“…Helbig et al reported a series of five cases in which sonographic images were used to visualize the deep margin, and a braided surgical suture was used to mark a 1‐ to 2‐mm distance from the deep margin of the tumor and aid the planning of the surgical resection . Baek et al conducted a prospective study on a cohort of 20 patients with clinical T1‐2 oral tongue cancer who received US‐assisted glossectomies and compared them to a group of T‐stage–matched controls who received conventional resection at their institution . A point 1.5 cm off the deep margin was marked with a needle under sonographic guidance to provide a reference point for the surgeon.…”

Objectives: To demonstrate the usefulness of intraoral ultrasonography (IOUS) for tongue mass lesions, we analyzed surgery cases excluding squamous-cell carcinoma and leukoplakia and compared IOUS and pathological findings. Methods: We used the hospital information system and Radiology Information System to evaluate the IOUS and pathological findings of patients who underwent surgeries for tongue masses in the past 11 years. Results: Surgeries for the tongues were performed in 268 cases. Imaging examinations were carried out in 52 (19.4%) cases including 42 (15.7%) cases by IOUS. The pathological results of the surgeries were as follows: 36 cases were inflammatory lesions, 74 cases were tumours, 131 cases were hyperplasia, 8 cases were cystic lesions and 19 cases were other miscellaneous lesions. On the other hand, the number of patients who received IOUS in the same period was 87, and 42 of them had surgeries. In 32 out of the 42 (76.2%) cases, pre-operative IOUS features matched with pathological results. Most of the haemangiomas and lipomas could be diagnosed by IOUS alone. Conclusions: IOUS of the tongue revealed the nature of the lesions including the border, size, location, depth, the presence or absence of a capsule and the internal structure including vascularity of the mass. The ultrasonographic findings well reflected the histological findings. IOUS is a simple and useful technique that provides additional information beyond inspection, clarifying the internal structure, blood flow and relationships with the adjacent tissues. In this article, we indicated 11 representative cases (fibrous polyp, haemangioma, pyogenic granuloma, lipoma, liposarcoma, chondroma, lymphangioma, schwannoma, neurofibroma, pleomorphic adenoma and amyloidosis) to show the usefulness of IOUS.

“…US can be used as a preoperative noninvasive tool with which to assess the histological structure of tongue cancer [2,[5][6][7][8][9][10][11][12][13][14]. Hayashi [15] reported that US should be routinely used as a standard technique to evaluate the depth of tumor invasion.…”

“…Preoperative ultrasonography (US) assessment is useful to noninvasively predict the prognosis of tongue cancer [2,3]. Some reports have demonstrated the usefulness of intraoral US for delineating the shape of the tumor margin, internal echo signal, tumor extent, and depth of invasion [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17]. US images reflect the histological structure of tongue cancers, even superficial carcinomas [2,[5][6][7][8][9][10][11][12][13][14].…”

Objectives To evaluate the feasibility of using ultrasoundobtained tumor depth (TD) and margin shape (MS) to predict the prognosis of tongue cancer. Methods Fifty-two Japanese patients with tongue cancer who underwent ultrasound examination between 2007 and 2012 were retrospectively evaluated. TD was measured at the deepest portion of the tumor. MS was classified as ''pressure,'' ''wedge-shaped,'' or ''permeated.'' Prognosis was assessed by local recurrence, lymph node metastasis, and overall survival rate. We classified the patients into a good prognosis group and poor prognosis group. Relationships among TD, MS, and patient prognosis were evaluated using Spearman rank correlation. A regression formula to predict prognosis using TD and MS was derived.Results The correlation between TD and MS was significant (Spearman rank correlation q = 0.552, p \ 0.01).Using a structure matrix, we identified the contribution of both predictors from an ultrasound image. The contribution of TD was 0.796, while that of MS was better at 0.906. The prognosis could be predicted using the following regression formula: D ¼ À2:801 þ 0:093x þ 0:872y, where D prognosis (risk probability), x = TD (mm), and y = MS (grade). The average value for good risk probability was -0.254 (standard deviation, 0.962), while that for poor risk probability was 0.566 (standard deviation, 1.08) (p \ 0.05). The cut-off value for classifying cases was -0.00169. Using the formula above, 73.1 % of patients in the poor prognosis group were correctly classified.Conclusions MS and TD are useful predictors of tongue cancer prognosis.
