“…Another important predictor for cytologically confirmed malignancy is the nodal shape, as malignant nodes tend to be more round with a S/L ratio above 0.5 [10,27]. In our study we also found a significantly larger S/L ratio in cytologically malignant nodes than in benign nodes.…”

Ultrasound-guided fine needle aspiration cytology (USgFNAC) is commonly used for nodal staging in head and neck squamous cell cancer (HNSCC). Peripheral vascularity is a described feature for node metastasis. Micro-flow imaging (MFI) is a new sensitive technique to evaluate micro-vascularization. Our goal is to assess the additional value of MFI to detect malignancy in lymph nodes. A total of 102 patients with HNSCC were included prospectively. USgFNAC was performed with the Philips eL18–4 transducer. Cytological results served as a reference standard to evaluate the prediction of cytological malignancy depending on ultrasound features such as resistive index (RI), absence of fatty hilum sign, and peripheral vascularization. Results were obtained for all US examinations and for the subgroup of clinically node-negative neck (cN0). USgFNAC was performed in 211 nodes. Peripheral vascularization had a positive predictive value (PPV) of 83% (cN0: 50%) and the absence of a fatty hilum had a PPV of 82% (cN0 50%) The combination of peripheral vascularization and absent fatty hilum had a PPV of 94% (cN0: 72%). RI (threshold: 0.705) had a PPV of 61% (cN0: RI-threshold 0.615, PPV 20%), whereas the PPV of short axis diameter (threshold of 6.5mm) was 59% for all patients and 19% in cN0 necks (threshold of 4 mm). Peripheral vascularization assessed by MFI and absent hilum has a high predictive value for cytological malignancy in neck metastases. Next to size, both features should be used as additional selection criteria for USgFNAC.

“…Okumuş et al . applied ultrasonography and found that the smallest-axis diameters of the submandibular and submental lymph nodes are 1.8 and 2.3 mm ( 14 ). In the present study, the smallest-axis diameters of the submandibular and submental lymph nodes were 2.2 and 3 mm.…”

Background The present study aimed to evaluate the ultrasonographic findings of submandibular and submental lymph nodes in patients with and without odontogenic infection. Material and Methods Systemically healthy patients aged 18-30 years old with or without odontogenic infections were included in this study. Clinical examinations were performed on all patients; those with any odontogenic infection were placed in the study group, and those without were placed in the control group. Ultrasonographic examinations of bilateral submental and submandibular lymph nodes were performed for both groups. The data were statistically analyzed using Pearson’s Chi-square test and Student’s t-test. Results A total of 150 patients voluntarily participated (female: n =86 (57%), male: n =64 (43%)), 75 in the study group and 75 in the control group. During the ultrasonographic examination, patients in the study group had more than one lymph node the same patient was mostly detected, in the study group (right submandibular: n =42, 56%, and left submandibular: n =43, 57.3%). The long-axis diameter of the submandibular lymph nodes was 9.305.30 mm and 5.505.20 mm in the study and control groups, respectively. Conclusions Ultrasonography revealed that the presence, number, and long-axis diameter of the submandibular lymph nodes in the patients with and without odontogenic infection were statistically different. Key words: Odontogenic infection, lymph node, ultrasonography.

“…For example in the study of Bennington et al ., [ 25 ], the thickness was measured at the anteroposterior midpoint of the muscle belly. In our study and the previous studies; measurements were performed at the point of estimated maximum thickness of muscle [ 19 , 20 ]. Bakke et al [ 30 ] also measured the thickness at the anteroposterior midpoint but they estimated the bulkiest level of the muscle.…”

“…It has been reported to be greater in men and elderly individuals [ 21 , 36 ]. In a study conducted by Radsheer et al ., [ 19 ], it was reported that thickness of the masseter muscle decreases with age in both sexes. The similar results were portrayed in studies conducted by Kiliaridis & Kalebo [ 20 ] and Hernandez et al .…”

“…This technique allows the clinician to measure accurately the thickness of the masseter muscle [ 20 , 21 , 24 ]. As a choice of US in determining the MM thickness was guided by the recommendations of previous studies, which described reliability, accuracy and advantages of the ultrasound methods comparing with MRI and CT [ 19 , 20 , 22 , 25 ].…”

Objectives:The purpose of the present study was to examine ultrasonographic appearances of Masseter Muscle (MM) in dentate and edentulous patients without Temporomandibular Disorder (TMD).Materials and Methods: The thickness of the MM in 25 dentate (mean age: 30,68 ± 10,49) and 24 edentulous (mean age: 61,46 ± 9,71) patients, who visited routine dental examination, was measured at rest and at maximum contraction bilaterally. Examinations were performed using an Aloka Prosound α6 (Hitachi Aloka Medical Systems, Tokyo, Japan) equipped with an 8 MHz-wide bandwidth linear active matrix transducer (ranging from 1 to 15 MHz). The visibility and width of the internal echogenic bands of the MM were also assessed and the muscle appearance was classified as I of III types. Type I, characterized by the clear visibility of the fine bands; Type II, thickening echogenicity of the bands; Type III, disappearance or reduction in a number of the bands.Results:MM thickness at rest and contraction in the dentate group were significantly higher than the edentulous group (p <0.05). Type I was the most common echogenic type in both dentate (right:16 (64%), left; 15 (60%)) and edentulous patients (right; 22 (91.7%), left; 18 (75%)). In a dentate group, type II was significantly higher than the edentulous group in both the right and left sides (p <0.05; p <0.01, respectively). Age and gender seemed to have no significant effect on the echogenic type (p ˃0.05).Conclusion:There were significant differences in the thickness at rest and contraction between the dentate and edentulous groups. It was clarified that ultrasonographic features of the MM in dentate and edentulous patients were different.
