The nasal septal body (NSB) is a widened region of anterior nasal septum which is located superior to the inferior, and anterior to the middle turbinate. It consists of mucosa and a marked soft tissue overlying the cartilage and bone. Both cartilage and mucosa is thicker here compared to the other parts of the nasal septum. NSB plays an important role in the regulation of nasal airflow. Because it contains venous sinusoids, it is also called the septal turbinate. Because it contains venous sinusoids, it is also called as septal turbinate. Despite of its important role in the regulation of nasal airflow, it is often ignored and may be confused with a high nasal septal deviation. In published studies, NSB has been mainly investigated histologically. Although there are a limited number of histological and anatomical studies related to NSB, to our best knowledge there are no study on radiological examination of NSB size in patients with allergic rhinitis. Here, our aim was to determine whether there is any radiologically detected effect of allergic rhinitis on NSB size.

AbstractObjective: To determine whether there is any radiologically detected effect of allergic rhinitis on nasal septal body (NSB) size. Methods:Forty patients previously diagnosed with allergic rhinitis, and randomly selected thirty controls without allergic rhinitis were included in this study. Measurements of NSB size were performed in coronal plane paranasal sinus CT. Patients who had undergone nasal surgery, those with nasal polyposis, patients still using topical nasal spray, oral antihistamines, oral steroids and oral leukotrienes were excluded from the study. Results:The average width of NSB was found 11.2 mm in patients with allergic rhinitis and 10.74 mm in patients without allergic. There was no significant difference between patients with and without allergic rhinitis in terms of NSB size on coronal plane paranasal sinus CT examination. Conclusion:Our results did not support the findings of previous studies. However, further randomized, prospective, controlled trials o...

Nasal obstruction most commonly occurs due to mucosal abnormalities and those in cartilage-bone structure such as nasal polyp, septum deviation, concha hypertrophy and chronic sinusitis in adults. Adenoid vegetation is the most prominent cause in childhood. In the present study, we aimed to investigate whether maxillary and palatal bone developments continue in patients with abnormalities causing nasal obstruction. As computerized tomography is the optimal imaging modality in nasal cavity abnormalities, CT scan findings of patients with Control nasal polyp, chronic sinusitis and septum deviation were retrospectively evaluated; and palatal curve changes were compared. In our study, it was found that maxillary bone curve was widened in adult patients with nasal polyp; this angle was further narrowed in those with chronic sinusitis; and maxillary bone curve narrowing and increase in the distance to palatal bone was smaller in patients with septum deviation than those in chronic sinusitis. In the light of these findings, we concluded that, in adults, maxillary and palatal bone developments continue in certain circumstances including nasal polyp, chronic sinusitis or septum deviation.

“…This explains the greater vasoconstrictive potential of the inferior turbinate, as revealed by MRI and CT scanning (3,9,10). Even though sinusoids are not as abundant in the NSC region, changes in the volume of sinusoids in the nasal valve region including the NSC may lead to nasal obstruction more rapidly and more frequently than in the inferior turbinate.…”

“…The NSB may experience nasal obstruction even following minimal changes in mucosal thickness. Computed tomography (CT) and magnetic resonance imaging (MRI) evaluation of the NSB showed vasoactive expansile properties but not as much as in the inferior turbinate (2,3). Histological evaluation of the NSB revealed the presence of seromucinous glands, venous sinusoids and vascular structures (1).…”
