Objective To evaluate the application of palmtop ultrasonography in the treatment of subcutaneous fat hyperplasia associated with insulin injection. Methods The study subjects were 65 patients with insulin injection-related subcutaneous fat hyperplasia in our hospital from January 2023 to December 2023. Palm ultrasound examination and clinical examination were performed for all patients. Palm ultrasound characteristics of insulin injection-related subcutaneous fat hyperplasia were analyzed, and the detection rate of insulin injection-related subcutaneous fat hyperplasia was compared between combined ultrasound and clinical examination. Results Palmtop ultrasound: 15.39% (10/65) of the patients showed no blood flow, no envelope and disappeared skin boundary. 66.15% (43/65) of the patients had uniform blob hyperechos without blood flow, envelope and boundary ambiguity. The boundary is not clear, and 6.15% (4/65) of high echo clusters contain low echo regions. The ultrasonography showed no blood flow, no envelope, less uniform echo and unclear boundary in 6.15% (4/65). The thickness of the simple fat layer was 6.15% (4/65), which was thicker than the fat layer near the normal fat layer or the fat layer without insulin injection in the symmetric site. Of the 65 patients, 45 (69.23%) found insulin injection-related subcutaneous fat hyperplasia by clinical examination, and 63 (96.92%) found insulin injection-related subcutaneous fat hyperplasia by ultrasound examination. The detection rate of handheld ultrasound was higher than that of clinical examination (χ²=14.717, P=0.000). The combination of the two screening methods could further improve the detection rate of insulin injection-associated subcutaneous fat hyperplasia [100.00% (65/65)]. Conclusion The application of palmtop ultrasonography in insulin injection related hyperplasia of subcutaneous fat is significant and can be popularized.
