"otorhinolaryngological"
I do believe he is referring to several orifices. "Oto"= "ear", "Rhino"= "nose", "laryn"= "throat"... you get the point. Ah, I'll have to call my mom and let her know that my nursing knowledge isn't wasting away under a pile of smut.
What I would like to know is, why on earth did Wolfe think that was sexy? I will say that it is good to know that even "major" authors aren't "perfect" at everything they toss their hat at. I think I'll go buy one of his books (not the one in question) just to support his humanity...
