[CF Lung Disease - a German S3 Guideline: Pseudomonas aeruginosa]. / S3-Leitlinie: Lungenerkrankung bei Mukoviszidose ­ Pseudomonas aeruginosa.

Cystic Fibrosis (CF) is the most common autosomal recessive genetic multisystemic disease. In Germany, it affects at least 8000 people. The disease is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene leading to dysfunction of CFTR, a transmembrane chloride channel. This defect causes insufficient hydration of the airway epithelial lining fluid which leads to reduction of the mucociliary clearance.Even if highly effective, CFTR modulator therapy has been available for some years and people with CF are getting much older than before, recurrent and chronic infections of the airways as well as pulmonary exacerbations still occur. In adult CF life, Pseudomonas aeruginosa (PA) is the most relevant pathogen in colonisation and chronic infection of the lung, leading to further loss of lung function. There are many possibilities to treat PA-infection.This is a S3-clinical guideline which implements a definition for chronic PA-infection and demonstrates evidence-based diagnostic methods and medical treatment in order to give guidance for individual treatment options.

Magnetic Resonance Imaging of Pulmonary and Paranasal Sinus Abnormalities in Children with Primary Ciliary Dyskinesia Compared to Children with Cystic Fibrosis.

Rationale: Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are characterized by inherited impaired mucociliary clearance leading to chronic progressive lung disease as well as chronic rhinosinusitis (CRS). The diseases share morphological and functional commonalities on magnetic resonance imaging (MRI) of the lungs and paranasal sinuses, but comparative MRI studies are lacking. Objectives: To determine whether PCD shows different associations of pulmonary and paranasal sinus abnormalities on MRI and lung function test results in children (infants to adolescents) compared with children with CF. Methods: Eighteen children with PCD (median age, 9.5 [IQR, 3.4-12.7] yr; range, 0-18 yr) and 36 age-matched CF transmembrane conductance regulator modulator-naive children with CF (median age, 9.4 [3.4-13.2] yr; range, 0-18 yr) underwent same-session chest and paranasal sinus MRI as well as spirometry (to determine forced expiratory volume in 1 s percent predicted) and multiple-breath washout (to determine lung clearance index z-score). Pulmonary and paranasal sinus abnormalities were assessed using previously validated chest MRI and CRS-MRI scoring systems. Results: Mean chest MRI global score was similar in children with PCD and CF (15.0 [13.5-20.8] vs. 15.0 [9.0-15.0]; P = 0.601). Consolidations were more prevalent and severe in children with PCD (56% vs. 25% and 1.0 [0.0-2.8] vs. 0.0 [0.0-0.3], respectively; P < 0.05). The chest MRI global score correlated moderately with forced expiratory volume in 1 second percent predicted in children with PCD and children with CF (r = -0.523 and -0.687; P < 0.01) and with lung clearance index in children with CF (r = 0.650; P < 0.001) but not in PCD (r = 0.353; P = 0.196). CRS-MRI sum score and mucopyocele subscore were lower in children with PCD than in children with CF (27.5 [26.3-32.0] vs. 37.0 [37.8-40.0] and 2.0 [0.0-2.0] vs. 7.5 [4.8-9.0], respectively; P < 0.01). CRS-MRI sum score did not correlate with chest MRI score in PCD (r = 0.075-0.157; P = 0.557-0.788) but correlated moderately with MRI morphology score in CF (r = 0.437; P < 0.01). Conclusions: MRI detects differences in lung and paranasal sinus abnormalities between children with PCD and those with CF. Lung disease does not correlate with CRS in PCD but correlates in CF.

Impact of Psychiatric Symptoms on Nasal Perception in Septorhinoplasty Patients.

Psychological assessment plays a crucial role in the preoperative phase of septorhinoplasty (SRPL), exerting potential influence on both pre- and postoperative aspects of quality of life (QoL). In this prospective study, SRPL patients were systematically screened using two validated questionnaires for body dysmorphic disorder (BDD) and one each for anxiety, depression, and somatic symptom disorder (SSD). Nasal perception was evaluated utilizing two disease-specific, self-report instruments: The Rhinoplasty Outcomes Evaluation (ROE) and the Functional Rhinoplasty Outcome Inventory-17 (FROI-17). A total of 95 patients were enrolled. Positive screening rates were 40.4 and 28.3% for BDD, 37.3% for elevated anxiety, 16.4% for depression, and 22.4% for SSD. Mean scores on the ROE and FROI indicated lower QoL in all positive screening groups. Statistically significant differences were observed for anxiety (FROI total score: 47.1 ± 14.6 to 37.8 ± 16.2; p = 0.021) and BDD (ROE: 43.7 ± 15.7 to 32.5 ± 15.5; p = 0.003 and FROI total score: 47.4 ± 15.3 to 37.8 ± 17.1; p = 0.014). The Hospital Anxiety and Depression Scale exhibited a significant correlation with the preoperative FROI score (r = 0.34, p = 0.005). Patients with positive screenings for depression, anxiety, BDD, and SSD demonstrated compromised QoL during preoperative assessments compared with their negative counterparts, reflecting diminished nasal perception in both esthetic and functional dimensions. Surgeons must be cognizant of these psychological aspects during preoperative evaluations.

[Choanal atresia repair in Germany : Resection of dorsal septal parts and stents in focus]. / Versorgung von Choanalatresien in Deutschland : Dorsale Septumresektion und Stents im Fokus.

BACKGROUND: Various surgical techniques using transpalatinal, transseptal, and transnasal approaches for surgical repair of choanal atresia have been developed over the past 200 years. Endoscopic endonasal surgery with resection of dorsal septal parts and without the use of stents is the current scientific trend, as high success rates with low complication rates can be achieved. This study examined whether this technique has actually become standard in Germany, and also investigates the role played by stents. METHODS: A total of 52 ear, nose, and throat (ENT) hospitals in Germany, including all 39 university ENT hospitals and 13 non-university maximum-care ENT hospitals, were asked which surgical technique they use for choanal atresia repair and whether stents are used. RESULTS: For dorsal septal resection, 39 of 44 responding hospitals (89%) indicated that they resect dorsal septal parts, 85% of the university hospitals and 100% of the non-university hospitals. For use of stents, 20 of 48 responding hospitals (42%) reported not using stents, whereas 39% of the university hospitals and 50% of the non-university hospitals do use them. CONCLUSION: Endoscopic endonasal choanal atresia repair with resection of dorsal septal parts is, in most instances, used as the standard technique in large ENT hospitals in Germany. Routine use of stents is still widespread. The future aim should be to reduce the use of stents in the treatment of choanal atresia and to use this method only in difficult, individual cases.

Orbital complications of sinusitis in children - Retrospective analysis of an 8.5 year experience.

OBJECTIVE: Orbital complications account for approximately 74-85 % of all complications of acute sinusitis, affect the pediatric population more frequently, and can have devastating consequences. In the years following the COVID-19 pandemic (2022, 2023), a high number of children presented to our clinic with orbital complications. 1)Has there been an increase in orbital complications in the post-covid era? 2)To what extent has the use of MRI reduced radiation in pediatric patients? DESIGN: In our retrospective data analysis, all pediatric patients (age 0-16 years) treated at a university ENT clinic during the period 01/2014-06/2023 who presented with an orbital complication of rhinosinusitis were included. The analysis was descriptive. RESULTS: Forty-four children with orbital complications of rhinosinusitis were treated during the study period, 14 females and 30 males. Most patients (n = 23, 52 %) presented during the years of the waning Covid-19 pandemic (01/2022 to 06/2023). MRI was the initial imaging modality (n = 22,50 %); CT was performed in 17 of 44 cases (39 %) when surgery was indicated. The most common germ detected was of the Streptococcus species, and the predominant antibiotic administered was amipicillin/sulbactam. CONCLUSION: The standard operating procedure (SOP) established at our hospital in 2014 was followed in 42/44 cases. Except for 2 cases, CT was performed exclusively when surgery was indicated. Imaging-related radiation could be avoided in 27 patients (61 %). There was a 30 % increase in orbital complications related to sinus infections postpandemically.

Elexacaftor/tezacaftor/ivacaftor improves chronic rhinosinusitis detected by magnetic resonance imaging in children with cystic fibrosis on long-term therapy with lumacaftor/ivacaftor.

INTRODUCTION: Previous studies using magnetic resonance imaging (MRI) demonstrated early onset and progression of chronic rhinosinusitis (CRS) from infancy to school age, and response to lumacaftor/ivacaftor (LUM/IVA) therapy in children with cystic fibrosis (CF). However, the effect of elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) on CRS detected by MRI in children with CF and at least one F508del mutation, and potential incremental effects of ELX/TEZ/IVA compared to LUM/IVA in F508del homozygous children have not been studied. METHODS: 30 children with CF with at least one F508del mutation underwent three longitudinal paranasal sinus MRI before (MRI1), without (n = 16) or with LUM/IVA therapy (n = 14, MRI2), and with ELX/TEZ/IVA therapy (MRI3, mean age at therapy initiation 11.1 ± 3.4y, range 6-16y). MRI were evaluated using the CRS-MRI score. RESULTS: After therapy initiation with ELX/TEZ/IVA, the prevalence and in maxillary and sphenoid sinuses the dominance of mucopyoceles decreased (35% vs. 0 %, p<0.001 and 26% vs. 8 %, p < 0.05, respectively). This leads to a reduction in mucopyocele subscore (-3.4 ± 1.9, p < 0.001), and sinus subscores in MRI3 (maxillary sinus: -5.3 ± 3.1, p < 0.001, frontal sinus: -1.0 ± 1.9, p < 0.01, sphenoid subscore: -2.8 ± 3.5, p < 0.001, ethmoid sinus: -1.7 ± 1.9, p < 0.001). The CRS-MRI sum score decreased after therapy initiation with ELX/TEZ/IVA by -9.6 ± 5.5 score points (p < 0.001). The strength in reduction of mucopyoceles subscore and CRS-MRI sum score was independent of a pretreatment with LUM/IVA from MRI1-MRI2 (p = 0.275-0.999). CONCLUSIONS: ELX/TEZ/IVA therapy leads to improvement of CRS in eligible children with CF. Our data support the role of MRI for comprehensive monitoring of CRS disease severity and response to therapy in children with CF.

[Fundamentals and practice of the application of nasal packing in sinonasal surgery]. / Grundlagen und Praxis der Anwendung von Nasentamponaden in der endonasalen Chirurgie.

BACKGROUND AND OBJECTIVES: This paper presents an overview on nasal packing materials which are available in Germany. The current literature is analyzed whether there are robust criteria regarding use nasal packing after sinonasal surgery, whether there are fundamental and proven advantages or disadvantages of products, and what this means in clinical practice. MATERIALS AND METHODS: Selective literature analysis using the PubMed database (key words "nasal packing", "nasal tamponade", "nasal surgery", "sinonasal surgery", or "sinus surgery"), corresponding text books and resulting secondary literature. RESULTS AND CONCLUSIONS: Because of systematic methodological shortcomings, the literature does not help in the decision-making about which nasal packing should be used after which kind of sinonasal surgery. In fact, individual approaches for the many different clinical scenarios are recommended. In principle, nasal packing aims in hemostasis, should promote wound healing, and should not result in secondary morbidity. Nasal packing materials should be smooth (non-absorbable materials), inert (absorbable materials), and should not exert excessive pressure. Using non-absorbable packing entails the risk of potentially lethal aspiration and ingestion. For safety reasons inpatient control is recommended as long as this packing is in situ. With other, uncritical packing materials and in patients with special conditions, outpatient control could be justified.

[Pediatric chronic rhinosinusitis]. / Pädiatrische chronische Rhinosinusitis.

Pediatric chronic rhinosinusitis (PCRS) differs from adult chronic rhinosinusitis (CRS) in several aspects. The confrontation with the environment takes place in the growing sinus system, and the immune system is also developing. The inflammatory mechanisms differ to some extent from those of adult CRS patients. The adenoid vegetations play an important role, particularly during the first 6 years of life. Other pathogenetic aspects are important (e.g., asthma, gastroesophageal reflux disease, immunodeficiency). Genetically determined systemic diseases such as cystic fibrosis cause specific challenges in diagnostics and treatment already in childhood. Consistent conservative therapy is often successful, but surgical procedures that have been proven to be effective and associated with few complications are also increasingly used.

Quality of Life and Screening on Body Dysmorphic Disorder, Depression, Anxiety in Septorhinoplasty.

OBJECTIVES: Septorhinoplasty (SRPL) can improve quality of life (QoL) in functional and aesthetical aspects of the nose. A key factor compromising postoperative satisfaction is symptoms of body dysmorphic disorder (BDD), defined by excessive concerns and distress over slight or imagined physical defects. Although a high prevalence of BDD in SRPL patients is evident, the effect of positive screening on BDD and other psychiatric disorders is understudied. It was hypothesized that patients screening positive for BDD, depression or anxiety do not show increased postoperative QoL. METHODS: A multicenter, prospective study including 259 patients. For psychiatric evaluation, the BDD concern questionnaire-aesthetic version and the Hospital Anxiety and Depression Scale were used; for disease-specific QoL the Rhinoplasty Outcomes Evaluation (ROE) and the Functional Rhinoplasty Outcome Inventory (FROI-17). RESULTS: In preoperative evaluation, 32.5% had a positive screening for BDD, 42.2% for increased anxiety, and 32.9% for depression. Mean QoL improved in the whole cohort (FROI total score: 54.4 ± 21.8 to 32.8 ± 23.7 and ROE: 32.3 ± 15.6 to 69.8 ± 23.1, both p < 0.001). Patients screening positive for BDD, depression or anxiety did show an increased postoperative QoL, but to a significantly lower degree and with lower pre- and postoperative QoL levels. CONCLUSIONS: SRPL patients show a high prevalence of BDD symptoms, elevated anxiety, and depression. These subgroups show lower QoL levels and an impaired QoL increase after surgery. Rhinoplasty surgeons must be aware of the disorders and their symptoms, discuss potential concerns with the patients, and potentially refer them to a specialist. LEVEL OF EVIDENCE: Level 3 Laryngoscope, 2023.

Normative data for interpreting the SNOT-22.

Objectives: The Sino-Nasal Outcome Test 22 (SNOT-22) is a validated patient-reported outcome instrument to evaluate the health-related quality of life (HRQoL) in patients with chronic rhinosinusitis (CRS). There are no published normative SNOT-22 scores, limiting its interpretation. Methods: Symptom scores from 1,000 SNOT-22 questionnaires were analysed by principal component analysis (PCA) and exploratory factor analyses. Data were derived from a survey with 1,000 healthy Europeans (reference cohort) who were recruited using the Respondi panel for market and social science research. This subsample was quoted to the population distribution of the German Microcensus and selected from a non-probability panel. Results: The overall normative SNOT-22 score can be detected to be 20.2 ± 19.44. Male (18.49 ± 19.15) and older (> 50 years old; 18.3 ± 17.49) participants had overall lower SNOT-22 mean results than females (21.8 ± 19.6) and younger (21.4 ± 20.55) participants, indicating higher levels of satisfaction. PCA proposed two SNOT-22 domains ("physiological well-being" and "psychological well-being"), which explained 65% of the variance. Conclusions: These are the first published (German) normative scores for the SNOT-22 and provide a clinical reference point for the interpretation of data.

Long-term effects of lumacaftor/ivacaftor on paranasal sinus abnormalities in children with cystic fibrosis detected with magnetic resonance imaging.

Introduction: Chronic rhinosinusitis (CRS) usually presents with nasal congestion, rhinorrhea and anosmia impacts quality of life in cystic fibrosis (CF). Especially mucopyoceles pathognomonic for CRS in CF may cause complications such as spread of infection. Previous studies using magnetic resonance imaging (MRI) demonstrated early onset and progression of CRS from infancy to school age in patients with CF, and mid-term improvements of CRS in preschool and school-age children with CF treated with lumacaftor/ivacaftor for at least 2 months. However, long-term data on treatment effects on paranasal sinus abnomalities in preschool and school-age children with CF are lacking. Methods: 39 children with CF homozygous for F508del (mean age at baseline MRI 5.9 ± 3.0 years, range 1-12 years) underwent MRI before (MRI1) and about 7 months after starting lumacaftor/ivacaftor and then annually (median 3 follow-up MRI, range 1-4) (MRI2-4). MRI were evaluated using the previously evaluated CRS-MRI score with excellent inter-reader agreement. For intraindividual analysis ANOVA mixed-effects analysis including Geisser-Greenhouse correction and Fisher's exact test, and for interindividual group analysis Mann-Whitney test were used. Results: The CRS-MRI sum score at baseline was similar in children starting lumacaftor/ivacaftor in school age and children starting therapy at preschool age (34.6 ± 5.2 vs.32.9 ± 7.8, p = 0.847). Mucopyoceles were the dominant abnormality in both, especially in maxillary sinus (65% and 55%, respectively). In children starting therapy in school age the CRS-MRI sum score decreased longitudinally from MRI1 to MRI2 (-2.1 ± 3.5, p < 0.05), MRI3 (-3.0 ± 3.7, p < 0.01) and MRI4 (-3.6 ± 4.7, p < 0.01), mainly due to a decrease in the mucopyoceles subscore (-1.0 ± 1.5, p = 0.059; -1.2 ± 2.0, p < 0.05; -1.6 ± 1.8, p < 0.01; and -2.6 ± 2.8, p = 0.417, respectively). In children starting lumacaftor/ivacaftor in preschool age, the CRS-MRI sum score remained stable under therapy over all three follow-up MRI (0.6 ± 3.3, p = 0.520; 2.4 ± 7.6, p = 0.994; 2.1 ± 10.5, p > 0.999 and -0.5 ± 0.5, p = 0.740; respectively). Conclusion: Longitudinal paranasal sinus MRI shows improvements in paranasal sinus abnormalities in children with CF starting lumacaftor/ivacaftor therapy at school age. Further, MRI detects a prevention of an increase in paranasal sinus abnormalities in children with CF starting lumacaftor/ivacaftor therapy at preschool age. Our data support the role of MRI for comprehensive non-invasive therapy and disease monitoring of paranasal sinus abnormalities in children with CF.

[Validity of the German Menière's Disease Patient-Oriented Symptom Severity Index]. / Validierung des deutschsprachigen Menière's Disease Patient-Oriented Symptom Severity Index.

BACKGROUND: The MD POSI is a disease-specific questionnaire to determine the health-related quality of life (HRQoL) of patients with Menière's disease (MD). OBJECTIVES: Validity and reliability of the German translation of the MD POSI. MATERIAL AND METHODS: Prospective data analysis of a patient group with vertigo (n = 162), which was treated in the otorhinolaryngology of a University Hospital from 2005-2019. A clinical selection was made according to the new Bárány classification in a "definite" and "probable" Menière's disease. HRQoL was assessed using the German translation of the MD POSI, the Vertigo Symptom Score (VSS) and the Short Form (SF-36). Reliability was measured by Cronbach's α and test-retesting after 12 months and again 2 weeks later. Content and agreement validity were examined. RESULTS: Cronbach α values greater than 0.9 indicated good internal consistency. There was no statistically significant difference from baseline to 12 months, except for the subscore "during the attack". There were significant positive correlations between the VSS overall/VER/AA and the overall index of the MD POSI and negative significant correlations with the SF-36 domains physical functioning, physical role functioning, social functioning, emotional role functioning, mental well-being. There were low SRM (standardized response mean) values below 0.5. CONCLUSIONS: The German translation of the MD POSI is a valid and reliable instrument to evaluate the impact of MD on patients' disease-specific quality of life.

Numerical and Machine Learning Analysis of the Parameters Affecting the Regionally Delivered Nasal Dose of Nano- and Micro-Sized Aerosolized Drugs.

The nasal epithelium is an important target for drug delivery to the nose and secondary organs such as the brain via the olfactory bulb. For both topical and brain delivery, the targeting of specific nasal regions such as the olfactory epithelium (brain) is essential, yet challenging. In this study, a numerical model was developed to predict the regional dose as mass per surface area (for an inhaled mass of 2.5 mg), which is the biologically most relevant dose metric for drug delivery in the respiratory system. The role of aerosol diameter (particle diameter: 1 nm to 30 µm) and inhalation flow rate (4, 15 and 30 L/min) in optimal drug delivery to the vestibule, nasal valve, olfactory and nasopharynx is assessed. To obtain the highest doses in the olfactory region, we suggest aerosols with a diameter of 20 µm and a medium inlet air flow rate of 15 L/min. High deposition on the olfactory epithelium was also observed for nanoparticles below 1 nm, as was high residence time (slow flow rate of 4 L/min), but the very low mass of 1 nm nanoparticles is prohibitive for most therapeutic applications. Moreover, high flow rates (30 L/min) and larger micro-aerosols lead to highest doses in the vestibule and nasal valve regions. On the other hand, the highest drug doses in the nasopharynx are observed for nano-aerosol (1 nm) and fine microparticles (1-20 µm) with a relatively weak dependence on flow rate. Furthermore, using the 45 different inhalation scenarios generated by numerical models, different machine learning models with five-fold cross-validation are trained to predict the delivered dose and avoid partial differential equation solvers for future predictions. Random forest and gradient boosting models resulted in R2 scores of 0.89 and 0.96, respectively. The aerosol diameter and region of interest are the most important features affecting delivered dose, with an approximate importance of 42% and 47%, respectively.

[The complex pediatric middle ear hemangioma]. / Das komplizierte kindliche Mittelohrhämangiom.

Hemangiomas in the pediatric middle ear are a rare occurrence. We present the case of a 3-year-old boy with unilateral hearing impairment and recurrent otitis media with effusion due to a hemangioma in the middle ear. This caused a venous sinus thrombosis, osteomyelitis, and mastoiditis. Interdisciplinary treatment was performed. This case shows that even benign lesions in the middle ear can cause severe, life-threatening complications due to the close proximity of important anatomic structures in the middle ear. Every case of asymmetric hearing loss should thus be examined in detail.

Does a tonsillectomy indicated according to the German S2k guideline affect short-term quality of life in adults?

BACKGROUND: Tonsillectomy (TE) for recurrent tonsillitis (RT) is one of the most common surgical interventions. Since 2015, the indication criteria for TE have become much stricter (German S2k guideline). Patient-reported outcome measures (PROMs) of short-term quality of life (QoL) after TE have not yet been investigated. PURPOSE: To clarify if stringent indication for TE will better identify patients worthy of surgery and patients' QoL. METHODS: We prospectively studied the Tonsillectomy Outcome Inventory 14 (TOI-14) responses of 38 RT-patients recruited according to the S2k guideline in 2020 and compared their TOI-14 scores with those of a historical RT cohort from 2006 to 2008 and with a healthy middle-European cohort. New RT patients were assessed before, 2, 4, and 14 days and 6 months after TE. TOI-14 was measured as total and as disease-specific score. RESULTS: From pre- to 6-month postoperative, patients' QoL was significantly different, measured by TOI-14 (49.92 vs. 6.35; p < 0.001) and disease-specific score (60.35 vs. 9.9; p < 0.001). Preoperative disease-specific score was not different from that of the 2nd and 4th postoperative days but from the 14th postoperative day (60.35 vs. 29.26; p < 0.001). The historical cohort had significantly less RT complaints than the new cohort beforehand, but more dissatisfaction in QoL after TE. New TE patients had worse QoL pre- (49.92 vs. 11.78; p < 0.001) but more QoL postoperatively (6.34 vs. 11.78; p = 0.004) than healthy individuals. CONCLUSIONS: Our results show that the tightening of the indication criteria for TE was justified and that TE patients significantly benefit from this surgery from day 14.

Longitudinal Magnetic Resonance Imaging Detects Onset and Progression of Chronic Rhinosinusitis from Infancy to School Age in Cystic Fibrosis.

Rationale: Chronic rhinosinusitis (CRS) contributes to morbidity in patients with cystic fibrosis (CF). However, longitudinal data on CRS onset and progression is lacking. Objectives: To longitudinally evaluate CRS in CF from infancy to school age with paranasal sinus magnetic resonance imaging (MRI). Methods: A total of 64 children with CF (mean age at baseline, 1.1 ± 1.6 yr; range, 0-5 yr) underwent a mean of 5.8 ± 2.2 (range, 3-11 yr) subsequent annual MRI examinations. Additional 24 children (9.2 ± 4.4 yr; range, 3-17 yr) homozygous for the F508del mutation underwent MRI before and at least 2 months after starting lumacaftor/ivacaftor. MRI was assessed using the previously evaluated CRS-MRI score. Results: In infancy, 65-87% of paranasal sinuses were opacified, and mucosal swelling was the dominant abnormality (58-97%). At preschool age (1-5 yr), 79-94% of sinuses were opacified (P < 0.05 vs. infancy), and mucosal swelling was the most dominant abnormality (79-94%; P < 0.05). At school age (at least 6 yr), almost all sinuses were opacified (71-99%; P < 0.001-0.357 vs. preschool age), and mucopyoceles were the dominant abnormality in maxillary and frontal sinuses (53-56%; P < 0.05-0.808). The CRS-MRI sum score increased from 22.4 ± 9.6 in infancy to 34.2 ± 9.6 in preschool age (P < 0.001) and was 34.0 ± 5.7 in school age (P = 0.052). In children under lumacaftor/ivacaftor therapy, the CRS-MRI sum score (-0.5 ± 3.3; P < 0.05) and maxillary sinus subscore (-0.5 ± 1.5; P < 0.05) improved. Conclusions: Longitudinal paranasal sinus MRI detects an early onset and progression of the severity of CRS from infancy to school age, and response to lumacaftor/ivacaftor therapy in children with CF. Our data support its role in the comprehensive noninvasive monitoring of CRS in children with CF. Clinical trial registered with www.clinicaltrials.gov (NCT02270476).

Does a closed reduction improve aesthetical and functional outcome after nasal fracture?

BACKGROUND AND PURPOSES: How closed reduction (CR) to repair a nasal fracture affects the patient's quality of life (QoL) has not been investigated. Here, we assessed QoL before and after CR using disease-specific questionnaires and compared the QoL scores of patients with nasal fractures with normative scores from a reference cohort. METHODS: This was a prospective study of 96 patients with nasal fractures undergoing CR. Patients were interviewed about aesthetic, functional, and QoL issues before and after surgery using the Functional Rhinoplasty Outcome Inventory (FROI-17) and the Rhinoplasty Outcome Evaluation (ROE). Photographs of the nasal area were taken before and after surgery and reviewed. Data were compared with those from a reference cohort (n = 1000). RESULTS: Most fractures were type I (80.6%) and most were caused by sport-related accidents (36.5%). The ROE scores increased from 67.3 preoperatively to 73.4 postoperatively (p = 0.001). The FROI-17 also improved, indicating the overall effect of the nose on QoL (p = 0.002). Compared with the reference cohort, patients felt more affected by nasal symptoms before surgery (- 9.37, p = 0.02) than by more general aspects. ROE scores returned to normative values after surgery (p < 0.001). The postoperative cohort had lower scores for the FROI-17 item overall effects of the nose on QoL than the reference cohort did, although the nasal symptom score remained higher in patients than in reference controls. CONCLUSIONS: This study showed that CR can improve the aesthetical but not the functional outcome of the nose.

[Statement on hospitalization of children after otorhinolaryngologic interventions in Germany : Position paper from the Pediatric Otorhinolaryngology Working Group of the German Society of Otorhinolaryngology, Head and Neck Surgery]. / Stellungnahme zur Hospitalisierung von Kindern anlässlich von HNO-Eingriffen in Deutschland : Positionspapier der Arbeitsgemeinschaft Pädiatrische HNO-Heilkunde der Deutschen Gesellschaft für Hals-Nasen-Ohren-Heilkunde, Kopf- und Hals-Chirurgie.

The inpatient care of children after ENT surgery is organized heterogeneously across Germany. In this statement, the working group on Pediatric ENT comments a national survey on the status quo of child care after ENT interventions in German hospitals. The statement should serve as a basis for further interdisciplinary discussion.
