A magnetic resonance (MRI) was prescribed to assess the disc-condyle relationship as the possible source of limitation in mouth opening and to gather some pictorial evaluation of the presence of joint effusion (Figure 1).

A diagnosis of TMJ intermittent locking on the left side was thus performed, and given the difficulties to stabilize clinical symptoms and mouth opening with the usual conservative approaches, the patient was planned for a surgical removal of the TMJ disc with concurrent HAM positioning (Figure 2).
MRI at the five-month follow-up. Closed (a) and open mouth position (b) showing the HAM patch. The HAM patch covers the condyle head; the translation is improved.

Five months after surgery, a new MRI was performed (Figure 3). The images showed the physiological excursion of the TMJ condyle during mouth opening (Figure 3(b)).
