“…Of the 26 PRS-authored publications, 9–34 6 (23.1%) publications were authored by PIs located in the United States, whereas the remainder of the PIs were based outside the United States (Supplementary Digital Content, Table 3, http://links.lww.com/SCS/D937). Although VSP was used for preoperative surgical planning in all papers, 12 studies (46.2%) further used VSP to fabricate intraoperative guides or splints and 6 studies (23.1%) superimposed pre- and post-surgery VSP models to determine VSP accuracy.…”

Background: Virtual surgical planning (VSP) has gained popularity for preoperative orthognathic surgery planning and is increasingly being employed by surgeons trained in plastic and reconstructive surgery (PRS) or oral and maxillofacial surgery (OMS). This review assesses the introduction of VSP as a new technology and its impact on orthognathic surgery research and practices based upon surgeon training. Methods: Two PubMed literature reviews were conducted. The first classified publications on VSP for orthognathic surgery by training (OMS-or PRS-trained surgeons) and compared focuses, timing, and journals of publications from each group of surgeons. The second evaluated how orthognathic surgery publication volumes changed with VSP introduction. English articles published from inception until January 2020 (first review) and November 2020 (second review) were included. Results: The first literature review retrieved 419 unique publications, with 188 studies selected for inclusion: 162 were published by OMS-trained principal investigators (OMS-authored) and 26 by PRS-trained principal investigators (PRSauthored). Plastic and reconstructive surgery-authored publications regarding VSP use in orthognathic surgery increased after the first publication in 2000, but at a significantly slower rate (0.2 new publications/year) than OMS-authored publications (P < 0.01). Aesthetics was discussed in significantly more PRS-authored publications (76.9% compared to 28.4% of OMS-authored publications). The second review revealed that over 80.6% of orthognathic surgery literature was published after 2008, the year VSP was first integrated into orthognathic surgery workflow. Conclusions: Following the introduction of VSP, orthognathic surgery research output has differed between PRS and OMS based on publication speed, volume, and research focuses.Further research is necessary to evaluate how VSP has impacted PRS and OMS clinical practice.

“…Meanwhile, the application of digital technology enables the design of individualized orbital zygomatic prostheses that are more in line with the developmental characteristics of different patients and achieve better shape effects. 8 In addition to the dysplasia or defect of the orbitozygomatic bone, the soft tissue in the midface area also has hypoplasia to varying degrees in these patients, so simple reconstruction of the orbitozygomatic region sometimes does not bring significant results. Although some patients have orbitozygomatic dysplasia, the anterior one third of the zygomatic arch remains, the collapse of the orbitozygomatic region is not serious, so that the patient's midface can be significantly improved by temporal expansion flap 9 and autologous fat transplantation with reduced trauma.…”

Objective: To discuss and summarize the comprehensive serial surgical treatment of Treacher Collins syndrome. Materials and Methods: From September 2012 to January 2020, 12 patients with Treacher Collins syndrome were treated by autologous fat graft, mandibular distraction osteogenesis, orbitozygomatic reconstruction with calvarial external lamina, orthognathic surgery combined with postoperative orthodontics, transplantation of upper eyelid orbicularis myocutaneous flap, lateral canthal ligament reduction, and other methods. The authors evaluated the postoperative improvement, summarized experiences, and reviewed literatures about the comprehensive serial treatment of Treacher Collins syndrome. Results: All patients showed significant improvement in appearance and function, and no complications were found during the follow-up period of 5 months to 3 years. Conclusions: The deformities of Treacher Collins syndrome involves multiple craniofacial region, and only by formulating comprehensive serial treatment strategies according to the malformation characteristics of different patients can the best effect be achieved.

“…As digital techniques for cranial modeling continue to advance and become more readily available, increased utilization of VSP for cases of skeletal facial reconstruction and complex craniosynostosis repair is anticipated. 6,15,16 It is in this setting that we will discuss our experience with the use of VSP for cases of complex craniosynostosis while also presenting our comparative analysis to our cohort of complex cases completed without the use of VSP.…”

Background: Virtual surgical planning (VSP) decreases reliance on intraoperative subjective assessment of aesthetic and functional outcomes in craniofacial surgery. Here, we describe our experience of using VSP for complex craniosynostosis surgery to inform preoperative decision making and optimize postoperative outcomes. Methods: Chart review was performed for children treated with craniosynostosis at our institution from 2015 to 2021. Eight VSP maneuvers were defined and assigned to each patient when applicable: (1) complex cranioplasty: combined autologous and synthetic; (2) autologous cranioplasty; (3) synthetic cranioplasty; (4) vector analysis and distractor placement; (5) complex osteotomies; (6) multilayered intraoperative plans; (7) volume analysis; and (8) communication with parents. Outcomes between VSP and non-VSP cohorts were compared. Results: Of 166 total cases, 32 were considered complex, defined by multisutural craniosynostosis, syndromic craniosynostosis, or revision status. Of these complex cases, 20 underwent VSP and 12 did not. There was no difference in mean operative time between the VSP and non-VSP groups (541 versus 532 min, P = 0.82) or in unexpected return to operating room (10.5% versus 8.3%, P = 0.84). VSP was most often used to communicate the surgical plan with parents (90%) and plan complex osteotomies (85%). Conclusions: In this cohort, VSP was most often used to communicate the surgical plan with families and plan complex osteotomies. Our results indicate that VSP may improve intraoperative efficiency and safety for complex craniosynostosis surgery. This tool can be considered a useful adjunct to plan and guide intraoperative decisions in complex cases, reducing variability and guiding parental expectations.
