How can fractures of the maxillary best be diagnosed?

  1. CT scan

  2. MRI

  3. Clinical examination and A-P radiograph of the skull

  4. Ultrasound

The correct answer is: Clinical examination and A-P radiograph of the skull

Fractures of the maxillary bone are best diagnosed through a combination of clinical examination and an A-P radiograph of the skull. This is because a CT scan is not necessary for simple fractures and has higher radiation exposure, while an MRI is not typically used for diagnosis of bone fractures. Ultrasound is also not recommended for diagnosing fractures of the maxillary bone as it is unable to penetrate through bone tissue. Therefore, clinical examination and an A-P radiograph are the most effective and appropriate methods for diagnosing fractures of the maxillary bone.
