Ans:B. Pseudocyst of pinna.
Pseudocyst of pinna
- Benign cystic swelling resulting from intracartilaginous accumulation of fluid.
- The scaphoid fossa, triangular fossa of the antihelix, and the cymba concha are typically involved.
- Various terms for this condition are endochondral pseudocyst, intracartilaginous auricular seroma cyst, cystic chondromalacia, and benign idiopathic cystic chondromalacia.
- Males are commonly affected and the mean age of presentation is 35-40 years.
The majority of the pseudocysts are unilateral lesions.
- Usually these cysts are asymptomatic but occasionally, minor discomfort and mild inflammatory signs may be present.
- The size of the cyst ranges from 1 to 5 cm in diameter and contains viscous straw-yellow fluid while sometimes a clear pale yellow may be encountered.
- The etiology of this condition is unknown but repeated minor injuries may be responsible .
- The ideal treatment is the preservation of the anatomical architecture of the pinna and prevention of recurrence.
- Incisional drainage, followed by chemical obliteration(by intralesional corticosteroid) or mechanical obliteration such as pressure dressing with button bolsters and compression suture therapy.
- Resection of the anterior cartilaginous leaflet of the pseudocysts with repositioning of the overlying skin flap or the so-called deroofing technique followed by buttoning
