Anatomical variation of the nasal septum: Correlation among septal components.
Summary of "Anatomical variation of the nasal septum: Correlation among septal components."
The nasal septum consists of multiple components with various developmental origins and is considered a mosaic structure. Few studies have focused on anatomical relationships among the components of the nasal septum, even though they are essential for clinical assessments of morphological abnormalities in the nasal septum. This study was performed to evaluate anatomical correlations among components of the nasal septum using computed tomography (CT) of the paranasal sinus. We studied images from CT scans of 168 paranasal sinuses collected at a secondary referral hospital between July 2008 and February 2009. The area of each component of the nasal septum was measured using median sagittal images of CT scans after three-dimensional reconstruction using computer software. The area of the cartilaginous septum decreased with age, whereas the area of the total nasal septum remained constant. The area of the perpendicular plate of ethmoid increased with age at the expense of the area of the septal cartilage. Clin. Anat., 2010. © 2010 Wiley-Liss, Inc.

Medical and Biotech [MESH] Definitions
The partition separating the two NASAL CAVITIES in the midplane. It is formed by the SEPTAL NASAL CARTILAGE, parts of skull bones (ETHMOID BONE; VOMER), and membranous parts.
Gray matter structures of the telencephalon and limbic system in the brain, but containing widely varying definitions among authors. Included here is the cortical septal area, subcortical SEPTAL NUCLEI, and the SEPTUM PELLUCIDUM. Many authorities consider the septal region to be made up of the septal area and the septal nuclei, but excluding the septum pellucidum. (Anthoney, Neuroanatomy and the Neurologic Exam, 1994, pp485-489; NeuroNames, http://rprcsgi.rprc.washington.edu/neuronames/index.html (November 18, 1998)).
Diagnostic measurement of the nose and its cavity through acoustic reflections. Used to measure nasal anatomical landmarks, nasal septal deviation, and nasal airway changes in response to allergen provocation tests (NASAL PROVOCATION TESTS).
The proximal portion of the respiratory passages on either side of the NASAL SEPTUM. Nasal cavities, extending from the nares to the NASOPHARYNX, are lined with ciliated NASAL MUCOSA.
Abnormalities in any part of the HEART SEPTUM resulting in abnormal communication between the left and the right chambers of the heart. The abnormal blood flow inside the heart may be caused by defects in the ATRIAL SEPTUM, the VENTRICULAR SEPTUM, or both.
