RESUMO
The middle-ear transfer characteristics for sound in 14 human temporal bones were determined using a SQUID magnetometer method. With this method, the cochlea and middle ear remain intact. Postmortem changes were studied using a guinea pig. The mass-loading effects of the applied magnets were determined and were found to be negligible. The mean umbo displacement was equal to the mean of six other studies. Lever ratios varied between the individual temporal bones and as a function of frequency.

The changes in ocular motility in 15 patients with endocrine ophthalmopathy before and after orbital decompression according to Ogura-Walsh are discussed. The conclusion is that decompression of the orbita gives rise to a considerable risk of development or increase of limitations of ocular movements, with diplopia as a result.
