[1] Indications include unilateral hearing loss (85%), speech impediments, disequilibrium, tremors or other loss of motor control.
The translabyrinthine approach is a surgical approach to treating serious disorders of the cerebellopontine angle, (CPA), which is the most common location of posterior fossa tumors. especially acoustic neuroma.
