Objectives: The aim of this controlled follow-up study was to compare the need for revision surgery, long-term efficacy, and satisfaction in chronic rhinosinusitis patients who had undergone maxillary sinus operation with either balloon sinuplasty or traditional endoscopic sinus surgery (ESS) technique. Methods: Thirty-nine ESS patients and 36 balloon patients of our previously described cohort, who had been primarily operated in 2008 to 2010, were contacted by phone. Symptoms, satisfaction, and need for revision surgery were asked. In addition, we collected data of patients who had undergone primary maxillary sinus balloon sinuplasty in the Helsinki University Hospital during the years 2005 to 2019. As a control group, we collected data of patients who had undergone primary maxillary sinus ESS at 3 Finnish University Hospitals, and 1 Central Hospital in years 2005, 2008, and 2011. Results: Altogether, 77 balloon patients and 82 ESS patients were included. The mean follow-up time was 5.3 years in balloon group and 9.8 years in ESS group. Revision surgery was performed on 17 balloon patients and 6 ESS patients. In the survival analysis, the balloon sinuplasty associated significantly with a higher risk of revision surgery compared to ESS. According to the phone interviews, 82% of ESS patients and 75% of balloon patients were very satisfied with the primary operation. Conclusion: Although the patient groups expressed equal satisfaction and change in symptoms after the operations, the need for revision surgery was higher after balloon sinuplasty than after ESS. This should be emphasized when counselling patients regarding surgical options.

Objectives The diagnosis of chronic rhinosinusitis without nasal polyps (CRSsNP) and distinguishing it from allergic rhinitis is difficult. Yet, early detection of CRSsNP is important to prevent progressive and severe chronic rhinosinusitis. Our aim was to compare diagnostic accuracy of symptoms, endoscopy, and imaging signs of CRSsNP and allergic rhinitis -only phenotypes. Setting Prospective controlled follow-up study. Participants Forty-two nonsmoking patients visiting tertiary care due to CRSsNP and 19 nonsmoking volunteer controls with allergic rhinitis filled a symptoms questionnaire and underwent nasal endoscopy off-seasonally. All CRSsNP patients underwent computed tomography scans of paranasal sinuses. All the allergic rhinitis control subjects and 14 of the CRSsNP patients underwent sinus magnetic resonance imaging. Results Radiologic Lund–Mackay score, duration of symptoms, visual analogue scale scores of symptoms, and Sinonasal Outcome Test 22 were significantly higher in the CRSsNP group compared to allergic rhinitis control group. These factors also correlated in part with each other. Endoscopic score did not correlate with other factors, nor did it differ between CRSsNP and allergic rhinitis groups. The highest area under curve value was demonstrated for visual analogue scale score of facial pain/pressure (0.93) and score ≥4/10 showed 60% sensitivity and 95% specificity for detecting CRSsNP group ( P Conclusions CRSsNP phenotype could be primarily distinguished from allergic rhinitis by higher facial pain/pressure score and secondarily by radiologic sings of obstructed ostiomeatal complex and higher Lund–Mackay score. Endoscopic score has limited value in distinguishing CRSsNP from allergic rhinitis.

BackgroundAsthma and chronic rhinosinusitis with nasal polyps (CRSwNPs) are coexisting diseases that are multifactorial. The rural environment seems to protect from atopy, but its relation with nonatopic airway inflammations has been less investigated. Indoleamine 2,3-dioxygenase (IDO) is an enzyme involved in the catabolism of the essential amino acid tryptophan (Trp) to kynurenine (Kyn). Low IDO activity has been previously observed in atopy and asthma. The objective was to investigate the relationships of IDO activity, eosinophils, and cofactors during asthma and/or CRSwNPs.MethodsA Finnish population-based cohort of adult asthmatic patients (n = 245) and nonasthmatic patients (n = 405) was used. The presence of asthma and atopy were based on patient history and standardized diagnostic tests. The presence of acetyl salicylic acid intolerance, doctor-diagnosed NPs, and countryside environment during childhood were based on a questionnaire report. Serum IDO activity was evaluated by assessing the Kyn/Trp ratio by liquid chromatography.ResultsLow IDO activity was associated significantly with atopy, CRSwNPs, and an urban background. IDO activity did not correlate with pulmonary function. As expected, CRSwNPs was more frequent among asthmatic patients. A rural background has a protective effect from atopy and atopic asthma but it did not affect the prevalence of CRSwNPs or nonatopic asthma.ConclusionLow IDO activity might result from the urban environment and influence the development of the atopic phenotype. On the other hand, low IDO activity, found in CRSwNPs, does not seem to be related to the urban background an us may result from other, still unknown, factors.

Background Endoscopic sinus surgery (ESS) is considered after medical therapy failure of chronic rhinosinusitis (CRS). The balloon sinuplasty dilates the natural ostium without moving mucosa or bone. It still lacks evidence from randomized controlled trials. The aim of this retrospective controlled study was to compare the symptom outcomes after maxillary sinus surgery with either the ESS or the balloon sinuplasty technique. No previous or additional sinonasal operations were accepted. Methods Two hundred eight patients with CRS without nasal polyps underwent either balloon sinuplasty or ESS. The patients who met with the inclusion criteria (n = 45 in ESS group and n = 40 in balloon group) replied to a questionnaire of history factors, exacerbations, and a visual analog scale (VAS) scoring of the change in symptoms, on average 28 ± 6 (mean ± SD) months postoperatively. Results The groups were identical in the response rate (64%), patient characteristics, and the improvement in all of the asked symptoms. Patients with CRS-related comorbidity and/or present occupational exposure had a statistically significantly better symptom reduction after ESS than after balloon sinusotomy. Moreover, the balloon sinusotomy group reported a statistically significant higher number of maxillary sinus punctures and antibiotic courses during the last 12 months. Conclusion ESS might be superior to balloon sinuplasty, especially in patients with risk factors. There is a need to perform more controlled studies on the treatment choices of CRS.

BackgroundChronic rhinosinusitis (CRS) is characterized by persistent inflammation of the nasal and paranasal mucosa with numerous emigrated leukocytes. L-Selectin on leukocytes and its endothelial glycosylated ligands initiate leukocyte infiltration into inflamed tissues. Endoscopic sinus surgery (ESS) is the major approach for restoring sinus physiology after failure of conservative therapy; however, the effect of enlarging the maxillary sinus ostium is still unknown. Here, we compared two histological markers of local inflammation, the number of mucosal eosinophils, and the expression of endothelial L-selectin ligands, with clinical outcomes after enlarging or saving the maxillary sinus ostium.MethodsTwenty-three patients with CRS underwent uncinectomy on one side and additional middle meatal antrostomy on the other side. Maxillary sinus mucosa biopsy specimens from these patients and nine healthy subjects were taken for immunohistochemical evaluations of the number of mucosal eosinophils and endothelial L-selectin ligands. Also, symptoms and mucociliary clearance were measured.ResultsThe postoperative reduction of the endothelial L-selectin ligands was independent of the operation technique. There was a correlation between postoperative number of mucosal eosinophils and symptom score, which was also independent of the surgical technique. The postoperative decrease of mucosal eosinophils, as well as the correlation of the intraoperative eosinophils with the postoperative symptom score, was found only on antrostomy side.ConclusionESS decreases the expression of endothelial L-selectin ligands, which might lead to decreased eosinophil traffic into maxillary sinus mucosa, putatively more when enlarging the maxillary sinus ostium. Both intra- and postoperative low number of eosinophils seem to be indicators of good subjective recovery.
