Effect of Chinese Herbal Medicine Nasal Irrigation on the Postoperative Care of Chronic Rhinosinusitis (Breeze Clear)

January 5, 2026 updated by: Rong-San Jiang, Taichung Veterans General Hospital
Investigators tried to evaluate the efficacy and safety of Chinese herbal medicine nasal irrigation as an adjuvant therapy after FESS.

Study Overview

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Chinese herbal medicine
In the Chinese herbal medicine group, Chinese herbal medicine nasal irrigant was first prepared by mixing a pack of 2 gram of SHIN YI CHING FEY TANG, 0.5 gram of chrysanthemum, and 0.125 gram of Borneo camphor powder with 240mL of sterile water in the container of the irrigator. Nasal irrigation was performed by using a NeilMed® SINUS RINSE™ Squeeze Bottle (NeilMed Pharmaceuticals, Inc., Santa Rosa, CA ). When irrigating the nose, patients irrigated both of their nasal cavities each with 120 mL of solutions twice a day. Patients performed nasal irrigations for 2 months.
The bilateral nasal cavity was irrigated by using a NeilMed® SINUS RINSE™ Squeeze Bottle containing 240ml of Chinese herbal medicine solution twice a day for 2 months.
Other Names:
  • 2 gram of SHIN YI CHING FEY TANG, 0.5 gram of chrysanthemum, and 0.125 gram of Borneo camphor
Placebo Comparator: Saline
In the saline group, the normal saline solution was prepared by mixing 1 pack of 2.16 gram salt powder with 240mL of sterile water in the container of the irrigator. Nasal irrigation was performed by using a NeilMed® SINUS RINSE™ Squeeze Bottle (NeilMed Pharmaceuticals, Inc., Santa Rosa, CA ). When irrigating the nose, patients irrigated both of their nasal cavities each with 120 mL of solutions twice a day. Patients performed nasal irrigations for 2 months.
The bilateral nasal cavity was irrigated by using a NeilMed® SINUS RINSE™ Squeeze Bottle containing 240ml of of normal saline twice a day for 2 months.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Taiwanese version of the 22-item Sino-Nasal Outcome Test
Time Frame: From before operation to 3 months after surgery
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.
From before operation to 3 months after surgery
Self-reported adverse events
Time Frame: From before nasal irrigation to after 2-month nasal irrigation
Any adverse events occurring during the 2 months period of nasal irrigation
From before nasal irrigation to after 2-month nasal irrigation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of the second minimal cross-sectional area of the nasal cavity
Time Frame: From before operation to 3 months after surgery
The second minimal cross-sectional area of the nasal cavity was measured by acoustic rhinometry.
From before operation to 3 months after surgery
Change of endoscopic score
Time Frame: From before operation to 3 months after surgery
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.
From before operation to 3 months after surgery
Change of saccharine transit time
Time Frame: From before operation to 3 months after surgery
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.
From before operation to 3 months after surgery
