German physician Saemisch introduced compound lens magnication to medicine in 1876. In the early part of the 20th century, Carl Nylen, a 30-year-old Swedish otolaryngologist, inspired by Maier and Lion’s observations of endolymph movement, conceived and built the world’s first operative microscope. In 1921 he used his monocular microscope for humans for the first time in a case of chronic otitis media.

The original surgical microscopes were crude, usually requiring fixation to the bony structures of the skull 1).
