Anti-IL-5 Therapy With Simple Polypectomy Versus Extended Endoscopic Sinus Surgery for CRSwNP

Change in SNOT-22 Score

The 22-item Sinonasal Outcome Test (SNOT-22) is a questionnaire comprising 22 questions on health-related quality of life in rhinosinusitis. For each item, patients provide a subjective rating on a scale from 0 to 5, where 0 represents "No problem" and 5 represents "Problem as bad as it can be." The total score is the sum of all items and ranges from a minimum of 0 to a maximum of 110. A higher total score indicates a worse outcome, reflecting a poorer quality of life due to rhinosinusitis.

Time frame: Baseline, 2 Weeks after first treatment(operation or biologic treatment) ,at 1,2,3,4,5,6,24,36 month after biological treatment initiation

Change in Nasal Congestion Score

The Nasal Congestion Score (NCS) is a patient-reported outcome measure that assesses the subjective severity of nasal congestion. The score ranges from a minimum of 0 to a maximum of 3, where 0 represents "No nasal congestion" and 3 represents "The most severe nasal congestion." A higher score indicates a worse outcome.

Change in Nasal Polyp Score (NPS)

The Nasal Polyp Score (NPS) is an objective assessment tool, evaluated by a clinician, used to grade the size of nasal polyps. Each nasal cavity is scored separately on a scale from 0 to 4. The total score is the sum of the scores from both nostrils and ranges from a minimum of 0 to a maximum of 8. A higher score indicates larger nasal polyps and a worse outcome. The scoring criteria are as follows: 0: No polyps. 1. Small polyps in the middle meatus. 2. Polyps in the middle meatus reaching below the inferior border of the middle turbinate. 3. Large polyps reaching beyond the inferior border of the middle turbinate or with medial extension from the middle turbinate. 4. Polyps completely obstructing the nasal cavity.

Change in Modified Lund-Kennedy Score

The modified Lund-Kennedy (MLK) score is an objective endoscopic evaluation performed by a clinician. A higher score indicates a worse outcome. It scores nasal polyps, edema, and discharge (0-2 for each) per nostril. The total score ranges from 0 to 12, with a higher score indicating worse endoscopic status.

Change in Blood Eosinophil percentage

Time frame: Baseline, 2 Weeks after first treatment(operation or biologic treatment) ,at 1,2,3,4,5,6,12,24,36 month after biological treatment initiation

Change in Lund-Mackay CT Score

The Lund-Mackay CT scoring system is an objective radiological assessment. It evaluates the extent of opacification on sinus computed tomography (CT) scans in six anatomical regions per side: anterior ethmoid sinuses, posterior ethmoid sinuses, maxillary sinuses, sphenoid sinuses, frontal sinuses, and the ostiomeatal complex. Each region is scored from 0 (no abnormality) to 2 (complete opacification). The total score, which is the sum of scores from all regions across both sides, ranges from a minimum of 0 to a maximum of 24. A higher total score indicates greater disease severity.

Time frame: Baseline, at 6,12, 24,36 month after biological treatment

Change in Olfactory Function

We will provide patients with an olfactory questionnaire, asking them to respond to the following questions. Each question will have a corresponding score: 0 points for "strongly disagree," 1 point for "partially agree," 2 points for "incompletely agree," and 3 points for "strongly agree." The questions include: I feel my sense of smell has become much worse than before. Compared to before the onset of olfactory dysfunction, the taste of food has changed. Sometimes I can smell unpleasant odors that others cannot detect. Some pleasant smells that others enjoy are unpleasant to me. My biggest issue is that, compared to before the onset of olfactory dysfunction, smells are perceived differently. Due to changes in my sense of smell, I dine out less often than before. I worry that I will not be able to adapt to the changes in my sense of smell in the future. Due to changes in my sense of smell, I feel more anxious than before. Changes in my sense of smell often make me feel angry.

Objective Olfactory function Test

Olfactory function was evaluated by the Sniffin' Sticks test, containing olfactory threshold (T), discrimination (D) and identification (I) tests . Score for the threshold test range between 1 and 16, while the scores of the other two tests range between 0 and 16. The results of the three tests were calculated as a total TDI score (range 1- 48), which was used to define functional anosmia (TDI ≤ 16), hyposmia (16 \< TDI \< 31), or normosmia (TDI ≥ 31). If the patients had only been assessed by the identification test, the I score was used to define functional anosmia (I ≤ 8), hyposmia (8 \< I ≤ 11), or 113 normosmia (I \> 11).
