Abstract

Objective:

We describe in detail the technique of in vivo endolaryngeal ultrasound during microlaryngoscopy, offering a number of practical suggestions which may be of use, especially to the otolaryngologist.

Methods:

Endosonography is a non-invasive imaging technology usually applied for the assessment of local tumour growth and regional lymph node metastases in the digestive tract.

Conclusions:

Due to a penetrating depth of up to 25 mm and a high tissue resolution, endosonography also qualifies for use in the larynx. The technique may have a potentially important role in the intra- and post-operative investigation of laryngeal lesions bigger than 3 mm.
