Visual disturbances after acoustic neuroma surgery are very rare complications. We present a patient with diplopia after a middle fossa approach for resection of an acoustic neuroma. ⋯ It is generally agreed that this reaction is secondary to a dysfunction of the tonic bilateral vestibular inputs that stabilize the eyes and head in a normal upright position in the roll plane. It has also been described after denervation of the utricle and injury of the brain stem.

The aim of the study was to evaluate leakage of liquids in terms of water and artificially produced saliva past low-pressure cuffs of tracheal tubes. ⋯ The present laboratory findings suggest that the three tracheal tubes studied will not guard against aspiration of water but they will prevent the leakage of artificial saliva to a great extent.
