What does "Osteoradionecrosis" mean?
Table of Contents
Osteoradionecrosis (ORN) is a serious condition that can occur after radiation therapy for head and neck cancers. It happens when the bone in the jaw doesn't heal properly after being damaged by radiation. This can lead to pain, infection, and even the loss of parts of the jaw.
Causes
Several factors can increase the risk of developing ORN. These include:
- Receiving high doses of radiation to the jaw.
- Having dental extractions before or after radiation therapy.
- Smoking or having gum disease.
- The location of the cancer, such as in the mouth or throat.
Symptoms
People with ORN may experience:
- Pain in the jaw.
- Swelling or tenderness in the mouth.
- Loose teeth or exposed bone.
- Difficulty opening the mouth.
Diagnosis
ORN is diagnosed through a combination of dental exams and medical history. Imaging tests like X-rays may also be used to assess the condition of the bone.
Treatment
Treatment for ORN often includes:
- Antibiotics to fight infection.
- Surgery to remove damaged bone.
- Dental care to ensure oral hygiene.
- Pain management strategies.
Prevention
To reduce the risk of ORN, it’s important for patients undergoing radiation therapy to:
- Maintain good oral health.
- Have dental issues addressed before starting treatment.
- Follow their healthcare team's advice on care after radiation.
