Differential Diagnosis for a 47-year-old Male with Suspected Mandible Fracture

Single Most Likely Diagnosis

  • Delayed Union or Nonunion of Mandible Fracture: This is the most likely diagnosis given the patient's history of trauma 2 months prior, initial negative X-rays, and current symptoms of occlusion being off. The absence of ongoing pain or trismus does not rule out a fracture, especially if it is a non-displaced or minimally displaced fracture that has not healed properly.

Other Likely Diagnoses

  • Mandibular Fracture Missed on Initial X-rays: It's possible that the initial X-rays missed a fracture, especially if it was non-displaced or if the X-rays were not of high quality. The patient's current symptoms could be indicative of a fracture that was present but not diagnosed initially.
  • Occlusal Dysfunction: The patient's complaint of the occlusion being off could be due to occlusal dysfunction, which may not be related to a fracture but rather to other dental issues such as tooth wear, misaligned teeth, or temporomandibular joint (TMJ) disorders.
  • TMJ Disorder: TMJ disorders can cause symptoms similar to those of a mandible fracture, including pain and difficulty with occlusion. However, the absence of pain in this case makes this diagnosis less likely.

Do Not Miss Diagnoses

  • Pathological Fracture: Although less likely, a pathological fracture due to an underlying condition such as osteonecrosis of the jaw, metastatic disease, or multiple myeloma must be considered. These conditions can weaken the bone and lead to fractures with minimal trauma.
  • Infection: Osteomyelitis or other infections of the mandible could present with similar symptoms and must be ruled out, especially if there are signs of infection such as fever, swelling, or drainage.

Rare Diagnoses

  • Fibrous Dysplasia: A rare condition where normal bone is replaced with fibrous tissue, leading to weakened bones that are prone to fractures.
  • Giant Cell Tumor: A rare, benign tumor that can occur in the jaw and lead to fractures or other symptoms similar to those described.
  • Eagle Syndrome: A rare condition where an elongated styloid process or calcified stylohyoid ligament can cause facial pain and other symptoms that might mimic those of a mandible fracture.
