Background: The aim of this study was to investigate whether a complementary Cone-Beam Computed Tomography (CBCT) in patients with Cleft Lip and Palate (CLP) after alveolar bone-grafting to clefts gave substantial additional information, and particularly whether such new information had any implications for the further care of the patients. Methods: Seventeen children, with complete CLP, 10 unilateral and seven bilateral clefts, in all 24 clefts, were evaluated six months after secondary alveolar bone-grafting with two-dimensional intra-oral radiographs complemented with CBCT. The mean age at bone-grafting was 8.8 years. Three different examiners evaluated the radiographic documentation. Results: The mean pre-operative cleft width was 5.8mm. In 15 of the 24 clefts the same interpretation was made on both two-dimensional radiographs and CBCT. In the remaining nine clefts, CBCT added important information to the treatment decision. Conclusions: For the evaluation six months post-operatively of the success of alveolar bone-grafting to clefts, the two-dimensional radiograph should be complemented with CBCT unless the two-dimensional radiograph without doubt reveals open residual cleft and clinical findings indicate graft failure.

Objective: To investigate the effect that alveolar bone grafting (ABG) around 6 years of age has on facial growth by assessing craniofacial growth outcomes. Design: Retrospective cohort study. Setting: North American cleft centers. Participants: A total of 33 children with complete unilateral cleft lip and palate who were consecutively treated with secondary ABG around 6 years of age were compared to 148 participants from 4 centers with late secondary ABG. Methods: Preorthodontic standardized lateral cephalometric radiographs were analyzed and traced according to the Americleft Study protocol. Sixteen angular and 2 proportional measurements were performed. The outcomes of all ABG were assessed using the Standardized Way to Assess Graft scale. Measurement means from the study center (SC) were compared to 4 North American centers using analysis of variance and Welch modified t tests, and P < .05 was considered statistically significant. Results: For the SC, the mean age (SD) at the time of bone graft was 5.85 (0.71) years and the mean age at the time of the lateral cephalogram was 13.4 (1.8) years. The sagittal maxillary prominence of the SC was comparable to the 4 other centers. The mean SNA (78.1 [4.3]) for the SC was significantly higher compared to one center that used primary bone grafting ( P = .03). The soft tissue mean ANB (3.52 [4.09]) for the SC was significantly lower compared to 3 of the centers. Conclusions: Early secondary ABG around 6 years of age did not result in reduced midface projection as assessed by SNA and thus did not compromise anterior maxillary growth.

This study was intended to evaluate the relationship between secondary alveolar bone grafting (SABG) timing and the alveolar volume in patients with unilateral cleft lip and palate (UCLP). The material consisted of CTs of 35 patients (17 males, 18 females) with UCLP who underwent a one-stage primary cleft repair at a mean age of 8.4 months and SABG at different timings ranges of 1.8–18.8 years. The mean age at CT was 17.2 years. The relative coefficient (Ꞷ) which was independent from factors such as individual maxillary size, gender or age at the CT was introduced in order to compare volumes of the cleft-side in relation to the non-cleft-side alveolus. Pearson correlation coefficient r between Ꞷ coefficient and SABG timing was weak negative (r = −0.34, p = 0.045). The multiple regression analysis implied that the dependent variable-Ꞷ coefficient was associated with independent variables (cleft repair and SABG timings and age at CT) with r2 = 0.228. Only patient’s age at SABG explained the dependent variable (p = 0.003). The study cautiously indicates a tendency to larger alveolar volume following earlier timing of SABG. Nevertheless, the further research on a larger group of patients should be performed before formulating any clinical indications.

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 the rate of revision alveolar bone grafting (ABG) in patients with cleft lip and palate (CLP) before and after the introduction of postoperative computed tomography (CT). Design: Retrospective case–control study analyzing the incidence of revision ABG in patients with and without postoperative CT scans for graft success evaluation. Setting: Academic tertiary care pediatric hospital. Patients: Eighty-seven patients with CLP or cleft lip and alveolus treated with autologous iliac crest bone grafting for alveolar clefts over a 10-year period (January 2009 to March 2019) with minimum 6-month follow-up. Fifty patients had postoperative CT evaluation; 37 did not. Interventions: Postoperative CT to determine ABG success, versus standard clinical examination and 2-dimensional radiographs. Main Outcome Measures: Requirement for revision ABG, defined as failure of the original graft by clinical or radiographic examination. Results: Fifty-eight percent of patients underwent a postoperative CT scan at median interval of 10 months after surgery. Patients with postoperative CT evaluation had a 44% rate of revision ABG (22/50) for inadequate graft take, compared to 5% (2/37) in patients without postoperative CT ( P < .001; 95% CT, 31%-58% in the CT group, 1%-16% in the non-CT group). Conclusions: Computed tomography evaluation after ABG is associated with a significantly increased revision rate for inadequate graft take. The presence of a secondary palatal fistula at the time of original ABG is not associated with revision requirement. Lack of standardized dental and orthodontic records complicates the study of ABG outcomes and presents an area for systems-based improvement.

ABSTRACT Objectives: To describe qualitatively and quantitatively the directions and magnitudes of rotations of permanent maxillary central incisors and first molars in the mixed dentition in repaired complete unilateral cleft lip and palate (UCLP) and study their associations with absence of teeth in their vicinity. Materials and Methods: Dental casts and orthodontic records taken prior to orthodontic preparation for alveolar bone grafting of 74 children with repaired UCLP (53 male, 21 female; aged 8.9 ± 1.0 years) were studied. Directions and magnitudes of permanent maxillary central incisor and first molar rotations were recorded. Tooth absence was confirmed from longitudinal radiographic records. Incisor and molar rotations were analyzed in relation to the absence of teeth in their vicinity. Results: Distolabial rotation of the permanent maxillary central incisor was noted in 77.14% on the cleft side, while distopalatal rotation was noted in 82.19% on the noncleft side. Incisor rotation was greater when a permanent tooth was present distal to the cleft side central incisor, in the greater segment. The permanent maxillary first molar showed mesiopalatal rotation, which was greater on the cleft side and when there was absence of one or more teeth in the buccal segment. Conclusions: Presence and absence of teeth were associated with the severity of incisor and molar rotations in UCLP. Crowding of anterior teeth in the greater segment was associated with a greater magnitude of rotation of the cleft side permanent central incisor. Absence of one or more buccal segment teeth was associated with greater magnitude of rotation of the molar.

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 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.
