✦ Synopsis

Abstract

Background.

To date, few imaging methods have been established for the head and neck region, in particular for soft tissues, that allow adequate visualization and simultaneously adequate real‐time orientation.

Methods.

We report a new method using a navigated ultrasound device and a navigated surgical instrument that allows—even in the absence of bony landmarks—appropriate visualization and reliable orientation in real time.

Results.

The practical applicability of the system was tested. Good handling and acceptance of the system could be shown. The “3‐dimensional error” derived from the deviations in all 3 dimensions lies at 0.64 mm.

Conclusions.

With this ultrasound‐guided navigated procedure, an accurate approach of soft tissue structures with a surgical instrument is possible. Changes of the situs are represented in real time. © 2007 Wiley Periodicals, Inc. Head Neck, 2008
