[Chemical content analysis of specimens of human head temporal portion commercially distributed for otological surgery lessons].
Specimens of the human head temporal portion are provided in the United States and distributed commercially for lessons in otological surgery via the internet. Many otologists have obtained and used these specimens in Japan. According to our chemical content analysis, these specimens were found to contain harmful substances as well as large molecule aldehydes and fatty acid methylesters, which are not or only rarely included in the human cadaveric specimens prepared in Japan. We discuss the suggested treatment of these imported specimens, how trial preparation of specimens are much better than the imported items, and the background of the rapid and wide distribution of the imported items in Japan.
