[Laser doppler interferometry, a new clinical instrument?].
BACKGROUND
In a prospective trial, the diagnostic value of laser Doppler interferometry (LDI) was analysed in the clinical sphere.


METHODS
LDI was compared with standard audiometry for preoperative differential diagnosis of a conductive hearing loss. The intraoperative diagnosis was considered the gold standard.


RESULTS
LDI was applicable in the clinical sphere and allowed, in contrast to standard audiological methods, a statistically highly significant differentiation of middle ear pathologies.


CONCLUSIONS
LDI is a valuable addition to standard audiology for preoperative evaluation of the integrity and mobility of the ossicular chain.
