Temporomandibular joint disorders are a common cause of chronic musculoskeletal pain worldwide. Among these, internal disc derangement is the most frequent type of disorder. Internal derangement is defined as an abnormal positional and functional relationship between the disc and articulating surfaces. Common clinical symptoms include pain and clicking.Imaging plays a key role in diagnosing temporomandibular joint disorders. It is important for the radiologist to detect early imaging signs of internal derangement, thereby avoiding the evolution of this condition to degenerative joint disease. The aim of this article is to familiarise the reader with the spectrum of imaging findings that are encountered at different stages of the disease.

Spontaneous herniation of temporomandibular joint into the external auditory canal through the foramen of Huschke is a very rare condition. We describe a case of spontaneous temporomandibular joint herniation in a 35-year-old male, who presented with otorrhea and aural fullness. The herniation was repaired using collagen mesh. A literature review of all the previous reported cases of spontaneous temporomandibular joint was done to study the presenting clinical features and the method of surgical repair.

The complete dislocation of the orbital contents into the maxillary antrum as a result of trauma is an extremely rare event and requires immediate exploration and repositioning of the globe with reconstruction of the orbital floor. We present the case of a 10-year-old male who sustained trauma to the orbit and was initially suspected to have developed auto-evisceration. He underwent successful exploration and reconstruction of orbital floor with remarkable improvement.
