Utilization of Bonney's Blue Dye as an Adjunct to Orthognathic Surgery Augmented by Virtual Surgical Planning.

Virtual surgical planning (VSP) has revolutionized orthognathic and craniomaxillofacial surgeries by enabling precise 3-dimensional analysis, detailed osteotomy planning, and custom fabrication of surgical guides and fixation hardware. However, the visualization of registration holes-critical for accurate plate fixation-remains challenging, especially in a blood-filled surgical field. This paper presents a novel technique to enhance the visibility of registration holes using Bonney's blue dye. The technique involves injecting micro-aliquots of Bonney's blue dye (a mixture of crystal violet and brilliant green) into the registration holes before performing osteotomies. This approach ensures that the holes remain clearly marked despite potential visual contamination in the surgical field. The dye helps to identify screw placements and align patient-specific fixation plates more accurately. The proposed method addresses common difficulties in aligning registration holes with patient-specific plates during surgery. Bonney's blue dye provides a clear contrast against the bone, making the registration holes more visible and easier to locate. This improvement is particularly advantageous in a bloody surgical field and benefits less experienced surgeons by offering a straightforward solution to enhance accuracy and efficiency. The technique can also reduce overall operative time by minimizing the time spent locating and aligning the registration holes. Utilizing Bonney's blue dye in virtual surgical planning significantly improves the visibility and alignment of registration holes in orthognathic surgeries. This simple, cost-effective method enhances surgical precision and efficiency and can be applied to other computer-assisted surgical procedures in craniofacial surgery.
