What could cause a forehead dent?

A forehead dent can have various causes, some of which are:

Trauma: A direct blow or trauma to the forehead, such as from a car accident or sports injury, can cause a depression or dent in the forehead.

Congenital Deformities: Some individuals may be born with a naturally sunken or dented forehead, which is considered a congenital deformity. This can be due to abnormal skull development during fetal development.

Enlarged Frontal Sinus: The frontal sinus is a hollow space located behind the forehead. In some cases, this sinus can grow larger than usual, leading to a visible depression in the forehead.

Craniosynostosis: A rare condition in which certain sutures in the skull close prematurely, resulting in abnormal head shape and sometimes causing a dented forehead.

Meningoencephalocele: A neural tube defect involving the protrusion of brain and meninges through an opening in the skull, which can create a visible dent on the forehead.

Post-Surgical Depression: Surgeries that involve removing bone or tissue from the forehead or nasal area can create an apparent depression or dent.

Aging: Natural aging processes may result in some loss of facial volume, including the forehead, causing a dent-like appearance.

Certain Medical Conditions: Rarely, some medical conditions or genetic syndromes may present with facial features that include a sunken or dented forehead.

If you or someone you know has a sudden or unexplained forehead dent, it's advisable to seek medical attention to determine the exact cause and appropriate treatment plan.
