Sigmund Freud’s physicians and “the monster”. Freud received treatment from several physicians – including rhinologists, oro-facial surgeons or radiotherapists – for a cancer of the palate.

This paper provides some details about the physicians who cured Freud and looks at the prosthesis he was forced to wear until his death.
