)

Know the aetiology of head and neck swellings

Know the investigation used in the management process

What Is DDx ?

the distinguishing of a disease or condition from others presenting with similar signs and symptoms

Slide5

Head and neck swellings

Numerous masses

may develop in the head and neck, and these may also be

termed

swellings,

growths, tumors, lumps, and bumps

.

Although some swellings are cancerous ,

many are not

.

However, it is important to investigate if any abnormal bump or swelling persists for

more than two weeks

.

Slide6

what type of structures found in the head and neck region

Lymph nodes

Salivary glands

Fat tissue

Blood vessels

Thyroid and parathyroid glands

Thymus

Potential spaces (fascia spaces)

Slide7

DDx of head swellings

Inflammatory

Lymphadenopathy (inflammatory or metastatic )(most common)

Infections (viral or bacterial )

Trauma

Cysts (Dermoid , epidermoid , sebaceous and lipoma)

Bone diseases

Paget’s disease

Cherubism

Benign ( fibrous dysplasia , ossifying fibroma )

Slide13

Symptoms Associated with Head & Neck Lumps

Change in the voice including hoarseness that

persists for more than two weeks

Growth in the mouth

Swollen tongue

       Blood in the saliva or phlegm

  Swallowing problems

Slide15

History

Slide16

Clinical examination

Slide17

Summary of examination

Examination of some masses / swelling may allow a physician to determine their cause based on location, size, and consistency.

In other cases, however, additional tests may be required.

Changes in the skin – It is important to examine changes in the skin that could indicate basal cell carcinoma, squamous cell cancer, and malignant melanoma.

Persistent Ear Pain or ear pain while swallowing may be a symptom of infection or a growth in the throat.

Slide20

Radiographic Investigation of the Head and Neck Masses

MRI – Magnetic Resonance Imaging can clearly highlight soft tissue pathologies better than the C.T. Scan.It uses a magnetic field rather than x-rays (radiation).

Slide21

Radiographic Investigation of the Head and Neck Masses

CT SCAN – Computed tomography is less accurate than M.R.I for the soft tissue examination very useful to locate bony tumors and their dimensions and extensions.C.T with contrast is used to enhance the visibility of abnormal tissue during examination.

Slide22

Radiographic Investigation of the Head and Neck Masses

PET (Positron Emission Tomography) and SPECT (Single Photon Emission Tomography) are useful after diagnosis to help determine the grade of a tumor or to distinguish between cancerous and dead or scar tissue. They involve injection with a radioactive tracer.

Slide23

Biopsy

F.N.A.C – Fine Needle Aspiration Biopsy is Safe Rapid Inexpensive Presurgical planning Avoids open biopsy

Slide24

Treatment modalities

Medical

Surgical

Radiotherapy
