All About Cranial Bones

To protect the brain, skill provides the structure to the face and head. Skull bones can be categorized into cranial bones which contribute to making cranium and face bones make the entire face.

Several kinds of bones are present in the body and it can be categorized into the following:

  1. Long bones
  2. Short bones
  3. Flat bones
  4. Irregular bones
  5. Sesamoid bones

Cranium Can Be Categorized Into Two Parts:

  1. Flat bones: Most of the bones that fall into this type are plane and thin, except a few which have a curve.
  2. Irregular bones: It is not a common type of bones; these bones have complex structures and cannot be categorized into types.

Composition And Function:

Cranial bones can be divided into 8 types which supports the skull:

  1. Ethmoid bone: It is in the front of the skull forms the nasal activity.
  2. Sphenoid bone: It is in the front of the skull, which creates parts of the orbital sockets.
  3. Frontal bone: It forms the forehead and it is a flat bone and also contributes to creating the upper socket of the eyes.
  4. Occipital bone: It is the base of the skull.
  5. Two Parietal bones: The two expansive parietal bones are associated and makeup portion of the roof and sides of the human cranium.
  6. Two temporal bones: It is at the base and sides of the skull.


The cranial bones are held together by one of the kind joints called sutures, which are made of thick connective tissue. They’re sporadically formed, permitting them to firmly connect all the extraordinarily formed cranial bones. The sutures don’t meld until adulthood, which permits your brain to proceed developing amid childhood and puberty.

Cranial Bone Conditions:

Injuries to bones and other health conditions can impact the functionality of the cranial bones. It could be a fracture or congenital conditions. Injuries should be handled delicately, and immediate treatment needs to be done in case of any problem in face movements.


It is a condition in which a bone is broken or dislocated. Numerous kinds of fractures on skull bones may affect the look or functionality of the bones.

  1. Depressed fracture: A depressed cranium break may be a break in a cranial bone with depression of the bone in toward the brain. A compound break includes a break-in, or misfortune of, skin and chipping of the bone. It mainly causes when heavy thing such as hammer is hit on the head or severe head injuries during road accidents.
  2. Linear fracture: A straight cranium break could be a break in a cranial bone taking after a lean line, without fragmenting, depression, or twisting of bone. The reason behind linear fracture is a full force and the energy is transferred to the skull.
  3. Basilar: A basilar cranium break could be a break of a bone within the base of the cranium. Side effects may incorporate bruising behind the ears, bruising around the eyes, or blood behind the eardrum. Major of the basilar cases are a result of CNS injury or cervical spine fracture.
  4. Diastatic: A break that takes after a cranial suture and causes it to separate. A diastatic break happens along one of the sutures of your cranium, making it more extensive than normal. It’s as a rule seen in newborn children.

In most of the cases, these fractures are self-healing without any treatment or surgery, only severe fractures cause problems and to do surgery in critical conditions. The entire process hardly takes 5 to 10 days to completely recover in the original state.


It is a condition in newborn babies, many babies born with Craniosynostosis, which is the early closure of sutures. It results in an unusual face structure and sometimes affects facial movements.

The treatment for craniosynostosis is surgery to make sure that, the child’s brain has sufficient room to develop. Specialists open the combined sinewy creases in your child’s cranium. Surgery makes a difference the cranium develops into a more commonplace shape and anticipates a buildup of weight on the brain.

If it is not treated on time, then it results in serious complications including unusual head shape and high pressure on the brain.

Though it is not an inherited disease but some genes from the last generation has been passed to the child that causes this condition. The chances of this disease are twice in men as compared to women.

It Could Be Of Different Types:

  1. Bi-coronal synostosis: The most side effects of bi-coronal craniosynostosis are the compliment appearance of the forehead and eye attachments and a head shape that’s shorter front to back and taller than normal.
  2. Coronal synostosis: In newborns, the bones of the cranium are isolated by little spaces or development plates called sutures. One seam runs over the best of the cranium from ear-to-ear. This coronal suture may near rashly on one side that is uni-coronal or both sides that bi-coronal. When this happens, it is called coronal synostosis.
  3. Lambdoid synostosis: This may lead to smoothing on one side of the back of the cranium. It can influence the situating of the ear or cause the cranium to tilt sideways.
  4. Metopic synostosis: The child creates a discernible edge amplifying along the center of her forehead. Her brow will see excessively narrow. Her eyes may be dispersed as well close together. The front of her cranium may show up pointed and or maybe triangular.
  5. Sagittal synostosis: Sagittal craniosynostosis happens when certain bones in a child’s cranium combine rashly. At birth, a child’s cranium is made up of a few partitioned bones with development plates between them. Since the cranium isn’t a strong piece of bone however, the brain can develop and extend in the estimate.

It requires surgical treatment to avoid issues in the future. After treatments, close monitoring is required to check the effects and proper growth of the brain, as it is a critical part of the body.

Other Conditions:

  1. Cleidocranial dysplasia: Cleidocranial dysplasia is an autosomal overwhelming skeletal dysplasia characterized by anomalous clavicles, obvious sutures and fontanelles, supernumerary teeth, brief stature, and an assortment of other skeletal changes.
  2. Craniometaphyseal dysplasia: It could be a hereditary skeletal condition characterized by the dynamic thickening of bones within the skull and anomalies at the closes of long bones within the appendages. The abundance of bones within the head can lead to particular facial highlights and postponed tooth emission, as well as compression of the cranial nerves
  3. Paget’s disease of bone: Paget’s illness of bone meddling along with your body’s typical reusing handle, in which modern bone tissue continuously replaces ancient bone tissue. Over time, the infection can cause influenced bones to get to be delicate and distorted. Paget’s disease of bone most commonly happens within the pelvis, cranium, spine, and legs.
  4. Fibrous dysplasia: It may be a kind bone condition in which irregular stringy tissue creates instead of typical bone. As these ranges of stringy tissue develop and grow over time, they can debilitate the bone, which is causing it to break or get to be distorted.
  5. Osteomas: Osteomas are generous outgrowths of bone found basically on the bones of the cranium. These tumors are moderate developing and as a rule cause no side effects.

Symptoms Of A Cranial Bone Condition:

Sometimes it is difficult to check the symptoms of the cranial bone, as it is a complex structure and difficult to point the exact problem.

Symptoms To Check The Issues Related To Fracture:

  1. Staining near the eyes or behind the ears
  2. Clear liquid or blood depleting from the ears or nose
  3. A feeling of shortcoming in the face

Symptoms Of A Basic Issue With The Cranial Bones Include: 

  1. A gloomy, throbbing pain
  2. numbness or shivering in your face
  3. hearing or vision problems
  4. unusually formed head or facial highlights

Tips For Healthy Cranial Bones:

Cranial bones are the protective system of the skull and the entire face and head shape are dependent on it. It is extremely important to prevent it from severe injuries as it affects the brain directly.

Below Steps Can Be Taken For The Safety Of These Bones:

  1. Always wear a helmet: Major injuries related to cranial bones are due to road mishaps which can be avoided using helmets while driving any vehicle or playing games such as skates. Always buy new helmets and don’t use broken ones.
  2. Seatbelt:It is a protection tool to prevent many injuries not only the brain but also the entire body. Always tight the seatbelt before start driving.
  3. Reduce the risk of falling: Secure anything, such as free electrical ropes, that may cause somebody to trip. In case you’ve got portability issues, consider introducing handrails and snatch bars in regions, such as the shower or stairs.

In case you’ve got a newborn child, be beyond any doubt to monitor their head for anything abnormal. You’ll be able to make beyond any doubt your child doesn’t remain in one position for as well long. A few ways to do this include:

  1. Change the way of the baby’s head faces when putting them to bed
  2. Hold baby in arms when they’re wakeful rather than setting them in a lodging, swing, or carrier.
  3. When possible changing the arms, the mother should hold the child with when feeding.
  4. Allowing the child to play on their stomach beneath near supervision.


Though, our body is able to heal the cranial bones problems or fractures but in normal cases. In severe cases or infants suffering from birth needs to take the help of medical treatments to cure it at an early stage. Surgery may be needed to help avoid brain damage. This will usually be carried out under general anesthetic.

Treatment will depend on a few variables. Your specialist will take into thought your age, wellbeing, and restorative history, as well as the sort of break, its gravity, and any coming about brain wounds.
