Jaw Injuries

What are they?

Jaw injuries refer to abnormal growths, infectious or inflammatory diseases affecting the jawbone and mandible. These lesions can originate from a number of factors, including developmental abnormalities, infections, trauma or neoplastic processes. They may manifest as:

  1. Cysts: Cysts are like 'fluid-filled sacs' that can develop in the jawbone. The most common types of jaw cysts include radicular cysts, dentigerous cysts and odontogenic keratocysts. They can cause swelling in the jaw, pain or changes in the bite and can lead to bone destruction if left untreated.
  2. Tumours: Jaw tumours can be benign or malignant. Benign tumours, such as ameloblastomas, odontogenic fibromas or giant cell tumours, originate in the tissues of the jaw and tend to grow slowly. Malignant tumours, such as pavement cell carcinoma or osteosarcoma, require rapid referral to a referral cancer hospital.
  3. Osteomyelitis: Osteomyelitis is a bacterial infection that affects the bone. It can occur following dental infections, trauma or poor oral hygiene. Symptoms include jaw pain, swelling, fever and pus drainage. Timely treatment is crucial to prevent the spread of infection and further damage to the bones.
  4. Osteonecrosis: Osteonecrosis, also known as avascular necrosis, refers to the death of bone tissue due to insufficient blood supply. Medications such as bisphosphonates or certain cancer treatments such as radiotherapy or chemotherapy can increase the risk. Osteonecrosis of the jaw can cause pain, exposed bone and increased susceptibility to infection.



Diagnosis of jaw injuries requires a thorough evaluation by an oral and facial surgeon. The diagnostic process may include:

  1. Medical history and clinical examination: Your healthcare professional will review your medical history and perform a full clinical examination, including palpation of the jaw, assessment of dental health and evaluation of any associated symptoms.
  2. Imaging: Radiographs, dental cone beam computed tomography (CBCT) or other advanced imaging techniques may be used to visualise the jaw and identify the presence, location and extent of the lesion. Additional imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) may be required for further assessment.
  3. Biopsy: A biopsy may be performed to obtain a tissue sample for microscopic examination. This helps to determine the nature of the lesion (benign or malignant) and to guide appropriate treatment planning.


Treatment of jaw injuries depends on the specific diagnosis, the nature of the injury and its impact on oral health and function. Surgical intervention is often necessary and may include:

  1. Enucleation or excision of the cyst: Surgical removal of the cystic lesion and surrounding affected tissue is usually performed. This procedure aims to remove the cyst and prevent recurrence, while preserving as much healthy jawbone as possible.
  2. Resection of the tumour: Depending on the nature and extent of the tumour, surgical removal may involve a segmental resection (removal of a portion of the jawbone) or a complete resection (removal of the entire affected segment of the jawbone). Reconstruction techniques, such as bone grafts or implant-supported prostheses, may be necessary for functional and aesthetic restoration.
  3. Treatment of osteomyelitis: Treatment of osteomyelitis involves complete debridement (removal of infected tissue) and irrigation of the affected area. In severe cases, surgery may be required to remove the affected bone. Antibiotics and supportive care are often prescribed to help healing and prevent recurrence.
  4. Treatment of osteonecrosis: Treatment of osteonecrosis involves addressing the underlying cause and controlling symptoms. This may involve removal of necrotic bone fragments, antibiotics, oral rinses, pain control and close monitoring of the disease.
