The retrosigmoid approach for acoustic neuroma surgery offers better outcomes than translabyrinthine methods, with fewer complications and improved facial nerve preservation. This surgical technique is recommended for acoustic neuroma treatment.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Neurology

Background:

  • Acoustic neuromas, benign tumors arising from the vestibulocochlear nerve, require surgical intervention for management.
  • Surgical approaches vary, each with distinct risks and benefits impacting patient outcomes.
  • Long-term surgical experience is crucial for refining techniques and improving patient care.

Purpose of the Study:

  • To report a 24-year surgical experience with acoustic neuroma.
  • To compare the outcomes of three surgical approaches: translabyrinthine, transtemporal, and retrosigmoid.
  • To evaluate the efficacy and safety of the retrosigmoid approach in acoustic neuroma surgery.

Main Methods:

  • A retrospective review of 34 patients undergoing acoustic neuroma surgery over 24 years.

  • Analysis of three surgical approaches: translabyrinthine (11 cases), transtemporal (2 cases), and retrosigmoid (21 cases).
  • Detailed assessment of complications, including facial paralysis, cerebrospinal fluid (CSF) leaks, meningitis, and hematomas.

    • Main Results:

    • Prolonged facial paralysis rates were 27% (translabyrinthine) and 15% (retrosigmoid).
    • Complications in the translabyrinthine approach included CSF leak (5 patients) and meningitis (2 patients).
    • The retrosigmoid approach had 5 CSF leaks, 3 meningitis cases (1 fatality), and 1 posterior cranial fossa hematoma requiring reoperation. Auditory function was preserved in one patient.

    Conclusions:

    • The retrosigmoid approach demonstrates advantages in acoustic neuroma surgery, including good exposure and speed.
    • This approach offers better preservation of facial and cochlear nerves compared to other methods.
    • Facial nerve monitoring is essential, particularly with the retrosigmoid approach, to minimize morbidity.
