The purpose of the TMD clinic is to diagnose and treat patients with Temporomandibular Disorders. The patients typically present with one or more of the following signs or symptoms:
- Peri-auricular pain
 - Limitation or deviation of mandibular movement
 - Noises associated with the temporomandibular joint[s]
 
In order to avoid inappropriate referrals, the following criteria apply for acceptance onto the assessment clinic:
Patients with peri-auricular pain:
- Should have been assessed by a clinician in an ENT department in order to eliminate disorders of the auditory apparatus
 - Who give a history of trauma or fracture should have been seen in a unit of Oral Maxillofacial Surgery
 - Who have a rapid reduction in mouth opening must have been seen in a unit of Oral Maxillofacial Surgery.
 
Patients who have a limitation or deviation of mandibular movement:
- A rapid reduction in mouth opening and peri-auricular pain must have been seen in a unit of Oral Maxillofacial surgery
 - A recent history of trauma and limitation of mouth opening must have been seen in a unit of Oral Maxillofacial surgery
 - Subsequent to dental therapy when an inferior dental alveolar block injection was used should reviewed by their dentist for two weeks in the first instance
 - Associated with facial swelling or erupting teeth must have been seen in a unit of Oral Maxillofacial Surgery
 
Noises associated with the temporomandibular joint[s]:
- Patients with clicking temporomandibular joint which are painless and never lock rarely require any intervention; in the rare event that the patient is perturbed by these symptoms, referral maybe justified
 - Patients who have peri-auricular noises associated with hearing or balances disturbances must be seen in first instance by a clinician in an ENT department to eliminate disorders of the auditory apparatus
 - Patients whose sole complaint is tinnitus are NOT accepted onto the TMD clinic.
 
In addition to the above:
- Patients undergoing treatment or supervision for behavioural, psychological or psychiatric disorders may be referred only if supported by the consulting physician’s approval
 - Patients with arthritides affecting the temporomandibular joints will only be seen with the agreement of their rheumatologist
 - Patients with suspected or diagnosed neuromuscular / neurological conditions [dyskinesia, or altered perception of senses] should be referred in the first instance to the appropriate clinician
 - Patients who have been discharged after a course of treatment in the TMD clinic may need review. In these cases the patients’ GDP / GMP will be invited to re-refer the patient.
 
Discharge of patients from TMD Clinic:
- Some patients will self discharge by non attendance to the clinic
 - The majority of patients will be discharged at end of treatment
 - Some patients will be discharged at the end of a ‘finished consultant episode’. These patients may need to be re-referred back to the clinic after a period of review in primary care
 - Some patients’ treatment will prove to be unsuccessful, in which case a patient’s best interest will be served by discharge from the clinic together with suggestion for appropriate further referral
