Abstract
Abstract The aim of this study was to compare the advantages and disadvantages of the coblation technique with the standard conventional curettage technique in the operation of adenoidectomy in pediatric patients. This was a prospective randomized clinical study. From January 2010 to December 2014, 200 patients presented with obstructive adenoid hypertrophy. Their ages ranged between 3 and 10 years. The patients were classified randomly into two equal groups: group A was subjected to conventional curettage adenoidectomy and group B was subjected to coblation-assisted adenoidectomy. Operative time and intraoperative blood loss were recorded. Patients were scheduled for follow-up on the first day and first and second postoperative weeks. They were asked to record their pain and discomfort on a standardized Wong–Baker faces pain rating scale from 0 (no pain) to 10 (severe pain). Postoperative complications and/or recurrences were also recorded. Follow-up was for at least 1 year, with re-examination of the nasopharynx by means of endoscopy and/or lateral nasopharyngeal radiography. The conventional curettage adenoidectomy group recorded significantly less operative time and the coblation-assisted adenoidectomy group recorded significantly less intraoperative blood loss and also lower incidences of postoperative bleeding and adenoid recurrence. Both groups demonstrated insignificant difference as regards postoperative pain. The use of the coblation technology in adenoidectomy gave more advantage to the procedure with regard to less intraoperative blood loss and lower incidences of postoperative bleeding and recurrence rate.
Highlights
Adenoids, which are a nasopharyngeal lymphoid tissue forming a part of the Waldeyer’s ring, were first described by Meyer in 1868 [1]
The patients were randomly classified into two equal groups: group A was operated upon using the cold curette adenoidectomy (CCA) method, and group B was subjected to coblation adenoidectomy (Co-A)
Group A was subjected to CCA, and group B was subjected to Co-A
Summary
Adenoids, which are a nasopharyngeal lymphoid tissue forming a part of the Waldeyer’s ring, were first described by Meyer in 1868 [1]. Adenoidectomy operation either alone or combined with tonsillectomy and/or myringotomy with ventilation tube insertion has been a target for multiple research studies, to improve its quality and to minimize its side effects and complications, being a common procedure in the field of pediatric otolaryngology [3]. The ideal adenoidectomy procedure should achieve a safe removal of the adenoids with less operative time, blood loss, postoperative morbidity, and/or recurrence [4]. The dissatisfaction from the curettage procedure resulted from recorded bleeding, inadequate removal, and eustachian tube and/or nasopharyngeal stenosis, which led to the development of technologies to improve the surgical methods of adenoid removal for reaching the most effective techniques [5].
