There’s info in the Newbies Guide Section- Common symptoms & what might cause them; here’s some info for you:
‘Symptoms are divided into two groups. The first group of symptoms, are characterized by pain located in the areas where the fifth, seventh, eighth, ninth and tenth cranial nerves are distributed and occurs in most of the cases after tonsillectomy which may have been performed many years earlier.’ (Dolan, Mullen, Papyoanou).
‘Pain following tonsillectomy is presumably created by stretching or compressing the nerve or nerve endings of cranial nerves V, VII, VIII, IX, or X in the tonsillar fossa either during healing (scar tissue) or shortly thereafter.’ (Langlais RP, Miles DA, Van Dis ML. Elongated and mineralized stylohyoid ligament complex: A proposed classification and report of a case of Eagle’s syndrome, 1986).’
And: ‘Trigeminal Nerve branches (CN V) are also in this region- Eagles Syndrome is listed as a possible cause of Trigeminal Neuralgia (TN)/ Non-Neuropathic Facial Pain . TN causes two types of symptoms- Type1 is sudden intense, electric- shock like, stabbing, or burning pains which can also cause muscle spasms , and Type 2 is a constant aching, boring or burning pain .’
‘The Trigeminal Nerve has 3 branches, which carry sensations of pain and touch. The branches go along the lower jaw, into the lower teeth and the temple region; the upper jaw, teeth, cheek, part of the nose and just below the eye; and across the scalp, forehead, and the eye. The motor branches of the Trigeminal Nerve also innervate muscles for chewing, and sensory branches go to the mucous membranes of the eyes and nose, and symptoms of damage can be dry eyes and mouth. (http://calder.med.miami.edu/pointis/tbiprov/MEDICINE/sense1.html1 ).’
‘I have seen research showing that it is the lower branch (Mandibular) of the Trigeminal Nerve which is most commonly affected by Eagle’s Syndrome. In one documented case, the TN pain the patient was suffering was eased by a partial removal of the styloid, but then returned. The patient later had a full styloidectomy, and again the pain eased, before returning years later, and with more severe TN. The researchers state ‘This suggests that trigeminal neuralgia often exists in a prodromal state characterized by dull constant jaw pain, particularly if there is a distal structural defect to exacerbate the pain. The underlying abnormality that eventually causes classical trigeminal neuralgia may be present in an early form. This early form might not be capable of causing facial pain on its own, but might sensitize distal trigeminal nerve branches to local compression or stretching. It might sensitize the alveolar nerves to pain in the jaw from dental problems. (or in our case from an elongated styloid process and scar tissue.) Eagle syndrome… may also be associated with pain in a trigeminal V3 distribution.’
