### Patient: Hi Doctor, I have been experiencing a lot of pain and discomfort in my jaw, especially when I try to chew or yawn.
### Doctor: Based on your symptoms, it seems like you might be suffering from Temporomandibular joint disorder. To confirm the diagnosis, we will have to conduct other diagnostic procedures such as an interview, evaluation, and consultation. Additionally, we will need to carry out ophthalmologic and otologic diagnosis and treatment, as well as diagnostic procedures on your nose, mouth, and pharynx. It might also be necessary to do a Central venous cannula insertion (Central line insertion) to assist in the diagnosis and treatment of the disorder.
