A simple suturing technique secures titanium cerebellar retractors during craniotomy, preventing shifts during electromagnetic neuronavigation and intraoperative MRI. This method ensures stable instrument and tissue positioning for improved surgical outcomes.
Area of Science:
- Neurosurgery
- Surgical Instrumentation
- Medical Devices
Background:
- Stainless steel retractors can impede electromagnetic neuronavigation and intraoperative magnetic resonance imaging (ioMRI).
- Titanium retractors are an alternative but prone to displacement during surgery.
- Minimizing retractor movement is crucial for surgical accuracy and patient safety.
Purpose of the Study:
- To present a straightforward technique for stabilizing titanium cerebellar retractors during craniotomy.
- To address the issue of retractor displacement in neurosurgical procedures involving advanced imaging.
Main Methods:
- Utilized titanium retractors in neurosurgical operations requiring electromagnetic neuronavigation or ioMRI.
- Secured titanium retractors by placing 2-0 silk sutures around retractor tongs and tying them externally.
- Applied sutures on both sides of the retractor for enhanced stability.
Main Results:
- The implemented suturing technique successfully maintained titanium retractors in their intended positions throughout the craniotomy.
- No significant retractor movement was observed after the application of the described securing method.
Conclusions:
- A simple, safe, and practicable suturing technique effectively secures titanium cerebellar retractors during craniotomy.
- This method minimizes retractor movement, reducing surgeon frustration and improving procedural reliability.
- The technique is beneficial for neurosurgical procedures utilizing electromagnetic neuronavigation or ioMRI.
