Chronic respiratory rhinitis: Toward endoscopic diagnosis of nasal allergy? An observational study

The study objective was to assess the functional, endoscopic and tomodensitometric semiology of a cohort of patients with chronic respiratory rhinitis (CRR). The concept of CRR is based on the anatomical, pathophysiological and semiological individualization of the respiratory nose within the sinonasal organ, in which three noses are distinguished by the parallel study of evolution and development in the “evo-devo” theory of the origins of the nose, anterior base of the skull and middle third of the face. A single-center retrospective study included a cohort of 28 patients (16 men and 12 women, aged 19 to 69years) with CRR. The main objective was to describe symptoms clinically, endoscopically and on CT. The secondary objective was to compare clinical symptomatology and CT data between CRR and a control group of 31 patients with nasal polyposis (NP). The endoscopic semiology of CRR was analyzed consensually on video recordings using a pre-established grid. The DyNaChron self-administered questionnaire was used to compare symptom intensity and deterioration in quality of life. Olfaction was compared using the Sniffin’ Sticks test. CT opacities were compared between CRR and NP on Lund-Mackay sinus score and a specific ethmoid opacities score. In CRR, endoscopy found a constant association of inflammatory or edematous signs in the inferior or middle turbinates with signs of hypersecretion. Ethmoid opacities in CRR were discrete and significantly smaller than in NP (P
