Dr Shapira Response: The trigeminal nerve supplies approximately 50% of all input to the brain. Because the MRI scan was normal does not mean the pain is not from or mediated by the trigeminal nerve. This can include TM Joint problems, TMD, Myofascial Pain, otalgia (trigeminal). All of these problems are mediated by the trigeminal nerve which is why neuromuscular dentistry is such an effective approach to chronic pain of the head and neck.
Sphenopalatine Ganglion Blocks can address the autonomic connections of the trimeninal nerve. It is usually a simplification to just call something a "TMJ" problem because there are usually multiple concerns based on symptomatology.
I normally spend an hour or more reviewing the history of patients with pain. The patient gave me no information about the SYMPTOMS that caused her to seek treatment. An accurate chronological history is an essential element in understanding how to approach a problem to bring relief. An MRI will show organic problems but are rarely the diagnostic approach to chronic pain. It is helpful in that it rules out tumors, growths, etc.
An examination of the craniomandibular and cervical musculature is incredibly important in anyone with headaches, facial pain, migraines, trgeminal pain, ear or jaw pain. Evaluation of the TM Joints and jaw motion is also very important.
The Neuromuscular Diagnostic work-up includes EMG evaluation of the jaw and/or neck muscles, Computerized scans of jaw movement and function, Sonography is sometimes used as well.
