Question
After not undergoing surgical treatment for a mandibular fracture, a sunken chin and limited mouth opening were observed.
Answer
Based on the patient’s description and the provided information, it is suspected that there may be a mandibular fracture, although treated, there is still difficulty in opening the mouth. It is recommended to go to the hospital for further examination. If the fracture site is stable, consider taking symptomatic anti-inflammatory medication and gradually performing mouth opening exercises to promote recovery.
