COMPARATIVE ANALYSIS OF COLD CURETTAGE AND COBLATION ADENOIDECTOMY: SURGICAL AND POSTOPERATIVE OUTCOMES WITH 0° AND 70° ENDOSCOPIC TECHNIQUES

A total of 128 pediatric patients aged 3-11 years who underwent adenoidectomy between August 2024 and August 2025 was prospectively evaluated with a follow-up duration of 6-12 months. (Table 1) Of these, 64 underwent adenoidectomy and/or myringotomy with ventilation tube insertion using the conventional cold curettage method, while the remaining 64 underwent the same procedures using the endoscopic coblation technique with 0° or 70° endoscopes. All patients had been diagnosed with adenoid hypertrophy and were unresponsive to medical treatment. Indications for surgery included nasal obstruction and associated symptoms such as snoring, apnea, mouth breathing during sleep, recurrent otitis media, and hearing loss due to serous otitis media.

Exclusion criteria included patients who underwent concurrent tonsillectomy, dental procedures, or nasal surgeries such as septoplasty and/or turbinate reduction. Patients with chronic neurological disorders or cleft palate were also excluded. Informed consent was obtained from all participants prior to inclusion in the study.

All patients underwent a detailed anamnesis and clinical examination. Following the application of a nasal decongestant spray, nasal endoscopy was performed, and the size and position of the adenoid tissue were scored from 1 to 4 using the McMurray and Clemens scoring system.4 In patients who were uncooperative or for whom endoscopic examination could not be performed, lateral nasopharyngeal radiographs were taken to allow for grading. During the operation, the size and extent of the adenoid tissue were confirmed transnasally or transorally using 0° or 70° rigid endoscopes.
