Main description:

Doctors Pellet, Cannoni and Pech have joined forces to write a masterly work on the subject of otoneurosurgery and tumors of the base of the skull. The anatomic illustrations, derived from their meticulous dissections, are of excellent quality and a credit to the famed tradition of French neuroanatomists of the past. It is evident that the operative techniques described by these surgeons indicate that they have spent a great deal of time in the dissecting-room and that they have completely mastered the temporal bone. A perfect knowledge of the fundamental anatomy of the petrous bone is essential before embarking on the difficult surgical procedures in this region of the brain and base of the skull. Reading this work makes it abundantly clear that the results of this type of sur gery are vastly improved when neurosurgeons and otologists combine their skills. Each of these specialists brings his unique experience and entire knowledge to the operation for the greater benefit of the patient. We wish to congratulate Doctors Pellet, Cannoni and Pech on the publication of this excellent work. March 1990 William F. House, MD William E.
