cranial fossa.
Those affected have an average adult height of 131 centimetres (4 ft 4 in) for males and 123 centimetres (4 ft) for females. [3] Other features can include an enlarged head with prominent forehead (frontal bossing) [3] and underdevelopment of the midface (midface hypoplasia). [6] Complications can include sleep apnea or recurrent ear infections ...
Jackson–Weiss syndrome (JWS) is a genetic disorder characterized by foot abnormalities and the premature fusion of certain bones of the skull (craniosynostosis), which prevents further growth of the skull and affects the shape of the head and face.
