Abstract:
BACKGROUND: Skull trepanation is an ancient art and has been recognized in many, if not most, primitive societies. Papua New Guinea came into contact with Europeans in the late 1800s and therefore it was possible for the art to be documented at a time when cranial surgery in Europe was still in its infancy. METHODS: A reviewof published articles and accounts of those who observed skull trepanation or spoke to those who had. Review of a video of trepanation as practised today in Lihir. FINDINGS: Richard Parkinson was a trader turned amateur anthropologist who was able to observe the surgical procedure being practised in Blanche Bay (New Britain). Trepanation was also witnessed by Rev. J.A. Crump in the Duke of Yorks. In New Britain the operation was performed for trauma but in New Ireland it was also employed on conscious patients for epilepsy or severe headache, particularly in the first five years of life. There was, however, a tendency to operate on frontal depressed and open fractures, rather than temporoparietal ones. Once the decision to operate was made the wound was irrigated in coconut juice and this was also used to wash the hands of the surgeon. Anaesthesia was not required as the traumatized patient was unconscious. The procedure is described and the tools included local materials such as obsidian, shark's tooth, a sharpened shell, rattan, coconut shell and bamboo. Of particular interest is the observation of brain pulsations and their relationship to a successful outcome. ASSESSMENT: The outcomes were good, in that 70% of patients were thought to survive, contrasting with a 75% mortality for cranial surgery in London in the 1870s. There is supporting evidence in that many trepanned skulls show evidence of healing and life long after the procedure was completed. Other societies have reported similar survival rates. The good outcomes may have been due to wise case selection as well as a high level of surgical skill following sound principles of wound debridement without necessarily being able to drain a haematoma.
