Proboscis lateralis (PL) is a rare congenital craniofacial anomaly and it is represented by rudimentary, tube-like nasal structure measuring 2–3 centimetre (cm) length and generally attaches to medial canthal region. A 22-month-old male patient was referred to our clinic with a PL hanging from the right medial canthus and a coloboma on the medial third of the right lower eyelid. Physical examination revealed that the PL was 4 cm long and 1.5 cm in diameter. There was a blind cavity with dimple at its distal segment. The right side of the nose and the nasal airway was aplastic. Before surgical correction, neuroradiological evaluation should be performed to obtain the characteristics and relationship of the lesion with adjacent structures and associated anomalies Many reconstructive options have been described in the literature, however, these options are insufficient to obtain natural contour and define alar crease, especially. We described the laterally-based skin flap from the medial wall of the left heminose and adapted to the lateral edge of the de-epithelialized skin of PL for defining supra-alar crease.
