The transcochlear approach effectively treats petroclival tumors, achieving high resection rates. This technique is ideal for intradural tumors extending to the brainstem in patients with no serviceable hearing.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Skull Base Surgery

Background:

  • Petroclival tumors present complex surgical challenges due to their location.
  • The transcochlear approach offers a corridor for accessing these challenging tumors.

Purpose of the Study:

  • To evaluate the indications, surgical techniques, and patient outcomes for the transcochlear approach in treating petroclival tumors.
  • To assess the efficacy and safety of this surgical method.

Main Methods:

  • Retrospective review of 24 cases of petroclival tumors treated between 1985 and 1995.
  • Analysis of surgical techniques, including single- or two-stage procedures and the use of a middle fossa transpetrous approach for second-stage surgeries.

Main Results:

  • Meningioma was the most frequent diagnosis.
  • Complete tumor removal was achieved in 82% of cases with an average follow-up of 36 months.
  • Temporary facial nerve dysfunction occurred in most patients, with 60% improving to House-Brackmann Grade III or better; 59% experienced permanent neurologic sequelae.

Conclusions:

  • The transcochlear approach is indicated for intradural petroclival tumors extending ventrally to the brainstem in patients with non-serviceable hearing.
  • Temporary facial nerve weakness is an expected outcome due to nerve transposition, necessitating careful patient selection and counseling.
