Tone evoked BERA for

threshold estimation at

2000Hz done in our

clinic using the

Interacoustics Eclipse

evoked potential

machine using insert

ear phones in a 3 month

old child showing

perfectly normal

hearing. Such a clean

recording even with the

pure tone sound

stimulus and not a click

with very discernable

wave peaks right upto

10dB was possible

because of using the

CHIRP BERAtechnology.

Electrocochleography ECochG

Although Electrocochleography has been around for many years, for much of that time it was an

invasive procedure. With the advent of a peritympanic electrode it no longer is invasive and it is now

a fast and simple test. Since the invasive technique is no longer necessary the ECochG should become

routine within the Neurotologic clinic. The diagnosis of endolymphatic hydrops, through EcochGutilizing a peritympanic electrode rather than the invasive electrode on the promontory, gives us

results that have large amplitudes and good morphology.

Saccade test as recorded by VNG:-

The green line is the target and the red

line is the movement of the right eye and

the blue line that of the left eye. The top

box records the movement of the eyes in

the horizontal axis and the bottom boxthat in the vertical axis. The latency,

velocity and precision of eye movements

are calculated and documented

automatically by the high end VNG

machines
