We are well aware that some neurosurgeons occasionally perform ventriculographic examination through frontal burr holes;1 however, the numerous advantages of the method have not been sufficiently stressed and it does not at present enjoy the widespread use it deserves. For this reason the following note is submitted.
Since ventriculography was first described2 the method of choice for ventricular puncture in most clinics has been to make a parietooccipital opening in the skull3 and to insert the brain cannula into the ventricular system either in the posterior horn or at the junction of the posterior horn with the body. Difficulties met with in this procedure may be enumerated as follows:
1. The posterior horn in normal persons varies considerably in size. In some cases it may even be absent. Numerous cannula punctures may be necessary before the ventricle is reached.
2. The cannula may enter the glomus of
