Orbital fracture and orbital floor reconstruction surgery is characterised by limited surgical exposure and high risks. Before the advent of digital technology, the design and implementation of the surgical scheme for orbital floor reconstruction surgery mainly depended on the intuitive understanding of imaging and the clinical experience of surgeons, with strong unpredictability and experience dependence. Surgical navigation systems with real-time positioning and imaging functions, when used in orbital reconstruction surgery, can detect the real-time intraoperative position, avoid risks, and assist in locating the reconstruction position to ensure the accuracy of orbital reconstruction, with the help of a preoperative surgical plan. Many studies have confirmed its effect. Unilateral orbital fracture and orbital floor reconstruction surgery is one of the earliest and most widely used surgical techniques in maxillofacial surgery. Experts from the Society of Oral and Maxillofacial Surgery, Chinese Stomatological Association have fully discussed and formulated this expert consensus on navigation-guided unilateral orbital fracture and orbital floor reconstruction techniques to standardise the clinical surgical procedures and promote its application.

Deformities of the maxillofacial region following trauma and ablative surgery are devastating and not uncommon. Reconstruction of such defects is a surgically challenging procedure. Conventionally, reconstruction of dental arch defects lacks preoperative customised planning and relies heavily on the surgeon experience to ensure optimum surgical outcomes. The restoration of the dental arch shape and function has taken precedence after an extensive tumour resection surgery, especially in the current age of technological advancement. Thus, personalised and accurate reconstruction of dental arch defects has become a new goal. Computer-assisted surgery, especially navigation-assisted surgery, has gained popularity of late, in reconstructing deformities and restoring facial symmetry, appearance and function in the maxillofacial region. This technology provides a clearer three-dimensional visualisation of the area of interest and its relationship with the adjacent vital structures. Together with preoperative virtual surgical planning, it allows more specific and accurate osteotomies, thus reducing the ischemia and total operating times substantially. The risk of complications is also minimised whilst improving the final surgical outcomes. The use of the intraoperative navigation system and other computer-assisted surgical techniques during surgery can significantly improve the precision of the reconstruction of dental arch deformities, and achieve personalised and functional reconstructive goals while enhancing the quality of life of patients postoperatively. The Society of Oral and Maxillofacial Surgery, Chinese Stomatological Association provides the present professional perspective and treatment protocol for navigation-guided reconstruction of dental arch defects, to allow standardisation of the technique while promoting its application among oral and maxillofacial surgeons.

眼眶骨折重建手术术区视野暴露有限，手术风险较高。在数字化技术出现之前，眶壁重建的手术方案设计与实施主要依赖影像学直观理解和术者的临床经验，有很强的不可预见性和经验依赖性。大量文献报告证实，外科手术导航具备实时定位及显像功能，应用于眼眶重建手术中，既可以实时探测手术位置，规避风险，又可以在术前手术计划的帮助下，辅助定位重建位置，确保眼眶重建的精确度。单侧眼眶骨折眼眶重建手术也是颌面部手术中导航技术应用最早、最广泛的术式之一。中华口腔医学会口腔颌面外科专业委员会组织专家经过充分讨论，制定导航引导单侧眼眶骨折重建术技术流程及操作的专家共识，以规范该技术的临床操作流程，促进其推广应用。.

Deformities of the maxillofacial region following trauma and ablative surgery are devastating and not uncommon. Reconstruction of such defects is a surgically challenging procedure. Conventionally, reconstruction of the jaw defects lacks pre-operative customized planning and relies heavily on surgeons\' experiences to ensure optimum surgical outcomes. The restoration of jaw shape and function has taken precedence after an extensive tumor resection surgery, especially in the current age of technological advancement. Thus, personalized and accurate reconstruction of jaw defects has become a new goal. Computer-assisted surgery especially navigation-assisted surgery has gained popularity of late, in reconstructing deformities and restoring facial symmetry, appearance and function in the maxillofacial region. This technology provides a clearer three-dimensional visualization of the area of interest and its relationship with the adjacent vital structures. With pre-operative virtual surgical planning, it allows more specific and accurate osteotomies, thus reducing the ischemia and total operating times substantially. The risk of complications is also minimized whilst improving the final surgical outcomes. The use of intra-operative navigation system and other computer-assisted surgical techniques in the surgery can significantly improve the precision of the reconstruction of jaw deformities and achieve personalized and functional reconstructive goals while enhancing the patients\' quality of life post-operatively.
