“…Gritzmann [20] analyzed 302 patients and found a sensitivity of 100 % for the examination in the identification of neoplasms. The results of the study were in accordance with those reported by Millesi et al [28] and Hodder et al [29], who found values over 90 %. Other authors obtained different results; Haberal et al [30] and Anand et al [31] found rates over 70 %, but Hohlweg-Majert et al [32] described a sensitivity of 24.5 % for US.…”

Objective The aim of this study was to evaluate the contribution of ultrasonography in the establishment of the diagnosis of nonspecific nodular lesions of the oral soft tissues. We determined the indication of use and reliability of ultrasonography in the field of dentistry, considering whether it was of value in the conclusive diagnosis of these pathologies. Materials and Methods We recruited 65 patients from the Oral Medicine Unit of São Lucas Hospital, who had submucosal and subcutaneous nodules, without established diagnosis. They were subjected to ultrasonography of the lesion, carried out with standardization of the protocol and equipment, utilizing a Doppler system. The ultrasonographic report was prepared by an experienced professional, noting the imaging characteristics as well as the possibility of diagnosis. Two calibrated examiners analyzed the data, comparing the ultrasonographic report with the final diagnosis. Accordingly, we used established scoring, where zero corresponded to no contribution to the final diagnosis, 1 helped in the management of the case, and 2 when imaging determined the diagnosis. Results A zero score was obtained for 12.3 % of the examinations performed, and 1 and 2 accounted for respectively 41.5 and 46.1 %, totaling a contribution of about 88 %. Ultrasonography was of value in the diagnosis of vascular lesions in 93.3 % and of neoplasms in 87.5 %. In the salivary gland diseases, it contributed to the final diagnosis in 75 %. Conclusion The results demonstrated that ultrasonography is an effective tool in the determination of the definitive diagnosis of nonspecific nodular lesions of the soft tissues of the oral and maxillofacial region.

“…Not only is ultrasound useful for visualizing the complicated anatomy of the head and neck, but it has also become incredibly useful for diagnosis of conditions including lymphadenopathy, cysts, lipomas, carotid body tumors, thyroid malignancy, salivary gland stones and tumors, and tumors of the oral cavity and airway. [24][25][26] In the diagnosis of these conditions, ultrasound-guided fine-needle aspiration is superior in accuracy, cost-effectiveness, and diagnostic value compared to palpation alone and is now considered the reference standard for evaluating conditions such as thyroid nodules. [27][28][29][30][31] Despite its unquestionable utility, it can be difficult for physicians to gain competence because of a lack of universal training, and many complete their otolaryngology residencies without learning basic ultrasound skills.…”

ith the rise in popularity of ultrasound imaging, the demand for effective training tools has exponentially increased. Ultrasound models, or phantoms, are widely popular for facilitating the learning of hand-eye coordination needed for ultrasound imaging and ultrasound-guided procedures. Unfortunately, many available ultrasound models are expensive and have limited life spans. 1 Gelatin is frequently used to create phantoms because of its ease of use and low cost, and gelatin models have been used in fields such as anesthesiology, pain management, general surgery, and medicine. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] For the otolaryngologist, as well as other providers treating head and neck disorders, ultrasound in an invaluable tool for visualizing head and neck structures. It provides an inexpensive, radiationfree way to visualize the airway, identify tumors, assess thyroid nodules, and guide fine-needle aspiration of the salivary glands, lymph nodes, and thyroid. 14,18-20 However, similar to other fields of medicine in which ultrasound is used, training tools for head and neck procedures can be expensive and difficult to acquire. With this factor in mind, we developed 2 simple gelatin-based phantom models that can be used for instruction on fine-needle aspiration technique for the head and neck. TECHNICAL INNOVATIONThe rise in popularity of ultrasound imaging has seen a corresponding increase in demand for effective training tools such as phantom models. They are especially useful for teaching and practice of invasive procedures, such as fine-needle aspiration of lesions of the head and neck. We have created 2 gelatin models out of inexpensive, commonly available materials that can be used in sequence to learn head and neck fine-needle aspiration. Fundamental skills can be learned first on the flat, rectangular model, whereas the second, cylindrical model more closely represents human anatomy and can be used to develop more advanced technique.

“…In the treatment of patients with squamous cell carcinoma of the oral cavity size of primary lesion, site, thickness, histological staging and the presence or absence of metastatic spread are all important to formulate a treatment plan. 2 Invasive squamous cell carcinoma of the upper aero-digestive tract has a strong potential for metastatic spread to the cervical lymph nodes. The presence or absence of nodal metastasis has a great impact on the prognosis and survival of patients with oral cancer.…”

“…Nodal metastasis to one side decreases the survival by 50%, while bilateral metastasis decreases survival by a further 25%. 2,3,4,5 Hence, the neck status is the single most important indicator of prognosis in head and neck cancers. 6 Factors that have been shown to increase the risk of cervical metastasis include the site of the primary tumor, tumor thickness, DNAploidy and tumor growth patterns such as infiltrating margins, perineural spread and angioinvasion.…”

“…Some clinicians and surgeons advocate elective treatment of the neck while others don't. 2 The risk of occult metastasis that is higher than 20% is the most important indication for elective neck treatment. It is possible to reduce the risk of undiagnosed metastasis with accurate imaging techniques and thus probably reduce the number of elective neck treatments.…”
