Septal deviation and chronic sinus disease.
The introduction of computerized tomography in the identification of sinonasal pathology and associated anatomic variants has contributed to a greater understanding of the factors leading to ostiomeatal complex (OMC) obstruction and chronic sinus disease. The OMC and paranasal sinus regions were prospectively evaluated in 150 consecutive patients as a function of the degree of nasal septal deviation and compared with matched controls. These data were correlated with paranasal sinus disease, lateral nasal wall findings, and middle turbinate abnormalities. An increased incidence and severity of bilateral chronic sinus disease was present with increasing septal deviations (p < 0.05). Similarly, patients with increasing nasal septum deviations were noted to have a higher incidence of OMC obstruction (p < 0.05). Ostiomeatal complex obstruction in the direction of septal angulation was associated with nasal septal deformity; however, contralateral OMC obstruction was associated with middle turbinate and lateral nasal wall abnormalities (p < 0.05). The evaluation of the degree of septal angulation has helped better understand the factors contributing to chronic sinus disease and OMC obstruction.
