Preoperative skin tumours thickness determination by high-frequency ultrasound on head and neck region

Abstract

Background  High-frequency ultrasound is non-invasive imaging method for examination of skin tumours.


Objective  The aim of our study was to examine validity of 20-MHz ultrasound in preoperative determination of skin tumour thickness localized on head and neck region as a potentially useful tool for planning of the surgical intervention.


Methods  Seventy-three different skin tumours were preoperatively examined using Dermascan C (Cortex Technology, Denmark) 20-MHz ultrasound equipment. Maximal vertical thickness of tumours was preoperatively determined by ultrasound, and after surgical excision of tumours, on pathohistological preparations using Nippon–Kogaku ocular micrometre. All patohistological specimens ...
