Minimally Invasive Multiport Surgery of the Lateral Skull Base

چکیده
OBJECTIVE Minimally invasive procedures minimize iatrogenic tissue damage and lead to a lower complication rate and high patient satisfaction. To date only experimental minimally invasive single-port approaches to the lateral skull base have been attempted. The aim of this study was to verify the feasibility of a minimally invasive multiport approach for advanced manipulation capability and visual control and develop a software tool for preoperative planning. METHODS Anatomical 3D models were extracted from twenty regular temporal bone CT scans. Collision-free trajectories, targeting the internal auditory canal, round window, and petrous apex, were simulated with a specially designed planning software tool. A set of three collision-free trajectories was selected by skull base surgeons concerning the maximization of the distance to critical structures and the angles between the trajectories. RESULTS A set of three collision-free trajectories could be successfully simulated to the three targets in each temporal bone model without violating critical anatomical structures. CONCLUSION A minimally invasive multiport approach to the lateral skull base is feasible. The developed software is the first step for preoperative planning. Further studies will focus on cadaveric and clinical translation.

Quality Assurance of Multiport Image-Guided Minimally Invasive Surgery at the Lateral Skull Base
For multiport image-guided minimally invasive surgery at the lateral skull base a quality management is necessary to avoid the damage of closely spaced critical neurovascular structures. So far there is no standardized method applicable independently from the surgery. Therefore, we adapt a quality management method, the quality gates (QG), which is well established in, for example, the automoti...

متن کاملMinimally invasive total splenectomy in dogs: A clinical report
Cases of minimally-invasive surgery are gaining acceptance among surgeons and animal owners. One type of minimally-invasive surgery is total splenectomy, which is indicated for splenic tumors, trauma, torsions, and for dogs that require blood transfusion. To assess the safety of the technique, experimental laparoscopic splenectomies were performed in dogs for the first time in Iran. Three adult...
متن کاملMinimally invasive endoscopic pericranial flap: a new method for endonasal skull base reconstruction.
OBJECTIVES One of the major challenges of cranial base surgery is reconstruction of the dural defect. Following a craniofacial resection, the standard reconstructive technique is direct suture repair of the dural defect with a fascial graft and rotation of an anteriorly based pericranial scalp flap to cover the dura. The introduction of endoscopic techniques and an endonasal approach to the ven...
