Study Notes
Extra Oral Examination
- Aim: To provide understanding of the extra oral examination's clinical relevance.
Intended Learning Outcomes
- Explain the relevance and importance of extra oral patient examination.
- Identify significant areas related to an extra oral examination.
- Explore techniques and observations needed for an effective extra oral examination.
What is Extra Oral Examination?
- Part of the general initial patient assessment.
- Carried out to identify undisclosed or undiagnosed conditions, including malignancies, endocrine disorders, and indications of cardiovascular risk.
Areas of Examination
- Upper Face: Forehead, eyes, cheeks/cheekbones, upper part of nose
- Lower Face: Lower part of nose, lips, chin, general facial symmetry
Neck Examination
- Palpation: Feel for swelling, tenderness, and any abnormalities in lymph nodes.
- Lymphadenopathy: Lymph node disease often presents as swollen and tender lymph nodes.
Lymph Node Anatomy
- Diagram shows lymph nodes in the head and neck.
- Specific lymph node groups are listed: Posterior auricular, Occipital, Superficial cervical, Deep cervical, Supraclavicular, Preauricular, Parotid, Tonsillar, Submental, Submandibular, etc.
What Should Lymph Nodes Feel Like?
- Normal lymph nodes are small (pea-sized), not tender, and mobile.
- Abnormal lymph nodes are fixed and often tender.
- If abnormality detected, note size, location, consistency, and diagram.
- Swelling and tenderness due to infection.
How to Perform a Lymph Node Examination
- Stand behind the patient; this is ideal.
- Ensure patient is relaxed.
- Head should be slightly forward, chin not tipped upward.
- Use finger pads in an on/off motion.
Temporomandibular Joint (TMJ)
- Formed by the mandible and temporal bone.
- Composed of capsules and ligaments.
- Responsible for jaw movement (eating, talking, etc.)
- A frequently used joint, common problems involve pain and difficulty opening.
Common Causes of TMJ Pain and Dysfunction
- Teeth grinding (Bruxism): Often caused by stress.
- Pain and stiffness on opening, headaches, neck aches, and other intra-oral problems are possible symptoms.
TMJ Examination
- Palpate both sides to assess for: tenderness, pain, deviation, clicking.
- Ask patient to open and close the mouth.
- Examine both sides simultaneously using finger tips and gentle pressure.
Facial Symmetry
- Assess facial symmetry, noting any deviations from the "normal".
- Significant asymmetries need to be noted and discussed with the patient.
- Causes can include previous trauma/surgery, CVA, infections, neural paralysis etc.
- Look for unexpected swelling, bruising, pallor, and excessive sweating.
Other Important Considerations
- Examine the eyes for any unusual features.
- Evaluate the lips for dryness, chapping, or signs of cracking (angular cheilitis).
- Be alert for possible cold sores or malignant lesions.
- List the possible conditions from slides 33-34.
- Conduct further research.
Summary
- Thorough examination includes the face/lips/eyes/general appearance.
- Detailed lymph node examination, along with TMJ examination.
- Patient history and details related to current issues are essential.
- Note all important observations meticulously.
