Some patients reach adolescence or adulthood with unrepaired oronasal fistulas (open communications between the mouth and nose) and alveolar clefts (bone discontinuity defects in the bone supporting the teeth), even though the primary cleft defect has been repaired.
In patients with bilateral clefts, particularly those with coexisting bilateral alveolar clefts, it is important to stage the lip/ nose and external rhinoplasty procedures separately from the orthognathic procedures so that the vascular supply to the anterior portion of the maxilla (premaxilla) is not jeopardized (24).
This is followed by surgery to reposition the maxilla with rigid fixation, including closure of oronasal fistulas, autogenous bone grafting of the alveolar clefts, and synthetic bone grafting to the maxillary osteotomy sites to stabilize the area and facilitate healing.
