Objectives:
We intended to investigate the deviation of septal swell body, perpendicular plate, septal spur and vomer in patients with and without nasal obstruction.
Methods:
We compared the deviation of these septal areas in computed tomography scans of patients scheduled for nasal surgical procedures (cases) and of patients without clinically relevant nasal obstruction (controls).
Results:
Septal swell body was similarly deviated between 56 cases (median value: 6.5 mm) and 56 controls (6.4 mm; p > 0.2). Septal spur was more deviated in cases (5.6 mm) than in controls (4.7 mm; p < 0.001). The deviation of perpendicular plate (found in 28/112 subjects) did not differ significantly between cases (3.0 mm) and controls (2.2 mm; p > 0.2). The deviation of vomer (found in 71/112 subjects) was larger in cases (7.1 mm) than in controls (4.3 mm; p = 0.001).
Conclusion:
Septal spur, vomer and perpendicular plate were more frequent causes of nasal obstruction compared to septal swell body.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
