During the past twelve years, twenty-one patients with nasal vestibular cyst were observed at the Yokohama City University Hospital and Tokyo Senbai Hospital. Of these, one case of bilateral nasal vestibular cysts was reported. The patient was a 41-year-old male diagnosed by physical and X-ray examinations. The removed cysts were diagnosed as nasal vestibular cysts on both sides. Klestadt's theory that the cyst arises from the embryonic cleft in the facial region is supported by the histological and clinical findings in this study.
