RESUMEN
Maternal cigarette use is associated with the fetal development of orofacial clefts. Air pollution should be investigated for similar causation. We hypothesize that the incidence of non-syndromic cleft lip with or without palate (NSCLP) and non-syndromic cleft palate (NSCP) would be positively correlated with air pollution concentration. METHODS: The incidence of NSCLP and NSCP per 1000 live births from 2016 to 2020 was extracted from the Centers for Disease Control and Prevention Vital Statistics Database and merged with national reports on air pollution using the Environmental Protection Agency Air Quality Systems annual data. The most commonly reported pollutants were analyzed including benzene, sulfur dioxide (SO2), particulate matter (PM) 2.5, PM 10, ozone (O3), and carbon monoxide (CO). Multivariable negative binomial and Poisson log-linear regression models evaluated the incidence of NSCLP and NSCP as a function of the pollutants, adjusting for race. All p-values are reported with Bonferroni correction. RESULTS: The median NSCLP incidence was 0.22/1000 births, and isolated NSCP incidence was 0.18/1000 births. For NSCLP, SO2 had a coefficient estimate (CE) of 0.60 (95% CI [0.23, 0.98], p < 0.007) and PM 2.5 had a CE of 0.20 (95% CI [0.10, 0.31], p < 0.005). Among isolated NSCP, no pollutants were found to be significantly associated. CONCLUSION: SO2 and PM 2.5 were significantly correlated with increased incidence of NSCLP. The American people and perinatal practitioners should be aware of the connection to allow for risk reduction and in utero screening.

BACKGROUND: Functional and aesthetic nasal operations are some of the most common plastic surgery procedures performed in the United States. The purpose of the study was to evaluate the effects of septoplasty, septorhinoplasty, and rhinoplasty procedures on postoperative olfactory function and their relationship to nasal airflow and quality of life. METHODS: A systematic review and meta-analysis was performed evaluating olfactory function following nasal surgery. Preoperative and postoperative values for olfaction, nasal airflow, and quality of life/nasal symptoms were analyzed. The effect size was calculated from each study and used for meta-analysis. As studies evaluated patients at different points in the postoperative period, the latest time point reported by each study was used in the meta-analysis. The 95 percent confidence interval of the effect size was calculated for each study. Study quality was assessed using the Jadad and Methodological Index for Nonrandomized Studies instruments. All included studies were Level of Evidence II. RESULTS: There were 25 included studies. Following nasal surgery, patients experienced significant improvements in olfaction (p < 0.001), nasal airflow (p < 0.001), and quality of life/nasal symptoms (p < 0.001). Patients often experienced a transient decrease in olfaction immediately after surgery, followed by improvement postoperatively. Preoperative olfactory dysfunction rates were low and postoperative dysfunction was equally low. Olfaction improvement was directly correlated with improvement in nasal airflow and quality of life. CONCLUSIONS: Functional and aesthetic nasal operations appear to significantly improve olfaction, which is directly correlated with nasal airflow. Some studies report a transient worsening of these measures in the immediate postoperative period, which subsequently improved at later time points.

ABSTRACT: Irradiated cadaveric costal cartilage (CC) has been utilized as an alternative to autologous cartilage (AC) in functional and aesthetic nasal surgery. The impact of graft choice between AC and CC on functional outcomes in rhinoplasty has yet to be studied. A systematic review was performed in PubMed, Embase, and Cochrane databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify comparative studies evaluating the efficacy and safety of CC in nasal surgery. Functional and aesthetic outcomes and complications were reviewed and compared between AC and CC. Meta-analytic comparisons were performed when appropriate using data from comparative studies using a random-effects model. Four studies met inclusion criteria. The indication for surgery was functional in the majority of cases, and 34.6% of cases were revision rhino- or septorhinoplasties. Disparate data across studies prevented meta-analysis on functional outcomes; however, qualitative review of function outcomes demonstrated comparable outcomes between the CC and AC groups. No differences in graft infection, warping, and resorption rates were detected. Analysis of all graft-related complications was higher in the CC group (Pâ=â0.02); however, when AC donor site-related complications were included, no significance between the two groups was observed. In conclusion, limited, high quality data was available for analysis. Of the available studies, this systematic review suggest that the use of AC or CC may lead to comparable results in terms of functional outcomes. More long-term studies directly comparing AC and CC functional outcomes would be welcomed.

BACKGROUND: The choice between internal and external distraction osteogenesis for midface advancement in patients with syndromic craniosynostosis is based primarily on surgeon preference and expertise. However, differences in outcomes between the two techniques have been sparingly compared. In this work, the authors performed a systematic review to compare outcomes between internal versus external midface distraction. METHODS: A systematic review was performed of studies published between 1998 and 2018 (61 studies included; n = 689 patients). Operative characteristics, early reoperations, complications, and relapse rates were extracted. Bias evaluation was performed using the Newcastle-Ottawa instrument. Statistical analyses were performed with independent samples t tests and linear regression analyses (p < 0.05 considered significant). RESULTS: The authors found that external distraction was associated with more Le Fort III osteotomies and hardware adjustments (p = 0.023), whereas internal distraction was associated with more monobloc osteotomies and longer consolidation times (p = 0.008). No significant differences in the distance of midface advancement, reoperations, complications, or relapse rates were noted between internal versus external distraction, although external distraction trended toward a slightly higher relapse rate. Regardless of distraction protocol, consolidation time was found to be a strong negative predictor for relapse (beta = -0.792; p = 0.02). CONCLUSIONS: No significant differences were demonstrated in advancement distance, reoperative rates, complication rates, or relapse rates for internal versus external distraction for midface advancement. Regardless of distraction type, consolidation time was strongly inversely associated with relapse rates. The trend toward higher relapse in external distraction is potentially explained by the significantly lower consolidation times.
