Objective To investigate the postoperative auditory and facial nerve function
results after cerebellopontine angle meningioma removal.
Design Retrospective chart review.
Setting Tertiary care referral center.
Patients Twenty-one patients undergoing surgical removal of cerebellopontine
angle meningiomas by the senior author (R.J.W.).
Interventions Translabyrinthine or retrosigmoid approach for tumor extirpation.
Main Outcome Measures Postoperative auditory (pure-tone average and speech discrimination
score) and facial (House-Brackmann scale) function within 1 year of follow-up.
Results Twenty-three operations were performed on 21 patients. Hearing preservation
through the retrosigmoid approach was attempted in 11 patients (48%). Normal
hearing (class A) was preserved in 9 of 10 patients. Normal postoperative
facial nerve function (House-Brackmann grade I) was conserved in 11 (65%)
of 17 patients.
Conclusions This review demonstrates that successful hearing preservation is possible
with meningiomas. Therefore, the retrosigmoid approach should be used whenever
serviceable hearing is present preoperatively. Normal facial nerve function
can also be preserved in the majority of patients.
