2. Anatomy

3. Anatomical Considerations
Prominent Landmarks
Triangles of the Neck
Regional Anatomy
Lymph Node Levels
Carotid Bulb
Transverse Process of C1

5. Historical Points.
Age:
Up to 15yrs (pediatrics)  more than 90% benign
16 to 40 (young adult)
More than 40yrs (older adults)  80% neoplasm  80% of
them malignant (secondary>>primary)
Time course
immunodeficiency
Prior trauma
Travel, Irradiation, Surgery
Associated symptoms  fever, dysphagia, weight loss, otalgia,
hearing loss, respiratory difficulties
Perform a FULL head and neck examination

6. Neck Masses:
Epidemiology
Adult neck masses are 90% malignant
Pediatric neck masses are rarely malignant.
Most common neck mass in children is an
enlarged reactive lymph node 2ry to
bacterial/viral infections
Almost 50% of all 2 Y/O children have
palpable normal cervical lymph nodes

10. Identification of Neck Masses On
Basis Of Their Location
Anterior Neck Swellings
Lateral Neck Swellings
Posterior Neck Swellings
Diffuse Neck Swellings
Identification of Neck Masses
On Basis of their location:
