Retrospective evaluation of radiofrequency volumetric tissue reduction for hypertrophic turbinates in dogs with brachycephalic obstructive airway syndrome.

OBJECTIVE: The objective of this study was to retrospectively assess the effect of Radiofrequency Volumetric Tissue Reduction (RFVTR) on hypertrophic turbinates and clinical outcome in brachycephalic dogs when included in multi-level surgery (MLS). STUDY DESIGN: Clinical retrospective multicenter study. ANIMALS: 132 client-owned brachycephalic dogs. METHODS: 132 brachycephalic dogs with high-grade Brachycephalic Obstructive Airway Ayndrome (BOAS) and hypertrophic turbinates were treated with RFVTR as part of MLS of the upper airways. Intranasal obstruction was evaluated by computer tomography (CT) and antero-/retrograde rhinoscopy before and 6 months after RFVTR. The clinical records, the CT images and the rhinoscopy videos were reviewed and clinical evolution was evaluated using a standardized questionnaire. The data was scored semi-quantitatively. RESULTS: In this study, 132 patients were included for a follow-up period of 120 weeks. RFVTR resulted in minor complications, including serous nasal discharge within the first postoperative week in all dogs, and intermittent nasal congestion between 3-8 weeks after treatment in 24.3% of the patients. Rhinoscopy and CT follow-ups were available for 33 patients. Six months after treatment intranasal airspace was increased (p = 0.002) and the presence and overall amount of mucosal contact points was reduced (p = 0.039). CONCLUSION: MLS with RFVTR led to a significant reduction in turbinate volume at the 6-month follow-up examination and significant clinical improvement over a long-term period of 120 weeks. This suggests the viability of RFVTR as a turbinate-preserving treatment for intranasal obstruction in dogs with BOAS. CLINICAL SIGNIFICANCE: RFVTR is a minimally invasive turbinoplasty technique for intranasal obstruction in dogs with BOAS and can be included in MLS without increasing complication rates.

[1-11C]-Butanol Positron Emission Tomography reveals an impaired brain to nasal turbinates pathway in aging amyloid positive subjects.

BACKGROUND: Reduced clearance of cerebrospinal fluid (CSF) has been suggested as a pathological feature of Alzheimer's disease (AD). With extensive documentation in non-human mammals and contradictory human neuroimaging data it remains unknown whether the nasal mucosa is a CSF drainage site in humans. Here, we used dynamic PET with [1-11C]-Butanol, a highly permeable radiotracer with no appreciable brain binding, to test the hypothesis that tracer drainage from the nasal pathway reflects CSF drainage from brain. As a test of the hypothesis, we examined whether brain and nasal fluid drainage times were correlated and affected by brain amyloid. METHODS: 24 cognitively normal subjects (≥ 65 years) were dynamically PET imaged for 60 min. using [1-11C]-Butanol. Imaging with either [11C]-PiB or [18F]-FBB identified 8 amyloid PET positive (Aß+) and 16 Aß- subjects. MRI-determined regions of interest (ROI) included: the carotid artery, the lateral orbitofrontal (LOF) brain, the cribriform plate, and an All-turbinate region comprised of the superior, middle, and inferior turbinates. The bilateral temporalis muscle and jugular veins served as control regions. Regional time-activity were used to model tracer influx, egress, and AUC. RESULTS: LOF and All-turbinate 60 min AUC were positively associated, thus suggesting a connection between the brain and the nose. Further, the Aß+ subgroup demonstrated impaired tracer kinetics, marked by reduced tracer influx and slower egress. CONCLUSION: The data show that tracer kinetics for brain and nasal turbinates are related to each other and both reflect the amyloid status of the brain. As such, these data add to evidence that the nasal pathway is a potential CSF drainage site in humans. These data warrant further investigation of brain and nasal contributions to protein clearance in neurodegenerative disease.

Severe Hypoplasia of Paranasal Sinuses and Turbinates.

This case report describes a patient in their 40s with a history of bronchiectasis, azoospermia, and epididymal cysts who presented with bilateral nasal obstruction.

Juvenile trabecular ossifying fibroma of the inferior turbinate.

Nasal obstruction is a commonly reported issue in the Otorhinolaryngology Outpatient Department. In this case, an early adolescent boy with a long-standing problem of right-sided nasal obstruction since childhood sought consultation. Diagnostic nasal endoscopy revealed a deviation of the nasal septum to the left, coupled with right inferior turbinate hypertrophy, all overlying healthy mucosa. A CT scan of the nose and paranasal sinuses further identified a bony hyperdense lesion with ground glass attenuation, confined to the right inferior turbinate. Subsequent biopsy confirmed juvenile trabecular ossifying fibroma (JTOF). The patient underwent endoscopic right medial maxillectomy, and the final histology affirmed the diagnosis of JTOF.

Morphology, Not Only Volume: A Study on Empty Nose Syndrome and Inferior Turbinates.

OBJECTIVES: Empty nose syndrome (ENS) is an underdiagnosed but burdensome clinical condition. Studies that have addressed the impact of remnant inferior turbinate volume (ITV) on ENS are scarce. We aimed to evaluate the impact of ITV and phenotyping on the severity and presentation of ENS. METHODS: All the enrolled patients underwent the following subjective assessments: the ENS 6-Item Questionnaire (ENS6Q), Sino-Nasal Outcome Test-25 (SNOT-25), Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI). The ITV was obtained from finely cut (1-mm-thick slices) sino-nasal computed tomography scan images and analyzed using ImageJ. The correlation between ITV, subjective measurements, and morphology of inferior turbinates was evaluated. ENS was categorized as torpedo type (balanced tissue volume) or pistol type (posterior dominance) based on the morphology. RESULTS: Overall, 54 patients met the inclusion criteria. The ITV was positively correlated with the ENS6Q score and domain of ENS symptoms in SNOT-25. Neither BDI-II nor BAI scores had a significant correlation with ITV. Based on their morphological classification, the torpedo type exhibited diverse manifestations in the SNOT-25 analysis in response to changes in ITV, while the pistol type demonstrated an elevated rhinologic symptom burden and ENS-specific symptoms as their ITV increased. Nasal resistance did not correlate with the ITV in either type of ENS. CONCLUSIONS: Symptoms were paradoxically worse in ENS patients with greater remnant ITV, and distinct morphological phenotypes in the nasal cavities may result in different presentations. Further investigation into the correlation between remnant inferior turbinates and nerve function is warranted. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3060-3066, 2024.

[Intraosseous cavernous hemangioma of the middle turbinate. Clinical cases]. / Vnutrikostnaya kavernoznaya gemangioma srednei nosovoi rakoviny. Klinicheskie sluchai.

Intraosseous vascular pathology of the turbinates is extremely rare in the practice of an otorhinolaryngologist and can be presented in various histopathological variants. The article presents two clinical cases in which an intraosseous cavernous hemangioma was hidden under the mask of a hypertrophied middle turbinate. The final diagnosis was established by the results of histological examination. The analysis of these clinical cases indicates that, despite the low prevalence, atypical clinical and CT picture, intraosseous formations of the nasal cavity can be of a vascular nature and certainly require a comprehensive examination, including CT, CT with contrast and/or MRI of the nose and paranasal sinuses. These clinical observations indicate that preliminary embolization of feeding vessels before surgical treatment is not required.

Effect of turbinate surgery on mucociliary clearance. A systematic review and metanalysis / Efecto de la cirugía turbinal en el aclaramiento mucociliar. Revisión sistemática y metaanálisis

Despite the fact that turbinate surgery provides satisfactory results regarding nasal obstruction, most of these procedures are destructive, to some extent, for the respiratory epithelium. There are valid hypotheses suggesting either that turbinate surgery may improve mucociliary clearance (MCC) by improving rhinitis, as well hypotheses suggesting that these surgeries may impair it by damaging the nasal ciliated epithelia. This systematic review is designed with the objective of exploring the effect of turbinate surgery on MCC. Pubmed (Medline), the Cochrane Library, EMBASE, SciELO were analyzed. Four authors members of the YO-IFOS rhinology study group independently analyzed the articles. Extracted variables encompassed: sample size, age, indication for surgery, surgical technique, method used to measure mucociliary clearance, mucociliary transport time before and after surgery, and main outcome. 15 studies with a total population of 1936 participants (1618 patients excluding healthy controls) met the inclusion criteria. 9 studies could be combined in a metanalysis, wich revealed a non-statistically significant decrease of 3.86 min in MCTT after turbinate surgery (p = 0.06). The subgroup analysis of the 5 cohorts who underwent microdebrider turbinoplasty reached statistical significance under a random effect model, revealing a 7.02 min decrease in MCTT (p < 0.001). The laser turbinoplasty subgroup, composed of 4 cohorts, also reached significance, although the difference was lower than that for microdebrider turbinoplasty, 1.01 min (p < 0.001). This systematic review and meta-analysis suggests that turbinate surgery does not compromise mucociliary clearance. The available evidence also suggests that turbinate surgery with mucosa sparing techniques improves MCC, while with aggressive techniques it increases or remains the same. ... . (AU)

A pesar de que la cirugía turbinal tiene efectos positivos en la ventilación nasal, gran parte de estos procedimientos son agresivos con el epitelio respiratorio. Existen hipótesis que sugieren que la cirugía turbinal puede mejorar el aclaramiento mucociliar (AMC) al mejorar la rinitis, así como alterarlo al lesional el epitelio nasal. Esta revisión se diseña con el objetivo de explorar el efecto de la cirugía turbinal en el AMC. Se revisó Pubmed (Medline), the Cochrane Library, EMBASE, SciELO. 4 autores miembros de YO-IFOS grupo de estudio en rinología, analizaron de manera independiente los artículos. Las variables analizadas fueron tamaño muestral, edad, indicación quirúrgica, técnica quirúrgica, método de medición de AMC, AMC antes y después de la cirugía y resultado principal. Se incluyeron 15 estudios con 1936 participantes (1618 excluyendo controles sanos). 9 estudios fueron combinados en un metanálisis que demostró una diferencia no estadísticamente significativa de -3,86 minutos en AMC tras cirugía (p = 0,06). El análisis por subgrupos de las 5 cohortes sometidas a turbinoplastia con microdebridador si fueron estadísticamente significativas con una diferencia de -7,02 minutos (p < 0,001). El grupo sometido a laser (4 cohortes) también obtuvo diferencia estadística, aunque menor, -1,01 minutos (p < 0,001). Esta revision y metaanálisis sugiere que la cirugía turbinal no afecta al aclaramiento mucociliar. La evidencia disponible también sugiere que las técnicas menos agresivas con la mucosa mejoran el AMC, mientras que las agresivas podrían aumentarlo o no modificarlo. Este efecto beneficioso se observa desde el 1º al 3º mes postquirúrgico. Sin embargo, para poder obtener adecuadas conclusiones, debe existir un método estandarizado para medir el AMC, así como un método para describir adecuadamente la extensión quirúrgica. (AU)

A novel technique with butterfly splint for middle turbinate stabilization in sinus surgery.

OBJECTIVE: To assess the efficacy of newly designed butterfly splint with special technique for middle turbinate stabilization in preventing adhesion following bilateral endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP). STUDY DESIGN: Prospective, double-blind, randomized controlled. SETTING: University hospitals. METHODS: Following ESS, in cases of traumatized and/or unstable middle turbinates, newly designed butterfly plastic splint was randomly inserted in the middle meatus of one nasal side, while no splint was inserted in the other (control). Patients were followed up on after 1 week, 1 month, and 6 months. Endoscopic examination and a visual analog scale were used to evaluate each side of the nasal cavity for adhesion, crusting, pus, pain, nasal obstruction, and nasal discharge. RESULTS: Thirty patients (60 nasal sides) were included. For all investigated parameters, there was no significant difference between the splinted and non-splinted sides at the first week visit. Adhesion was found significantly less in the splinted sides (3%) than the non-splinted sides (27%) after 1 month (P = 0.038). The adhesion rate in the splinted sides remained 3% at the 3 month follow-up visit, however, in the non-splinted sides, the rate increased up to 30% (P = 0.007). Throughout the follow-up visits, all other investigated parameters remained statistically insignificant between both sides. CONCLUSIONS: The newly designed butterfly plastic splints to avoid middle turbinate adhesion is safe and effective in both reducing middle meatal adhesion with low complication rate in CRSwNP patients undergoing ESS and middle turbinate stabilization in its intermediate position.

Minimally Anterior Medial Maxillary Approach (MAMMA): a novel technique for a wide access to the maxillary sinus.

PURPOSE: To describe a novel endoscopic technique to approach the maxillary sinus (MS), the Modified Anterior Medial Maxillary Approach (MAMMA), preserving the inferior turbinate (IT) and the nasolacrimal duct (NLD). To perform radiological measurements and describe a case series to study the feasibility and limits of MAMMA. METHODS: Computed tomography (CT) scans (n = 150 nasal cavities) were used to calculate areas of the MAMMA to define surgical limits and extensions. Measurement of distances to critical anatomy landmarks and total area for the MAMMA were calculated. An instructional case illustrating the surgical technique and outcome was also included. RESULTS: Radiological analysis showed a mean distance from the Piriform Aperture (PA) to the anterior limit of the NLD of 1.03 ± 0.18 cm (range 0.59-1.48) and a mean distance from de PA to the posterior limit of the NLD of 1.57 ± 0.22 cm (range 1.02-2.11). The mean distance from the nasal floor to the Hasner's valve was 1.61 ± 0.27 cm (range 1.06-2.52) and the distance from the nasal floor to the insertion of the IT was 2.20 ± 0.36 cm (range 1.70-3.69). Finally, the mean total area for the MAMMA was 4.04 ± 0.52 cm2 (range 3.17-5.53). No complications or recurrence of the pathology were observed in operated patients. CONCLUSION: The MAMMA provides a wide surgical field of the MS walls comparable to more aggressive techniques, with preservation of the sinonasal and lacrimal function. MAMMA is an effective alternative to treat different MS pathologies including benign recurrent maxillary sinus tumors.

Nasal obstruction in a 14 year old girl caused by a huge middle turbinate mucocele appearing radiologically as an inverted papilloma.

Introduction: We present a case of a fourteen year old girl who presented with a large intra-nasal mass to the ENT team at a district general hospital in the UK. Presentation of case: The girl presented predominantly with nasal obstruction and some symptoms of allergic rhinitis. Imaging revealed a large lesion abutting the skull base and causing bony remodelling with marked septal deviation. Based both on CT and MRI imaging, the reporting (non-head and neck) radiologist suggested inverted papilloma as a differential diagnosis. Intra-operative exploration in fact revealed a very large left middle turbinate mucocele extending to the left frontal sinus. The mass was excised endoscopically without complications. Discussion: Although concha bullosa of the middle turbinate of the nose are common, development of a mucocele within them is far less common and for such a mucocele to develop to this size in a child is extremely rare. The egg shell lining of the lesion can be a tell-tale sign of their aetiology when taken alongside other radiological factors. This case highlights challenges in radiological diagnosis of intra-nasal masses in children, which can lead to delays and increased anxiety. Conclusion: When assessing nasal masses in children it is important to keep a wide differential due to the challenges of diagnosis. A close conversation should be had with local head and neck radiologists and, of course, where there is a unilateral nasal mass tissue sampling is essential and may be taken as part of a full excision where clinically indicated.

Incidental seromucinous hamartoma of the anterior nasal cavity presenting after episode of vestibular neuritis.

A woman in her 70s presented to primary care clinic complaining of acute onset dizziness for 1 day that was initially diagnosed as vestibular neuritis and treated with steroids. The next day, she presented to the emergency department with worsening symptoms. Imaging revealed no intracranial process; however, non-contrast CT imaging revealed a soft-tissue mass in the posterior ethmoid sinus. The vertigo completely resolved before an otolaryngologist surgically removed the nasal mass, which actually originated from the right cribriform plate and extended to the anterior middle turbinate head. The final pathology was consistent with seromucinous hamartoma.

Characteristics of Human Nasal Turbinate Stem Cells under Hypoxic Conditions.

This study investigated the influence of hypoxic culture conditions on human nasal inferior turbinate-derived stem cells (hNTSCs), a subtype of mesenchymal stem cells (MSCs). It aimed to discern how hypoxia affected hNTSC characteristics, proliferation, and differentiation potential compared to hNTSCs cultured under normal oxygen levels. After obtaining hNTSCs from five patients, the samples were divided into hypoxic and normoxic groups. The investigation utilized fluorescence-activated cell sorting (FACS) for surface marker analysis, cell counting kit-8 assays for proliferation assessment, and multiplex immunoassays for cytokine secretion study. Differentiation potential-osteogenic, chondrogenic, and adipogenic-was evaluated via histological examination and gene expression analysis. Results indicated that hNTSCs under hypoxic conditions preserved their characteristic MSC phenotype, as confirmed by FACS analysis demonstrating the absence of hematopoietic markers and presence of MSC markers. Proliferation of hNTSCs remained unaffected by hypoxia. Cytokine expression showed similarity between hypoxic and normoxic groups throughout cultivation. Nevertheless, hypoxic conditions reduced the osteogenic and promoted adipogenic differentiation potential, while chondrogenic differentiation was relatively unchanged. These insights contribute to understanding hNTSC behavior in hypoxic environments, advancing the development of protocols for stem cell therapies and tissue engineering.

Cultured Mesenchymal Cells from Nasal Turbinate as a Cellular Model of the Neurodevelopmental Component of Schizophrenia Etiology.

The study of neurodevelopmental molecular mechanisms in schizophrenia requires the development of adequate biological models such as patient-derived cells and their derivatives. We previously utilized cell lines with neural progenitor properties (CNON) derived from the superior or middle turbinates of patients with schizophrenia and control groups to study schizophrenia-specific gene expression. In this study, we analyzed single-cell RNA seq data from two CNON cell lines (one derived from an individual with schizophrenia (SCZ) and the other from a control group) and two biopsy samples from the middle turbinate (MT) (also from an individual with SCZ and a control). We compared our data with previously published data regarding the olfactory neuroepithelium and demonstrated that CNON originated from a single cell type present both in middle turbinate and the olfactory neuroepithelium and expressed in multiple markers of mesenchymal cells. To define the relatedness of CNON to the developing human brain, we also compared CNON datasets with scRNA-seq data derived from an embryonic brain and found that the expression profile of the CNON closely matched the expression profile one of the cell types in the embryonic brain. Finally, we evaluated the differences between SCZ and control samples to assess the utility and potential benefits of using CNON single-cell RNA seq to study the etiology of schizophrenia.

The effect of early radiofrequency turbinate reduction, intranasal steroid, and antihistamine H-1 on persistent allergic rhinitis: a randomized clinical trial

Abstract Objective: We aimed to evaluate the effect of radiofrequency turbinate reduction as an initial treatment on clinical improvement, inflammatory mediators, and remodeling process. Methods: Between July 2018- February 2020, 32 patients with moderate-severe persistent AR were randomly divided into 2 groups. Intervention group received radiofrequency turbinate reduction followed by intranasal steroid and Antihistamine H-1 (AH-1), control group received intranasal steroid and AH-1. Both groups were evaluated for clinical improvement (using visual analogue scale based on total nasal symptoms score, peak nasal inspiratory flow, and turbinate size using imageJ) after 4 and 8 weeks of treatment. Inflammatory mediators (ELISA from nasal secretions was performed to measure ECP, IL-5, and HSP-70) and remodeling markers (nasal biopsy followed by immunohistochemistry examination was performed to evaluate MMP-9, TIMP-1, and PAI-1) were evaluated in week 4. Results: Three patients dropped out of the study, resulting in 16 patients in intervention group and 13 patients in control group. At week 4, clinical response improved significantly in the intervention group compared to control group (Chi-Square test, p<0.05). Compared to control, intervention group experienced a reduction of IL-5 and no significant change in ECP level (Mann Whitney test, p>0.05). Reduction in the ratio of MMP-9/TIMP-1 were significantly higher in intervention group (unpaired t-test, p< 0,05). Meanwhile, increase in HSP-70 in the intervention group was slightly lower than in control group, but the difference with control group was not significant (Mann Whitney test, p>0.05). Conclusion: Early radiofrequency turbinate reduction followed by pharmacotherapy given to persistent moderate-severe AR patients give more improvement only in early clinical symptoms and reduce MMP-9/TIMP-1 ratio, thus it might be suggested as one of the adjuvant therapies for the management of moderate-severe persistent AR. However, further investigation with a larger sample size and longer follow-up period is needed. Level of evidence: 1B.

Cirugía de cornetes inferiores en población pediátrica: ¿Cómo, cuándo y por qué? / Inferior turbinate surgery in pediatric population: How, when and why?

La hipertrofia de cornetes inferiores representa una de las principales causas de obstrucción nasal en pacientes pediátricos. En estudios recientes se ha observado un aumento significativo de esta patología en niños que no responden a terapia médica. La evidencia disponible recomienda la cirugía como tratamiento de elección en la obstrucción nasal refractaria en niños con cornetes hipertróficos. Sin embargo, hasta la fecha no existen criterios formales de derivación a cirugía en la población pediátrica y los estudios en infantes son limitados. Al mismo tiempo, la falta de consenso no ha permitido recomendar una técnica quirúrgica en estos pacientes por sobre otras. Por lo tanto, se hace necesario profundizar las diferentes alternativas disponibles, considerando y optando por aquellas que presenten mayores beneficios y menor riesgo de complicaciones. En la presente revisión se estudió la evidencia disponible hasta el momento sobre este tema en la población pediátrica y además se realizó un análisis de la efectividad y complicaciones de las diferentes técnicas disponibles.

Inferior turbinate hypertrophy represents one of the leading causes of nasal obstruction in pediatric patients. Recent studies have observed a significant increase in turbinate hypertrophy in children that does not respond to medical treatment. The latest evidence recommends inferior turbinoplasty for treating nasal obstruction in children with hypertrophic turbinates. However, until today there are no formal criteria for referral to surgery in the pediatric population, and studies in children are limited. At the same time, the absence of consensus has not allowed the recommendation of one surgical technique over others in these patients. This is why it is necessary to deepen the available alternatives and choose those with more significant benefits and a lower risk of complications. In this review, we study available evidence about this topic in the pediatric population and analyze the effectiveness and complications of different known techniques.

Angiomatous Polyp Originating From the Inferior Turbinate: A Variant of the Sinonasal Polyp.

Angiomatous polyps are an uncommon subtype of sinonasal polyps, characterized by extensive vascular proliferation and ectasia. The authors report the first case of angiomatous polyp originating from the inferior turbinate, which is a variant of the sinonasal polyp.

Human papillomavirus-related multiphenotypic sinonasal carcinoma: A report of two patients and review of the literature.

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC) is a recently described sinonasal tract tumor that is associated with high-risk HPV subtype infection. Despite histological features that are suggestive of a high-grade malignant tumor, the prognosis of HMSC is relatively good; however, the clinical features of this tumor are poorly understood. Here, we describe two patients with HMSC. The first was initially diagnosed with adenoid cystic carcinoma of the right nasal cavity; the tumor was extirpated via endoscopic endonasal surgery. Seventy-four months later, the tumor recurred in the right inferior turbinate and was diagnosed as HMSC after biopsy, whereupon it was resected en block via endoscopic endonasal surgery. No adjuvant therapy was administered during either episode; moreover, no recurrences have occurred during the 44 months since the second operation. The second patient was diagnosed with HMSC based on the biopsy of the tumor occupying the left nasal cavity. The tumor was completely resected under endoscopic endonasal surgery, and no adjuvant therapy was administered. There has been no recurrence for 15 months after the operation. Herein, we also review the clinical features of this tumor type based on 69 previously reported cases as well as our patients.

Nasal nerve ablation, nasal swell body and inferior turbinate reduction for nasal obstruction and congestion relief.

OBJECTIVE: Nasal obstruction and congestion can occur because of turbinate and septal variations with or without rhinitis. A combined treatment for nasal obstruction and congestion was examined retrospectively in cases where the nasal swell body was addressed with inferior turbinectomy, with or without posterior nasal nerve ablation. METHODS: A 940 nm laser was utilised for contact (nasal swell body, septum and inferior turbinate) and non-contact (posterior nasal nerve) ablation. Total Nasal Symptoms Score, visual analogue scale pain score, complications and procedure location (office vs operating theatre) were recorded. RESULTS: All 242 patients underwent nasal swell body reduction with inferior turbinate reduction, and 150 had posterior nasal nerve ablation also. No laser complications were observed. An 80 per cent reduction in medication usage was noted. Total Nasal Symptoms Score decreased by 73 per cent; rhinorrhoea and congestion scores decreased by 54 per cent and 81 per cent respectively. Crusting, epistaxis and infections were minimal, and resolved within two weeks. CONCLUSION: Nasal swell body with inferior turbinate reduction, with or without posterior nasal nerve ablation, is a new method of treating nasal obstruction and congestion. Laser posterior nasal nerve ablation can be utilised as a complementary tool to deliver anatomical obstruction relief.
