Lateral optico-carotid recess as an anatomical landmark for optimal endoscopic optic nerve decompression.

ABSTRACT:

Background

Transnasal endoscopic decompression of the optic nerve is increasingly gaining acceptance among ear, nose, and throat (ENT) surgeons, however neither strict indications for the procedure nor the precise extent of effective decompression have been firmly established to date. This study aimed to determine the distance between endoscopically visible, anatomical structures within the sphenoid sinus and the posterior (i.e. intracranial) endpoint of decompression. The lateral optico-carotid recess (LOCR) is proposed as a reference for the undertaken measurements.

Methods

The precise localizations of the LOCR and the point at which the optic nerve is covered by bone only for 180° of its circumference were determined using high-resolution computed tomography performed in
