ETV is a well established and successful method in contemporary neurosurgery. With
growing experience there is a more efficient patient selection and further advances
in technical know how. We evaluated retrospectively a consecutive group of 27 patients
who were treated in our institution by stereotactic guided ETV between 1992 and 1996.
When reviewing their postoperative imaging studies (MRI/CT) we could measure the position
of the burr hole as port of entry for the rigid endoscope in 17 out of 23 finally
selected patients. The median lateral position was 28 mm (mean 26.5 mm) from the midline
and 8 mm (mean 6.5 mm) anterior of the coronal suture. We conclude that the optimal
burr hole position should be 3 cm lateral to the midline and 1 cm anterior of the
coronal suture, in the patients with normal anatomical findings.
