Surgery for peripheral entrapment neuropathy aims to decompress the affected nerve and optimize the visualization of anatomical details during surgery. This paper describes our experience using the ORBEYE exoscope (Olympus) during surgery for tarsal tunnel syndrome (TTS). The patient was a 70-year-old male with complaints of bilateral pain and numbness on the plantar surface of the bilateral soles and medial halves of both lower limbs. He was diagnosed with idiopathic TTS with the American Orthopedic Foot and Ankle Score (AOFAS) of 20/100. Surgery for the right foot was performed under local anesthesia with the patient's body in the lateral position. All procedures were performed using the ORBEYE exoscope view. The posterior tibial artery (PTA) was transposed, and the flexor retinaculum was reconstructed between the PTA and posterior tibial nerve. Indocyanine green (ICG) video angiography confirmed the absence of PTA flow disturbance. One month after the first operation, left foot surgery was performed. Three months later, the AOFAS had improved from 20/100 to 50/100. The ORBEYE exoscope is useful in TTS treatment and represents a feasible and comfortable technique for entrapment neuropathy surgery. In addition, ICG capability is an effective tool for confirming blood flow in PTA after transposition.

Parotid surgery is generally performed with the naked eye or using surgical loupes. However, this approach has technical disadvantages. Therefore, this study aimed to compare the use of an exoscope with that of loupe for parotidectomies.

Augmented reality technologies provide transformative solutions in various surgical fields. Our research focuses on the use of an advanced augmented reality system that projects 3D holographic images directly into surgical footage, potentially improving the surgeon's orientation to the surgical field and lowering the cognitive load. We created a novel system that combines exoscopic surgical footage from the "ORBEYE" and displays both the surgical field and 3D holograms on a single screen.

Typically, CAS is performed via a transfemoral, transbrachial, or transradial approach. However, direct puncture CAS (DP-CAS) is preferred in cases where conventional access routes are challenging, such as in the presence of cervical vascular tortuosity or thoracic aortic aneurysm.

Article Synopsis
- The exoscope, a more ergonomic alternative to traditional microscopes, is being explored in general surgery, specifically for transanal procedures like ileal-pouch anal anastomosis.
- Surgeons performed a transanal procedure using the ORBEYE™ exoscope system, which provided a high-resolution, 3D view on a large screen, enhancing their ability to operate while keeping a comfortable position.
- The results indicate that the exoscope offered excellent visualization and could improve surgical training by allowing trainees to see techniques clearly, suggesting its potential as a valuable tool in colorectal surgery.

The evolution in microsurgery using high-definition three-dimensional (3D) cameras has provided the opportunity to replace conventional operating microscopes (OM), improving ergonomics for microsurgeons. Several 3D exoscope systems have already demonstrated good surgical field visualization in a 3D space in performing microvascular anastomosis with favorable maneuverability and non-inferiority compared to OM. We present the application of the 4K-3D ORBEYE system (Olympus Inc.
