Doctor insights on:
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Craniosynostosis: The skull is made of many bone plates which are not fully fused at birth, allowing for adequate brain development. Fibrous tissue between the plates (cranial sutures) calcifies as brain growth slows during the first five or so years. Premature fusion of the plates can cause a mis-sharpen head or inhibit brain growth. Not all fused sutures are worrisome. The only treatment, if required, is surgery. ...Read more
None.: As a newborn, none of the skull bones are fused; there are membranes/cartilage that fill spaces between them. Gradually this converts to bone (ossification), mostly during childhood, but process may not be complete till age 25! if they fuse prematurely, will cause intracranial pressure, head pain, visual problems, and unusual head shapes causing low self-esteem. Craniosynostosis requires surgery. ...Read more
Check w/ doctor: It is important to be certain the baby does not have any other birth defects. Some infants with skull bones that have grown together ("cranioynostosis") have a "sundrome" (a recognized group of birth defects). A syndrome can often be diagnosed on physical examination of the entire infant and, increasingly, by dna testing. Your pediatrician may refer you to a medical geneticist for this testing. ...Read more
Knitted skull bones: The infant skull is composed of growth plates designed to grow pushing away from each other. After 9y, the plates knit as the adult head size is reached.Knitting up too early will form ridges & distort the shape of the skull.When this occurs, the knitted area can be released surgically as an open procedure or through a scope. I've cared for 3 in my practice in 3 decades & they have done fine. ...Read more
What could a hard bump that doesn't move on my head be? It hurts when I put pressure on it, and it feels like the pain is coming from the skull bone.
My skull bone on the right side of my head by the top on my ear is bigger than my left. Is this normal?
Yes: Yes, almost all of us are asymmetrical. ...Read more
Is bone age always the same for every bone?ie,if a wrist x-ray showed a delay in bone age of 2 years, would face /skull bones also be delayed 2 years?
Not necessarily, but: B"sd thats a very insightful question. Generaly, endocrinologist accept that the bone age determined from 1 hand /wrist x ray applies to the whole body. Although, not necesarrily true, bone age os determined is clinicaly useful to identify growth delay and can be used to indicate further evaluation and to follow changes over time. So the test seems to serve its purpose. Always glad to discuss. ...Read more
