Outer Ear Growths
list |
1. CYSTS (bump)
-Sebaceous -Preauricular -Dermoid 2. TUMORS -Benign -Malignant -Neoplasms -Carcinomas |
|
|
Sebaceous Cyst
|
Form when excretions accumulate from an obstructed sebaceous gland duct.
|
|
|
Preauricular Cyst
Preauricular Sinuses |
Congenital malformation
-cyst = bump on the pinna -sinus = indentation on pinna May indicate inner ear problems |
|
|
Dermoid Cyst
|
Developmental cysts that contain hair, epithelium and glands
|
|
|
Treatment of Cysts
|
-Surgical excision
-Surgical dissection (enlarged, infected cyst) -Electric current treatment |
|
|
Neoplasm =
Carcinoma = |
"new growth"
"cancerous growth" |
|
|
Benign Tumors
-definition -examples |
-Tumor doesn't spread to distant sites
-Doesn't affect surrounding tissue -Cosmetic issue mostly -Keloids (extra scar tissue), angiomas, cysts, neurofibromas, warts, exostoses, osteomas, gland tumors |
|
|
Malignant Tumors
|
Tumor spreads to distant sites
Adjacent tissue is destructed. -Squamous cell carcinoma (most common) -Basal cell carcinoma (worst) -malignant melanoma -sarcoma (malignant bone growth) |
|
|
neurofibromas
|
fiberous benign tumor on a nerve
|
|
|
Exostoses
|
Vascularized bony growth from cold water exposure.
-multiple growths in circular pattern |
|
|
Benign Tumor Treatment
|
Exostoses
- Hemangiomas -Early observation; will usually get smaller with time. Chondromas/Osteomas -Surgical removal if it's in the way. |
|
|
Malignant Tumor Treatment
|
-Wide local excision and skin grafting to prevent metastasizing.
-Remove entire EAC if tumor's in bony portion (low cure rate) -Chemotherapy, Radiation |
