A novel negative pressure drainage treatment of auricular pseudocyst

Pseudocyst of the auricle is a benign cystic lesions of the ear. A variety of methods have been proposed priorly with different treatment effects. Although aggressive treatments may have good results, we aimed to introduce a less invasive method that also yield optimal cosmetic outcome. From August 2019 to April 2020, a total of 32 patients with pseudocyst of the auricle were treated with a novel negative pressure drainage method. The treatment has performed successfully in all patients. Only 2 patients experienced negative pressure drainage device detachment, and recovered smoothly after reinstallment. Patients were followed up for an average period of 3 months. The appearance of the auricle was recovered excellent in all patients. There were no postoperative complications or episodes of recurrence during the follow-up period. Considering the excellent cosmetic outcome and free of recurrence, we would recommend our negative pressure drainage method as a first-line treatment for all patients with auricular pseudocyst. •It would be preferable if treating auricular pseudocyst with less invasive method could also yield optimal cosmetic outcomes.•Removing the auricular cartilage is not necessary to avoid recurrence.•Our negative pressure drainage treatment is not affected by the uneven surface of the auricle to achieve balanced pressure.•The continuous drainage of the cyst fluid is the key of our treatment.•We would recommend our negative pressure drainage method as a first-line treatment of auricular pseudocyst.
