Endoscopic Submucosal Resection Versus Endoscopic Submucosal Diathermy for Inferior Turbinate Hypertrophy

Endoscopic submucous resection and endoscopic submucous diathermy of the inferior turbinate are two different surgical methods of reducing size in turbinate hypertrophy. We aimed to compare the efficacy of both methods in reducing the nasal symptoms and improving nasal airway. This is a prospective randomized controlled trial conducted in a tertiary hospital, involving fifty patients with inferior turbinate hypertrophy not relieved by medications. After preoperative airway grading using a subjective symptom score, objective airway score and endoscopic score, patients were randomized to undergo either endoscopic submucous diathermy or endoscopic submucous resection. The primary outcome was postoperative improvement of airway and reduction of nasal symptoms. Secondary outcomes were postoperative bleeding and pain. All 24 patients who underwent endoscopic submucous diathermy and 26 who underwent endoscopic submucous resection showed statistically significant reduction in nasal symptoms both in the immediate and late postoperative periods. Patients who underwent endoscopic submucous resection showed greater improvement of airway at 1 week than those who had endoscopic submucous diathermy (p = 0.001). This difference however equalized at the 3-6 months postoperative period. Postoperative bleeding (p = 0.02) and pain (p = 0.04) were significantly more in patients who underwent endoscopic submucous resection. Both endoscopic submucous diathermy and endoscopic submucous resection are equally effective in improving airway in inferior turbinate hypertrophy with a slight advantage of endoscopic submucous resection in the early postoperative period. Reduced postoperative bleeding and pain may make endoscopic submucous diathermy a more attractive option overall.
