description Objective To evaluate the usefulness of intraoral ultrasonography (IOUS) as a tool for predicting neck metastasis. Introduction Squamous cell carcinoma (SCC) of the tongue is aggressive and has a great propensity to metastasize to cervical lymph nodes. SCC of the oral cavity has a worse prognosis when associated with metastatic cervical nodes. Therefore, the metastatic potential of tongue carcinoma should be graded preoperatively to help determine the requirement for neck dissection. Methods Nineteen patients (11 men, 8 women) between 36 and 79 years of age (mean age 60) with T1 to T4a TNM-stage tongue carcinomas were evaluated preoperatively with IOUS. Clinical and pathological TNM classifications were performed. Results The average tumor thicknesses measured using histological sections were significantly ( p

Clinical and pathological TNM classifications were performed. Results The average tumor thicknesses measured using histological sections were significantly ( p  &lt; 0.01) lower than those with IOUS (1.3 vs. 1.6 cm, respectively). A significant correlation was observed between the tumor thickness measured using ultrasonography and that measured using histological sections (pathology). Based on this greater accuracy, the cutoff point of tumor thickness based on IOUS evaluation for predicting neck metastasis was determined to be 1.8 cm. Discussion Some factors may influence neck metastasis. A knowledge of these would help to avoid unnecessary surgical intervention for N0 patients. The results of this study indicates that there is a significant correlation between neck metastasis and tumor thickness. Conclusion Intraoral ultrasonography is useful tool for identifying tongue tumors and measuring their thickness, with the thickness measured by IOUS showing a very good correlation with histological measurements. Moreover, IOUS provides prognostic information prior to surgical treatment since tumor thickness can predict the chance of recognizing metastatic cervical nodes.</description><identifier>ISSN: 0911-6028</identifier><identifier>EISSN: 1613-9674</identifier><identifier>DOI: 10.1007/s11282-010-0051-8</identifier><language>eng</language><publisher>Japan: Springer Japan</publisher><subject>Dentistry ; Imaging ; Medicine ; Oral and Maxillofacial Surgery ; Original Article ; Radiology</subject><ispartof>Oral radiology, 2011-06, Vol.27 (1), p.1-7</ispartof><rights>Japanese Society for Oral and Maxillofacial Radiology and Springer 2010</rights><rights>Japanese Society for Oral and Maxillofacial Radiology and Springer 2011</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c405t-6444499a22d17a946d41e4a08e5addf16079c7f9591bb2786346f9f01a54a1b33</citedby><cites>FETCH-LOGICAL-c405t-6444499a22d17a946d41e4a08e5addf16079c7f9591bb2786346f9f01a54a1b33</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s11282-010-0051-8$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s11282-010-0051-8$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>315,782,786,27931,27932,41495,42564,51326</link.rule.ids></links><search><creatorcontrib>Chammas, Maria C.</creatorcontrib><creatorcontrib>Macedo, Túlio A.
