A Mandibular fracture is a common type of facial fracture. It is a break in the mandible, or lower jaw. The mandible is the second most commonly fractured facial bone, after the nose.

Causes[edit | edit source]

Mandibular fractures are often caused by physical trauma, such as vehicle accidents, falls, and sports injuries. They can also be caused by violence or pathological fractures due to diseases such as osteoporosis or cancer.

Symptoms[edit | edit source]

Symptoms of a mandibular fracture can include pain, swelling, bruising, and difficulty opening the mouth. Other symptoms can include numbness in the lower lip, a change in the way the teeth fit together, and an inability to fully open or close the mouth.

Diagnosis[edit | edit source]

Diagnosis of a mandibular fracture is typically made through a combination of physical examination and imaging tests, such as X-rays or a CT scan. The doctor will look for signs of injury, such as swelling, bruising, and changes in the alignment of the teeth.

Treatment[edit | edit source]

Treatment for a mandibular fracture depends on the severity of the fracture and the patient's overall health. Treatment options can include surgery, immobilization of the jaw, and pain management. In some cases, a dietary modification may be necessary.
