Abstract

Perencanaan rekonstruksi mandibula dan osteotomi fibula membutuhkan pemahaman spasial terhadap anatomi pasien, posisi pemotongan, panjang segmen tulang, dan orientasi cutting guide. Pada praktik berbasis Virtual Surgical Planning, proses perencanaan umumnya masih dilakukan melalui antarmuka desktop dan panduan fisik, sehingga interaksi terhadap model anatomi tiga dimensi belum sepenuhnya intuitif, yang dapat membatasi pemahaman spasial pengguna selama proses perencanaan bedah . Penelitian ini mengembangkan aplikasi Extended Reality berbasis visionOS untuk mendukung visualisasi dan perencanaan rekonstruksi mandibula serta osteotomi fibula secara interaktif. Aplikasi dikembangkan secara native menggunakan Swift, SwiftUI, RealityKit, ARKit, dan CreateML. Aplikasi ini menyediakan mode Virtual Reality untuk visualisasi dan manipulasi model mandibula serta fibula, serta mode Augmented Reality untuk menampilkan overlay cutting guide pada objek fisik melalui object tracking. Aplikasi juga mengintegrasikan algoritma transformasi untuk memetakan rencana pemotongan mandibula ke fibula. Evaluasi dilakukan terhadap sepuluh partisipan non-klinis menggunakan System Usability Scale (SUS) dan Immersive Experience Questionnaire (IEQ), serta evaluasi kualitatif oleh seorang dokter bedah. Hasil evaluasi menunjukkan bahwa aplikasi memperoleh median skor SUS 68,75 dari 100 dan median skor IEQ 162,5 dari 217, sehingga memiliki usability yang marginal (dapat ditingkatkan) dan mampu memberikan pengalaman visualisasi yang imersif. Masukan dokter menunjukkan bahwa visualisasi 3D dan integrasi alur VR-AR berpotensi mendukung pemahaman spasial dalam perencanaan rekonstruksi mandibula. Penelitian ini menunjukkan bahwa aplikasi XR berbasis visionOS dapat menjadi dasar pengembangan sistem perencanaan bedah yang lebih interaktif, intuitif, dan fleksibel.

Mandibular reconstruction and fibular osteotomy planning require spatial understanding of patient anatomy, cutting positions, bone segment lengths, and cutting guide orientations. In current Virtual Surgical Planning workflows, planning is generally performed using desktop-based interfaces and physical guides, making interaction with three-dimensional anatomical models less intuitive and potentially limiting users' spatial understanding during surgical planning. This study developed a visionOS-based Extended Reality application to support interactive visualization and planning of mandibular reconstruction and fibular osteotomy. The application was developed natively using Swift, SwiftUI, RealityKit, ARKit, and CreateML. It provides a Virtual Reality mode for visualization and manipulation of mandibular and fibular models, as well as an Augmented Reality mode that displays cutting guide overlays on physical objects through object tracking. The application also integrates a transformation algorithm to map mandibular cutting plans onto the fibula. Evaluation was conducted with ten non-clinical participants using the System Usability Scale (SUS) and the Immersive Experience Questionnaire (IEQ), complemented by a qualitative assessment from a surgeon. The results showed that the application achieved a median SUS score of 68.75 out of 100 and a median IEQ score of 162.5 out of 217, indicating a marginal level of usability (can be improved) and the ability to provide an immersive visualization experience. Feedback from the surgeon suggested that the 3D visualization and integrated VR-AR workflow have the potential to support spatial understanding in mandibular reconstruction planning. This study demonstrates that a visionOS-based XR application can serve as a foundation for developing more interactive, intuitive, and flexible surgical planning systems.
