“…Recently, Wong et al studied the correlation between the sizes of NSB and IT. 17 This study revealed a statistically significant correlation between the change in the width of NSB and the total width of IT, while the height of NSB did not show a statistically significant association with that of IT. 17 Several researchers have investigated both age and gender differences related to the size of the structure.…”

Objectives: The nasal septal swell body (NSB), also known as the nasal septal turbinate, is located in the anterior part of the nasal septum. This study is a narrative review of the existing knowledge on recent developments in NSB. Methods: A literature search was performed using PubMed, Embase, Web of Science, Ovid, and Cochrane Library databases. Google Scholar was used to access more extensive literature. The inclusion criteria were human studies published in English. The exclusion criteria were non-English language and animal studies. Results: Of the 345 articles that were initially obtained from 5 databases and Google Scholar, 28 were included in this review. There have been many names for NSBs in the past, which still have no unified terminology recognized by professionals. Pathological investigations revealed that NSB contains a certain amount of sinusoidal blood components. Nasal septal swell body is closely related to the internal nasal valve. Imaging studies have found that the size of NSB is associated with nasal diseases, and NSB hypertrophy can cause anatomic obstruction. In recent years, several procedures for NSB have been reported, and preliminary effectiveness has been achieved. However, the long-term outcomes of volume reduction techniques remain unproven. Conclusions: The NSB is a distinct anatomic structure that may contribute to nasal obstruction and may be reduced surgically with unclear long-term results. Although being investigated for over a century, the unique physiological roles of NSB are not yet fully understood. More evidence is needed to elucidate its physiological effects.

“…Overlooking the contribution of the SSB to NAO may leave the patients with residual nasal obstruction issues even after other contributors have been addressed. SSB hypertrophy has also been correlated with IT hypertrophy and data have shown that treating SSB and turbinate hypertrophy together versus turbinoplasty alone can result in greater cross‐sectional area, nasal volume, and improved NAO symptoms 10,31 10 .…”

“…SSB hypertrophy has also been correlated with IT hypertrophy and data have shown that treating SSB and turbinate hypertrophy together versus turbinoplasty alone can result in greater cross-sectional area, nasal volume, and improved NAO symptoms. 10,31 Like the IT, compensatory SSB hypertrophy can occur (either on the ipsilateral or contralateral side) in the presence of a septal deviation and studies have shown that the SSB thickness can be highly correlated with the degree of the septal deviation. 10 Notably, a third of patients (23/70) in this study had undergone a prior nasal procedure with turbinate reduction/excision (n = 13) or septoplasty (n = 11) done alone or in combination with other procedures.…”

BackgroundNasal airway obstruction (NAO) is a highly prevalent disorder. Septal swell body (SSB) hypertrophy is an often overlooked contributor to NAO. SSB treatment may relieve symptoms of NAO. The objective of this study was to assess the clinical use of a temperature‐controlled radiofrequency (TCRF) device to treat SSBs to improve symptoms in adults with NAO.MethodsIn this prospective, multicenter, open‐label, single arm study, patients with severe or extreme NAO related to SSB hypertrophy received bilateral TCRF treatment in the SSB area. The primary endpoint was improvement in Nasal Obstruction Symptom Evaluation (NOSE) Scale scores from baseline to 3 months postprocedure. A subset of study patients underwent computed tomography (CT) imaging to evaluate posttreatment changes in SSB size.ResultsMean NOSE Scale scores significantly improved from 73.5 (SD 14.2) at baseline to 27.9 (SD 17.2) at 3 months postprocedure, a reduction of −45.3 (SD 21.4, 95% confidence interval [CI]: −50.4 to −40.1; p < 0.0001); the responder rate was 95.7% (95% CI: 0.88 to 0.99; p < 0.0001). CT evaluation at 3 months showed statistically significant reductions in the SSB with the greatest reduction in the middle thickness (mean change −3.4 [SD 1.8] mL, 95% CI: −4.0 to −2.8; p < 0.0001). Minimal adverse events with any relationship to the device or procedure were reported; none were serious in nature and no septal perforations occurred.ConclusionsThis study demonstrates that TCRF treatment of SSB hypertrophy is well tolerated and effective at reducing both SSB size and symptoms of NAO at 3 months posttreatment.

BackgroundImproved nasal airway obstruction (NAO) symptoms were reported at 3 months following temperature‐controlled radiofrequency (TCRF) treatment of the septal swell body (SSB). This report provides results from assessments of the long‐term safety and efficacy of TCRF treatment of SSB hypertrophy to treat NAO through 12 months posttreatment.MethodsThis prospective, multicenter, long‐term, open‐label study was conducted in nine centers within the United States and included patients with severe/extreme NAO attributed to SSB hypertrophy. Outcome measures included assessments of Nasal Obstruction Symptom Evaluation Score (NOSE), Numeric Rating Scale (NRS) ease‐of‐breathing, patient satisfaction, and adverse events at 6 and 12 months.ResultsOf the 70 patients treated, 65 and 62 patients completed the 6‐ and 12‐month follow‐up assessments. Compared to baseline, there was a 67.5% decrease in adjusted mean NOSE scores at 6 months (mean change −49.6, 95% confidence interval [CI] −54.8 to −44.4; p < 0.001) and a 65.4% decrease at 12 months (mean change −48.1, 95% CI −53.7 to −42.5); p < 0.001), which is consistent with previously published 3‐month results. A 62.0% and 62.5% improvement compared to baseline was observed in the NRS ease‐of‐breathing score at 6 and 12 months, respectively (p < 0.001). No serious adverse were reported overall and no new device‐ or procedure‐related adverse events were reported in the interval between 3 and 12 months posttreatment.ConclusionTCRF treatment of SSB hypertrophy has a significant and durable effect on improving the symptoms of NAO and health‐related quality of life in patients with symptoms of nasal obstruction and congestion through 12 months postprocedure.
