RESUMEN
This book is a compilation of several articles published over many years. The articles deal with three surgical methods and several techniques which I have devised. These discoveries and their technical publication were not the result of chance but of a methodical and orderly system of work about which I shall give and account. This book has been written based on the pre-Columbian cultures of South America. From these cultures peoples and nations have come about, grown, become strengthened and flourished, intellectually and culturally. All the chapters in the book describe methods and discoveries made and developed by us in South American hospitals. Most chapters include a photograph of a pre-Columbian ceramic figure as prologue, each one with its own description. The figure on the cover shows facial paralysis and is described in the first page of the book.
