Introduction: This paper will study the binocular vision 3D reconstruction technology, and realize the 3D model reconstruction of the patient's head. It is applied to neurosurgery puncture surgery, and with the three-dimensional treatment model, it provides non-contact positioning and navigation for surgery. 

Materials and methods: This study retrospectively analyzed the data of 112 patients in the Department of Neurosurgery, First Affiliated Hospital of Shihezi University Medical College from October 2018 to October 2021. The safety and effectiveness of CEA and CAS were analyzed from the aspects of patients' own factors, carotid artery stenosis, success rate of operation, perioperative adverse events and long-term follow-up. By comparing the operation time, hospitalization time and hospitalization expenses of the two groups, we can provide the basis for choosing the operation mode. To analyze the relationship between different ages and perioperative complications, major adverse events and restenosis. Results: Carotid endarterectomy was performed in 34 cases and carotid stenting in 78 cases. 

Results: Recurrent laryngeal nerve and superior laryngeal nerve injuries are the most prevalent types of cranial nerve injuries that occur following CEA,according to a study by Kenneth et al.Hoarseness and coughing were reported by 2 participants after surgery in this research. Since this is the case, minimizing the risk of cranial nerve damage requires careful planning of the incision and handling of the patient during surgery.

Conclusion: (1) Carotid endarterectomy and carotid stenting are both safe and effective in the treatment of carotid stenosis, and there is no significant difference between them. (2) Patients ≥70 years old have a higher incidence of perioperative complications than patients <70 years old, and there is no significant difference in major adverse events between them. (3) The hospitalization expenses of 3)CEA group are obviously lower than those of CAS group, but the hospitalization time is slightly longer, so the operation method can be selected according to the specific conditions of patients.
