Abstract

Background: The treatment of adenoid hypertrophy in children has long been recognized as a common and clinically significant issue that requires timely intervention to prevent complications and ensure normal growth and development. Coblation adenoidectomy utilizes low-temperature radiofrequency energy to ablate and coagulate soft tissue, allowing precise removal with minimal thermal injury, reduced intraoperative blood loss, and decreased postoperative pain. Objectives: To describe the clinical and paraclinical characteristics of pediatric patients with adenoid hypertrophy indicated for surgery and to evaluate the outcomes of endoscopic coblation adenoidectomy. Materials and methods: A prospective single-arm interventional study was conducted on 68 pediatric patients who underwent endoscopic coblation adenoidectomy at Can Tho Ear Nose Throat Hospital between April 2024 and June 2025. Results: There was no statistically significant difference in sex distribution between males (48.53%) and females (51.47%). Rhinorrhea was the predominant presenting symptom (85.29%). Grade III adenoid hypertrophy was most common (66.18%), and otitis media with effusion was identified in 29.41% of patients. Isolated adenoidectomy was performed in 73.53%, while 26.47% underwent concomitant otorhinolaryngologic procedures. A case of bleeding at the surgical site was noted one week postoperatively. The proportion of pediatric patients who were pain-free increased from 44.12% on postoperative day 1 to 70.59% on day 2, reaching 100% by day 7. Favorable outcomes were achieved in 97.06% of patients. Conclusion: Endoscopic coblation adenoidectomy demonstrated safety and effectiveness, with shorter operative time, reduced intraoperative blood loss, decreased postoperative pain, and favorable postoperative outcomes.
