“…Of course, we know that using this novel approach in the 21 st century medicine would enable all systems of simulated reality to share the ability and offer the user/tele-user [10,11] (Figure 7) to move and act within the apparent worlds instead of the real world, as described in our previous publications6 and demonstrated in the OR during operative procedure on a patient with maxillary sinus cyst protruding to the oral cavity through the oroantral fistula. In line with our previous experimental studies published in the past two decades [1,10,12] and experiences reported by other authors [13][14][15], our primary objective was to establish whether this new approach in visualization of human anatomy would avoid the risks associated with real endoscopy and minimize procedural difficulties when used prior to performing an actual endoscopic examination [16]. Therefore, bearing in mind the definition of VR ("impression of being present in a virtual environment, such as virtual/tele-VE of the patient's head that does not exist in reality is called VR", we tested the possibility to derive spatial cross-sections at selected anatomic cutting planes in rhino-surgery, which would provide an additional insight into the internal regions observed [6].…”

“…According to our long-standing use of this and similar approaches in clinical practice (diagnostics and surgery/TS) [12,17,18] and experiences reported by other authors [19][20][21][22], we have realized that it is quite simple to enable the animated image of the course of surgery/telesurgery be created in the form of navigation, i.e. the real patient operative field fly-through, as it has been done from the very beginning (since 1998) in our computer assisted-TSs [6] (Figure 9).…”

Objectives: This study presents the use of our original contactless interface as a plug-in application for OsiriX-DICOM-viewer platform using a hardware sensor devicecontroller that supports hand/finger motions as input, with no hand contact, touching, or voice navigation. It would be possible to modify standard surgical parameters in the fly gesture-controlled incisionless surgical interventions. Methods:The accuracy of computer-generated models was analyzed according to T. Galeta/2017. Our original special plug-in-application provided different types of gestures for three-dimensional-virtual reality navigation. Our hardware sensor device controlling the system without touching any other device served as an interface for camera positioning in three-dimensional virtual endoscopy-views. The impression of panoramic three-dimensional volume rendering-viewing was given by pivoting the camera around a focus fixed on the object.Results: This novel technique enables surgeons to get complete and aware orientation in the operative field, where 'overlapping' of the real and virtual anatomic models is inevitable. Our human mind and understanding of this new surgery work by creating completely new models of human behavior and understanding spatial relationships, along with devising assessment that will provide an insight into our human nature. Any model and/or virtual model of the surgical field is defined as it actually exists in its natural surroundings. Conclusion:We offer an alternative to closed software systems for visual tracking, with an initiative for developing the software framework that will interface with depth cameras, with a set of standardized methods for medical applications such as hand gestures and tracking, face recognition, navigation, etc. This software should be an

Seeing Through The Problem: The Use Of 3-D CT Reconstruction In The Removal Of Multiple Foreign Bodies

We report an unusual but invaluable use of three dimensional computed tomography (CT) reconstruction for the removal of multiple foreign bodies in a 7 year old boy following trauma. In a road traffic accident (RTA) a 7 year old boy sustained multiple facial lacerations from shattered glass.Facial CT scans were performed to exclude a mandible fracture requiring intervention, following which it was possible provide three dimensional reconstructions of the boy's face revealing thirteen pieces of glass. Using this reconstruction as a guide in theatre twelve of the thirteen pieces of glass were retrieved with a satisfactory cosmetic result. Case reportWe report a 7-year-old boy who presented following an RTA in which he was a restrained rear seat passenger. He was noted to be agitated at the scene and required to be sedated prior to transfer to the accident and emergency department. On arrival his airway, breathing and circulation were stable.His GCS was 10 with eyes opening to pain, vocalising inappropriately and localising to pain. He was noted to have multiple lacerations on the left side of his face, with fragments of glass visible in the lacerations, along with significant swelling of the left cheek and mandibular area. He was intubated and ventilated for a CT head scan. This scan excluded an intracranial bleed and he was transferred to the Children's Hospital ventilated with spinal immobilisation in situ.As he was ventilated it was not possible to clear his cervical spine and likewise it was not possible to achieve the standard plain radiographs to visualise his mandible. He underwent a facial CT scan which revealed bilateral mandibular condyle fractures, which did not require intervention. (Figure 1)

Objectives: There are many new, innovative approaches and techniques, as technological advances in the modern surgery, such as CAS, NESS and robotic surgery, but nowadays we also can use the "surgery in-the-air". We can understand this newest approach as a "contactless surgery", and as a part of adopting augmented and virtual reality for next generation of information technology and medical healthcare.Methods: Our experience in using DICOM viewer and computer HD sensor device that supports hand and finger motions, to control the surgical system without touching anything, has definitely upgraded our understanding of the "human anatomical natural world" and enabled us to develop appropriate sensitivity and awareness of different coloration of normal and pathologic tissues in the pre/intraoperative diagnostics/surgical activities.Results: In our experience, taking an innovative "virtual surgical ride" per viam topclass contactless-surgery system, through the human anatomy, is a completely nontraumatic, safe, and perfect starting point for exploring this surgical philosophy with many distinct and very pleasant anatomic neighborhoods of the human head, as we have already discussed.
