“…Many of the studies about ultrasound in medical education address the benefits of using it to supplement the teaching of anatomy (Tshibwabwa and Groves, 2005;Ivanusic et al, 2010;Swamy and Searle, 2012;Dreher et al, 2014;Jurjus et al, 2014;Moscova et al, 2015;So et al, 2017). Specific areas of anatomic instruction where ultrasound has been described as a useful tool include cardiovascular, musculoskeletal, and head/ neck anatomy (Wittich et al, 2002;Tshibwabwa et al, 2007;Griksaitis et al, 2012;Hammoudi et al, 2013).…”

More emphasis is now being placed on active learning in medical education. Ultrasound is an active learning tool that can be used to supplement didactic instruction. This study describes a self‐guided activity for learning floor of mouth ultrasound. Thirty‐three first year medical students learned floor of mouth scan technique and ultrasound anatomy through a brief PowerPoint module. They subsequently performed the scan on a standardized patient. Each student was asked to label the floor of mouth muscles on the image he or she acquired. After the activity, the students were given a quiz on anatomic relationships of the floor of mouth. Perceptions about the activity were collected through a survey. All 33 students obtained a floor of mouth image within a three minute time limit. Twenty‐four (73%) students were able to completely and accurately label the image in time. The mean score on the muscle relationships quiz was 93%. Overall perceptions were very positive with most students expressing a “high” or “very high” level of interest in incorporating similar self‐guided activities within the curriculum. This study showed that it is feasible for students to learn scan technique and recognize relevant ultrasound anatomy in an independent fashion through a brief active learning module. Furthermore, the students found the activity enjoyable. The implication is that similar activities could be developed which would provide additional ways to incorporate active learning strategies.

Tongue sonography: An introduction

Sonography has long been recognised as the primary imaging modality in the evaluation of thyroid, parathyroid, nodal, and salivary gland pathologies. Since the late 1980‐2019's, the literature has described an evolving role for ultrasound in the assessment of the tongue and the floor of mouth. Ultrasound can be used for tumour staging, vascular malformations, and for the evaluation of tongue movement during phonation and in the sleep cycle. This article aims to introduce the sonographer to the basic technique, sonographic anatomy, and commonly encountered abnormalities of tongue ultrasound. It has been divided into three key sections: Anatomy, Function, and Physiology; ultrasound technique (Transcervical/Intra‐oral); common pathology.

“…Currently, ultrasound is the most routine clinically applied modality used to address the in-depth involvement of tumors in an interventional setting (15). This same technology is also routinely applied to mark suggestive lesions for the surgeons' convenience using, for example, guidewires, radioactive iodine seeds, or imaging tracers (16,17).…”

Three-Dimensional Tumor Margin Demarcation Using the Hybrid Tracer Indocyanine Green-^99mTc-Nanocolloid: A Proof-of-Concept Study in Tongue Cancer Patients Scheduled for Sentinel Node Biopsy

et al. 2018

For radical resection of squamous cell carcinoma of the oral cavity, a tumor-free margin of at least 5 mm is required. Unfortunately, establishing in-depth margins is a surgical conundrum. Knowing that the hybrid sentinel node (SN) tracer indocyanine green (ICG)-99m Tcnanocolloid generates temporary tattoolike markings at the site of administration, we studied the ability to apply this tracer for tumor margin demarcation combined with SN biopsy. Methods: Nineteen patients with clinical T1-T2 oral tongue tumors received the traditional superficial 3 or 4 deposits of ICG-99m Tc-nanocolloid (0.1 mL each), and in 12 patients additional deposits were placed deeply using ultrasound guidance (total of 6; 0.07 mL each). SN mapping was performed using lymphoscintigraphy and SPECT/CT. Before and directly after tumor excision, fluorescence imaging was performed to monitor the tracer deposits in the patient (fluorescent deposits were not used to guide the surgical excision). At pathologic examination, primary tumor samples were studied in detail. Results: The number of tracer depositions did not induce a significant difference in the number of SNs visualized (P 5 0.836). Reproducible and deep tracer deposition proved to be challenging. The fluorescent nature of ICG-99m Tc-nanocolloid supported in vivo and ex vivo identification of the tracer deposits surrounding the tumor. Pathologic examination indicated that in 66.7% (8/12), all fluorescence was observed within the resection margins. Conclusion: This study indicates that tumor margin demarcation combined with SN identification has potential but that some practical challenges need to be overcome if this technique is to mature as a surgical guidance concept. Future studies need to define whether the technology can improve the radical nature of the resections.
