In acoustic neuroma all are seen except -
In Acoustic Neuroma

Loss of corneal reflex is seen – due to the involvement of Tringeminal nerve
Tinnitus – due to pressure on cochlear nerve
Large tumors can cause diplopia

As far as facial nerve palsy is concerned – Scott Brown 7th/ed vol-3 pg 3931
“Vestibular schwannomas, although inevitably grossly distort the VIIth nerve, very rarely present as a VIIth nerve palsy. If there is a clinical evidence of a cerebellopontine angle lesion and if the VIIth nerve is involved, alternative pathology is more likely”.
Hence although Acoustic neuroma may involve the 7 nerve but complete palsy is never seen
Loss of corneal reflex
Tinnitus
Facial palsy
Diplopia
