Authors' objectives: To assess the effectiveness, cost-implication, safety and organisational issues related to the application of digital assisted technology for oral and cranio-maxillofacial surgery.

Authors' results and conclusions: Digital/ computer assisted oral & cranio-maxillofacial surgery has better soft tissue prediction and CMF skeletal harmony for both maxillary and mandibular site. As for the navigation, the accuracy and zygomatic-maxillary (ZMC) eminence were better compared to surgery without navigation. However, the asymmetry index and orbital volume ZMC width was comparable between both groups. For safety, there was similar adverse event rate in both groups. In terms of organisational issues, digital/ computer assisted oral & cranio-maxillofacial surgery has shorter operative/surgery time, reconstructive, ischaemic time and length of stay. Digital/ computer assisted oral & cranio-maxillofacial surgery was also found to have lower cost compared to conventional method with a cost saving of approximately RM1,632 per surgery. However, a minimum number of 15 surgeries per month in a hospital is suggested to achieve a minimum savings.

Authors' recommendations: Based on the above review, digital assisted oral & craniomaxillofacial surgery may be adopted/ implemented in Ministry of Health, Malaysia. However, volume of patient or surgery and adequate operation theatre (OT) time should be taken into consideration to achieve potential cost saving.

Authors' methods: Electronic databases were searched through the Ovid interface: Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R) 1946 to April 2021. Searches were also run in INAHTA database, PubMed database and U.S. Food and Drug Administration (USFDA) website. Google and Google Scholar were also used to search for additional web-based materials and information. Additional articles were identified from reviewing the references of retrieved articles. Last search was conducted on 12th June 2021. A cost comparison analysis was conducted using the Microsoft Excel 2013. The total costs of each surgeries were calculated using the time-driven procedure-based costing.
