From: Difference in the Surgical Outcome of Unilateral Cleft Lip and Palate Patients with and without Pre-Alveolar Bone Graft Orthodontic Treatment

Figure 2

Left upper first and second: the alveolar bone defect was defined.

The anatomic defect requiring alveolar bone grafting was also confirmed with three dimensional facial CT scans. Left upper third: A superiorly based gingival mucoperiosteal flap was raised to explore the alveolar bone defect. Left upper fourth: the palatal mucoperiosteal flap was raised to a level beyond the deepest margin of the alveolar fistula. Left lower first: the nasal floor tissue was completely closed. The bone graft was packed into the defect area. Left lower second and third: complete closure of gingival and palatal wounds.
