M. Arriaga et M. Gorum, ENHANCED RETROSIGMOID EXPOSURE WITH POSTERIOR SEMICIRCULAR CANAL RESECTION, Otolaryngology and head and neck surgery, 115(1), 1996, pp. 46-48
A subset of patients with acoustic neuromas and useful hearing have tu
mors that are inadequately approached by both middle fossa and retrosi
gmoid techniques, The enhanced retrosigmoid technique combines the hea
ring preservation of posterior semicircular canal ablation to achieve
lateral internal auditory canal exposure with the ample cerebelloponti
ne angle exposure of the standard retrosigmoid technique.
