“…Parmar et al 21 reported that elastographic imaging modalities may provide information to assess bones for bone healing. Schmalzl et al 22 reported that US elastography helps to evaluate the tissue elasticity by applying mechanical stress. Shear wave US elastography provides a quantitative measurement of tissue elasticity.…”

We investigated the sonoelastographic features of the lower lateral nasal cartilage lateral crus (LLNC-LC), auricular conchal cartilage (ACC), and costal cartilage (CC). In this prospective study, group 1 consisted of 60 participants (30 males and 30 females) between 18 and 35 years of age. Group 2 consisted of 60 participants (30 males and 30 females) between 35 and 50 years of age. Strain elastography (SE) and shear wave elastography (SWE) were performed. For all LLNC-LCs and ACCs, type I SE was detected more in group 2, type II SE was detected more in group 1, and type III SE was detected more in group 1 (p < 0.05). For CC, type I SE was detected more in both groups (p < 0.05). For LLNC-LC, type I SE was detected more in males compared with females in both groups (p < 0.05). For all LLNC-LC, ACC and CC, the SWE modulus of group 2 was significantly higher than that of group 1 (p < 0.05). In older participants, the SWE modulus increased. We recommend using ACC mainly in rhinoplasty operations for primary and revision cases as its SWE modulus is similar to that of the LLNC-LC. However, due to the higher SWE modulus of CC, CC grafts should not be used as the first choice in rhinoplasties, especially in the reconstruction of the nasal tip contour, but may be used in nasal dorsum augmentation.

“…In addition, the musculoskeletal mode was preset. The tip of transducer covered with several millimeters of ultrasound gel was placed smoothly to the targeted area of the MD along perpendicular direction to the skin [9,13]. It was of importance to ensure that there was no pressure between skin and the probe.…”

Background: To measure the middle deltoid (MD) muscle elasticity during different shoulder abduction in healthy participants using shear wave elastography (SWE) and analyze the factors that may affect the MD elasticity, and then to establish the reference ranges of the normal MD elasticity during different shoulder abduction. Methods: Mean shear wave velocity (SWV) of the MD in 70 healthy participants were evaluated at left and right shoulder 0° and 90° abduction (L0°, R0°, L90°, R90°) using SWE, and potential factors that may affect MD elasticity including gender, MD thickness, age, body mass index were analyzed. Normal reference ranges of MD elasticity were calculated using normal distribution method. Results: Mean SWV was statistically significantly higher at L90° than L0°, higher at R90° than R0°, higher at R0° than L0°, and higher at R90° than L90° (all p< 0.0001). Mean SWV was significantly higher in males at both L0° (p< 0.05) and R0° (p< 0.01) than in females. Neither MD thickness, age nor body mass index influenced MD elasticity. Normal reference ranges of the MD elasticity were 2.4-3.1 m/s in males and 2.2-2.9 m/s in females at L0° and 2.5-3.3 m/s in males and 2.4-3.2 m/s in females at R0°, and were 4.9-6.7 m/s at L90°, 5.2-7.1 m/s at R90° for both males and females. Conclusions: Our results suggest that the normal MD elasticity at L0°, R0°, L90°, R90° are different and gender should be considered when determining the reference ranges of normal MD elasticity at L0° and R0° with SWE. These values may provide quantitative baseline measurements for assessment of the normal MD elasticity.

“…Thirdly and most importantly, the clinical signi cance of establishing reference ranges of normal MD elasticity lies in providing preliminary exploration for serving as the baseline measurement of normal MD elasticity. Using this new ultrasound elastography technique SWE, the reference ranges of normal MD elasticity have hardly been studied before [29][30]. If reference ranges of normal MD elasticity can be generalized to a larger healthy population in the future, the clinical signi cance will be even greater.…”

Background: To measure the middle deltoid (MD) elasticity in healthy participants during different shoulder abduction (with bilateral shoulder in 0 degree abduction and 90 degree active abduction) using shear wave elastography (SWE) and analyze the factors that may affect the MD elasticity, and the objective of this study is to establish the reference ranges of normal MD elasticity during different shoulder abduction by using SWE. Methods: Mean shear wave velocity (SWV) of the MD in 70 healthy right-handed participants (35 females, 35 males) were evaluated using SWE during different shoulder abduction, and potential factors that may affect MD elasticity including gender, MD thickness, age, body mass index were analyzed. Different shoulder abduction positions of each participant were as follows: (i) 0° abduction of bilateral shoulder (L0° and R0°), (ii) 90° active abduction of bilateral shoulder (L90° and R90°). Reference ranges of normal MD elasticity were calculated using normal distribution method. Results: Mean SWV was significantly higher at L90° than L0°, higher at R90° than R0°, higher at R0° than L0°, and higher at R90° than L90° (all p< 0.0001). Mean SWV was significantly higher in males at both L0° (p< 0.05) and R0° (p< 0.01) than in females. Neither MD thickness, age nor body mass index influenced MD elasticity. Normal reference ranges of the MD elasticity were 2.4-3.1 m/s in males and 2.2-2.9 m/s in females at L0° and 2.5-3.3 m/s in males and 2.4-3.2 m/s in females at R0°, and were 4.9-6.7 m/s at L90°, 5.2-7.1 m/s at R90° for both males and females. Conclusions: Our results suggest that the normal MD elasticity at L0°, R0°, L90°, and R90° with SWE are different. A separate reference range of normal MD elasticity at L0°, R0°, L90°, and R90° should be used. Moreover, the reference ranges of normal MD elasticity at L0° and R0° shoulder be divided by gender. These values may serve as quantitative baseline measurements for assessment of normal MD elasticity.
