We encountered a 7-month-old female and a 15-year-old male with bifid nose which was treated surgically.In the first patient, thick skin with a longitudinal fissure extending along the nasal dorsum was excised in a spindle-shape. Four incisions parallel to the nasal septum were performed, two of which were made along the nasal septum; the other incisions ran lateral to them. Thus, the nasal cartilages were sutured centrally for augmentation. The remaining orbital hypertelorism will require correction by craniofacial surgery in the future.In the second patient, the nasal dorsum was flattened and covering skin was normal. However, a small concavity was detected on the nasal tip. This deformity was easily corrected by augmentation rhinoplasty using a silicone prosthesis.The classification and etiology of a bifid nose are reviewed, and introduce the 'Cleft Numbering System' of Tessier.
