PINNA CONDITIONS

Haematoma auris. Trauma to the pinna has caused a haematoma between perichondrium and cartilage. Risk of avascular necrosis of the cartilage or disfiguring fibrosis. © Bruce Black MD

Old haematoma auris. Cartilage necrosis and irregular heavy fibrotic changes have produced a “cauliflower ear” in

an old boxer. © Bruce Black MD

Acute perichondritis secondary to an insect bite. Prompt broad spectrum antibiotic therapy and topical steroid

ointment indicated. © Bruce Black MD

Acute perichondritis. Diffuse painful oedema secondary to minor trauma. Treat promptly to avoid suppuration, abscess

formation and cartilage necrosis. © Bruce Black MD

Past poorly managed perichondritis. The auricular cartilage has necrosed and collapsed. Difficult to correct surgically.

Early allergic otitis externa subsequent to neomycin drop use the previous day. Erythema and serous ooze appearing on the helix. Pruritic. Cease drops, clean, topical steroids. © Bruce Black MD

Allergic otitis externa. Recent use of ciprofloxacin drops. Pruritis, discomfort and serous discharge. Note the

associated skin eruption posterior to the pinna. © Bruce Black MD

Allergic reaction to chloromycetin drops initiated two days previously. Dried serous discharge evident on the helix and

in the conchal bowl. © Bruce Black MD

Allergic otitis externa. Intense pruritis and discomfort. Profuse serous discharge. Secondary to chloromycetin

drops. © Bruce Black MD

Acute allergic otitis externa. Neomycin drop use 4/7 previously. Pruritis, swelling and discomfort. Clean

thoroughly, wet mop, liberal steroid ointment. © Bruce Black MD

Cirofloxacin allergic reaction, subsequent to drop use for chronic otitis.

Ciprofloxacin reaction over the lower pinna, secondary to management of otitis externa. Swollen, erythematous and

pruritic. © Bruce Black MD

Gross iodine hypersensitivity, postoperative case. Use of BIPP (bisthmus, iodoform and paraffin paste) in an open

cavity mastoidectomy. © Bruce Black MD

Neurodermatitis/eczema. Typical erythema and exfoliation at the EAC entrance, secondary to rubbing, scratching.

Heavy smoker, left ear similar. © Bruce Black MD

Habitual trauma to conchal bowl causing eczema. Warn patient re the necessity to desist. Wet thoroughly and remove irritating hard keratin. Apply steroid ointment. © Bruce Black MD

Relapsing polychondritis of the right pinna. The auricle is diffusely swollen and the cartilage floppy, causing fold-over.

Detail of the previous case. Auto-immune cartilaginous reaction. May be fatal if cardiac or respiratory structures are

affected © Bruce Black MD

A large retention cyst in the conchal bowl, occluding the EAC entrance.
