Face and Neck Flashcards
Painful syndrome involving the mandibular joint
Temporomandibular Joint Dysfunction (TMJ)
3 subtypes of Temporomandibular Joint Dysfunction (TMJ)
- Myofascial pain and dysfunction
- MC subtype
- Affects masseter, temporal, pterygoids - Internal derangement
- Dislocation of the articular disc in the glenoid fossa - Osteoarthritis
- Degeneration of the articular cartilage
epidemiology of TMJ
- 31% adults, 11% children
- 1.5x in females
- 18 - 44 y/o
- associated with mood disorders, other psychiatric comorbidities
- increased prevalence with rheumatoid arthritis
- bruxism
cause of TMJ
- Exact cause unknown
- Can be associated with trauma
- Orthodontic treatment
- Arthritis
- Excessive use of joint and muscles of mastication
- Nail biting
- Gum chewing
- Teeth gritting - Psychogenic causes also linked to TMJ
- often have depression, anxiety, stress
- Psychogenic factors thought to exacerbate symptoms, rather than cause them
clinical findings of TMJ
- Joint pain
- Joint noise
- Clicks
- Crepitus - Abnormal mandibular movement
- Masticatory muscle tenderness
- Patients may complain of pain using their jaw, their jaw locking, or their bite not feeling right
- HA - frontal, temporal, occipital
- Dizziness or vertigo that is associated with aural fullness or otalgia
hx of TMJ
- Facial pain -Pain with jaw function, limitation of movement, cracking or popping, jaw muscle fatigue after eating.
- Ear sx - pain, aural fullness, tinnitus, vertigo, hearing loss.
- Pain in the head, neck, shoulder, and upper back
Headaches - Hx of previous TMJ surgery or trauma.
- Hx of arthritis
- “Habits” such as pencil biting, gum chewing, or clenching, gritting or grinding of teeth.
- Bruxism, either night (sleep-related) or daytime (awake).
- Evaluation for depression and anxiety as well as the presence of other chronic pain symptoms
- Sleep quality
PE of TMJ
- Abnormal Jaw Movements
- Palpation for tenderness or crepitus
- Pain with dynamic loading - pt bite down on tongue blade
- Evaluate for bruxism - look for wearing down of teeth
- Evaluate postural asymmetry
assess posture - does pt favor one side? - Neuromuscular exam
- inspect and palpate the muscles of the neck and shoulders
- assess cranial nerves - special consideration for CN V and VII
tx for TMJ
- Joint rest
- To allow muscles of mastication to relax
- Reduce mandibular condyle movement - Avoid chewing gum, biting nails, excessive talking
- Eat a soft diet
- Reduce stress
- Physical therapy
- Exercises include mouth opening and closing in a straight line - Intra-oral devices
- Splints, night guards, bite guards - Botox injections
- Muscle relaxation
- Only temporary relief - 3-4 months
Diagnosis is usually clinical
when to refer for TMJ
Symptoms do not improve after 6 months of joint rest
Progressive difficulty in opening the mouth
Inability to eat a normal diet
Recurrent dislocation of the temporomandibular joint
MC head and neck cancer
SCC
paranasal sinuses, oral cavity, nasopharynx, oropharynx, hypopharynx, and larynx
Tumors of what differ from the more common carcinomas of the head and neck
salivary glands
Tumors of what differ from the more common carcinomas of the head and neck
salivary glands
risk factors of head and neck cancer
- Alcohol, Tobacco, Smokeless tobacco
- Marijuana
- Occupational exposures
- Dry cleaning
- Farming - pesticides
- Construction - asbestos - Nickel refining
- Exposure to textile fibers
- Radiation therapy
- Genetics
- Poor oral hygiene
Viral etiology of head and neck cancer
EBV - Nasopharyngeal cancer
HPV - Oropharynx
HSV
Hep C
HIV
what Dietary factors may contribute to head and neck cancer
Higher incidence with low consumption of fruits and vegetables
