The laboratory in which the analyses on nasosinusal polyposis were to be carried out did not want to continue the research on this subject, so it was decided to stop this study prematurely.

Impaired olfaction is one of the major complaints of patients with nasosinus polyposis, with nasal obstruction. In case of failure of medical treatment for patients with polyposis nasosinusal, they may use endoscopic surgery nasosinusal. Before surgery, 73% are hyposmic or anosmic, compared to 43% after surgery. Persistence of hyposmia or anosmia despite the removal of polyps can be explained by mechanisms inflammatory in the mucous membrane of the olfactory cleft. In addition, studies in mice have shown a degeneration of primary olfactory neurons at the level of the olfactory mucosa in connection with directly with TNF alpha, a pro-inflammatory molecule.

| Sniffin Stick Test | Diagnostic Test | The test consists of odorous rods that are presented to the patient's nose. It consists of 3 parts different, with 3 sets of corresponding sticks: an olfactory threshold test, an olfactory discrimination test and an olfactory identification test. The final score, out of 48, is the sum of the olfactory threshold, discrimination and identification scores. Normal test values are defined as greater than the tenth percentile of the general population, so the test result is compared to reference values on a chart to determine whether the patient is normosmic, hyposmic or anosmic. |
| Measure | Description | Time Frame |
|---|---|---|
| expression rate of TNF-alpha in biopsies | The main evaluation criterion is based on two variables: the expression rate of TNF-alpha in olfactory slit biopsies and the Sniffin Stick test score. | 2 months |
| Sniffin Stick test score | The main evaluation criterion is based on two variables: the expression rate of TNF-alpha in olfactory slit biopsies and the Sniffin Stick test score. Sniffin Stick test score : The final score, out of 48, is the sum of the olfactory threshold (out of 16), discrimination (out of 16) and identification (out of 16) scores. Normal test values are defined as greater than the tenth percentile of the general population, so the test result is compared to reference values on a chart to determine whether the patient is normosmic, hyposmic or anosmic. | 2 months |
