Investigators tried to evaluate the efficacy and safety of Chinese herbal medicine nasal irrigation as an adjuvant therapy after FESS.
In this study, patients with chronic rhinosinusitis who received FESS were recruited and randomly assigned to 2 groups at one month post-surgery. Patients in the xylitol group received 240ml of Chinese herbal medicine nasal irrigation daily for 2 months, and those in the normal saline (NS) group received 240ml of NS nasal irrigation daily for 2 months. Before FESS as well as before and after nasal irrigation, sino-nasal symptoms were assessed by a 22-item Sino-Nasal Outcome Test questionnaire and patients received endoscopic examination, nasal function tests, cytokine measurement of nasal irrigant, and bacterial culture from the middle meatus. The safety of nasal irrigation was assessed by self-reported adverse events, and blood test. This study tried to evaluate the efficacy and safety of Chinese herbal medicine nasal irrigation as an adjuvant therapy after FESS.

RECRUITINGTaiwanese version of the 22-item Sino-Nasal Outcome Test
The Taiwanese version of the 22-item Sino-Nasal Outcome Test contains 22 items of symptoms and social/emotional consequences from nasal disorder. Patients are asked to rate their problems based on how they have been over the past two weeks. Each item is graded from 0 (no problem) to 5 (as bad as it can be) according to its severity and frequency.
Time frame: From before operation to 3 months after surgery
Self-reported adverse events
Any adverse events occurring during the 2 months period of nasal irrigation
Time frame: From before nasal irrigation to after 2-month nasal irrigation
Change of the second minimal cross-sectional area of the nasal cavity
The second minimal cross-sectional area of the nasal cavity was measured by acoustic rhinometry.
Time frame: From before operation to 3 months after surgery
Change of endoscopic score
The endoscopic appearances were categorized into polyps (0: no polyps; 1: polyps present within the middle meatus; 2: polyps beyond the middle meatus); nasal secretion (0: no secretion; 1: clear, thin secretion; 2: thick, purulent secretion); mucosal edema; scarring; crusting; (0: absent; 1: mild; 2: severe). The score ranged from 0 to 20 for both nostrils together.
Time frame: From before operation to 3 months after surgery
Change of saccharine transit time
The saccharine transit test involved placing saccharine granules under the head of the inferior turbinate in the more severely affected nostril. The time interval (minute) between placement of saccharine granules and sensation of sweetness in the throat was recorded.
Time frame: From before operation to 3 months after surgery
