About this study

Investigators tried to evaluate the efficacy and safety of Chinese herbal medicine nasal irrigation as an adjuvant therapy after FESS.

Read the 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.

Being tested
Chinese herbal medicine Powder, Salt Powder

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Chinese herbal medicine PowderDrug

    Also called 2 gram of SHIN YI CHING FEY TANG, 0.5 gram of chrysanthemum, and 0.125 gram of Borneo camphor

    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.

  • Salt PowderDrug

    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.

Study groupRoleWhat they receive
Chinese herbal medicineExperimentalIn 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.
Receives: Drug: Chinese herbal medicine Powder
SalinePlacebo comparatorIn 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.
Receives: Drug: Salt Powder

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Taiwanese 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.

    Measured: From before operation to 3 months after surgery

  2. Self-reported adverse events

    Any adverse events occurring during the 2 months period of nasal irrigation

    Measured: From before nasal irrigation to after 2-month nasal irrigation

Secondary outcomes (3)
  1. 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.

    Measured: From before operation to 3 months after surgery

  2. 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.

    Measured: From before operation to 3 months after surgery

  3. 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.

    Measured: From before operation to 3 months after surgery

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rong-San Jiang, MD, PhD (886-4-23592525 ext. 82620, rsjiang@vghtc.gov.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Taiwanese version of the 22-item Sino-Nasal Outcome Test (time frame: From before operation to 3 months after surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2026.
