State-of-the-art documents like ARIA and european position paper on rhinosinusitis (EPOS) provide clinicians with evidence-based treatment algorithms for allergic rhinitis (AR) and chronic rhinosinusitis (CRS) respectively (1)(2) . The currently available medications can alleviate symptoms associated with AR and RS, and most patients with RS benefit from endoscopic sinus surgery (ESS). In real life, a significant percentage of patients with AR and CRS continue to experience bothersome symptoms despite adequate treatment. This group with so-called severe chronic upper airway disease (SCUAD) represents a therapeutic challenge (3).

Primary Outcome Measures:
  • Control Status of Patients With Rhinosinusitis [ Time Frame: 3 years after FESS ]
    1. Percentage of patients with rhinosinusitis that are fully controlled, partly controlled and uncontrolled according to the new european position paper on rhinosinusitis (EPOS) definitions at a mean interval of 3 years after endoscopic sinus surgery.

Secondary Outcome Measures:
  • Control Nasal Endoscopy [ Time Frame: 3 years after ESS ]
    Evaluating of difference in control if nasal endoscopy is performed three years after ESS.

Other Outcome Measures:
  • Visual Analogue Scale (VAS), Sinonasal Outcome Test (SNOT22) and Short Form (36) Health Survey (SF36) Score Three Years After ESS in Controlled, Partially Controlled and Uncontrolled Group [ Time Frame: three years after ESS ]

    VAS scores: a measurement of patient's subjective evaluation by indicating a position on a line between two endpoints. Patients will score eight individual symptoms on a scale from 0 until 10, being 0 no trouble and 10 maximum trouble. Finally a mean symptom score will be calculated per symptom.

    The SNOT-22 questionnaire is a validated 22 item questionnaire. patients indicate how much they are affected in eight different areas and identify the 5 most important items. The SNOT-22 total score can range from 0 to 110, with higher scores representing worse quality of life.

    Perceived health status can be evaluated by the 36-item short-form (SF-36). It consists of 36 items covering eight domains. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability
