##While it's common for the shape of people's skulls to vary
, a new dent or irregularity in your skull can occasionally indicate a serious health condition. Dents in your skull can be caused by trauma, cancer, bone diseases, and other conditions.

Lastly, is it normal to have bumps and ridges on skull?
Not everyone has the same skull shape, and normal variations exist among individuals. The skull is not perfectly round or smooth, so it is normal to feel slight bumps and ridges. However, a dent in the head, especially if it is new, requires a trip to the doctor to determine the cause.
From everywhere, does the skull get larger with age? Since most bones in the body stop growing after puberty, experts assumed the human skull stopped growing then too. But using CT scans of 100 men and women, the researchers discovered that the bones in the human skull continue to grow as people age.
In short, why do I have a ridge in my skull?
The gaps between the plates allow for growth of the skull. The places where these plates connect are called sutures or suture lines. They do not fully close until the 2nd or 3rd year of life. A metopic ridge occurs when the 2 bony plates in the front part of the skull join together too early.
What is Paget's disease of the skull?
Paget's (PAJ-its) disease of bone interferes with your body's normal recycling process, in which new bone tissue gradually replaces old bone tissue. Over time, bones can become fragile and misshapen. The pelvis, skull, spine and legs are most commonly affected.

The cranial ridges, also referred to as exo-cranial ridges or cranial plates are bony plates on the surface of the forehead on many humanoid species. Some species, such as Humans, Vulcans, and the ancient humanoids do not possess visible cranial ridges.
Hemimegalencephaly (HME) is a rare neurological condition in which one-half of the brain, or one side of the brain, is abnormally larger than the other.
What is this? “In almost all cases, a brain tumor will not cause any lumps on the scalp,” says Kathryn Boling, MD, a board certified family medicine practitioner with Mercy Medical Center in Baltimore, MD. “The bones of the skull keep brain tumors from showing up as lumps,” adds Dr.
Bone resorption can also affect the skull: ... bony orbits change their shape and get bigger; the lower jaw gets wider; the nose gets bigger, the tip of the nose droops due to bone changes.
Increased head size may be from any of the following: Benign familial macrocephaly (family tendency toward large head size) Canavan disease (condition that affects how the body breaks down and uses a protein called aspartic acid) Hydrocephalus (buildup of fluid inside the skull that leads to brain swelling)
Macrocephaly is usually a symptom of other conditions. Benign familial macrocephaly is an inherited condition. It happens in families predisposed to having larger heads. Sometimes there is a problem with the brain, such as hydrocephalus or excess fluid.
Children with metopic synostosis have visible symptoms that include one or all of the following: A noticeable ridge running down the middle of the forehead. An overly narrow, triangular shape to the forehead and top of the skull. Eyes that appear too close together.
Trigonocephaly is a congenital condition of premature fusion of the metopic suture (from Greek metopon, "forehead"), leading to a triangular forehead. The merging of the two frontal bones leads to transverse growth restriction and parallel growth expansion.
Unlike plagiocephaly, craniosynostosis is a birth defect. It occurs when the bone plates in the skull fuse earlier than usual. As a result, the skull can no longer grow larger normally. Instead, the skull compensates by growing in other directions, which results in an abnormal head shape.
In the head, the soft spots start to come together and the fontanelle at the back of the head closes at about four months, with the frontal fontanelle closing between 9 to 18 months.
Scaphocephaly is caused by the early fusion of the sagittal suture which runs from front to back at the top of the skull. Early fusion of a suture in infancy is called synostosis and this type is the most common form of craniosynostosis.
Bones can change their shape throughout our life by regulating bone formation and resorption processes, which is often a response to forces which press, pull and twist the skeleton during everyday movements and exercise. The purpose of this shaping is to limit any risk of fracture.
Damage to joint cartilage can lead to arthritis. Changes in the bones of the skull and ear can lead to hearing loss.
Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported.
Suture may begin to fuse by the age of 24. Average Suture closes between the ages of 30 years old and 40 years old.
Non-syndromic bicoronal craniosynostosis is a condition that leads to premature closure of both coronal sutures but is not associated with any syndrome or associated deformities or conditions. Although the majority of bicoronal synostosis is of the syndromic type (Apert, Crouzon, Pfeiffer, Carpenter, etc.)
Because meningiomas tend to grow inward, they commonly cause pressure on the brain or spinal cord. They can also grow outward causing the skull to thicken (hyperostosis).
These tumors can grow slowly or rapidly. Symptoms of chondrosarcomas depend on their location in the skull base and may include headache, ringing in the ears, and problems with vision, hearing, or balance.
The human skull is definitely asymmetrical; this is not a matter of skull bones that differ individually from a symmetrical model, but the skull is asymmetric as a whole (Woo, 1931).
The cranium is documented to grow from birth through adolescence. The standard of practice in primary care is measuring head circumference and plotting growth using curves that stop at 36 months.
Macrocephaly means big head, and it is the name for a condition in which an infant or child has an abnormally large head size. For a doctor to diagnose macrocephaly, the measurement of the head around its widest part needs to be larger than the 98th percentile.
Some amount of brain shrinkage occurs naturally as people age. Other potential causes of brain shrinkage include injury, certain diseases and disorders, infections, and alcohol use. Just as the body ages, so does the brain. But not all brains age the same.
