RESUMEN
BACKGROUND: Surgical treatment is recommended for patients with severe allergic rhinitis (AR) refractory to medical treatment. Endoscopic posterior nasal neurectomy (PNN) is primarily performed to improve rhinorrhea in severe perennial AR, however studies on its long-term prognosis are lacking. AIMS/OBJECTIVES: This study aimed to investigate the long-term prognosis of PNN. MATERIALS AND METHODS: A questionnaire survey was administered to 17 patients (12 men and 5 women) at least 1 year after PNN. Nasal symptoms and medications, as well as patient satisfaction with surgery at the time of survey, were scored. Furthermore, scores were compared between patients with postoperative periods of >5 years and <5 years. RESULTS: Nasal symptoms and medication scores significantly improved after surgery. There was no significant difference between patients with a postoperative period of >5 years and <5 years in both preoperative and postoperative nasal symptoms and medication scores. No correlation was found between patient satisfaction with surgery and postoperative period. CONCLUSIONS AND SIGNIFICANCE: PNN improved nasal symptoms and medication scores in patients with severe perennial AR. Furthermore, the study results suggest that the long-term effect of PNN for perennial AR lasts for >5 years. J. Med. Invest. 71 : 62-65, February, 2024.

BACKGROUND: Nasal obstruction, triggered by allergic rhinitis, often does not resolve with allergen-specific immunotherapy (AIT) alone, thus inferior turbinate reduction surgery (ITR) may be required. This study aims to investigate the impact of combined treatment on nasal obstruction, as evidence is currently limited. METHODOLOGY/PRINCIPAL: A retrospective cohort study of perennial allergic rhinitis patients experiencing nasal obstruction and undergoing ≥12 months AIT was conducted. Two groups were derived, those undergoing AIT-with or without an ITR. Patient reported nasal obstruction (evaluated with questionnaires) and nasal airway function (Nasal Peak Inspiratory Flow [NPIF] and Nasal Airflow Resistance [NAR]) were monitored. The change from baseline to 12 months post-treatment in each group were compared. RESULTS: A total of 118 patients (33.71 ± 14.43 years, 41.5% female) were recruited, 72% had AIT and 28% AIT&ITR. At baseline, the AIT&ITR group had a higher level of nasal obstruction (>moderate%; 63.6% vs 52.9%, P = .048). Post treatment, AIT&ITR group reported greater reduction in nasal obstruction (>1 category change: 75.8% vs 48.2%, P = .002). Similarly, the AIT&ITR group had greater improvement in nasal function by NPIF (-13.9 ± 110.3 L/minute vs -3.4 ± 78.1 L/minute, P = .049) and NAR (-0.120 ± 0.342 Pa/cm³/second vs -0.093 ± 0.224 Pa/cm³/second, P = .050). CONCLUSIONS: Allergic rhinitis patients, with moderate to severe nasal obstruction, who undergo combined AIT&ITR have greater relief of nasal obstruction and improved airflow analysis compared to AIT alone.

Recurrence of allergic fungal rhinosinusitis (AFRS) is well recognized. However, there is scarcity in the literature describing involvement of the non-diseased sinuses. We aimed to evaluate the recurrence forms of unilateral AFRS as well as to study the possible predictor factors of developing the disease in the contralateral side. Patients with exclusive unilateral AFRS from (2010 to 2015) were enrolled in multi-institutional case-control study. All patients were evaluated after endoscopic sinus surgery for recurrence. Patient's records were reviewed for demographics, medical treatment, and clinical, radiological, and surgical data. A total of 68 patients were identified. Delayed contralateral involvement after the initial surgery was found in 30.8% with mean duration of recurrence 16.9 months. A significant association was found with the presence of pre-operative contralateral symptoms and signs of inflammation (OR 3.49, 95% CI 1.19-10.22, p value 0.02). Post-operative use of budesonide irrigation was associated with less contralateral involvement (OR 0.11, 95% CI 0.01-0.87, p value 0.01). Association of other variables like: comorbidities, perioperative use of systemic steroid, radiological signs, extent of surgery, additional surgery to the contralateral side, and post-operative use of systemic steroids did not show statistical significance. Involvement of the contralateral sinuses in 30% of unilateral AFRS cases is considered significant. The non-diseased sinuses should be involved in the routine endoscopic examination and post-operative treatment. Further studies are necessary to investigate the possibility of prophylactic surgical intervention of the non-diseased sinuses.

OBJECTIVE: To evaluate the effect of two surgical methods on treatment of allergic rhiniti complicated with nasal septum deviation. METHOD: Eighty-seven cases of allergic rhiniti complicated with nasal septum deviation were divided into 2 groups according to the degree of mucosal hypertrophy and hyperplasia of bone in inferior turbinate. They were treated by resection of nasal septum deviation combined with temperature-controlled radio-frequency, or combined with partial submucoperiosteous resection of inferior turbinate bone. The Lanzhou standard (2004) and nasal airway resistance were used to evaluate the efficacy. RESULT: After one year follow-up time, the nasal resistance was significantly decreased and the effective rates were greater than 88% in each group. CONCLUSION: Both of the two surgical methods can significantly depress the nasal resistance and improve the allergic symptoms, which shows good effect.

This study was aimed at understanding the histopathologic changes that occur in the nasal mucosa of patients with perennial allergic rhinitis after high-intensity focused ultrasound (HIFU) treatment. Biopsy specimens of the inferior turbinate mucosa were taken from 11 PAR patients before, immediately after and 1 y after HIFU treatment. Morphometric analysis revealed that the density of eosinophils and other inflammatory cells increased immediately after treatment and then were decreased significantly 1 y post-treatment. Submucosal glands were swollen and venous sinusoids were dilated, but there was no statistically significant change in their density, immediately after treatment. However, both glands and venous sinusoids significantly decreased in number 1 y after HIFU treatment. The ciliated epithelium or basement membrane of the nasal mucosa was well preserved at all stages. In conclusion, HIFU is a tolerable and effective treatment to reduce inflammation of the inferior turbinate mucosa in patients with perennial allergic rhinitis.

Fungal load colonization may modify the classic eosinophilic inflammation in allergic fungal rhinosinusitis (AFRS). We aimed to evaluate the impact of fungal load on diagnosis and outcome of AFRS. In the present cohort study fungal load differences were determined prospectively according to Gomori methenamine silver (GMS) fungal stained (histopathological and cytological examination) with the tenacious mucus, cheesy clay-like materials and sinus mucosa/polyps in 12 AFRS patients. Two groups with different fungal loads, AFRS with (six patients) and without (six patients) high fungal loads (HFL) were evaluated for nasal endoscopic score, paranasal sinuses CT score, histopathological and immunohistochemical changes. Endoscopic outcome scoring differences were evaluated for 1 year after endoscopic sinus surgery and 1 month oral corticosteroids treatment. No differences were observed between both groups (AFRS with/without HFL) concerning the total CT score and opacification features (P > 0.05). Eosinophils and CD3 + CD8 + T cell were dominant in both groups. More edema and less fibrosis were observed in HFL group. Gliotoxin producers Aspergilli were present in all HFL in comparison to 5/6 (83.3%) in cases without HFL. Fewer patients 1/6 (16.6%) and less number of recurrences/year 0.1 ± 0.4 occurred in the AFRS with HFL compared to the AFRS without HFL [5/6 (83.3%) and 1.16 ± 0.7) (P = 0.021 and 0.023, respectively]. In addition to mucus and mucosal tissues, cheesy clay-like materials must be assessed in AFRS cases. Although patients of AFRS with HFL had negligible clinical differences from ordinary AFRS without HFL, they had better outcome after treatment.

OBJECTIVES: To examine the anatomical features of the anterior opening of the vidian canal using three-dimensional (3D) computed tomography (CT) images of the bone. METHODS: We reviewed 62 patients who had undergone bilateral vidian neurectomies. One hundred and twenty-four vidian canals and their surrounding anatomies were analyzed. 3D images were reconstructed using algorithms and compared with conventional two-dimensional (2D) CT images. RESULTS: A bony prominence that overlaid the vidian canal along the sphenoid sinus floor was found in 60 (48.39 %) canals. Pneumatization of the pterygoid process was observed in 45 sides (36.29%). No significant discrepancy was found in detecting these variances between the 2D and the 3D images. The presence of a surgically favorable gap between the palatine and the sphenoid bone was seen in 25 sides (20.16%) without significant association with pterygoid process pneumatization or vidian canal protrusion. This gap was not identified on the 2D CT scans. CONCLUSION: 3D CT reconstruction images of bone provide superior delineation of the gap between the palatine and the sphenoid bone, which is a critical variation for vidian neurectomy. This useful method may contribute to better prediction and guidance of the surgical approach to the vidian canal and pterygopalatine fossa.

BACKGROUND: Surgical treatment for inferior turbinate (IT) is selected to treat severe allergic rhinitis (AR) that is unresponsive to conservative treatment. This study aimed to determine the clinical effects of outpatient submucosal IT surgery (OSITS) on patients with severe AR. METHODS: Between January 2008 and August 2012, 95 patients with severe AR who underwent OSITS at the Department of Otolaryngology, Hyogo College of Medicine, were retrospectively analyzed. There were 53 men and 42 women. Their mean age was 27 years (11-75 years). OSITS was bilaterally performed using a bipolar radiofrequency electrocautery under local anesthesia. Symptoms, QOL, and physical findings were evaluated using scores from both pre- and postoperative periods (average: 12.4 months), according to Practical Guideline for the Management of AR in Japan 2009. RESULTS: In perennial AR, all mean scores of nasal symptoms, QOL, and physical findings significantly improved after OSITS (p < 0.05, n = 83). Nasal obstruction, sleep problems, and IT congestion were the most strongly affected. Eye symptoms were not influenced by OSITS. OSITS also showed significant effects on nasal obstruction and IT congestion in seasonal AR (p < 0.05, n = 12), but not sneezing, nasal discharge, and QOL. In terms of the efficacy, OSITS was beneficial in 90% of perennial AR cases and 75% of seasonal AR cases. Epistaxis (1%), vestibulitis (1%), and IT atrophy (4%) were observed after OSITS. CONCLUSIONS: These data indicate that OSITS using radiofrequency electrocautery could be a beneficial therapeutic option in patients with severe AR.

OBJECTIVE: In order to explore the effect of plasma radiofrequency ablation on nasal mucosa provocative tests for allergic rhinitis. METHOD: Eighty patients with allergic rhinitis were enrolled in this study. The nasal mucosa provocative tests and nasal airway resistance and subjective nasal patency feeling were studied before and after plasma radiofrequency ablation treatment. The correlation of subjective and objective nasal patency was evaluated. RESULT: The preoperative nasal mucosa provocative test of all the patients allergic to mites were positive. The nasal mucosa provocative tests were negative within 72 patients, while remained positive in eight patients after 3 months of operation. The nasal airway resistance decreased from (0.772 +/- 0.224) kPa x s/L to (0.221 +/- 0.112) kPa x s/L after surgery (P < 0.01); Visual analog scale decreased from 7.0 +/- 2.0 to 2.5 +/- 1.5 after 3 months of operation (P < 0.01). CONCLUSION: Due to its ability to reduce the sensitivity of the nasal mucosa, nasal airway resistance and improve subjective feeling of nasal patency, plasma radiofrequency ablation is effective for the treatment of patients with allergic rhinitis.

BACKGROUND: Chronic sinusitis is one of the most common otolaryngological diagnoses. Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis can easily be misdiagnosed and treated as chronic sinusitis, causing continuing harm. AIM: To better identify and characterise these two subgroups of patients, who may suffer from a systemic disease requiring multidisciplinary treatment and prolonged follow up. METHODS: A retrospective, longitudinal study of all patients diagnosed with allergic fungal sinusitis or eosinophilic mucin rhinosinusitis within one otolaryngology department over a 15-year period. RESULTS: Thirty-four patients were identified, 26 with eosinophilic mucin rhinosinusitis and 8 with allergic fungal sinusitis. Orbital involvement at diagnosis was commoner in allergic fungal sinusitis patients (50 per cent) than eosinophilic mucin rhinosinusitis patients (7.7 per cent; p < 0.05). Asthma was diagnosed in 73 per cent of eosinophilic mucin rhinosinusitis patients and 37 per cent of allergic fungal sinusitis patients. CONCLUSION: Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis have the same clinical presentation but different clinical courses. The role of fungus and the ability to confirm its presence are still problematic issues, and additional studies are required.

OBJECTIVES/HYPOTHESIS: Microdebrider-assisted inferior turbinoplasty (MAIT) has become a popular method for relieving symptoms of allergic rhinitis and can be performed intraturbinally or extraturbinally. The objective of this study was to evaluate and compare the long-term efficacy of these two methods. STUDY DESIGN: Prospective randomized study. METHODS: Sixty patients diagnosed with perennial allergic rhinitis were selected. Thirty patients were treated with intraturbinal MAIT (group 1) and 30 patients were treated with extraturbinal MAIT (group 2). Postoperative changes in nasal obstruction, rhinorrhea, sneezing, nasal itching, and postnasal drip were evaluated 3, 6, and 12 months postoperatively. The cross-sectional area of the second notch and nasal cavity volume were compared at 12 months. The operation time, duration of crust formation, and postoperative bleeding were also compared. RESULTS: All symptoms improved significantly in both groups at 3, 6, and 12 months. However, when improvement of rhinorrhea, sneezing, and nasal itching was compared, improvement was statistically significant in group 2 at 12 months. Acoustic rhinometry demonstrated a significant increase in the cross-sectional area of the second notch and nasal cavity volume in both groups, which did not differ significantly between the two groups at 12 months. The operation time and duration of crust formation were longer in groups 1 and 2, respectively. The incidence of postoperative bleeding was higher in group 2. CONCLUSION: Although both methods showed significant improvement, extraturbinal MAIT seemed more effective for long-term relief of allergic symptoms. However, the advantages and disadvantages of each method should be considered before choosing the surgical technique.

OBJECTIVE: To investigate the expression of interleukin (IL) 17A in Chinese patients with chronic rhinosinusitis (CRS) and analyse its correlation with clinical parameters. METHODS: Patients undergoing functional endoscopic sinus surgery and matched controls were included in this retrospective study. Clinical assessments (using a visual analogue scale of symptom severity, Johansson endoscopic score and Lund-Mackay computed tomography score) were performed preoperatively. Mucosal specimens were analysed for inflammatory infiltration and IL-17A expression, using immunohistochemistry. RESULTS: In total, 40 patients undergoing functional endoscopic sinus surgery and 16 controls were included in the study. IL-17A levels were significantly higher in tissues from patients with CRS (with or without nasal polyps) than in control tissues. In CRS, IL-17A expression tended to be higher in tissues with infiltrating neutrophils than in those with infiltrating eosinophils, but this difference was not significant. IL-17A expression in CRS was positively correlated with symptom severity, endoscopic findings and radiological appearance. CONCLUSIONS: Expression of IL-17A was higher in Chinese patients with CRS than in controls, and was associated with infiltrating inflammatory cells, symptom severity, endoscopic findings and radiological appearance. These findings suggest that IL-17A may play a role in CRS pathogenesis and remodelling of nasal polyps.

INTRODUCTION: Until recently, Vidian neurectomy had been applied mainly in intractable vasomotor rhinitis and severe perennial allergic rhinitis. Although the results were excellent, the operation has not been applied recently because of the adverse events such as xerophthalmia and trigeminal neuralgia. To resolve these problems, a new surgical technique, posterior nasal neurectomy, was developed. In this report, we examined the effectiveness of posterior nasal neurectomy combined with the inferior turbinate surgery for severe perennial allergic rhinitis and intrinsic rhinitis by questionnaire. PATIENTS AND METHODS: Twenty patients who had undergone posterior nasal neurectomy combined with the inferior turbinate surgery between April in 2005 and March in 2009 were enrolled. Numeric Rating Scale was used to evaluate clinical symptoms and quality of life (QOL) of pre- and postsurgery. Frequency of medication (oral administration and nasal spray) was also evaluated. RESULTS: Questionnaires were collected from 17 patients. As for all patients but one, the surgery significantly reduced rhinorrhea, nasal obstruction, and sneezing. Furthermore, QOL for many symptoms such as sleep disorder and malaise/feebleness was also significantly improved after the surgery. Eighty-one percent of patients were satisfied with the surgery. CONCLUSION: Posterior nasal neurectomy combined with the inferior turbinate surgery is effective in alleviating clinical symptoms and improving QOL in the patients with severe perennial allergic rhinitis and intrinsic rhinitis, although a longer follow-up is needed.

IMPORTANCE: Clinical management of nasal airway obstruction (NAO) in patients with and without nasal allergic symptoms and nasal valve collapse (NVC). OBJECTIVE: To examine the impact that autologous alar batten grafts have on patients with NAO owing to NVC and their affect on nasal steroid use and allergic symptoms. DESIGN: A prospective study. SETTING: Indiana University Medical Center, Indianapolis. PARTICIPANTS: Patients with NAO due to NVC with or without symptoms of nasal allergic symptoms. INTERVENTIONS: All of the patients had placement of autologous batten grafts during the study period. STUDY SELECTION: Prospective study of patients with dynamic NVC undergoing alar batten graft treatment. DATA EXTRACTION: Nasal Obstruction Symptom Evaluation survey preoperatively and postoperatively, prospective outpatient questionnaire to determine use of nasal steroids and presence of nasal allergic symptoms preoperatively and postoperatively. RESULTS: A total of 126 patients underwent surgical intervention for the treatment of NAO due to NVC. All of these patients were using nasal steroid sprays, and 78 patients (62%) also reported nasal allergic symptoms at their initial presentation. At 6-month and 1-year postoperative evaluations, 118 (94%) and 122 (97%), respectively, reported significant improvement of their NAO, regardless if they had presented with or without allergic nasal symptoms. Sixty-two of the 78 patients (79%) who initially presented with NAO owing to NVC and nasal allergic symptoms preoperatively reported significant improvement in their NAO and nasal allergic symptoms postoperatively. Eight of 126 (6%) restarted their use of nasal steroids postoperatively. All 8 of these patients reported nasal allergic symptoms preoperatively. No patients in the nonallergic group continued the use of nasal steroids postoperatively. There was no increase in nasal steroid use at the 12-month follow-up visit. CONCLUSIONS AND RELEVANCE: Nasal airway obstruction due to NVC in patients can be surgically treated with autologous alar batten grafts. In addition, the use of alar batten grafts may improve NAO in patients with nasal allergic symptoms and reduces their use of nasal steroids. These results support the idea of potential surgical repair of the nasal valve to treat patients with NAO due to nasal allergic symptoms and NVC. LEVEL OF EVIDENCE: 4.

BACKGROUND: Catgut implantation at acupoints has been used in China to treat allergic rhinitis (AR) for a long time. However, its efficacy and safety in the treatment of AR is controversial due to the poor quality of the clinical trial of this therapy. This study aims to identify whether catgut implantation at acupoints is indeed an effective and safe treatment for patients with persistent or intermittent allergic rhinitis (PER or IAR) by comparing with sham catgut implantation treatment. METHODS AND DESIGN: This study compares real versus sham catgut implantation at acupoints in 242 patients with a history of PER or IAR and with a positive skin prick test (SPT). The trial will be conducted in the Teaching Hospital of Chengdu University of Traditional Chinese Medicine. In the study, patients will be randomly assigned by computer-generated randomization list into two groups and assessed prior to treatment. Then, they will receive two sessions of treatments (once per 2 weeks) for 4 consecutive weeks and have a follow-up phase of 12 weeks. The administration of catgut implantation (or sham-control) at acupoints follows the guidelines for clinical research on acupuncture (WHO Regional Publication, Western Pacific Series No.15, 1995), and is performed double-blindly by a well-trained physician in acupuncture. The main outcome measures include the primary and secondary indicators. Primary indicators are subjective symptoms scores evaluated by visual analogue scales (VAS) and Rhinoconjunctivitis Quality of Life Questionnaires (RQLQ). The secondary indicators are the results of laboratory examinations, such as serum allergen-specific IgE, nasal inflammatory cells counts (mast cells, eosinophils, and T cells) and nitric oxide concentration in nasal excretion. The use of anti-allergic medication will also be recorded as one of the secondary indicators. Furthermore, adverse events will be recorded and analyzed. If any participants withdraw from the trial, intention-to-treat analysis (ITT) and per-protocol (PP) analysis will be performed. DISCUSSION: The important features of this trial include the randomization procedures, large sample, and a standardized protocol of catgut implantation at acupoints. This trial will be the first study with a high evidence level in China in order to assess the efficacy and safety of catgut implantation at acupoints in treatment of AR following a randomized, double-blind sham-controlled method. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR-TRC-12002191.

OBJECTIVE: To evaluate the therapeutic effect of nasal coblation plasma surgery for the treatment of persistent allergic rhinitis (PAR). METHODS: One hundred patients with mite-sensitized moderate to severe PAR who underwent nasal coblation plasma surgery (inferior turbinoplasty plus nasal agger ablation) were enrolled in this study. There were 68 male and 32 female patients aged 16 to 62 years (mean, 36.3 years). The visual analogue scale (VAS) for global rhinitis symptoms, nasal provocation test (NPT), anterior rhinomanometry, and T&T olfactometry were used to assess the short-term outcomes, preoperatively and postoperatively at the end of three months after surgical procedure. SPSS19.0 software was applied for statistical analysis. RESULTS: At three months after treatment, the total nasal symptom VAS scores significantly decreased from 7.0 ± 2.0 to 2.5 ± 1.5 (X(-) ± s; t = 18.00, P = 0.0001). All patients were allergic to house dust mites with positive NPT before treatment. At three months from the coblation intervention, 88.0% of the patients changed from positive NPT to negative, while 12.0% remained as positive. There was a significant reduction in total nasal resistance, which diminished from 0.772 ± 0.224 to 0.221 ± 0.112 kPa·s·L(-1) after treatment (t = 22.00, P = 0.0001). Preoperative olfactory tests showed hyposmia in 31.0% of the patients, with 22 cases for slight and 9 cases for moderate disorder. Three months after treatment, 13.0% were diagnosed as hyposmia, with 7 cases for slight and 6 cases for moderate disorder (χ(2) = 10.44, P = 0.005). CONCLUSION: Nasal coblation plasma surgery provides favorable short-term outcomes in terms of remarkable improvement in nasal symptoms, hyperreactivity of nasal mucosa, nasal flow and olfactory function in patients with moderate to severe PAR, but long-term effect needed further observation.
