Abstract Pycnodysostosis (MIM# 265800) is a subtype of osteopetrosis and is a rare skeletal
dysplasia characterized by generalized progressing osteosclerosis. The prevalence is 1 …

Objectives This study aimed to establish the frequency of the frontal sinus (FS) aplasia, to
compare metopic and nonmetopic series and thus to assess the relationship between the …

Background: This study aimed to investigate the incidence, topographical distribution,
morphology, and interrelationship of the metopism and Wormian bones (WBs) in dry adult …

Biarmosuchia is a clade of basal therapsids that includes forms possessing plesiomorphic
'pelycosaurian'cranial characters as well as the highly derived Burnetiamorpha which are …

Background Cranial sutures are active bone growth sites and any alteration in their normal
formation, patency and closure influences the overall cranial morphology. This comparative …

The frontal bone develops as two halves, which further unite in a single bone by the closure
of the mid-sagittal metopic suture, typically by the end of the first postnatal year. The frontal …

The co-occurrence of a bregmatic bone and metopism is an extremely rare finding. In the
present study we investigate, compare, and describe this uncommon combination in two …

The squamous part of the occipital bone is a place of many different variations. They are a
result of faulty ossification in the occipital squama or due to the presence of sutural bones in …

Background Metopic suture lies between the halves of the growing frontal bone and usually
closes in early infancy. If the metopic suture fails to close it persists in adulthood and could …

The persistent metopic suture is an anatomic variation related to a specific skull
configuration. Data on the proportionality of the neurocranium and the occurrence of …
