Objective:Analyze the clinical features in children with pharyngeal neoplasm, and explore the clinical efficacy of low-temperature plasma minimally invasive treatment in children with pharyngeal neoplasm. Methods:A total of 46 pediatric cases of pharyngeal neoplasms admitted to the Otolaryngology Department of Wuhan Children's Hospital from January 2016 to December 2023 were included. There were 23 males and 23 females, with admission ages ranging from 5 days to 9 years and 4 months, and a median age of 2 years and 2 months. The clinical manifestations, examinations, treatments, and outcomes were evaluated. Results:Among the 46 pediatric patients, 21 were admitted with throat wheezing, 7 with masses in the oropharynx or head and neck, 5 with dyspnea, 4 with snoring during sleep as the main symptom, 3 with hoarseness, 2 with sore throat, 2 with swallowing discomfort, and 2 with difficulty feeding as the first symptom. Comorbidities included 5 cases of combined laryngomalacia, 4 of snoring, 4 of congenital heart disease, 4 of severe pneumonia, 3 of myocardial damage, 1 of multiple deformities, and 1 after hematopoietic stem cell transplantation. All patients underwent CT or MRI examination, with 26 cases undergoing local ultrasound examination and 39 undergoing electronic laryngoscopy examination. A total of 19 patients were transferred to the ICU after surgery, all of whom were patients with pharyngeal cysts. All patients underwent low-temperature plasma minimally invasive surgery, and all patients were diagnosed through pathological examination, including 1 case of nasopharyngeal teratoma, 5 of pharyngeal non-Hodgkin's lymphoma, 1 of oropharyngeal rhabdomyosarcoma, 1 of laryngeal perivascular epithelioid cell tumor （PEComa）, and 38 of pharyngeal cysts （2 cases of uvula, 2 of oropharynx, 7 of epiglottic valley, 19 of tongue base, 2 of branchial cleft cyst, and 6 of throat）. Conclusion:Pharyngeal neoplasms in children are prone to upper airway obstruction, including some rare or malignant tumors. Imaging and pathological diagnosis can assist in early diagnosis. Depending on the nature of the tumor, early detection and treatment can improve the quality of life and survival rate of children. Low-temperature plasma radiofrequency ablation is safe, minimally invasive, precise, and provides a clear field of vision, making it a valuable treatment option for children with pharyngeal neoplasms.
