A patient has pain over the left pre-auricular area, this patient can open approximately 45 mm and has a “pop-and-click” in the joint area. The MOST likely diagnosis is
a. myofacials pain dysfunction syndrome
b. internal derangement with reduction
c. auriculotemporal syndrome
d. coronoid hyperplasia

I think the answer is B

B

Derangement with reduction is diagnosed by observing the jaw when the mouth is opened. When it is opened > 10 mm, a click or pop is heard or a catch is felt, caused by the head of the condyle popping back onto the disk. The condyle remains in this position during further opening. Usually, another click is heard during closing when the condyle slips over the posterior rim of the disk and the disk is pulled forward.

For MPDS
Symptoms include soreness when the masticatory muscles are palpated and often pain and limitation of mouth opening. Nocturnal bruxism may lead to headache that is more severe on wakening and that gradually improves during the day. Symptoms and headache may worsen during the day if bruxism continues during the day. The jaw deviates when the mouth opens but usually not as suddenly or always at the same point of opening as it does in internal joint derangement. With gentle pressure, the examiner can open the mouth another 1 to 3 mm beyond unaided maximum opening.

And due to click and pop in the question that is why I picked choice B as derangement because there is a characteristic click and POp and the symptoms dont get better unlike MPDS where they improve over the day unless the patient is grinds his teeth.
Hope this helps.
