Dolichocephaly (derived from the Ancient Greek δολιχός 'long' and κεφαλή 'head') is a term used to describe a head that is longer than average relative to its width. In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as the Lurcher or German Shepherd) have elongated noses.
Dolichocephaly Variable sagittal craniosynostosis penetrance. [64] Craniosynostosis-anal anomalies-porokeratosis syndrome: Coronal, sagittal Brachycephaly [65] Craniosynostosis-Dandy-Walker malformation-hydrocephalus syndrome: Sagittal Dolichocephaly [66] Craniosynostosis-fibular aplasia syndrome [67]
A synonymous term is 'dolichocephaly' (the prefix 'dolicho-' means elongated). [9] Premature sagittal suture closure restricts growth in a perpendicular plane, thus the head will not grow sideways and will remain narrow. [10] [11] This is best seen in a view standing above the child looking downward at the top of the head. [12]
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 ...
Brachycephaly (derived from the Ancient Greek βραχύς, 'short' and κεφαλή, 'head') is the shape of a skull shorter than average in its species.It is perceived as a cosmetically desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species.
Facial deformities with Smith-Fineman-Myers syndrome. SFMS affects the skeletal and nervous system. This syndrome's external signs would be an unusual facial appearance with their heads being slightly smaller than average, a narrow face (clinically known as dolichocephaly), a large mouth with a drooping lower lip that is held open, protruding upper jaw, widely spaced upper front teeth, an ...
Cephalic index viewed from above the head. The cephalic index or cranial index is a number obtained by taking the maximum width (biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length (occipitofrontal diameter or OFD, front to back).
Apert syndrome is a form of acrocephalosyndactyly, a congenital disorder characterized by malformations of the skull, face, hands and feet. It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible.
