Brief Summary:
nasosinus polyposis (=PNS) is a chronic inflammatory disease of the nasal cavity and sinus cavity with a prevalence of 2 to 4% in the general population. The functional impact of PNS has a major impact on one's quality of life.Medical treatment, nasal irrigations and local glucocorticoids as well as short treatment of oral glucocorticoids have shown a short-term benefit versus placebo. Surgery improves the efficacy of local treatments, but 40% of patients have a recurrence of polyps at 18 months and 20% of patients require a surgery recovery at 5 years. The development of monoclonal antibodies directly targeting the inflammatory way is a real public health issue. Bachert C. et al recently demonstrated the efficacy of Dupilumab (anti-IL-4/13 antibody) injected subcutaneously on the overall symptomatology of PNS. The marketing authorization (AMM) for the first biotherapy to be available soon includes PNS's severe nature and resistance to treatment, although there is no consensus definition or score to characterize this severity. This study aims at developping a score for assessing severity in PNS. We suggest that this assessment strategy could be applied to the PNS. The originality and the innovative character of this project is the statistical modeling behind the creation of the score. Thus, the importance of symptoms, anatomical and biological factors, the estimation of the quality of life of the patients, the level of care use and the number of surgeries all become measurable indicators that are a direct reflexion of the severity and the control of PNS, called latent variables because they cannot be directly measured. To consider this detail, modeling using structural equations seems optimal to develop a severity score (PSI score) of PNS in order to personalize the therapeutic care of patients. Main Objective: To develop a severity score for PNS using latent variable modeling: Polyps Severity Index (PSI)

Condition or disease Intervention/treatment
Nasal Polyposis Other: Questionaries

Detailed Description:

In practice, during their otolaryngologist (ORL) consultation, patients will have a complete clinical check-up and will be prescribed the necessary complementary examinations if they have not already been performed recently (<6 months). All data will be collected in an anonymous database.

The patient will answer a questionnaire to evaluate the cardinal symptoms of PNS using a visual scale from 0 to 10. He will then have a standard ORL clinical check-up (otoscopy, then rhinoscopy with speculum and nasal endoscopy) in order to make a nasal anatomical assessment (duration 5 minutes).

They will be given a questionnaire on admission to the waiting room to find out the impact of their nasal discomfort on their quality of life (score used routinely and validated in the literature, SNOT-22), as well as a questionnaire concerning their asthma if it exists (score used routinely and validated in the literature, ACT). The importance of the endoscopic involvement will be evaluated using the Lidholt score (see Appendix) and the importance of the radiological involvement directly from the CT or Cone beam computed tomography (=CBCT) results using the Lund-MacKay score. The estimated time to complete these questionnaires and to assess the endoscopic and radiological involvement is an additional 10 minutes. Blood will be drawn (as part of the initial routine workup) to assess complete blood count (for blood hypereosinophilia) and IgE levels (serum and total IgE). We will repeat the assessment routinely performed as part of the follow-up of patients with PNS by questionnaire, interview and physical check-up at 3 months when the patients return for their follow-up visit. No additional exams or questionnaires to the routine workup will be performed for this study.
