Avaliação de olfato com uso do teste de connecticut validado em pré e pós-operatório de pacientes com rinossinusite crônica com polipose nasal

Abstract

Introduction: Chronic rhinosinusitis is a clinical, inflammatory syndrome that is highly prevalent in the general population and affects the mucosa of the nasal cavity and paranasal sinuses. Among patients with chronic rhinosinusitis, the presence of smell alteration is estimated in 65-80% of patients. Therefore, it is a common complaint in this group of patients and one of the diagnostic criteria. The CCCRC was recently validated for use in the Brazilian population and there are still no data on the use of this test in this population. Objectives: To study the variation of smell in patients with nasosinusal polyposis in the pre and postoperative period of sinusotomy using the CCCRC validated for Brazil. Define if there is a correlation between the alteration of smell in the postoperative and preoperative moments with the categorization of nasal polyposis and the patients' profile using the following instruments: visual analogue scale, SNOT-22, three-dimensional staging of polyps and tomographic staging. Material and methodology: This is an observational study, with a self-paired series, in patients with chronic rhinosinusitis with nasal polyposis. Smell measurements were performed using the CCCRC and four other variables: visual analogue scale, SNOT-22, three-dimensional staging and tomographic staging, for comparison at two moments, time zero: preoperatively and time one: 60 days after surgery. Results: In general, there was not a good correlation with the measure of smell through the EVA test. The CCCRC has a significant and negative correlation with the SNOT-22 preoperatively. Tomographic staging generally presents a significant and negative correlation with the smell test, in the preoperative period. As for three-dimensional staging, a correlation was identified only when related to vertical staging. Conclusion: The measurement of smell through psychophysical tests is recommended for patients with nasosinusal complaints, especially for patients with established nasosinusal diseases, such as chronic rhinosinusitis with nasal polyposis. The smell measurement should be performed before and after the patient's treatment to document and serially evaluate the smell alteration.
