Clinical Trial Summary
reconstruction of alveolar cleft with autogenous bone after elevation of mucoperiosteal flap
and suturing of nasal floor and palatal flap
Description:
gingival mucoperiosteal flaps are designed along the cleft margins and elevated medial and
lateral mucoperiosteal flaps are generated from the cleft and the gingival sulcus of the
teeth. To obtain adequate mobility of the posterior flap, the flap must be extended to the
first or the second molar and back-cut up to the buccal sulcus while taking care not to
injure the alveolar bone covering the roots of the teeth. These flaps are raised up to and
around the piriform aperture, and then are separated from the nasal mucosa the palatal
mucoperiosteal flaps along the cleft margins are then elevated from the palate. After
complete exposure of all the bony clefts, the nasal lining of the nostril floor is
approximated and sutured, and the palatal flaps are then turned back and sutured to make a
soft-tissue pocket. Grafting of the defect is accomplished with cortical bone only from the
chin the cortical shelf is prepared to be two layers perpendicular to each other the first
one is parallel to the nasal floor and second one is continuous with buccal cortex of
alveolar ridge then cancellous bone will be packed under these shelves and be compressed into
the cleft defect to maximize the number of osteo-competent cells and the osteoid material per
unit graft volume. When packing bone particles, it is better to create the maxilla and
alveolar ridges and elevate the depressed nostril by appropriately supporting the nasal base
and aligning the symmetry. The rest can then be covered with gingival mucoperiosteal flaps
through tension-free transposition
