Abstract

Objective:

To introduce the use of optical coherence tomography with an operating microscope for intra-operative evaluation of the human larynx.

Methods:

A specially equipped operating microscope with integrated spectral domain optical coherence tomography apparatus was used during microlaryngoscopy.

Results:

Technical improvements in optical coherence tomography equipment (e.g. pilot beam, variable focal distance, improved image quality and integration into an operating microscope) have enabled greater sensitivity and imaging speed and a non-contact approach. Spectral domain optical coherence tomography now enables a better correlation between optical coherence tomography images and histological findings. With this new technology, the precision of biopsy can be improved during microlaryngoscopy.

Conclusions:

Use of this new optical coherence tomography technology, integrated into an operating microscope, enables the surgeon to define the biopsy site location and resection plane precisely, while the optical zoom of the operating microscope can be used over the complete range.
