Endoscopy provides enhanced visualization during vestibular nerve surgery for Meniere's disease, leading to complete neurectomy and symptom relief. This technique offers advantages over traditional microsurgery.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Medical Technology

Background:

  • Meniere's disease is a disorder of the inner ear causing vertigo and hearing loss.
  • Vestibular neurectomy is a surgical treatment for intractable Meniere's disease.
  • Endoscopes offer potential advantages in visualization and surgical access compared to microscopes.

Purpose of the Study:

  • To evaluate the safety and effectiveness of endoscopy during vestibular nerve neurectomy.
  • To compare endoscopic techniques with standard microsurgery for this procedure.

Main Methods:

  • Retrosigmoid craniotomy for vestibular nerve neurectomy in 10 patients with Meniere's disease.
  • Utilized Hopkins telescope endoscopy for visualization and surgical assistance.
  • Pre- and postoperative audiometric and electronystagmography evaluations were performed.

Main Results:

  • Complete vestibular nerve neurectomy was achieved in all 10 patients.
  • Endoscopy improved visualization of cranial nerves and neurovascular structures, minimizing cerebellar retraction.
  • All patients experienced elimination of vertigo episodes; one patient's Tumarkin otolithic crisis resolved.

Conclusions:

  • Posterior fossa endoscopy is a safe and effective adjunct to vestibular nerve neurectomy.
  • Endoscope-assisted surgery offers improved visualization, potentially more complete neurectomy, and reduced risks like CSF leakage.
