1. Haematoma of the auricle. It is collection of blood between the auricular cartilage and its perichondrium. Often it is the result of blunt trauma seen in boxers, wrestlers and rugby players. Extravasated blood may clot and then organize, resulting in a typical deformity called Cauliflower ear . If haematoma gets infected, severe perichondritis may set in. 2. Lacerations They are repaired as early as possible. The perichondrium is stitched with absorbable sutures. Special care is taken to prevent stripping of perichondrium from cartilage for fear of avascular necrosis. Skin is closed with fine nonabsorbable sutures. Broad-spectrum antibiotics are given for 1 week. 3. Perichondritis It results from infection secondary to lacerations, haematoma or surgical incisions. It can also result from extension of infection from diffuse otitis externa or a furuncle of the meatus. Pseudomonas and mixed flora are the common pathogens. 4.acute otitis externa 5. otomycosis 6.myringitis bullosa 7.malignant otitis externa #entlectures #ENT #Medicos
