Effectiveness of corticocancellous bone graft in cleft lip and palate patients: A systematic review

Abstract There are controversies related to the effects of bone grafts on tooth eruption and impaction in patients with cleft lip and palate. The aim of this systematic review was to evaluate the effectiveness of bone grafting on eruption of canines in patients with unilateral cleft lip and palate (UCLP). An electronic search was conducted in six electronic databases and gray literature, without limitations on year of publication or language. The primary outcome was the increase in rate of canine eruption; the secondary outcomes were success of the bone graft, canine impaction due to agenesis of the lateral incisor, and effect of orthodontic treatment before and after bone grafting. The risk of bias was analyzed by means of the tool Cochrane risk of bias in nonrandomized controlled trials (NRCTs) of interventions (ROBINS-I). The certainty of the evidence was assessed for outcomes reported through a narrative synthesis using grading of recommendations, assessment, development and evaluation (GRADE) approach. Four NRCTs were included, with a total of 360 patients, 283 UCLP and 77 bilateral cleft lip and palate (BCLP). The studies reported association between the increase in the rate of tooth eruption and bone graft with very low certainty of evidence, and greater experience of surgical success, with low certainty of evidence. The majority of the studies found an association between increase in the rate of canine impaction and agenesis of the lateral incisor, with very low certainty of evidence. There was very low certainty of the efficacy of secondary alveolar bone grafting for increasing the rates of eruption and reducing impaction of the maxillary canine.

Buccal Flap

Purpose The 2 most commonly used operations to treat velopharyngeal inadequacy (VPI) are superiorly based pharyngeal flap and sphincter pharyngoplasty, both of which may result in hyponasal speech and airway obstruction. The purpose of this article is to (a) describe the bilateral buccal flap revision palatoplasty (BBFRP) as an alternative technique to manage VPI while minimizing these risks and (b) conduct a systematic review of the evidence of BBFRP on speech and other clinical outcomes. A report comparing the speech of a child with hypernasality before and after BBFRP is presented. Method A review of databases was conducted for studies of buccal flaps to treat VPI. Using the principles of a systematic review, the articles were read, and data were abstracted for study characteristics that were developed a priori. With respect to the case report, speech and instrumental data from a child with repaired cleft lip and palate and hypernasal speech were collected and analyzed before and after surgery. Results Eight articles were included in the analysis. The results were positive, and the evidence is in favor of BBFRP in improving velopharyngeal function, while minimizing the risk of hyponasal speech and obstructive sleep apnea. Before surgery, the child's speech was characterized by moderate hypernasality, and after surgery, it was judged to be within normal limits. Conclusion Based on clinical experience and results from the systematic review, there is sufficient evidence that the buccal flap is effective in improving resonance and minimizing obstructive sleep apnea. We recommend BBFRP as another approach in selected patients to manage VPI. Supplemental Material https://doi.org/10.23641/asha.9919352

Dimensional Printing

Objective: To determine the current applications of 3-dimensional (3D) printing in the care of patients with cleft lip and palate. We also reviewed 3D printing limitations, financial analysis, and future implications. Design: Retrospective systematic review. Methods: Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used by 3 independent reviewers. Articles were identified from Cochrane library, Ovid Medline, and Embase. Search terms included 3D printing, 3 dimensional printing, additive manufacturing, rapid prototyping, cleft lip, and cleft palate. Exclusion criteria included articles not in English, animal studies, reviews without original data, oral presentations, abstracts, opinion pieces, and articles without relevance to 3D printing or cleft lip and palate. Main Outcome Measures: Primary outcome measure was the purpose of 3D printing in the care of patients with cleft lip and palate. Secondary outcome measures were cost analysis and clinical outcomes. Results: Eight-four articles were identified, and 39 met inclusion/exclusion criteria. Eleven studies used 3D printing models for nasoalveolar molding. Patient-specific implants were developed via 3D printing in 6 articles. Surgical planning was conducted via 3D printing in 8 studies. Eight articles utilized 3D printing for anatomic models/educational purposes. 3-Dimensional printed models were used for surgical simulation/training in 6 articles. Bioprinting was utilized in 4 studies. Secondary outcome of cost was addressed in 8 articles. Conclusion: 3-Dimensional printing for the care of patients with cleft lip and palate has several applications. Potential advantages of utilizing this technology are demonstrated; however, literature is largely descriptive in nature with few clinical outcome measures. Future direction should be aimed at standardized reporting to include clinical outcomes, cost, material, printing method, and results.
