Intervention/exposure

Description of intervention(s) / exposure
Arm 1: patients undergoing FESS and randomly allocated to arm 1, will receive postoperatively intranasal mastic oil solution, subsequently to nasal douching and budesonide nasal spray. Nasal douching will be performed with Neilmed Sinus Rinse twice a day, followed by application of budesonide nasal spray (100 mcg/dose) sprayed in each nostril twice daily (TDD 400 mcg). Subsequently, fifteen minutes later, patients in the lateral head low (LHL or Ragan) position will apply 3 drops of mastic oil 1% solution in each nostril twice a day. Mastic oil solution will be applicable until first postoperative month. Henceforth, patients will continue their therapy with nasal douching and budesonide nasal spray for another month. Face-to-face adherence reminder sessions will take place before discharge from the hospital and at each study visit thereafter. This session will include:
The importance of following study guidelines.
Importance of calling the clinic if experiencing problems possibly related to study product.
Arm 2: Face-to-face adherence reminder sessions will take place before discharge from the hospital and at each study visit thereafter. This session will include:

patients undergoing FESS and randomly allocated to arm 2, will receive postoperatively budesonide by means of nasal nebulization. PARI SINUS (PARI GmbH) nebulizer, that causes the aerosol to pulsate so that it can penetrate the sinus cavities will be provided to patients on arm 2. Patients will apply a Budesonide suspension for inhalation (0.5 mg/2 mL) into the nebulizer upper chamber. Treatment for each nostril will last for 2.5 minutes, twice a day. Treatment shall be completed after two months.
Face-to-face adherence reminder sessions will take place before discharge from the hospital and at each study visit thereafter. This session will include:The importance of following study guidelines.Importance of calling the clinic if experiencing problems possibly related to study product.
Arm 3: patients undergoing FESS and randomly allocated to arm 3, will receive postoperatively oral doxycycline additionally to nasal douching and budesonide nasal spray. Nasal douching will be performed with Neilmed Sinus Rinse twice a day, followed by application of budesonide nasal spray (100 mcg/dose) sprayed in each nostril twice daily (TDD 400 mcg). Additionally, following the first postoperative week, patients will receive doxycycline 200 mg on day 1, followed by 100 mg daily until 56 days post-operatively.
Face-to-face adherence reminder sessions will take place before discharge from the hospital and at each study visit thereafter. This session will include:
The importance of following study guidelines.
Instructions about taking study pills including dose timing, storage, and importance of taking pills whole, and what to do in the event of a missed dose.
Notification that there will be a pill count at every study visit.

Comparator / control treatment
Control group patients will perform nasal douching twice a day using Neilmed Sinus Rinse, apply budesonide nasal spray (100 mcg/dose), sprayed in each nostril twice daily (TDD 400 mcg) and receive a short course of oral cefuroxime (500 mg twice a day for 7 days). Both nasal douching and application of nasal spray will last for two months.

The primary outcome was change in SNOT-22 score 2 months after surgery. Patients were categorized according to baseline SNOT-22 score, and the proportion of patients achieving a SNOT-22 minimal clinically important difference (MCID) of 8.9 was calculated, as well as the percentage change in SNOT-22 score.

Eligibility
Key inclusion criteria
Patients were at least 18 years old, diagnosed with CRS with or without nasal polyposis (EPOS) and scheduled for bilateral functional endonasal endoscopic sinus surgery (FESS) or bilateral revision FESS. Patients with cystic fibrosis, immunodeficiencies, mucociliary dysfunction, fungal balls, systemic vasculitis, granulomatous diseases or cocaine abuse were excluded. The indication for surgery was made when medical treatment as recommended by the EPOS treatment algorithms failed, including saline irrigations, nasal corticosteroids, and one or more courses with oral treatment with oral corticosteroids and/or antibiotics. Nasal corticosteroids were stopped one week before surgery. Systemic corticosteroid drugs were stopped for at least one month before surgery.
Minimum age

Efficacy
Statistical methods / analysis
The sample size was determined based on the mean improvement value of clinical significance of SNOT-22 and endoscopic and imaging staging with Lund-Kennedy and Lund-Mackay systems respectively. For the questionnaire the difference with clinical significance is 8.9 with standard deviation (SD) 2.2 while for Lund – Kennedy and Lund-Mackay it is 2, with (SD) 1.5. Based on the above, in the normogram of Douglas Altman and for study strength at the level of 80% and acceptable type A error: 0.05, acceptable type B error: 0.10, 22 patients are needed for each part of the research.
The analysis will be performed using the statistical package SPSS for Windows, version 23, (Chicago, IL). The data will be expressed as mean ± SD. P values P <0.05 will be considered statistically significant. Parametric tests such as paired t test, two-sample t test, and variance analysis (ANOVA) will be applied to data that follow a normal distribution. Non-parametric tests such as the Mann-Whitney U test, Wilcoxon signed rank test, Sign test, chi-square test and Kruskal-Wallis test will be applied to data that do not follow a normal distribution.
