Abstract:
Nonsyndromic alar clefts are rare and they range from a small notch to variable size of clefts of the nasal ala. Usually they are restricted to the alar region, but other minor anomalies such as midline nasal sinuses and small midline or "northbound" clefts can be present. To date all reported cases of nonsyndromic alar clefts have been sporadic. Here we report on five new cases of isolated and nonsyndromic alar clefts.
