Abstract
The object of this study was to evaluate the usefulness of preoperative transbuccal ultrasound (US) for the evaluation of tongue tumors. Thus, we evaluated the correlation between preoperative US measurements and postoperative pathologic measurements of tongue tumor size. From January 2003 to March 2011, 29 patients with tongue tumors were evaluated. All patients underwent preoperative transbuccal US at 1 day before surgery. Preoperative US was compared with pathology findings, including specimen size. The maximum anterior-posterior (AP) diameter of the long axis of the tumor, the maximum width (WD), and the maximum thickness (TH) of the tumor were measured with US along with a pathologic evaluation of the specimens. The mean AP was 22 ± 1 mm; WD was 13 ± 6 mm, and TH was 10 ± 5 mm using US. The pathologic mean AP was 21 ± 12 mm; WD was 12 ± 6 mm, and TH was 9 ± 4 mm. The Spearman's correlation coefficients of the AP, WD, and TH were 0.905 (p < 0.001), 0.918 (p < 0.001), and 0.971 (p < 0.001), respectively. Transbuccal US is a useful tool for predicting tongue tumor extent.
