A deviated nasal septum is a condition where the nasal septum is displaced from the center of the nose, causing breathing difficulties and other symptoms.
The nasal septum (Latin: septum nasi) separates the left and right nasal cavities. It extends from the nares anteriorly to the choanae posteriorly and is covered by squamous epithelium.
Concha bullosa (plural: conchae bullosae) (also known as middle turbinate pneumatization) is a common finding and although associated with deviation of the nasal septum, it is usually of little clinical importance.
Nasal bone fractures, when isolated, are most commonly displaced fractures of one of the paired nasal bones. There is often associated with other facial fractures and this requires careful assessment 3,5: nasal septum. orbital blow-out fracture. frontal process of the maxilla.
A nasal septal perforation refers to a defect in the nasal septum resulting in a communication between the two nasal cavities. It may affect either the bony, or cartilaginous septum. Most commonly it affects the anterior septal cartilaginous area although with syphilis it characteristically affects the bony septum.
Intraventricular neoplasms are rare and arise from periventricular structures such as the walls of the ventricular system, the septum pellucidum and the choroid plexus. Many tumor types arise from or can bulge into the ventricular system, although there are certain lesions that are relatively restricted to ventricles.
interventricular septal flattening. commonly referred to as the "D" sign, a reference to the short axis appearance of the left ventricle in the presence of septal flattening. paradoxical septal motion. an abrupt rise in pulmonary arterial pressures prolong right ventricular contraction.
The vomer is one of the unpaired facial bones and forms the posteroinferior part of the bony nasal septum, lying in the midline between the two nasal cavities. It is a thin flat bone that is trapezoidal in shape with two surfaces that are obliquely grooved by the sphenopalatine (nasopalatine) vessels and nerves .

The sphenoid sinuses are paired spaces formed within the body of the sphenoid bone, communicating with the roof of the nasal cavity via the sphenoethmoidal recess in its anterior wall. The two hemisinuses are separated by a septum which may or may not be in the midline. It usually lies anteroinferior to the sella.
