Temporomandibular joint (TMJ) complex is one of the most complex joints, which connects the mandible to the skull. This kind of joint system has the ability to perform complex and bilateral movements. Due to complex anatomy, there is a need for a thorough investigation to find the correct etiology of TMJ disorders. For a thorough investigation, starting from clinical examination to imaging strategies should be performed meticulously. Radiographic imaging is an important element in the correct diagnosis. Because of the anatomic complexity of the temporomandibular joint and its proximity to the temporal bone, mastoid air cells, and auditory structures, imaging of the joint structures should also be investigated. Therefore, careful clinical and radiological examinations are essential in the evaluation of TMJ. The manuscript examines the potential use and technique of ultrasonography (USG) in fine-needle aspiration biopsy and intra-articular sodium hyaluronate/steroid injection.
