Table 1: 
Indications, benefits, and disadvantages of lateral skull base approaches for VS resection
TranslabyrinthineRetrosigmoidMiddle Fossa
IndicationsUnserviceable hearing; any IAC or CPA VSVS with large CPA component; medial IAC VSSmall lateral IAC VS (<0.5 cm); small medial IAC VS with <1 cm CPA component
AdvantagesMinimal brain retractionPanoramic CPA exposure; better facial nerve and hearing preservation for medial VSBetter exposure, lateral IAC
DisadvantagesComplete hearing loss; difficult approach for CPA VS ventral to porus acusticus; risk for facial nerve injuryLimited access to lateral IAC; potential for cerebellar and brain stem injuryLimited PF access; temporal lobe retraction; risk for facial nerve injury
