If a patient has a deformed head, it may be caused by the following reasons: 1. It may be caused by serious head trauma, such as when the patient suffers a direct violent blow to the head, which may lead to a serious fracture due to serious injury. The fracture healing process may result in a deformed healing situation, which may lead to a change in the shape of the patient’s head. 2. It may be caused by the patient’s bad habits, such as the patient lying on one side for a long time or using only one side of the teeth for chewing, which may lead to a deformation of the patient’s head over time. 3. A similar situation may occur when the patient develops acromegaly, deformational osteitis and a series of other diseases.
