Results: RTE demonstrated that the skin of the peri-oral region of patients affected by SSc was stiffer than that of controls, both overall (6;4–6 [median; 25–75th percentile] vs. 11;9–11, p
Conclusion: RTE is a feasible modality to assess peri-oral region skin stiffness with excellent interobserver reproducibility. Further studies on a larger cohort of patients including more clinical data and measures are warranted to confirm our initial results.
Purpose: To evaluate the technical feasibility of real-time elastography (RTE) to assess the stiffness of the skin of the peri-oral region in patients affected by systemic sclerosis (SSc).
Methods: Six female patients affected by SSc (median age = 52 years) presenting with microstomia and six healthy controls matched for age and sex underwent RTE evaluation of the peri-oral region. Two operators with different experience evaluated the stiffness of the peri-oral region placing the probe in four different positions: parasagittal left (PL), parasagittal right (PR), upper axial (UA), lower axial (LA). Color map was converted into a semi-quantitative scale in which blue = 1, green = 2 and red = 3. Thus, each subject had a variable score ranging from 4 (four positions × value = 1) and 12 (four positions × value = 3). Mann–Whitney U and k statistics were used.
