The distinctive head shape seen in kleeblattschaedel is caused by the closure of the sagittal, coronal, and lambdoid sutures, with subsequent bulging of the cranial contents leading to a trilobate head shape. [7] The condition is also caused by absence of the coronal and lambdoid sutures. [10] Conditions with kleeblattschaedel include: [11] [12]
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.
This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids ( ptosis ), widely spaced eyes ( hypertelorism ), and minor abnormalities of the hands and feet ( syndactyly ). [ 2 ]
Scaphocephaly or sagittal craniosynostosis is a type of cephalic disorder which occurs when there is a premature fusion of the sagittal suture.Premature closure results in limited lateral expansion of the skull, resulting in a characteristic long, narrow head. [1]
Caput succedaneum is a benign neonatal condition involving a serosanguinous (containing blood and serum), subcutaneous, extra-periosteal fluid collection with poorly defined margins caused by the pressure on the presenting part of the fetal scalp by the vaginal walls and uterus as the infant passes through a narrowed cervix during delivery.
Turricephaly is a type of cephalic disorder where the head appears tall with a small length and width. [3] [4] It is due to premature closure of the coronal suture plus any other suture, like the lambdoid, [5] or it may be used to describe the premature fusion of all sutures. [2] It should be differentiated from Crouzon syndrome.
When the vacuum is applied to the infant's head, the tension creates a difference in pressure between the atmosphere and the infant's scalp that causes the soft tissue layers of the scalp to fill inside the suction cup. [5] [6] Subsequently, interstitial fluid and small hemorrhages build up, causing the head to swell and forming a localized edema.
