Background.
Microvascular decompression (MVD) is a widely accepted treatment for neurovascular disorders associated with
facial pain and
spasm. The
endoscope has rapidly become a standard tool in
neurosurgical procedures; however, its adoption in lateral approaches to the posterior fossa has been slower. The
endoscope is used primarily to assist conventional microscopic techniques. We are interested in developing fully endoscopic approaches to the cerebellopontine angle, and here, we describe our preliminary experience with this procedure for MVD. Methods. A retrospective review of our two-year experience from 2011 to 2012, transitioning from using conventional microscopic techniques to
endoscope-assisted microsurgery to fully endoscopic MVD, is provided. We also reviewed our preliminary outcomes during this transition. Results. There was no difference in the surgical duration of these three procedures. In addition, the majority of procedures performed in 2012 were fully endoscopic, suggesting the ease of incorporating this solo tool into practice.
Pain outcomes of fully endoscopic MVD appear to be very similar to those of both conventional and
endoscope-assisted MVDs. Complications occurred in all groups at equally low rates. Conclusion. Fully endoscopic MVD is both safe and effective. By enhancing visualization of structures within the cerebellopontine angle, endoscopy may prove to be a valuable adjunct or alternative to conventional microscopic approaches.
