Abstract

Background& aim: Many previous studies proved that nasal septal deviation has an important effect on the development of the bones of the nose, as well as morphology and other features of facial bones. Assessment of the morphology of the nose helps in obtaining favorable surgical outcomes. We designed this work to discover the association between nasal morphology and nasal septum deviation.
Patients & methods: This study included 120 patients over 18 years old with symptomatic nasal septum deviation who were exposed to CT scanning of the nose and paranasal sinuses. The following parameters were assessed; direction of nasal deviation and its angle in addition to nasal morphology; internasal angle of the nose, the nasal bone length, and the thickness of intermediate and lateral nasal bone on the two sides.
Results: Studied patients’ mean age was 38.08 ± 17.27 years and the majority (70%) of them were males. Out of studied patients, 64 (53.3%) patients had deviated septum toward the right side while in 56 (46.7%) patients it deviated to the left side. It was observed that there were no important differences between types of deviation direction as regarding age, sex, and deviation angle (P= 0.41, 0.09, and 0.61, respectively). Both sexes had insignificant differences as regarding nasal morphology with exception of significantly higher internasal angle (60.33 ± 8.15 vs. 56.19 ± 9.52 degree; P= 0.02), and left intermediate osteotomy thickness (1.92 ± 0.35 vs. 1.77 ± 0.41mm; P= 0.04) in males’ patients. Severe deviation was presented in 19 (15.8%) patients.
Conclusion: This work concludes that deviation of the septum of the nose might influence the morphology of the nasal bones as the length of nasal bone; thickness and lateral osteotomy thickness on the same side of the deviation were altogether more prominent than on the contralateral.
