# Coblation Adenoidectomy Versus Conventional Adenoidectomy: A Comparative Study of two Different Techniques of Adenoidectomy

## TL;DR

This study compares two adenoidectomy techniques and finds that endoscopic coblation leads to better outcomes with less blood loss and pain.

## Contribution

The study provides a direct comparison of coblation and conventional curettage adenoidectomy techniques in pediatric patients.

## Key findings

- Endoscopic coblation achieved complete adenoid removal in 75% of cases versus 15% with conventional methods.
- Coblation reduced blood loss and postoperative pain significantly compared to curettage.
- Recovery time was shorter for patients undergoing endoscopic coblation adenoidectomy.

## Abstract

Chronic nasal obstruction, frequent respiratory infections, recurrent ear blocks, earaches, and pediatric obstructive sleep apnea may indicate adenoid enlargement, one of the most common conditions encountered in pediatric otorhinolaryngology practice. Adenoidectomy is a simple procedure with certain limitations, which has led to various innovations in surgical techniques in the recent past. The study aimed to compare two different adenoidectomy techniques: the endoscopy-assisted coblation adenoidectomy and the conventional curettage adenoidectomy.

In this prospective randomized interventional study involving 40 patients, 20 patients in Group A underwent curettage adenoidectomy, and 20 patients in Group B underwent endoscopic coblation adenoidectomy. Complete adenoid tissue removal, surgical blood loss, operative duration, postoperative pain, and recovery time are the outcome measures.

Endoscopy-assisted coblation adenoidectomy enabled complete adenoid removal better than conventional adenoidectomy, 15 patients (75%) had complete removal versus 3 patients (15%) in the conventional group (p-value of 0.0003). The mean blood loss was 30 ± 5.60 mL in Group A and 10.75 ± 2.93 mL in Group B (p = 0.0001). The pain score assessed using the visual analog scale was 4 ± 0.44 in Group A and 3 ± 0.36 in Group B (p = 0.0001). The mean time taken for recovery in Group A was 3.14 ± 0.62 days and that in Group B was 2.64 ± 0.64 days (p = 0.001).

Coblation adenoidectomy under endoscopic guidance enabled complete adenoid removal, reduction in surgical blood loss and postoperative pain, and shortened recovery time.
