Letter: Craniometrics and Ventricular Access: A Review of Kocher's, Kaufman's, Paine's, Menovksy's, Tubbs', Keen's, Frazier's, Dandy's, and Sanchez's Points.

To the Editor: In their recent article, “Craniometrics and Ventricular Access: A Review of Kocher’s, Kaufman’s, Paine’s, Menovksy’s, Tubbs’, Keen’s, Frazier’s, Dandy’s, and Sanchez’s Points” Morone et al1 provide an excellent overview of the various methods of obtaining ventricular access based on different cranial starting points and drain trajectories. As the authors expertly illustrate, Kocher’s point is the most common starting cranial location and is used in the vast majority of cases, especially for emergency external ventricular drain (EVD) placement. We agree with the authors that the other cranial points of access are most commonly used intraoperatively when the entry point is limited by the exposed surgical field. The authors should be commended for their
