Background: Pseudocyst of the pinna is a benign, idiopathic, painless, spontaneous dome shaped cystic swelling on the anterior surface of the auricle. It is a difficult condition to treat medically or surgically and a large number of treatment modalities have been described in the literature. Definitive treatment still remains controversial. Aim: To study the effectiveness of cartilage window with buttoning technique in the treatment of pseudocyst of the pinna. Methods: A prospective study at a tertiary care centre for a period of one year, which included 26 patients with diagnosis of pseudocyst pinna. All the patients were treated by excising the small cartilage window and using the buttoning technique for compression and were followed up after one week and one month of surgery. Results: All the 26 cases were completely relieved off the disease at the end of one month and none showed any recurrence. None of our patients had any postoperative complications like perichondritis of pinna or any structural deformities. Conclusion: The surgical treatment of pseudocyst pinna by making a cartilage window with buttoning technique is an excellent for treatment ofpseudocyst pinna.
