Background: There is no consensus on the role of surgery in the treatment of chronic rhinitis (CR). Should it be considered when nasal symptoms are not controlled by medical treatment? Various targets (turbinates and secretory nerves) and techniques (surgical, laser, cryotherapy, radiofrequency and phototherapy) have been reported, but benefit varies between reports. The aim of this systematic review and meta-analysis was to evaluate results of surgical and instrumental procedures in CR care., Methods: Two systematic reviews of the US National Library of Medicine, Cochrane Library, Web of Science and Embase databases were conducted in October 15, 2021 (registration numbers CRD42021284257 and CRD42021295227). A database watch was performed until submission of the manuscript. The review focuses on total nasal symptom score (TNSS) and quality of life (QoL) after treatment. All controlled studies reporting nasal surgery/instrumental procedures in adult patients with CR were included., Results: The database search yielded a total of 5628 articles; after eligibility screening, 2091 patients were included from 21 studies. QoL results favored surgery/instrumental procedures over medical treatment (SMD -1.27; 95% CI [-2.38; -0.16]; I 2 =97%), as did TNSS (SMD -1.40; 95% CI [-2.30; -0.50]; I 2 =98%). The small number of studies and their heterogeneity did not allow meta-regression to be performed., Conclusion: This systematic review supports the use of surgical/instrumental procedures to improve nasal symptom score and QoL of adult patients with CR poorly controlled by medical treatment., (Copyright © 2023 Elsevier Masson SAS.

Introduction: The introduction of biotherapies has significantly changed the management of patients with chronic rhinosinusitis with nasal polyps (CRSwNP). These drugs are generally reserved for severe or recurrent CRSwNP. Thus, the concepts of severity of the disease and treatment response must be mastered by otorhinolaryngologists. However, a clear definition of these concepts in CRSwNP is missing., Methods: This article focuses on definitions of severity and treatment response in CRSwNP by providing an expert consensus among French rhinologists, using a Delphi study., Results: The severity assessment should seek the presence of uncontrolled asthma, olfactory disorders, nasal blockage, impaired quality of life (QOL) and cumulative annual dose of systemic corticosteroids.The treatment response should assess the presence of olfactory disorders, nasal blockage, QOL impairment, response to background therapy, resistance and/or dependence to oral corticosteroids, cumulative annual dose of systemic corticosteroids, response to surgery and to biologics.A failure after polypectomy should not be considered as a failure of surgical management of CRSwNP and must discuss the realization of an extended sinus surgery procedure before the prescription of biologics., Conclusion: Definitions of severity, control of CRSwNP, as well as therapeutic strategies to improve patients' QOL achieved high level of consensus.
