Análisis de las variantes anatómicas rinosinusales encontradas en pacientes con rinosinusitis crónica sometidos a cirugía funcional de nariz y senos paranasales

Abstract

Introduction: Chronic rhinosinusitis is a high global prevalence disease which initial treatment is medical management based on steroids and nasal irrigations; many patients do not achieve adequate control, so they are candidates to functional endoscopic surgery. Many rhinosinusal anatomical variants have been identified, which could predispose failure of medical management. Objective: To identify the anatomical variants in patients with chronic rhinosinusitis undergoing functional endoscopic surgery of the nose and paranasal sinuses in a tertiary care hospital. Material and methods: A retrospective, cross-sectional, descriptive and observational study was carried out. Clinical records of patients diagnosed with chronic rhinosinusitis undergoing functional endoscopic surgery in the period from January to December 2017 were studied; pre-surgical computed tomography studies were reviewed to identify the anatomical variants present as well as the severity of rhinosinusitis using the Lund-Mackay tomographic classification system. Results: Anatomical variants were found in 85.1% of the patients; the most frequent was septal deviation (76.5%). Conclusion: There is no important relationship between the severity of the disease and the anatomical configuration of the patient.
