THREE-DIMENSIONAL ULTRASOUND OF THE HEAD AND NECK
Abstract
Background. Only few reports have been published about the use of the three-dimensional ultrasound in the field of otorhinolaryngology. With conventional ultrasound investigation usually enough information can be obtained. One of the most important ultrasound applications in otorhinolaryngology is investigation in patients with head and neck tumors to establish the extent of metastatic disease.
Methods. In the article we present our experience with threedimensional ultrasound. We used it in patients with head and neck tumors, where we established the volume of lymph nodes and their relations to the carotid artery and jugular vein. We also established the volumes of the oral cavity tumors and made a comparison with the T cathegory of TNM classification of malignant tumors.
Results and conclusions. The average size of all tumors was 9,6 cm3. We found the significant correlation between the tumor volumes and T cathegory (p < 0,05).
Despite the fact that not all tumors in the field of otorhinolaryngology are accesible for the ultrasound investigation, we think that the tumor volume could be an important parameter in the treatment of patients with head and neck tumors. Three-dimensional ultrasound offers us also better possibilities to recognise the metastatic infiltration of major vessels on three orthogonal planes.
One of the important advantages of three-dimensional ultrasoun is also in the possibility of digital recording of the obtained data.
