Ear Anatomy, Embryo, Congenital, Recon Flashcards
What is cauliflower ear and how do you manage it?
= subperichondrial hematoma caused by blunt trauma shearing force separating cartilage from perichondrium
- Early (7days): Excise fibroneocartilage and bolster 7days
What is suppurative chondritis and how do you manage it?
= infection of cartilage, (Pseudomonas>Staph) same as chondritis but with FLUCTUANCE and induration, occurs 2’ burned ear.
- leave eschar as biologic dressing and apply sulfamylon cream BID to prevent suppurative chondritis
- If present, INCISION AND DRAINAGE, treat with cephalosporin/penicillin + ciprofloxacin IV
What are the options for reconstructing Helical rim?
1- Antia-Buch: Rim<2cm defect. Incision along helical sulcus through anterior skin and cartilage, leaving intact posterior auricular skin. May get more advancement with V-Y at helical crus
2- Auricular cartilage graft + local skin advancement or flap
3- Tubed flap (2stage)
What are the options for reconstructing Upper 1/3?
1- Ortichea Conchal chondrocutaneous rotation flap
2- Antia-Buch
3- Post-auricular skin flap and rib cartilage or contralat concha
4- Pre-auricular banner flap and cartilage graft
What are the options for reconstructing Middle 1/3?
1- Dieffenbach: retro-auricular skin advancement to cover cartilage graft and at 2nd stage divided to recreate tube + sulcus. Donor gets FTSG
2- Converse Tunnel procedure: defect line drawn on mastoid skin, and incised along defect margin, graft placed within mastoid skin and sutured to auricle. Divide after 8-12wks and donor gets FTSG
3- Antia-Buch
4- Direct excision with crescents and wedges (Tanzer)
5- Tubed flap
What are the options for reconstructing Lobule?
1- Neolobule
2- Pardue technique
