Differences in Practice in Alveolar Bone Grafting Among American Cleft Palate-Craniofacial Association Members.

Abstract

The purpose of this study is to determine areas of agreement and disagreement among American Cleft Palate-Craniofacial Association (ACPA)members in the clinical practice of alveolar bone grafting (ABG), to guide further research to optimize ABG practices. A cross-sectional survey was conducted. The respondents were in an academic, combination, or private practice. The respondents were either plastic or oral and maxillofacial surgeons (OMFS) from various countries. A de-identified 24-question online survey was distributed to ACPA surgeon members utilizing the Research Electronic Data Capture (REDCap) tool. Data collected included surgeon specialty, use of various alveolar bone graft surgical techniques, as well as protocols. There was more variability than consensus between specialties with regards to the preoperative workup, timing of surgery, materials used for bone graft, surgical techniques, perioperative management, and postoperative evaluation. There was consensus on grafting during mixed dentition, not staging soft and hard tissue closure, and using iliac crest for primary and secondary grafting. Disagreements involved factors used to time the procedure and type of imaging used to assess viability. Technical differences involved incision type, part of bone grafted, use of minimally invasive technique, and material used for revisions. Aside from areas of consensus among surgeons on ABG, several areas, including use of bone substitutes in revision grafting, incision and type of iliac crest graft used during initial grafting, and postoperative protocols, had no consensus. These areas should be targets of further research to determine if there truly is an optimal method to perform ABG. The study was approved by the University of Illinois at Chicago Institutional Review Board. A de-identified 24-question online survey was distributed to surgeon members of the ACPA utilizing the REDCap tool on August 7, 2020. The survey questions consisted of multiple choice and multiple selection questions including an option to select “other” and specify the information in a blank space. Data collected included surgeon specialty, use of various alveolar bone graft surgical techniques, as well as pre and postoperative protocols. The full survey is included in online Supplemental material. Data analysis was performed in SPSS Statistics 27 (IBM Corp.). Descriptive statistics were performed, and chi-square was used to test for significant differences in survey responses between groups.
