Artificial cranial deformation in Tiwanaku, Bolivia.

Purpose: Herein lies a brief historical review of the practice of artificial cranial deformation (ACD) in Tiwanaku, Bolivia, a pre-Columbian archeological ruin once regarded as one of the most powerful pre-Inca regions whose influence extended into present-day Peru and Chile from 600 to 1000 AD. We describe the history, purpose, and implications of ACD from both a neuroanatomical and cultural perspective.

Methods: A literature review was conducted through PubMed on the history of artificial cranial deformation in South America, concentrating on the Tiwanaku region.

Lessons from failure: neurosurgical outreach in Managua, Nicaragua.

With respect to the tremendous deficit in surgical care plaguing developing nations, it is critical that medical outreach models be organized in such a fashion that sustainable advancements can be durably imparted beyond the duration of targeted missions. Using a didactic framework focused on empowering host neurosurgeons with an enhanced surgical skillset, a mission was launched in Managua, Nicaragua, after previous success in Kiev, Ukraine, and Lima, Peru. Unfortunately, the failure to critically assess the internal and external state of affairs of the region's medical center compromised the outreach mission.
