Recently, the Department of Otorhinolaryngology Head and Neck Surgery of Yantai Yuding Hospital took the lead in combining virtual reality, mixed reality and 3D printing and many other high-tech technologies to successfully implement a case of subcranial tumor resection. The operation was smooth and the tumor tissue was completely removed. Postoperative cognitive, sensory, and motor function were normal, and the patient was successfully discharged on the 7th day after surgery. Virtual reality + mixed reality + 3D printing technology successfully applied in ENT, neck and neck surgery, is the first case in our province.
It is understood that "virtual reality" + "mixed reality" is to read the patient's CT, MR and other image data through technical means to generate a 3D holographic image model. With MR glasses, the doctor can clearly see the 3D image of the patient's lesion, and can Zoom, rotate, move, change transparency, etc., and combine 3D images with the patient to understand the anatomical relationship between the lesion and the surrounding, and improve the safety of the operation.
Apply virtual reality technology for effective preoperative communication
The patient who underwent the operation was a 48-year-old man who was admitted to the hospital for an oblique angle. CT and MRI results showed lesions in the left tympanic and lateral skull base tumors. Because the patient's tumor location is relatively deep, involving the left facial nerve, cochlea, vestibule, semicircular canal, and the surrounding bone around the face, the upper part of the invasion of the temporal lobe brain tissue, the conventional treatment is very difficult.
"In the past, this kind of illness was mainly based on craniotomy. This type of surgery has great damage, and the risks of nerve function, brain tissue damage, infection, etc. are also high. Therefore, patients recover slowly and stay in hospital for a long time." Yantai Yuding Hospital ENT Head and Neck Sun Yan, deputy director of surgery, said: "In the early stage, under the support and leadership of the director of the department, Song Xicheng, the department has carried out 7 preoperative 3D imaging techniques in the nasal skull base and head and neck tumors, and already has a more mature application 3D. Imaging guides the experience of preoperative surgical planning, but combining 3D with virtual mixed reality technology for the first time in intraoperative applications."
In order to optimize the surgical plan, Zhang Yu, deputy director of the Department of Otorhinolaryngology Head and Neck Surgery, used the imaging data to fully communicate with the 3D engineers to create a holographic three-dimensional model of the tumor and surrounding important structures. The department also organized a multidisciplinary consultation (MDT). ), the best treatment plan was formulated; Sun Yan, deputy chief physician, conducted a simulated exercise before surgery. When communicating with the patient, MR glasses were worn simultaneously with the patient to visually display the size and location of the tumor and the vital organs such as the tumor and peripheral vascular nerves. The anatomical relationship has been fully recognized by the patient.
With the advancement of technology, especially the application of virtual reality + mixed reality + 3D printing technology, doctors have a high-dimensional "perspective" surgical area and "God perspective" to ensure more accurate, safe and improved surgical efficiency. Accelerate the recovery of patients after surgery. The successful application of this technology marks a solid step in the field of precision tumor treatment in Yantai Yuding Hospital's otolaryngology head and neck surgery!
