Study Notes
Extra Oral Examination - Self Assessment Questions
- Purpose of Extra Oral Examination: To identify undiagnosed conditions, including malignancies.
- Areas to Examine (EO Exam): Upper face (forehead, eyes, cheeks, upper nose), lower face (lower nose, lips, chin), checking for symmetry, lesions, bruising, swelling, and excessive sweating.
- Importance of Examination: Asymmetry, unexplained lesions, bruising, swelling, or excessive sweating may indicate underlying systemic diseases or potential malignancies. Lesions on the lips or mouth corners could be herpes (contagious) or angular cheilitis (fungal). Squamous cell carcinoma can present as an ulcer, blister, or red/white patch.
- Examination Method (Q3): Palpating (feeling) for swelling, tenderness, and enlarged lymph glands.
- Lymphadenopathy: Disease of the lymph glands, often presenting as swelling and tenderness.
- Optimal Operator Position (Q4): Patient standing behind, and relaxed. The head should be slightly forward, and the chin should be level. Use fingertips to examine lymph nodes (both sides) and TMJ using gentle pressure.
- Lymph Node Locations (Q5): Preauricular (anterior to earlobe), postauricular (posterior to the ear), occipital (behind the ear), parotid (region of gland), retropharyngeal (tonsillar region), submandibular (posterior area), submental (anterior area), anterior cervical, posterior cervical, and supraclavicular (superior region of shoulder.)
- Healthy Lymph Node Characteristics (Q6): Small (pea-size), not tender, and usually mobile.
TMJ Examination (Q8)
- Key Components: Tenderness, pain, deviation to one side, clicking, and limited opening.
Patient Questions for Examination Abnormalities (Q9)
- History is Essential: The patient should be asked about any acute, chronic, systemic, or oral conditions they are experiencing.
- Symptom Inquiry: Questions to consider include duration of the problem, pain, frequency of ulcers, biting or burning sensations, and teeth clenching/grinding habits.
