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]
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.
Surgery [3] 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.
The frontal sinus is hollow, and thus it can be more difficult to remove bossing there. If the bone over the frontal sinus is thick enough the bossing can be removed by simply grinding down the bone. However, in some people, the wall of bone is so thin that it is not possible to grind the bossing away completely without breaking through the ...
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.
Craniofacial surgery is a surgical subspecialty that deals with congenital and acquired deformities of the head, skull, face, neck, jaws and associated structures. Although craniofacial treatment often involves manipulation of bone, craniofacial surgery is not tissue-specific; craniofacial surgeons deal with bone, skin, nerve, muscle, teeth ...
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 ...
Endonasal transsphenoidal surgery is a less invasive procedure with a shorter recovery time than the older method of transsphenoidal surgery, and the likelihood of removing the entire tumor is greater with reduced side effects. Consequently, endonasal transsphenoidal surgery is the more common surgical choice. [citation needed]
