Auricular pseudocysts are rare lesions that present as an asymptomatic cyst
ic swelling of the anterior surface of the auricle, particularly the antihe
lix. Typically, the pseudocysts contain viscous straw-yellow fluid similar
in appearance to olive oil; however, a clear pale yellow serous transudate
may also be encountered. Various therapeutic approaches have been used with
variable success. We describe a simple small vacuum device called the Chul
alongkorn University vacuum device, which was developed in our center. The
device can be easily made anywhere by any surgeon. We report the outcome in
17 patients treated by means of needle aspiration plus application of the
Chulalongkorn University vacuum device for 5 days. A complete resolution of
the lesion was obtained in 15 (88.2%) patients. Because the procedure is s
afe and effective and does not require an operating room setting, it may be
accepted as an option in the treatment of auricular pseudocysts.
