| Primary |
Nasal Polyp Score (NPS) |
Each nostril will be assessed separately. The highest score will be graded. Each nostril will be scored from 0-4 (0=no polyps, 1=polyps confined to the middle meatus, 3=polyps extending beyond middle meatus, 4=large polyps causing almost complete nasal obstruction) |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
Lund-Kennedy-Score (LKS) |
Lund-Kennedy-Scores range from 0-12. Scoring includes the assessment of polyps (0=no polyps, 1=middle meatus, 2= beyond middle meatus), discharge (0=no discharge, 1=thin discharge, 2=edema/scarring/crusting (0=absent, 1=mild, 2=severe) |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
Smell Scores |
Sniffing Sticks Screening-16 test ("forced choice"), graded from 0-16 with a higher score indicating a better sense of smell, anosmia is defined as a score =7 |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
Recurrence rates |
Increase of NPS per side = 2 within 2 year follow-up |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
Sinonasal Symptom Score |
nasal congestion, anterior rhinorrhea, posterior rhinorrhea, sneezing, pruritus in the nose, tearing, ear pressure, throat pain, facial pain or pressure, headache, numbness in cheek/lips/teeth. All graded from 0-3 (0=no problems, 1=mild problems, 2= moderate problems, 3= severe problems) |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
Mucus and serum biomarker levels |
Pappalysin-1, Cystatin-SN, Periostin, SerpinE1, SerpinF2 (measured in pg/ml) |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
RSDI (Rhinosinusitis Disability Index) |
validated 30-item Likert scale instrument containing three subscales that assess the impact of sinusitis on physical, functional, and emotional domains. The Score ranges from 0-120. Higher total and subscale RSDI scores represent a worse impact of sinus disease. |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
|
| Secondary |
SF-36 (Short Form-36) |
There is no single overall score for the SF-36, instead, it generates 8 subscales and two summary scores. The subscales are: physical functioning, role limitations due to physical problems, bodily pain, general health perception, vitality, social functioning, role-limitations due to emotional problems, mental health. The scoring ranges from 0-100. Higher total and subscale scores represent a better health situation. |
first visit until 24 months, change is measured between baseline and each follow-up time point up to 24 months (follow-up time points are as follows: 3 weeks, 3 months, 6 months, 9 months, 12 months, 18 months) |
