Multi-size, Multi-angle Microbipolar Forceps for Skull Base Surgery: Technical Note.

ABSTRACT

Objective Hemorrhage control in skull base surgery is critical but hindered by the lack of instruments suitable for coagulating structural curves and corners. The main impediment is that most of the instruments currently used are right-angled and unsuitable because anatomical and pathologic structures are three-dimensional objects having complex curves and corners. In this article, we present a solution the use of angled bipolar microforceps having a range of small diameters and angles for dissection and coagulation. Methods Utilizing modern design software and up-to-date synthetic and metallic materials, a variety of nonstick bipolar microforceps with different angles and very fine tips (0.2-1.2 mm) were designed and constructed for use on different anatomical and pathologic curves. The tips of the forceps were made very fine to improve coagulation precision as well as to improve microdissection dexterity. The blades were made long and thin to improve visibility during coagulation and dissection procedures. As a result, these multi-size, multiangle micro instruments can be used not only for coagulation but also for microdissection or tumor removal in most anatomical areas accessed during the course of skull base surgery Results The research, design, and construction of a new bipolar microforceps with different angles and sizes represents a technical innovation that can lead to improved surgical outcomes. Conclusion The new micro-instruments enhance the quality and quantity of tumor and tissue resection and dissection in skull base surgery and open the possibility of new surgical approaches to microscopic tumor resection and hemorrhage coagulation in the anatomical areas of the skull base.
