    Abstract:
    OBJECTIVE: This paper introduces a surgical technique for premaxillary repositioning in combination with two-stage alveolar bone grafting for the correction of the premaxillary deformity of patients with bilateral cleft lip and palate (BCLP). The paper also reports on two patients with BCLP who underwent this surgical management. SURGICAL PROCEDURE: The operation is usually performed when the patient is 8 to 14 years of age. In the first stage of surgery, the side more accessible to the septo-premaxillary junction is selected, and an osteotomy of the premaxilla and unilateral alveolar bone grafting are performed. Approximately 4 to 12 months after the first stage of surgery, contralateral alveolar bone grafting is carried out. CONCLUSION: We have found that this surgical procedure is highly effective, because it ensures the blood supply to the premaxilla and minimizes the potential for surgical failure. Moreover, it affords wide exposure of the premaxillary bone surface, facilitating sufficient boney bridging and allowing for orthodontic tooth movement.
