TMJ Pathology in Professional Musicians: A look beyond the risk factors. Physiological Neuromuscular Rehabilitation. First and second phase. Case Report.

Several articles and studies cite the prevalence of TMJ dysfunction in violinists and violists, especially by prolonged flexion of the head and shoulder, posture necessary to keep the violin in position. Studies also report that the incidence of TMJ dysfunction in musicians is similar to the general population.

Professional musicians require many hours of training and improvement that involve complicated movements, fast and repetitive actions with over use of the hands, fingers, arms and head.

Most articles report anxiety about professional performance and increased muscle tension, but few do a particular study of the state of the anatomical structures of the cases studied.

1 postura inicial frontalA 45-year-old female patient referred by her physiotherapist consults with complaints of headache, pain in the cervical and scapular region, muscular contractures in the mandible.

The patient also reports mandibular displacement when playing the violin and pain in both temporomandibular joints.

2 postura inicial lateralThe patient also reports clicks in both temporomandibular joints and occasionally the sensation of clogged ears.

Frequent pain in the spine and both shoulders.

At that time the patient had already consulted physiotherapists, rheumatologists, psychiatrists and psychologists.

3 OCLUSÃO INICIALImage of the patient’s habitual occlusion on the day of the appointment.

4 OCLUSAIS INICIAISUpper and lower occlusal views of the patient on the day of the consultation.

5 PANORAMICA 1Initial panoramic radiograph of the patient before treatment.

Teeth 18, 28 included.

Wear on the incisal and occlusal faces of the teeth present.

Prosthetic device 25 to 27 (26 pontic)

Horizontal resorption of alveolar ridges.

6 LAMINOGRAFIA INICIALPatient’s TMJ initial laminography before treatment

In the maximum opening position, observe the anterior angulation of the articular processes. Structural modification of the mandibular condylar process as one of the sequels of traumatism in infancy.

The patient reports a trauma in early childhood, a knock on the head while playing on a slide.

7 TELEPERFILLateral radiograph and patient profile before treatment. Patient in habitual occlusion.

8 FRONTALFrontal radiography of the patient in habitual occlusion before treatment.

9 C7Lateral and cervical radiograph of the patient in habitual occlusion before treatment.

At this time, the patient performed a CT scan of the cervical spine

In the report there is rectification of cervical lordosis.

Degenerative discopathy in C5-C6, observing reduction of the height of the disc space and osteophytic proliferations reactional. At this level the disc-osteophyte bar is identified that touches and distorts the ventral face of the dural sac.

There is no stenosis of the central vertebral canal.

Neural foramina with amplitude within the limits of normality.

Mild signs of uncovertebral arthrosis C5 and C6.

Relationship C1-C2 maintained.

Symmetric paravertebral regions.

10 eletromiog dinamica inicialDynamic electromyographic record in patient’s habitual occlusion before treatment. Note the minimal activation of the right and left masseter muscles in maximal intercuspation and the high activation of the right and left temporal muscles.

The masseter muscles are the most powerful muscles of the stomatognathic system, the temporal muscles even being elevating muscles have to have an equal and preferably smaller activation than the masseter muscles.

11 cineciog 1Initial cineciographic record of the patient.

Three-dimensional view of the mandibular displacement.

The record shows mandible opening, closing and speed when the patient makes these movements. The patient shows a 47 mm opening and a right deflection of 3.9 mm

Note a significant  loss of velocity in the middle of the mandibular closure.

The articular disc is displaced anteriorly, with reduction in open-mouth maneuvers. (open mouth images not included in the post)

Note the posterior compression in this section.

Primary objective has to be the three-dimensional decompression of the mandibular condyle.

21 FRONT DIR E ESQMRI: frontal slice of right and left temporomandibular joints, closed mouth in habitual occlusion before treatment.

The frontal slice of the right temporomandibular joint shows a loss of joint space, especially in the region of the external lateral pole of the joint. Both frontal images show a decrease in joint space.

Slight medial disc deviation.

21A registro inicial para o DIOTo correctly evaluate the maxillomandibular relationship we should begin to consider the physiological rest mandible position.

Physiological rest is a concept applicable to all the muscles of the body.

The stomatognathic musculature is no exception.

The patient’s masticatory muscles were deprogrammed electronically and a new physiological neuromuscular position at rest was recorded.

The patient has a pathological free space of 5.8 mm, already discounting the two physiological mm of a healthy free space.

The patient also presented a 2.1 mm mandibular retroposition

22 oclussao com o DIOWith these data we constructed a DIO (intraoral device), to maintain the three-dimensional recorded position. This device must be electromyographically tested to objectively measure the patient.

It is logical that the report of the patient’s symptomatology is important, but the surface electromyography shows in an objective way if the muscular function improved, worsened or did not modify.

22A eletromiografia com o DIOElectromyographic record with DIO (intraoral device) in physiological neuromuscular position.

Note the higher recruitment of motor units in the masseter muscles that previously showed very little activity.

22A Registro cinesiográfico para controlar o DIO em posição neurofisiológicaCineciographic record for the DIO (intraoral device) control in physiological neuromuscular position as the device is changed or recalibrated.

In the first phase the intraoral devices are recalibrated and / or changed according to each specific case as the jaw, muscles and TMJ improve.

Each case IS UNIQUE. There are cases where the TMJ structures are so damaged that the objectives outlined will have limitations dictated by the initial diagnosis.

These limitations refer not only to the structures of the temporomandibular joint, but also to the patient’s systemic condition.

22B 2 Registro cinesiográfico para controlar o DIO em posição neurofisiológicaAnother cineciographical record to control the Dio in a physiological neuromuscular position as the device is changed or recalibrated.

With the jaw in a physiological neuromuscular position the physiotherapist colleague worked the rest of the muscle chains, using global manual techniques, always taking into account the individuality of the patient. This work in a patient with degenerative discopathies should be maintained

MRI: Comparison of the frontal slice of the RIGHT TMJ, closed mouth, before the physiological neuromuscular treatment, and of the same RIGHT TMJ after the FIRST PHASE.

Note the decompression of the temporomandibular joint, especially in the lateral pole.

The patient did not report any more symptomatology related to the TMJ. Bioinstrumentation also objectively showed an improvement in neuromuscular function.

It was decided to start the SECOND PHASE of the treatment to remove the DIO (intraoral device), maintaining the physiological neuromuscular occlusion.

For this we used a three-dimensional orthodontic, where the teeth are erupted to the new neurophysiological position.

55 ORTO 1In the second phase, in this case the three-dimensional orthodontics the patient is monitored and deprogrammed electronically, and often the device is recalibrated, to maintain the position obtained in the first phase.

Patient testimony:

What made me look for the treatment were recurrent headaches, frequent

(weekly) and intense, which lasted, on average, 2 days, affecting my productivity

at work as well as leisure hours.

The pain did not subside with common analgesics, requiring strong medication, which, in turn, only softened the pain a little.

Today, after the treatment, I can say that only very rarely do I suffer from these pains, greatly improving the quality of life, besides the posture.
