A 25-year-old male patient came to the traumatology. He complains about pain in the right half of his face, limited mouth opening. Objectively: there is a moderate edema and haematoma in the region of the right malar arch. Palpation shows a slightly painful impaction of bone tissue in the region of the right malar arch. The bite isn't disturbed. Amplitude of mouth opening is 1,5 cm. At making an attempt to open the mouth wider the patient feels a mechanical obstacle and pain intensification. What is the most likely diagnosis?
