Abstract
Introduction Chronic rhinosinusitis (CRS) is of varied etiology, anatomic and physiological variations may play significant rolesin its aetiopathogenesis. Use of nasal Endoscopes and Computerised Tomographic scanshave improved both the diagnostic and therapeutic management of CRS. Most centres in sub-Saharan Africa rely on less detailedmethods in clinical evaluation without the use of endoscopes and Computerised Tomographic scans which have been proven to be indispensable tools in CRS management. Several studies in many parts of the world have given different results on the role of the nasal anatomical variations in causing CRS; this study will provide an idea on the role of these variations in CRS in this sub region. Objectives: To assess the nasal anatomical variations in adults with CRS using nasal endoscopy and to ascertain if these variations predispose to CRS. Materials and Method: The study was a prospective hospital-based study. Patients with CRS were recruited consecutively from the Ear Nose and Throat (ENT) department and the general outpatient unit of UsmanuDanfodiyo University Teaching Hospital (UDUTH), Sokoto. Controls consisting of individuals without CRS symptoms were matched in a 1:1 ratio. Nasal endoscopy was done for all participants following the standard passes. Data was analysed with SPSS version 20. Results: A total of 132 patients, with an equal number of controls were recruited. Patients age ranged between 18 to 68 (mean of 31.9) years,with male to female ratio of 1.1: 1, with that of controls ranging 18 to 59 (mean of 30.6) years, and a male to female ratio of 1.2:1. Nasal septal deviation/spur was the most common nasal anatomical variation, in 57 (43.2%) patients, followed by concha bullosa, in 24 (18.2%) patients, large bulla ethmoidalis, in 23 (17.4%) patients, and paradoxically curved middle turbinate, in 14 (10.6%) patients. CRS was significantly associated with nasal septal deviation (P=0.01), concha bullosa(P=0.001), and paradoxically curved middle concha (P=0.001). There was no significant association between CRS and large bulla ethmoidalis air cells (P= 1.0). Conclusion: In this study, 43.2% of the study population had nasal septal deviation, 18.2% had concha bullosa, and 10.6% had paradoxically curved middle turbinate which predispose to CRS.
