Abstract：Objective To make a visualized analysis of the research hotspots and trends in master's and doctoral disser-tations related to orthognathic surgery through bibliometric methods.Methods A computer-based search was conduct-ed for orthognathic surgery-related master's and doctoral dissertations in the China National Knowledge Infrastructure(CNKI),Wanfang,and VIP databases spanning from 1987 to 2023.NoteExpress was utilized for literature management and screening,while Microsoft Excel and Origin were employed to analyze the annual publication volume of the included dissertations.CiteSpace6.2.R7 was used to perform co-occurrence,clustering,and burst analysis of keywords,and a knowledge map was created accordingly.Results The annual publication volume of orthognathic surgery-related disser-tations exhibited an upward trend,peaking in 2019 with 9.13％(77/843)of the total publications.The top five most fre-quent keywords were orthognathic surgery(76 times),or-thognathic operation(69 times),cephalometry(38 times),upper airway(32 times),and 3D reconstruction(24 times).The above were also the top 5 keywords by co-oc-currence.The keywords were clustered into 15 labels:#0 stability,#1 three-dimensional measurement,#2 mandi-ble,#3 cephalometry,#4 preoperative orthodontics,#5 image processing,#6 biomechanics,#7 orthodontics,#8 osseous,#9 object-oriented,#10 average angle,#11 clinical effectiveness,#12 orthodontic treatment,#13 sagittal split osteotomy of the mandibular ramus,and #14 rib-cartilage grafting.The top five keywords with the highest burst strength were 3D CT,cephalometry,cone beam CT,orthognathic surgery,and preoperative orthodontics.Conclusion The research in or-thognathic surgery-related fields has been paid increasing attention to in master's and doctoral dissertations,and the re-search content is broad.Focus is on the application of digital technology and multidisciplinary treatment,which is also the key directions for future researches.
