Unusual alveolar clefts: report of cases.

Four cases with atypical alveolar clefts are presented. In the first, a sixteen-year-old boy had an alveolar cleft in the region of the left lateral incisor, a submucous cleft palate and a narrowed left nostril. The alveolar cleft was corrected with a bone graft. In the second case, an eleven-month-old boy had an alveolar cleft in the region of the normal lateral labial frenulum between the left canine and the first premolar, and an ordinary microform of cleft lip on the right side. A six-month-old boy has a complete cleft lip, alveolus and palate on the left side in the third case, and bilateral alveolar clefts in the region between the canine and the first premolar both in the maxilla and the mandible. In case four, an eight-month-old boy has an alveolar cleft in the region of the normal lateral labial frenulum between the right canine and first premolar. Lip and palate were fused normally.
