Objective To overcome the difficulties of one-stage secondary alveolar bone grafting for patients with bilateral cleft lip and palate (BCLP) who have a broad alveolar cleft, the value of two-stage alveolar bone grafting was examined. Patients Three patients (2 girls and 1 boy) with BCLP were treated by two-stage alveolar bone grafting. The procedure consisted of a first-stage surgery (mean age 8 year 6 months ± 7.8 months), which consisted of alveolar bone grafting for one side of the BCLP, and second-stage surgery for the contralateral side several months later. For the postoperative assessment, radiographs of the operated site were examined. Results The average amount of implanted bone per operation and per patient was 6.8 ± 1.1 g and 13.7 ± 1.0 g, respectively. Postoperative clinical and radiographic examinations revealed that an appreciable alveolar bone ridge had formed, and there were no major complications. Conclusions Two-stage alveolar bone grafting, which makes it possible to reduce the amount of implanted bone, could be an optional surgical procedure for patients with BCLP and a broad alveolar cleft.

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 septopremaxillary 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.

Objective: To assess the radiographic outcome of secondary alveolar bone grafting in individuals with nonsyndromic unilateral or bilateral cleft lip and palate using cone beam computed tomography. Methods: This prospective study was conducted at the University of California at San Francisco Center for Craniofacial Anomalies on 21 consecutive nonsyndromic complete cleft lip and palate individuals between 8 and 12 years of age who required alveolar bone grafting. Seventeen unilateral and four bilateral cleft lip and palate individuals had preoperative and postoperative cone beam computed tomography scans that were analyzed using Amira 3.1.1 software. Results: The average volume of the preoperative alveolar cleft defect in unilateral cleft lip and palate was 0.61 cm3, and the combined average volume of the right and left alveolar cleft defects in bilateral cleft lip and palate was 0.82 cm3. The average percentage bone fill in both unilateral cleft lip and palate and bilateral cleft lip and palate was 84%. The outcome of alveolar bone grafting was assessed in relation to (1) type of cleft, (2) size of preoperative cleft defect, (3) presence or absence of lateral incisor, (4) root development stage of the maxillary canine on the cleft side, (5) timing, and (6) surgeon. None of these parameters significantly influenced the radiographic outcome of alveolar bone grafting. Conclusions: Secondary alveolar bone grafting of the cleft defect in our center was successful, based on radiographic outcome using cone beam computed tomography scans. Volume rendering using cone beam computed tomography and Amira software is a reproducible and practical method to assess the preoperative alveolar cleft volume and the adequacy of bone fill postoperatively.

Objective To report the surgical outcomes of secondary alveolar bone grafting with premaxillary osteotomy in a single surgeon cohort of complete bilateral cleft lip and palate patients. Design Retrospective review of 44 consecutive patients using hospital notes and radiographs. Setting Single specialist cleft lip and palate center, UK. Patients Consecutive patients with complete bilateral cleft lip and palate who were being treated with secondary alveolar bone grafting incorporating premaxillary osteotomy. Outcome Measures Assessment of success of bone graft by Kindelan score; canine eruption; closure of fistulae and assessment of morbidity. Results Between January 6, 2000, and August 8, 2013, 44 patients with complete BCLP underwent secondary ABG with a premaxillary osteotomy as a one-stage procedure. The mean follow-up was 7.3 years (range 1.4 to 14.6). Eighty-five percent of ABGs were successful (a Kindelan score of 1 or 2), and canine eruption was 89%. Failure of the ABG occurred in 7%. Fistulae recurrence rate was 11%, all of which were asymptomatic. No premaxillae were devitalized. Conclusion Incorporating a premaxillary osteotomy into the secondary ABG surgical protocol can be a safe technique that gives excellent surgical exposure for fistula repair.

Objective To determine if secondary alveolar bone grafting (SABG) timing in patients with cleft lip and palate (CLP) influences the future need for additional maxillary advancement procedures, particularly Le Fort I osteotomy with rigid external distraction (RED). Design Retrospective cohort study. Groups were separated by SABG timing: early mixed dentition (ages 68 years) or late mixed dentition (ages 9-11 years). The criterion for RED was negative overjet ≥8 mm, and sufficient dental development for RED. Setting Single tertiary care institution. Patients Patients with CLP that underwent SABG from 2010 to 2015. Exclusion criteria included syndromic conditions, SABG surgery at age >12 years, current age <12 years, and <2 years follow-up. 104 patients were included. Main outcome measures The number of RED candidates and treated patients. Results There was no statistical difference in the number of RED candidates ( P  =  .0718) nor treated patients ( P  =  .2716) based on SABG timing; stratification by laterality was also insignificant. Early SABG is associated with higher odds of being a RED candidate (pooled, unilateral, bilateral) and treated patient (pooled and unilateral); however, there were no statistically significant associations between SABG timing and the number of RED candidates and treated patients as determined by logistic regression models. Conclusion There is no statistically significant association between SABG timing and the odds of being a RED candidate or treated patient. Future prospective studies are recommended to assess the relationship between SABG timing and maxillary growth in patients with CLP.

Secondary Alveolar Bone Grafting

Objective To assess if a 4-point, radiographically based scale could be used between operators to reliably assess the success of secondary alveolar bone grafting. Design The study was retrospective with the clinicians blind to patient identity. Radiographs were examined twice by two clinicians with 1 week between assessments. Setting The research was carried out in a hospital-based orthodontic/oral and maxillofacial unit. Patients All patients who had secondary alveolar bone grafting in this unit between February 1992 and March 1995 were included In this study. There were 38 patients with a total of 48 grafted sites. Interventions The bone graft site was radiographed following orthodontic expansion prior to grafting. The radiograph was repeated postoperatively at a mean of 4 months after surgery. Main Outcome Measure The degree of bony fill in the cleft area was assessed using a 4-point scale: Grade 1 >75% bony fill; Grade 2 50–75% bony fill; Grade 3 < 50% bony fill; Grade 4 no complete bony bridge. Results Overall, 50% of grafts achieved grade 1, 23% were grade 2, 22% grade 3, and 5% grade 4. Levels of intra- and inter-observer agreement were highly variable (.33 to .72 kappa statistic). Conclusions The 4-point scale described could be used to assess the success of autogenous secondary alveolar bone grafting. It showed moderate to substantial intra-observer agreement, and fair-to-moderate inter-observer agreement.
