The nasal swell body (NSB) is considered to be an enlarged region of the nasal septum, which is located superiorly to the inferior nasal turbinate and anteriorly to the middle nasal turbinate, with a potential effect upon the airflow nasal valve. The histological studies of the NSB demonstrated that it is a glandular formation, not a venous structure, and it is formed by septal cartilage and bone, as well as a thick mucosa. Recent studies emphasized the functional role of the nasal swell body and it is thought to interfere with the nasal airflow and air humidification, due to its proximity to the internal nasal valve and its histological characteristics (venous sinusoids and seromucinous glands). The nasal swell body is strongly related to the presence of rhinosinusal chronic inflammations (allergic rhinitis and chronic rhinosinusitis) and the septal deviation. In case of the presence of the nasal swell body, surgical treatment is not commonly done, due to the absence of a consensus between the ENT practitioners. Most of them consider surgery as being too aggressive because of the presence of seromucinous glands, with slight impact upon the nasal obstruction. Most probably, the lack of consensus is determined by inconsistent anatomical and histological study results.

Correlation between septal body size and inferior turbinate hypertrophy on computerised tomography scans in fifty patients: A radiological analysisThe septal body (SB), also known as the nasal swell body or septal turbinate, is a distinct anatomical structure located superior to the inferior turbinate (IT) and anterior to the middle turbinate. It is composed of mucosa and soft tissue overlying cartilage and bone, and it has a thicker mucosal covering than the other portions of the nasal septum. [1][2][3][4][5] The location and structural characteristics of the SB imply that it impacts and regulates nasal airflow. 3,5-7 Indeed, the SB's impact on nasal physiology may be similar to that of the IT. From a histological perspective, the high proportion of venous sinusoids within the SB suggests that it can alter nasal airflow in a similar way to the IT. 1,3 Furthermore, one recent study revealed that, in patients with a septal deviation, the SB is more prominent contralateral to the deviation. This is similar to the compensatory IT hypertrophy that is also seen in such patients. 2 In this regard, Yu et al suggested that a hypertrophied SB can be reduced in volume using a microdebrider to treat nasal obstruction, 8 indicating that SB hypertrophy combined with IT hypertrophy reduces nasal cross-sectional area and increases resistance to airflow.Given the histological and structural similarities between SB and IT, we hypothesised that SB hypertrophy accompanies IT hypertrophy in a high proportion of patients. To our knowledge, no previous studies have addressed the correlation between SB size and IT hypertrophy. Therefore, the aim of this study was to determine, using computerised tomography (CT) scanning, whether SB size correlates with IT hypertrophy. | METHODS | Ethical considerationsThis study was approved by the Institutional Review Board of Konkuk University Chungju Hospital. | SubjectsWe analysed CT scans of the paranasal sinus (PNS) in 50 consecutive patients who presented to the Otolaryngology Department of Konkuk University Chungju Hospital between January 2015 and December 2016 complaining of headache, intermittent nasal obstruction, maxillofacial trauma, or loss of smelling. All patients were at least 16 years old. This study excluded CT scans of the PNS in patients with definite septal deviation, asymmetric IT hypertrophy, definite septal bone hypertrophy, acute or chronic rhinosinusitis, nasal polyps, maxillofacial fractures, and/or evidence of previous surgery.

Bu çalışmada alerjik rinit (AR) ve diğer sinonazal patolojileri olan ve olmayan hastalarda nazal septal cisim genişliğinin (NSC) araştırılması ve karşılaştırılması amaçlandı. Hastalar ve Yöntemler: Çalışmaya toplam 577 birey dahil edildi. Çalışma grupları, çeşitli sinonazal patolojileri ve/veya AR'si olan 488 erişkin hastadan, kontrol grubu ise paranazal radyografik bulguları ve alerji testleri tamamen normal olan 89 sağlıklı bireyden oluşuyordu. Çalışma grubundaki hastalar kendi içinde dört gruba ayrılarak incelendi; grup 1 sadece sinonazal patolojisi olan hastalar (septum deviyasyonu, akut sinüzit, kronik sinüzit ve/veya nazal polipozis), grup 2 hem sinonazal patolojileri hem de AR'si olan hastalar, grup 3 sadece AR tanılı hastalardan oluşturuldu, grup 4 ise kontrol grubu olarak tasarlandı. Bulgular: Grup 1'de 201 (%34.8) hasta, grup 2'de 211 (%36.6) hasta, grup 3'de 76 (%13.2) hasta ve grup 4'de ise 89 sağlıklı birey (%15.4) mevcuttu. Bunlardan 299'u (%51.8) kadın, 278'i (%48.2) erkekti. NSC erkeklerde kadınlardan anlamlı olarak daha büyüktü. Ortalama NSC genişliği 1.2±0.2 idi. NSC boyutları her üç çalışma grubunda da kontrollere kıyasla anlamlı olarak daha büyüktü (p<0.001). Sonuç: Çalışmamız, literatür ile uyumlu olarak NSC'nin AR ve sinus patolojilerinde benzer oranlarda büyüdüğünü desteklemektedir. Burun tıkanıklığı ile başvuran hastalarda, fizik muayeneye ek olarak paranazal sinüs tomografisi ile değerlendirme etkin tanı ve tedavi için büyük öneme sahiptir.
