Double pledget nasal anesthesia
Single pledget nasal anesthesia
All patients in the double pledget nasal anesthesia group receive endoscopic-guided gauze nasal pledgetting to both the inferior nasal meatus and middle nasal meatus. Each patient will receive an anterior rhinoscopy to select the most patent meatus by a validated meatus scoring scale. The endoscope is preloaded with a 1.8 mm biopsy forceps to pick up a right-angled gauze strip. A preloaded biopsy forceps is protruded slowly into the middle meatus first under endoscope monitoring. The second gauze pledgetting procedure is performed two minutes after the first gauze pledgetting which serves to induce turbinate size reduction to both the INT and MNT. A gauze strip is at least brought onto the posterior end of the inferior or middle turbinate.
All patients in the single pledget nasal anesthesia group receive endoscopic-guided gauze nasal pledgetting to either the inferior nasal meatus or middle nasal meatus determined by anterior rhinoscopy. Each patient will receive an anterior rhinoscopy to select the most patent meatus by a validated meatus scoring scale. The endoscope is preloaded with a 1.8 mm biopsy forceps to pick up a right-angled gauze strip. A gauze strip is at least brought onto the posterior end of the inferior or middle turbinate.
