Abstract: Objective To study the imaging characteristics of subcutaneous benign tumors in the face and neck of children,as well as the feasibility,efficacy,and safety of minimally invasive treatment of subcutaneous benign tumors in the head and neck of children through hair area or axillary soft tissue endoscopy．Methods A retrospective analysis was conducted on 24 cases of subcutaneous tumors in the face and neck of children treated in our hospital from January to August 2024．Age range was 1-5 years old,with an average of 1.5 years old．There were 15 boys and 9 girls．There were 10 cases of thyroglossal duct cyst,5 cases of branchial fistula,5 cases of subcutaneous mass on the forehead,3 cases of enlarged cervical lymph nodes,and 1 case of subcutaneous mass on the neck．Imaging characteristics（ultrasound and CT examination）and minimally invasive treatment effects were analyzed,to determine the procedure of minimally invasive treatment of subcutaneous tumors in the forehead and cervical lymph node biopsy by soft tissue endoscopy in the scalp area,and minimally invasive treatment of thyroglossal duct cysts and branchial fistulas through axillary by soft tissue endoscopy．Results The imaging characteristics of subcutaneous benign tumors in children’s face and neck were located in the shallow layer,with clear boundaries,round or oval shapes,mild compression of surrounding tissues,and no invasion．All cases successfully underwent minimally invasive surgery with minimal bleeding,no surgical complications,and good postoperative recovery．Postoperative pathological examination confirmed as benign masses．There were no surgical scars on the face and neck．Conclusions The imaging characteristics of subcutaneous benign tumors in children’s face and neck are located in the shallow layer with clear boundaries．Minimally invasive endoscopic treatment of pediatric face and neck tumors through the scalp area and axillary soft tissue is effective,safe,and aesthetically pleasing．
