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 explain...
Prospective analysis of secondary alveolar bone grafting in cleft lip and palate patients
Journal of international oral health : JIOH, 2015
To assess the success of the uptake of bone graft in cleft alveolus of the cleft lip and palate patients, quantitatively through computed tomography (CT) scan 6 months postoperative. To assess the successful eruption of permanent lateral incisor or canine in the bone grafted area. The children age group of 9-21 years with unilateral cleft lip and palate came to the hospital, needing secondary alveolar bone grafting. A detailed history and clinical examination of the patient was taken. A 3D CT scan was taken and the volume of the cleft was measured pre-operatively. After ambulatory period, 3D CT scan of the alveolar cleft region was taken and volume of the bone grafted was measured and patient was discharged from the hospital. After 6 months, patient was recalled and again 3D CT scan was taken and the volume of remaining bone was measured. The mean volume of the defect pre-operatively is 0.80 cm(3) with a standard deviation of 0.36 cm(3) with minimum volume of the defect 0.44 cm(3) a...

To identify factors of oral health important for the final outcome, after secondary alveolar bone grafting in patients born with unilateral cleft lip and palate and compare occlusal radiographs with cone beam computed tomography (CBCT) in assessment of alveolar bone height. Observational follow-up study. Cleft Lip and Palate Team, Craniofacial Center, Uppsala University Hospital, Sweden. 40 nonsyndromic, Caucasian patients with unilateral complete cleft lip and palate. Clinical examination, CBCT, and occlusal radiographs. Alveolar bone height was evaluated according to Bergland index at a 20-year follow-up. The alveolar bone height in the cleft area was significantly reduced compared to a previously reported 10-year follow-up in the same cohort by total ( P = .045) and by subgroup with dental restoration ( P = .0078). This was positively correlated with the gingival bleeding index (GBI) ( r = 0.51, P = .0008) and presence of dental restorations in the cleft area ( r = 0.45, P = .017...
Composite correction of a unilateral cleft lip nose deformity and alveolar bone grafting
Indian Journal of Plastic Surgery, 2009
Background: Managing the cleft lip nasal deformity has always been a challenge. Even now, there is no single established universally accepted method of correction. The open alveolar gap and the ipsilateral hypoplastic maxilla are two major problems in achieving consistently good results in a cleft lip nasal deformity. In our study, after Þ rst assuring the orthodontic realignment of maxillary arches, we combined bone grafting in the alveolar gap and along the pyriform margin, with a formal open rhinoplasty approach. Methods: All the patients underwent orthodontic treatment for preparation of the alveolar bone grafting. During the process of alveolar bone graft, a strip of septal cartilage graft was harvested from the lower border of the septum which also helps to correct the septal deviation. The cancellous bone graft harvested from the iliac crest was used to Þ ll the alveolar gap and placed along the pyriform margin to gain symmetry. Through open rhinoplasty along the alar rim and additionally using Potter's incision extending to the lateral vestibule, the lateral crura of the alar cartilage on the cleft side was released from its lateral attachment and advanced medially as a chondromucosal ß ap in a V-Y fashion, in order to bring the cleft-side alar cartilage into a normal symmetric position. The harvested septal cartilage graft was used as a columellar strut. The cleft nostril sill was narrowed by a Y-V advancement at the alar base and any overhanging alar rim skin was carefully excised to achieve symmetry. Results: The results of this composite approach were encouraging in our series of 15 patients with no additional morbidity and a better symmetry of the nose and airway especially in the adolescent age group. Conclusion: This concept of simultaneous approach when appropriate for nasal correction at the time of alveolar bone grafting showed an encouraging aesthetic and functional outcome.
SUMMARY The reconstruction of the continuity of the cleft alveolar process is one of the necessary conditions in reaching complete rehabilitation of patients with total congenital cleft of upper lip, alveolar process of the maxilla and palate. The aim of this study was to evaluate late results of the secondary alveolar bone grafting (SABG). In the case of unilateral cleft, 76 SABG were performed during the period from 1994 to 2002. The operation was performed using transposional mucoperiosteal flaps by bone grafting with cortical bone plate and cancelous bone chips. The height of bone bridge was estimated at minimum 3 years after SABG. The study material comprised 50 patients with unilateral cleft alveolus. The early SABG was performed for 35 patients (70%) and late SABG - for 15 ones (30%).The primary wound healing and bone bridging was observed in all cases. More bone tissue remained in the cleft area when early SABG was performed (p = 0.000). The general height of newly formed bo...

The objective of the current study was to assess the outcome of the alveolar bone grafting (ABG) in patients with cleft palate. Thirty-one patients with complete unilateral cleft lip and palate were prospectively divided into 2 groups according to the timing of surgery: (1) secondary ABG (SABG), undertaken during mixed dentition (n = 16); and (2) tertiary ABG (TABG), undertaken during permanent dentition (n = 15). Septum height was assessed using cone beam computed tomography in 3 views (buccal, intermediate, palatal) and classified according to the modified Bergland Index, which scores the results into 5 types according to the height of the neoformed bone septum (excellent: septum with a normal height; good: septum with minor deficiency; regular: marginal defect of 925% of the root length; bad: bone deficiency on the nasal aspect; and failure). In the SABG group, 6 to 12 months postoperatively, 75% of the patients were classified as having excellent/good conditions and 25% as having regular/bad conditions. No patients were observed as having failure conditions. In the TABG group, 53% of the patients were classified as having excellent/good, 21% were classified as having regular/bad conditions, and 26% were classified as having failure conditions. Significantly better outcomes were observed for the SABG group when compared with the TABG group. In conclusion, the age at which ABG is performed is a factor that impacts on the surgical outcome. Specifically, increasing age is associated with worse outcomes.

Purpose: The literature is scarce on studies comparing secondary alveolar bone graft (SABG) performed early at approximately 5-6 years and at the conventional time at 9-11 years. This systematic literature review(SLR) aimed to compare clinical outcomes after two different timings of SABG in children with unilateral and bilateral cleft lip and palate. Methods: The inclusion criteria were autogenous iliac grafts and the following study designs: case control, cohort, clinical controlled trial (CCT), randomized CCT (RCCT), and previous SLRs. Ovid MEDLINE, Ovid EMBASE, Web of Science, Scopus, Cochrane, ProQuest and Google Scholar were the primary databases. Two calibrated examiners worked independently to select the articles. The MINORS evaluation method for surgical non-RCTs was used to assess for quality. Results: 1,111 articles were retrieved and 19 qualified. Different clinical and ra-diographic outcomes such as bone level, periodontal status, canine eruption and cleft-side tooth survival were evaluated by different assessment methods such as CBCT volume, computed tomography, periodontal evaluation, panoramic, intraoral radiographs, and Bergland scale. No RCCT or meta-analysis was found. None of the studies received the ideal score, which is 16 for non-comparison studies and 24 for comparison studies. Conclusion: Methodological variation, lack of standardization for initial cleft dimension and low-quality level rendered a fair comparison unfeasible. Although further studies are necessary, it can be assumed that early SABG also can be an acceptable option, but this was based on a single study with a reasonable level of evidence.
