title: Lorenz Heister and the challenge of trepanation: a neurosurgical case study from the 18th century.
abstract: In the 18th century, medical practice was essentially based on communication. Cranial trepanation, however, was usually performed on an unconscious person. Here the dialogue ceased. It was the only operation which had to be attempted without the positive consent of the patient. Thus trepanation challenged the surgeon's skill not only with its intricate surgical practice, but also with its unusual social setting. The present paper illustrates possible ways out of the "trap of trepanation" by interweaving two points of view. On the one hand, a general account is given on the basis of surgical publications written by Lorenz Heister and his contemporaries. On the other, the unpublished sources of the Heister correspondence serve to reconstruct the case of Heinrich Wilhelm Bachmann, a German merchant who fell victim to a traffic accident and underwent trepanation in 1753. The case study shows how the physician in charge counterbalanced the patient's inability to communicate by strengthening the remaining network of professionals, and ultimately confirming his decisions by use of the post-mortem.
