Developmental variations in the cranial vault arise during early ontogenesis due to premature or delayed suture closure, non-union between normal ossification centers, and emergence of additional centers. These cause abnormal calvarial partition are often associated with modifications overall configuration. This study aims evaluate impact metopic persistence development supernumerary bones occi...

BACKGROUND Frontal sinuses are 2 irregular cavities, placed between 2 lamina of frontal bone. Expansion continues during childhood and reaches full size after puberty. Persistent metopic suture is one of the factors that are related to abnormal frontal sinus development. In this study, we want to discuss about the coexistence of persistent metopic suture and abnormal frontal sinus development u...

Introduction Frontal bone of the skull develops in two halves during the fetal life separated by the metopic suture. The suture normally disappears soon after the birth [1]. The persistent complete metopic suture extending from the nasion to bregma is called metopism [2]. Lambda represent the meeting point of the sagittal and lambdoid suture. It represents the site of posterior median fontanel ...

Majority of Skull bones are held together by fibrous joints termed as sutures. At birth the two halves of frontal bone remain separate as the metopic suture which is replaced by bone at about 2 years. The persistence of this suture beyond 8 years of age is termed as metopism. The study was conducted on 90 adult human dry skulls. Among them 55 were obtained from department of anatomy RIMS Ongole...

E-Mail: [email protected] Introduction: Metopic suture is present between developing frontal bones. It disappears approximately by 2-3 years and latest by 8 years of age. The persistence of this suture is termed as metopism. It may persist normally without ...

Falk and colleagues [Falk D, Zollikofer CP, Morimoto N, Ponce de León MS (2012) Proc Natl Acad Sci U S A 109(22):8467-8470] hypothesized that selective pressures favored late persistence of a metopic suture and open anterior fontanelle early in hominin evolution, and they put an emphasis on the Taung Child (Australopithecus africanus) as evidence for the antiquity of these adaptive features. Th...
