Disease Of Pinna Flashcards
What is perichondritis?
Infection & inflammation of perichondrium
What is the appearance of the ear in perichondritis?
Cartilage: congested
Lobule: spared
What is the cause of perichondritis?
Injury (ex. Piercing) leading to infection
What is the m/c organism that causes perichondritis?
Pseudomonas
What is the treatment for perichondritis?
Oral ciprofloxacin
What is hematoma?
Collection of blood btwn perichondrium & cartilage
What is etiopathogenesis of hematoma?
- Trauma
- Perichondrium rubs on cartilage
- Leakage of blood
- Hematoma
What is the management for hematoma?
- Aspiration
- Contour dressing where button are stitched on both sides of pinna to prevent recurrence
What is cauliflower ear?
It’s the complication of repeated hematoma causing an irregular shape
What is the pathogenesis of cauliflower ears?
Cartilage proliferation/chondroblast invasion in hematoma
What is the treatment for cauliflower ears?
Plastic surgery for cosmetic purposes
What is cause of avulsion of pinna?
Trauma
What is the management for avulsion of pinna?
Wash -> debride -> reattach (micro vascular anastomosis)
What is the management for avulsion of pinna if the skin has already detached?
- Debridement
- Reattach cartilage to amputated stump
- Bury cartilage into retroauricular skin pocket
What is chondrodermatitis nodularis helicis/winkler’s disease?
Painful nodule on cartilaginous pinna
What is the cause for chondrodermatitis nodularis helicis/winkler’s disease?
Pressure and temperature changes due to less padding/insulation
Common site of chondrodermatitis nodularis helicis/winkler’s disease
Helix/anti-helix
What is the management for chondrodermatitis nodularis helicis/winkler’s disease?
- Relieve pressure by cushioning during sleep
- Excision + biopsy (to rule out carcinoma)
What is keloid?
Abnormal proliferation of fibroblasts following abnormal wound healing due to iatrogenic trauma
What are the features of keloid?
- firm/rubbery
- extends beyond margins of scar
- high chance of recurrence
What is the first line management for keloids?
Local intralesional steroids
What is the treatment for large keloids?
Excision + intralesional steroids
What is the treatment for multiple keloids?
Radiotherapy/cryotherapy post-incision (to prevent recurrence)
What is the appearance of a sebaceous cyst?
Soft, compressible with puncta
