Supernumerary nostril with complete unilateral cleft lip: a case report and review.

The supernumerary nostril is an extremely rare congenital anomaly of duplication. A review of the literature shows that only 17 cases have been reported in the world. The supernumerary nostril in association with facial clefting is even more rare, with only three cases reported so far. We are reporting a case of supernumerary nostril in association with complete unilateral cleft lip without cleft palate, which happens to be the first case of its kind to be reported. Most supernumerary nostrils are situated superior to the normal nostrils and very few of them are situated at the same level or below the normal nostrils. In this case, the supernumerary nostril was placed lateral to the normal nostril.
