Outcome Measures

Primary Outcomes (2)

  • 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.

    From before operation to 3 months after surgery

  • Self-reported adverse events

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

    From before nasal irrigation to after 2-month nasal irrigation

Secondary Outcomes (5)

  • Change of the second minimal cross-sectional area of the nasal cavity

    From before operation to 3 months after surgery

  • Change of endoscopic score

    From before operation to 3 months after surgery

  • Change of saccharine transit time

    From before operation to 3 months after surgery

  • Change of score measured by Eustachian Tube Dysfunction Patient Questionnaire

    From before nasal irrigation to after 2-month nasal irrigation

  • Change of Eustachian Tube function by the nine-step inflation/deflation test

    From before nasal irrigation to after 2-month nasal irrigation

Study Arms (2)

xylitol

EXPERIMENTAL

In the xylitol group, 5% xylitol solutions were first prepared by mixing two packs of 10 mg xylitol powder with 400 mL of sterile water in the container of the irrigator. Nasal irrigation was performed by using a Sanvic SH903 pulsatile irrigator (Yun-Wang Industrial Co., Tainan, Taiwan). When irrigating the nose, patients irrigated both of their nasal cavities each with 200 mL of solutions once a day. Patients performed nasal irrigations for 2 months.

Drug: Xylitol Powder

saline

PLACEBO COMPARATOR

In the saline group, the normal saline solution was prepared by mixing 2 packs of 1.8 mg salt powder with 400 mL of sterile water in the container of the irrigator. Nasal irrigation was performed by using a Sanvic SH903 pulsatile irrigator (Yun-Wang Industrial Co., Tainan, Taiwan). When irrigating the nose, patients irrigated both of their nasal cavities each with 200 mL of solutions once a day. Patients performed nasal irrigations for 2 months.

Drug: Salt Powder

Interventions

The bilateral nasal cavity was irrigated by using a Sanvic SH903 pulsatile irrigator containing 400 ml of xylitol solution once a day for 2 months.
