Repair of the Lateral Nasal Wall in Nasal Airway Obstruction: A Systematic Review and Meta-analysis.

ABSTRACT: Importance:While functional rhinoplasty has been broadly studied, to our knowledge no systematic review and meta-analysis of lateral wall repair has been done previously. Objective:To evaluate the effectiveness of repair of the lateral nasal wall in adult patients with nasal airway obstruction. Data Sources:Medline, Embase, Cinahl, Central, Scopus, and Web of Science databases and reference lists were searched for clinical and observational studies. Study Selection:The selection criteria were defined according to the PICO (population, intervention, comparison, and outcome) framework. The relevant studies were selected by 2 independent reviewers based on the studies' abstracts and full texts. Data Extraction and Synthesis:Data were extracted using standardized lists chosen by the authors according to Cochrane Collaboration guidelines. The effect sizes were first calculated for each study and then pooled together using random effects synthesis. Heterogeneity was assessed using the I2 statistic, and publication bias was evaluated by the Egger test. Main Outcomes and Measures:The results were reported as pooled row mean differences in changes from preoperative to postoperative Nasal Obstruction Symptom Evaluation scores at different times of follow-up (≤3 months, >3 to 6 months, and >6 months). Results:Of 1522 initial records, 10 studies were considered relevant-all of them observational. The pooled study sample included 324 participants. When combining all the repeated measures together, the pooled effect size for functional rhinoplasty was -47.7 (95% CI, -53.4 to 42.1) points on the Nasal Obstruction Symptom Evaluation scale with high heterogeneity of 72%. The pooled effect size outcomes were similar in short- (-45.0 points [95% CI, -47.8 to -42.2 points]), mid- (-48.4 points [95% CI, -52.5 to -44.4 points]), and long-term (-49.0 points [95% CI, -62.1 to -35.8 points]) follow-ups. Conclusions and Relevance:The pooled effect size of 10 observational studies supported the effectiveness of functional rhinoplasty for the treatment of nasal airway obstruction caused by lateral nasal wall insufficiency. To improve the level of evidence, randomized clinical trials are needed. Level of Evidence:NA.

Project description:Background: Continuous positive airway pressure (CPAP) has been associated with a lower risk of treatment failure than high-flow nasal cannula (HFNC) in pediatric patients with respiratory distress and severe hypoxemia. However, the publication of new trials on children younger than 2 years warrants a review and updated meta-analysis of the evidence. Methods: We conducted a systematic search in the PubMed, Scopus, and Google scholar databases for randomized controlled trials (RCTs) in pediatric patients with acute respiratory distress that examined outcomes of interest by the two usual management modalities (CPAP and HFNC). We used pooled adjusted relative risks (RRs) to present the strength of association for categorical outcomes and weighted mean differences (WMDs) for continuous outcomes. Results: We included data from six articles in the meta-analysis. The quality of the studies was deemed good. Included studies had infants with either acute viral bronchiolitis or pneumonia. Compared to CPAP, HFNC treatment carried a significantly higher risk of treatment failure [RR, 1.45; 95% CI, 1.06 to 1.99; I 2 = 0.0%, n = 6]. Patients receiving HFNC had a lower risk of adverse events, mainly nasal trauma [RR, 0.30; 95% CI, 0.14 to 0.62; I 2 = 0.0%, n = 2] than the others. The risk of mortality [RR, 3.33; 95% CI, 0.95, 11.67; n = 1] and need for intubation [RR, 1.69; 95% CI, 0.97, 2.94; I 2 = 0.0%, n = 5] were statistically similar between the two management strategies; however, the direction of the pooled effect sizes is indicative of a nearly three times higher mortality and two times higher risk of intubation in those receiving HFNC. We found no statistically significant differences between the two management modalities in terms of modified woods clinical asthma score (M-WCAS; denoting severity of respiratory distress) and hospitalization length (days). Patients receiving HFNC had the time to treatment failure reduced by approximately 3 h [WMD, -3.35; 95% CI, -4.93 to -1.76; I 2 = 0.0%, n = 2] compared to those on CPAP. Conclusions: Among children with respiratory distress younger than 2 years, HFNC appears to be associated with higher risk of treatment failure and possibly, an increased risk of need for intubation and mortality. Adequately powered trials are needed to confirm which management strategy is better.

Project description:BackgroundChildren with severe airway obstruction tend to have a vertical direction of growth, class II malocclusion, and narrow arches. Adenoidectomy and tonsillectomy were recommended for the promotion of balanced dentition growth in these children.The aim of this study was to determine the effect of adenoidectomy and tonsillectomy on the growth of dental morphology in children with airway obstruction.MethodsA comprehensive search of the Medline, Embase, Web of science, and OVID databases for studies published through to January 17, 2016 was conducted. Prospective, comparative, clinical studies assessing the efficacy of adenoidectomy, or tonsillectomy in children with airway obstruction were included. The weighted mean difference (WMD) and 95% confidence interval (CI) were used for continuous variables. Forest plots were drawn to demonstrate effects in the meta-analyses.ResultsEight papers were included in our study. We found that adenoidectomy and tonsillectomy led to a significant change in nasal-breathing in children with airway obstruction. Children with airway obstruction had a significantly narrower posterior maxillary dental arch than children without airway obstruction (WMD = -0.94, 95% CI [-1.13, -0.76]; P < 0.001). After surgery, these children still had a significantly narrower dental arch than the nasal-breathing children (WMD = -0.60, 95% CI [-0.79, -0.42]; P < 0.001). In terms of dental arch width, malocclusion, palatal height, overjet, overbite, dental arch perimeter, and arch length, a tendency toward normalization was evident following adenoidectomy or tonsillectomy, with no significant differences evident between the surgical group and the normal group. The small number of studies and lack of randomized controlled trials were the main limitations of this meta-analysis.ConclusionsFollowing adenoidectomy and tonsillectomy, the malocclusion and narrow arch width of children with airway obstruction could not be completely reversed. Therefore, other treatments such as functional training or orthodontic maxillary widening should be considered after removing the obstruction in the airway.

Project description:Respiratory support is crucial for the survival of preterm infants, and High-flow Nasal Cannula Oxygen Therapy (HFNC) and Continuous Positive Airway Pressure (CPAP) are commonly used for neonatal respiratory support. This meta-analysis aimed to compare the effects of HFNC and CPAP in primary respiratory support for preterm infants, to provide evidence-based support for clinical practice. PubMed, Embase, Cochrane Library, ClinicalTrials.gov, CNKI, VIP, WANFANG and SinoMed were searched for eligible studies. The primary outcomes included the incidence of treatment failure and the application of mechanical ventilation. A total of 27 eligible studies with 3,351 participants were included. There was no significant difference in the incidence of respiratory support failure [RR = 1.17, 95%CI (0.88-1.56)] and the application of mechanical ventilation [RR = 1.00, 95%CI (0.84-1.19)] between HFNC group and CPAP group. HFNC resulted in lower rate of air leaks [RR = 0.65, 95%CI (0.46-0.92)], nasal trauma [RR = 0.36, 95%CI (0.29-0.45)] and abdominal distension [RR = 0.39, 95%CI (0.27-0.58)], and later time of mechanical ventilation initiating [SMD = 0.60, 95%CI (0.21-0.99)], less duration of oxygen therapy [SMD = -0.35, 95%CI (-0.68 to -0.02)] and earlier enteral feeding [SMD = -0.54, 95%CI (-0.95 to -0.13)]. Alternative non-invasive respiratory support after initial treatment failure resulted in no difference in the application of mechanical ventilation between the two groups [RR = 0.99, 95%CI (0.52-1.88)]. HFNC might be more effective and safer in primary respiratory support for preterm infants. Using CPAP as a remedy for the treatment failure of HFNC could not avoid intubation. For premature infants with the gestational age <28 weeks, HFNC as primary respiratory support still needs to be further elucidated.
