Anatomy of The Tempormandibular Joint
Controlling Pathology
–Needing to control the cause of the pathology is still the primary concern
– Inflammatory changes within the synovial fluid secondary to trauma infection or disease creates cartilage and bony breakdown
• Controlling inflammatory responses is key
Controlling Pathology
» Acute inflammation is characterized as lasting minutes, hours, up to a few days
» Chronic inflammation is characterized as lasting longer and non remitting for the period of time concerned
» Inflammation consists of 2 main components • Vascular changes… increased blood flow to area • Increased vascular permeability… to cellular
components
• Leukocyte or Neutrophil increase as first responders
• Proteins leak out of vessels (Exudate) to produce swelling
• Chemical mediators of pain released from cellular response to produce pain

Pathogenesis of Pain and Inflammatory Responses
• Knowledge about the pathogenesis on a molecular level of disorders of the TMJ has been improved in recent years giving a possibility to use these data for the evidence based treatment. Inflammation mainly affects the posterior disc attachement (Holmlund & Axelsson, 1996; Leibur et al., 2010). Several inflammatory mediators play an important role in the pathogenesis of TMJ diseases as tumor necrosis factor ┙ (TNF┙), interleukin-1┚ (IL-1┚), prostaglandin E2 (PGE2), leukotrien B4 (LkB4 ), matrix metalloproteinases (MMPs), serotonin- 5- hydroxytryptamine (5-HT), (Alstergren et al., 1999; Voog et al., 2003b). MMPs are responsible for the metabolism of extracellular matrix, being an early marker to determine TMJ arthritis. High level of MMP-3 has been determined in the synovial fluid in TMJ osteoarthritis patients (Kamada et al., 2000). Serotonin, mediator of pain and inflammation, is produced in the enterocromaffin cells of the gastrointestinal mucosa and absorbed by platelets. It is produced also in the synovial membrane and is present in the synovial fluid and in blood in case of rheumatoid arthritis and is involved in the mediation of TMJ pain in systemic inflammatory joint diseases (Alstergren & Kopp, 1997; Voog et al., 2000).
Pathogenesis of Degenerative TMJ
• “Based on recent findings, models of degenerative TMJ disease predict that mechanical loads trigger a cascade of molecular events leading to disease in susceptible individuals. These events involve the production or release of free radicals, cytokines, fatty acid catabolites, neuropeptides, and matrix-degrading enzymes.”
Stephen B. Milam Odontology(2005) 93:7-15
Pathophysiology of TMJ Dysfunction
»Creates inflammatory response and release of chemical mediators of pain
• Generation of highly reactive molecules (free radicals) in response to mechanical stimulation, ultimately creating adhesions through oxidation-reduction reactions (Milam 2005 Odontology)

Pathophysiology of TMJ Dysfunction
1. Intracapsular dysfunction
– Macrotrauma/Microtrauma
• Mechanical dysfunction of the disc
– Creates inflammatory response and release of chemical mediators of pain
» Bradykinin, leukotriene B4, prostaglandin E2, and substance P levels influence success rates in arthrocentesis procedures OMFS 2007 Feb;65(2):242-7 Kaneyama K, Segami N, Sato J, Fujimura K, Nagao T, Yoshimura H.
Arthridities
• Osteoarthritis – Chronic disease process in which degeneration and
loss of articular cartilage occur together with new bone formation at the joint surfaces and margins, leading to pain and deformity
– Results in reduction of proteoglycan content in cartilage, leading to reduced resiliency and deterioration
– The body is unable to repair articular cartilage, so the underlying bone response by remodeling and forming bone spurs (osteophytes)
Arthridities
– Rheumatoid Arthritis
• Autoimmune disease which attacks the joints via the synovial linings of the joints creating inflammatory reactions and release of degradative enzymes ultimately breaking down articular cartilage causing bony deformation
– Psoriatic Arthritis
• Autoimmune disease
– Gouty Arthritis

TMJ Degenerative Processes
Pathophysiology of TMJ Dysfunction
• Once the source of the pathology is determined what is done to treat it – Start off conservatively
• Must control the cause of the pathology – Reduce trauma/inflammation
– Non surgical management • Splint therapy
• Medicinal therapy
• Control parafunctional habits
• Control psychological/social influences
Pathophysiology of TMJ Dysfunction
• What to do if conservative treatment is unsuccessful
• Categorize internal joint disc pathology
– Wilkes Classification
• Wilkes Class I-V
• Most research is or should be done with this classification to standardize research results

Wilkes Classification of Internal Joint Derangements
• Class I: Painless clicking. No restricted motion. Slight forward displacement of disk.
• Class II: Occasional painful clicking, intermittent locking, headaches. Slight forward displacement of disk, beginning deformity, and slight thickening of posterior edge.
Wilkes Classification of Internal Joint Derangements
• Class III: Frequent pain, joint tenderness, headaches, locking, restricted motion, and painful chewing. Anterior disk displacement with significant deformity/prolapse of disk. Class IV: Chronic pain, headaches, and restricted motion. Increase in severity from III with early to moderate degenerative changes, flattening of eminence, deformed condylar head, sclerosis.
Wilkes Classification of Internal Joint Derangements
• Class V: Variable pain, joint crepitus, and painful function. Disk perforation, filling defects, gross anatomic deformity of disk and hard tissues with degenerative arthritic changes.

Disc Dispacement
• Dr. Joe Van Sickels published a paper in the 80’s regarding disc position and it’s importance in outcomes – Study included 100 patients
– Pre op imaging disclosed ADD without reduction– closed locks Wilkes Class III
– Arthrotomy procedure performed with distal wedge and sutured disc back into position
– After 6 months re imaging revealed 60% of discs were again ADD without reduction yet they still had increase MIO and decreased pain compared to pre-op

Arthrocentesis
• Purpose number one
– By overfilling superior joint space allows for separation of the suction cup effect and will separate some less fibrous adhesion
Arthrocentesis
• Purpose number two
– Irrigate the superior joint space and flush out all synovial fluid contents which contain chemical mediators of pain, allowing the body to replenish with new synovial fluid void of these substances

Holmlund-Hellsing Line
• A line is drawn from the lateral canthus to the most posterior and central point on the tragus
The posterior point of entry is located along the canthotragal line 10 mm from
the middle of the tragus and 2 mm below the canthotragal line. This is the approximate area of maximum concavity of the glenoid fossa
(Point A)
Holmlund-Hellsing Line
• The anterior point of entry is placed 10 mm further along the canthotragal line and 10 mm below it (Point B)
• Always remember the distance from skin to the center of the joint space is about 25 mm
Arthrocentesis/Arthroscopic Techniques
• Arthrocentesis is actually the beginning steps of Arthroscopic Surgery
• Multiple techniques (S. Tozoglu et al. 2010 British Journal OMS) – Arthrocentesis
• Single needle (Guarda-Nardini)(Rahal)
• Double needle…. Both posterior to eminence (Alkan)
• Double needle…. One needle posterior, one needle anterior (Nitzen et al.)
• All techniques utilize 2-300cc
of fluid (usually LR)

Arthrocentesis/Arthroscopic Techniques
• Arthroscopic Technique – Multiple approaches depending on which part of the
joint you are interested in looking at • Superior posterolateral (3) • Superior anterolateral (1) • Endaural (2) “A review of techniques of lysis and lavage of the TMJ” (S. Tozoglu et al. 2010 Bristish Journal of OMS)
Techniques of Arthroscopic Surgery
• Most common is the superior postero-lateral approach providing visualization of the majority of the superior joint space
• The superior antero-lateral approach allows for visualization of the antero-superior joint compartment
• The Endaural approach is for visualization of the posterior superior joint space and medial and lateral paradiscal troughs

Disc Repositioning and Arthroplsaty
• TMJ dysfunction is a common condition an estimated 12-87% of the American population has reported at least one sign of TMJ Dysfunction.
• Anterior +/- medial displacement of the articular disc is the most common condition causing joint dysfunction.

• Flynn B, Brown DT, Lapp TH. Oral Surg Oral Med Oral Pathol 1990: 70 372-380
• Disc displacement can result in
• Decreased Joint Space • Clicking/Popping/Crepitation • Arthritis • Condylar resorption • Jaw deformities • Malocclusion • Compression of the bi-laminar tissue

• Chronic disc displacement can lead to • Deformation of the disc • Loss of flexibility • Loss of vascularization of the disc • Breakdown of the fibrocartilagenous covering of
the condyle • Perforation of the disc
Wilkes CH. NW Dent 1978: 57: 287-290
– All changes of chronic disc displacement are manifested clinically as progressively worsening jaw function and pain
• Annandale first described surgical repositioning of the TMJ disc in 1887.
• It was not until 1978 when Wilkes used arthrography that disc repositioning became an accepted surgical technique.

Extensive Bone/Implant interface on both the shaft and arch, mineralized bone has grown toward the suture and resulted in a bone gap small than the diameter of the anchor shaft. Fields RT, Wolford. J Oral Maxillofac Surg 2001:59:1402-1406
Pre-operative considerations for placement of Mitek implants
• MRI should be taken preoperatively to evaluate the condition of the disc.
• Surgical intervention should occur within the first 4 years of symptom onset to prevent permanate decrease in joint space.

• Adequate release of the anterior, lateral and sometimes medial attachments of the articular disc are usually necessary to allow passive repositioning.
• Control the occlusion in the post-surgery phase to avoid overloading the joints.
• If the disc shows severe degeneration with bony changes on the condylar head, success of Mitek implant drops from the 90th percentile to the 60th percentile.
• 52 Mitek implants were placed over the last 2 years with follow up of at least 4 months
• Mean pre-surgery VAS score 6.1 where post-surgery the mean was 2.4
• Mean pre-surgery MIO was 38.1 where the mean post-surgery value was 40.9

• The use of Mitek anchors – 1) Provides controlled mandibular translation while
preventing mandibular condylar dislocation
– 2) Relatively straight forward technique with predictable results with decreased pain and increased MIO
– 3) Short term results (range 4 months to 2 years) show no failures however the longevity of this technique is unknown
– 4) Superior and Inferior joint space is maintained which appears to be important for allowing patients to return to normal function

Condylar Resorption
Definition: • Head of condyle resorbs partially or completely
– Results in: • Loss of vertical dimension of condyle
• Often creates occlusal and musculoskeletal instability
• Dento-facial deformities
• TMJ Dysfunction
• Pain
Causes of Condylar Resorption: • Local factors
– Internal Derangement, osteoarthritis, avascular necrosis, traumatic injuries, Bruxism, ICR
• Systemic Factors – Rheumatoid arthritis, scleroderma, SLE, Ankylosing Spondylitis,
Hormones, Steroids, Systemic and Autoimmune illness

37
Causes of Condylar Resorption
Pathophysiology of Condylar Resorption:
• Results from dysfunctional articular remodeling due to :
– Excessive or sustained physical stress to the TMJ articular structures that exceeds the normal adaptive capacity (Occlusal therapy, Internal derangement, parafunctional habits, Macrotrauma, Unstable occlusion), or..
– Decreased adaptive capacity of the articulating structure of the joint (Rheumatoid arthritis, scleroderma, SLE, Ankylosing Spondylitis, Age, Hyperparathyroidism, Corticosteroid therapy, Hormones such as Estrogen and Prolactin)

Idiopathic Condylar Resorption
Also Known As:
• Cheerleaders’ syndrome
• Idiopathic condylossi
• Progessive Condylar Resporption
• Condylar Atrophy
• Predilection:
• Female 9:1
• Onset usually age 10 – 40
– Often During pubertal growth spurt
Unstable Occlusion as Etiology
Morphologic associations: • Class II skeletal and occlusal relationship • High occlusal plane angle • High mandibular plane angle Suggested Etiologies: • Excessive force on condyle
– Parafunctional habits – Orthognathic surgery – Orthodontics – Trauma
• Poor bone quality • Decreased blood supply to condyle
Hormones as an Etiology
Increased Estrogen Receptor Theory
• Estradiol 17b deficency
– Study by Gunnerson
• 26 females started on EE (ethynl estradiol) – Oral Contraceptive
• 19 patients noted occlusal changes within 1 month
• Symptomatic TMJ joints have 5 times more Estrogen receptors
• Upregulation of receptors likely to be caused by estradiol 17b deficency
![Page 39: ARTHROCENTESIS AND ARTHROSCOPY · Patients Diagnosed with TMJ Disease: When is Surgery Indicated ? PRINCIPLES AND PRACTICE OF TMJ PROCEDURES: ARTHROCENTESIS AND ARTHROSCOPY . 6/25/2014](https://reader033.fdocuments.in/reader033/viewer/2022052409/605e65ac44493b44880d9793/html5/thumbnails/39.jpg)
6/25/2014
39
Etiology
Increased Estrogen Receptor Theory • Exaggerated estrogen response to excessive joint loading
– Trauma – Parafuntional habits – Orthodontic treatment – Orthognathic surgery
• High estrogen response leads to – Synovial tissue hyperplasia – Damages to ligamentous structures – Anterior disc displacement – Destructive hyperplastic synovial tissues surrounds condyle – Resorption of the condyle
• Rate of about 1.5mm a year
Diagnosis
Patient History • Worsening occlusion • Increased TMJ symptoms
– 25% had no TMJ issues according to Wolford.
• Worsening of class II relationship • Anterior Open Bite • Unilateral or Bilateral • Rule out systemic causes Imaging • Panograph, Lateral cephalometic, CBCT, CT, MRI
• Anteriorly displaced disk • Small resorbing condyle • Poorly defined cortex • Decreased vertical height of ramus
Diagnosis
Active vs. Inactive:
• Technetium isotope bone scan
– Technetium-99m methylene diphosphonate (99mTc-MDP)
– Kaban & Colleagues set normal values of mandibular uptake
• Active Condylar Resorption – 2 standard deviations above normal uptake
– Serial Bone scans confirm when resorption has become inactive

Conclusion
• Type of Surgical Intervention for ICR should be considered case by case based upon:
– Patient’s History
– Active vs inactive resorption
– Ability to salvage Disc
– Amount of condylar resorption
– Patient Preference
• Appropriate Surgical Treatment should then be initiated
