Учебники / Middle Ear Mechanics in Research and Otology Huber 2006

Insummer2006,the4thInternationalSymposiumonMiddleEarMechan-

ics in Research and Otology was held at the University of Zurich, Switzer-

land. More than 250 participants from 33 countries of all five continents

came together to present their newest results of research, to exchange their

knowledge in practical applications, to discuss open questions and to dis-

cover new unsolved problems.

Thisbookincludesrepresentativeandselectivearticlesoflecturesand

papers held during the symposium and thereby gives an overview of the

ongoingresearchandcurrentknowledgeinfunctionandmechanicsofthe

normal, diseased and reconstructed middle ear. It covers basic research,

engineering and clinical aspects of evaluation, diagnosis and surgery of

the middle ear as well as implantable hearing devices. These subjects have

been discussed in a very broad and interdisciplinary way between the par-

ticipants. The 44 contributions went through a peer review process by the

scientific committee.

After this fourth meeting of experts in a successful and developing

series, this book follows the tradition of the organizers of the previous

conferencestocollectthecontributionsof thesymposium.The1st sympo-

sium was held 1996 in Dresden and was initiated by K.B.Hüttenbrink, the

v

2nd symposium was organized by S.N.Merchant and J.J.Rosowski 1999

in Boston and the 3rd symposium was held 2003 in Matsuyama, arranged

by K.Gyo and H.Wada. We are proud to continue these series and to add

a collection of current and interesting contributions presented and dis-

cussed intensively in Zurich during MEMRO 2006.

and to create new ones. We are very grateful to all helpers, institutions and

sponsors that made this symposium so successful. Our special thanks go
