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.
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.
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.
本文介绍一种结合两阶段牙槽骨植骨的上颌前部复位手术技术，用于矫正双侧唇腭裂（BCLP）患者的上颌前部畸形。本文还报告了两名接受这种手术治疗的BCLP患者。
手术通常在患者8至14岁时进行。在手术的第一阶段，选择更易接近鼻中隔 - 上颌前部交界处的一侧，进行上颌前部截骨术和单侧牙槽骨植骨。在第一阶段手术大约4至12个月后，进行对侧牙槽骨植骨。
我们发现这种手术方法非常有效，因为它确保了上颌前部的血液供应，并将手术失败的可能性降至最低。此外，它能广泛暴露上颌前部骨表面，便于充分的骨桥接，并允许牙齿进行正畸移动。
