Background Current treatment paradigms recommend surgical intervention when conventional medical management proves ineffective in resolving chronic rhinosinusitis with nasal polyposis. Objectives To assess and compare the efficacy of dupilumab and functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis with nasal polyp (CRSwNP) over time. Methods Studies comparing CRSwNP patients who received dupilumab with those who underwent FESS were included. Outcome measures included the nasal congestion score (NCS), Sino-nasal Outcome Test-22 (SNOT-22), University of Pennsylvania Smell Identification Test-40 (UPSIT-40), and nasal polyp score (NPS). The risk of bias was evaluated using the Newcastle-Ottawa Scale. Results A total of 4 studies with 724 participants were included. The dupilumab group had a superior NCS, but an inferior NPS, compared to the FESS group during the follow-up period. The SNOT-22 score of the dupilumab group was inferior to that of the FESS group until 6 months posttreatment, but the scores were similar at around 1 year. A similar trend was observed for the UPSIT-40 score, but the score of the dupilumab group was higher at around 1 year. Conclusion Functional endoscopic sinus surgery was more effective than dupilumab for several months after treatment. However, at 1 year after treatment, the effects of the 2 treatments became similar, with greater olfactory improvement seen in the dupilumab group.

Objectives The primary aim of this study was to assess disparities in nasal nitric oxide (NO) levels between individuals diagnosed with eosinophilic chronic rhinosinusitis (ECRS) and those without ECRS. The second aim was to ascertain the comparative predictive efficacy of these nasal NO levels for the presence of ECRS. Methods A systematic analysis was conducted on relevant studies that compared nasal NO levels in individuals with ECRS and those without. Furthermore, the discriminatory capacity of nasal NO in distinguishing ECRS from non-ECRS cohorts was quantified. The risk of bias across studies was evaluated utilizing the Newcastle-Ottawa scale. Results The comprehensive review encompassed a total of 5 studies involving 470 participants. Findings revealed that patients diagnosed with ECRS exhibited significantly higher levels of nasal NO, as measured in parts per billion (ppb), compared to their non-ECRS patients. The mean difference was 130.03 ppb (95% confidence interval: [66.30, 193.75], I2 = 58.7%). The diagnostic odds ratio for nasal NO in identifying ECRS was 9.29 ([5.85, 14.75], I2 = 26.4%). The area under the summary receiver operating characteristic curve was 0.82. The correlation between sensitivity and false positive rate was 0.53, suggesting a lack of heterogeneity. Sensitivity, specificity, negative predictive value, and positive predictive value were 69% ([0.55, 0.79], I2 = 77.0%), 83% ([0.73, 0.90], I 2 = 68.5%), 77% ([0.69, 0.83], I 2 = 50.1%), and 75% ([0.67, 0.82], I 2 = 41.5%), respectively. Conclusion Nasal NO has the potential as a noninvasive diagnostic measure and endotype tool for ECRS.

AbstractBackgroundWe investigated the role of perioperative intraoral glossopharyngeal nerve block to minimize postoperative pain in patients undergoing tonsillectomy through a meta‐analysis of the relevant literature.MethodsWe retrieved eight studies from PubMed, Scopus, Embase, Web of Science, and Cochrane databases up to August 2023. We compared perioperative glossopharyngeal nerve block with a control group, in order to examine postoperative pain, analgesic use, and other postoperative morbidities.ResultsPostoperative pain was significantly reduced at 1–4 h (SMD −1.26, 95% CI [−2.35; −0.17], I2 = 94.7%, P = 0.02) and 5–8 hours (SMD −1.40, 95% CI [−2.47; −0.34], I2 = 96.1%, p = 0.01) in the treatment groups compared to the control group. However, glossopharyngeal nerve block showed no efficacy in reducing pain or use of analgesic drugs after 12 h compared to the control group. The incidences of postoperative bleeding (OR 0.95, 95% CI [0.35; 2.52], I2 = 0.0%), local agent toxicity (OR 4.14, 95% CI [0.44; 38.63], I2 = 0.0%), nasal problems (OR 1.25, 95% CI [0.60; 2.61], I2 = 0.0%), postoperative nausea and vomiting (OR 1.35, 95% CI [0.78; 2.33], I2 = 0.0%), swallowing difficulty (OR 1.61, 95% CI [0.76; 3.42], I2 = 56.0%), and voice change (OR 3.11, 95% CI [0.31; 30.80], I2 = 0.0%) were not significantly different between the treatment and control groups. The treatment group showed higher prevalence of respiratory problems and dry mouth compared to control without statistical significance, but a significant increase in throat discomfort (p = 0.02).ConclusionIntraoral glossopharyngeal nerve block for tonsillectomy did not significantly impact postoperative pain management and was associated with some adverse effects with increases in respiratory problems, dry mouth, and throat discomfort compared to controls.

Background: To compare conventional smears (CSs) and liquid-based preparations (LBPs) for diagnosing thyroid malignant or suspicious lesions. Methods: Studies in the PubMed, SCOPUS, Embase, Web of Science, and Cochrane database published up to December 2023. We reviewed 17 studies, including 15,861 samples. Results: The diagnostic odds ratio (DOR) for CS was 23.6674. The area under the summary receiver operating characteristic curve (AUC) was 0.879, with sensitivity, specificity, negative predictive value, and positive predictive value of 0.8266, 0.8668, 0.8969, and 0.7841, respectively. The rate of inadequate specimens was 0.1280. For LBP, the DOR was 25.3587, with an AUC of 0.865. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.8190, 0.8833, 0.8515, and 0.8562. The rate of inadequate specimens was 0.1729. For CS plus LBP, the AUC was 0.813, with a lower DOR of 9.4557 compared to individual methods. Diagnostic accuracy did not significantly differ among CS, LBP, and CS plus LBP. Subgroup analysis was used to compare ThinPrep and SurePath. The DORs were 29.1494 and 19.7734. SurePath had a significantly higher AUC. Conclusions: There was no significant difference in diagnostic accuracy or proportion of inadequate smears between CS and LBP. SurePath demonstrated higher diagnostic accuracy than ThinPrep. Recommendations for fine-needle aspiration cytology should consider cost, feasibility, and accuracy.

This study investigated the influence of hypoxic culture conditions on human nasal inferior turbinate-derived stem cells (hNTSCs), a subtype of mesenchymal stem cells (MSCs). It aimed to discern how hypoxia affected hNTSC characteristics, proliferation, and differentiation potential compared to hNTSCs cultured under normal oxygen levels. After obtaining hNTSCs from five patients, the samples were divided into hypoxic and normoxic groups. The investigation utilized fluorescence-activated cell sorting (FACS) for surface marker analysis, cell counting kit-8 assays for proliferation assessment, and multiplex immunoassays for cytokine secretion study. Differentiation potential—osteogenic, chondrogenic, and adipogenic—was evaluated via histological examination and gene expression analysis. Results indicated that hNTSCs under hypoxic conditions preserved their characteristic MSC phenotype, as confirmed by FACS analysis demonstrating the absence of hematopoietic markers and presence of MSC markers. Proliferation of hNTSCs remained unaffected by hypoxia. Cytokine expression showed similarity between hypoxic and normoxic groups throughout cultivation. Nevertheless, hypoxic conditions reduced the osteogenic and promoted adipogenic differentiation potential, while chondrogenic differentiation was relatively unchanged. These insights contribute to understanding hNTSC behavior in hypoxic environments, advancing the development of protocols for stem cell therapies and tissue engineering.

Background and Objectives: Through a comprehensive meta-analysis of the pertinent literature, this study evaluated the utility and efficacy of perioperative infraorbital and/or infratrochlear nerve blocks in reducing postoperative pain and related morbidities in patients undergoing septorhinoplasty. Materials and Methods: We reviewed studies retrieved from the PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases up to August 2023. The analysis included a selection of seven articles that compared a treatment group receiving perioperative infraorbital and/or infratrochlear nerve blocks with a control group that either received a placebo or no treatment. The evaluated outcomes covered parameters such as postoperative pain, the amount and frequency of analgesic medication administration, the incidence of postoperative nausea and vomiting, as well as the manifestation of emergence agitation. Results: The treatment group displayed a significant reduction in postoperative pain (mean difference = −1.7236 [−2.6825; −0.7646], I2 = 98.8%), as well as a significant decrease in both the amount (standardized mean difference = −2.4629 [−3.8042; −1.1216], I2 = 93.0%) and frequency (odds ratio = 0.3584 [0.1383; 0.9287], I2 = 59.7%) of analgesic medication use compared to the control. The incidence of emergence agitation (odds ratio = 0.2040 [0.0907; 0.4590], I2 = 0.0%) was notably lower in the treatment group. The incidence of postoperative nausea and vomiting (odds ratio = 0.5393 [0.1309; 2.2218], I2 = 60.4%) showed a trend towards reduction, although it was not statistically significant. While no adverse effects reaching statistical significance were reported in the analyzed studies, hematoma (proportional rate = 0.2133 [0.0905; 0.4250], I2 = 76.9%) and edema (proportional rate = 0.1935 [0.1048; 0.3296], I2 = 57.2%) after blocks appeared at rates of approximately 20%. Conclusions: Infraorbital and/or infratrochlear nerve blocks for septorhinoplasty effectively reduce postoperative pain and emergence agitation without notable adverse outcomes.

AbstractObjectiveInternal nasal valve dysfunction is a prevalent cause of nasal obstruction. This systematic review, along with a Meta‐analysis, evaluated the efficacy of temperature‐controlled radiofrequency device (RFD) treatment in alleviating nasal obstruction by rectifying nasal valve collapse.Data SourcesA comprehensive review of studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases (up to December 2022) was conducted.Review MethodsWe included studies that evaluated the quality of life and nasal obstruction scores before and after RFD treatment. In addition, sham‐controlled studies were analyzed.ResultsIn total, 451 patients across 8 studies were included in the analysis. Patients who underwent RFD treatment reported a significantly enhanced quality of life 24 months after treatment compared to pretreatment scores. The rates of clinically improved states and positive responses regarding quality of life after treatment were 82% and 91%, respectively. Moreover, the disease‐specific quality of life, as assessed by the Nasal Obstruction Symptom Evaluation score, significantly improved.ConclusionRFD may help improve nasal obstruction symptoms. Further randomized clinical studies on larger cohorts are essential to substantiate its efficacy in enhancing nasal valve function.

Background: To evaluate the diagnostic performance of ultrasound risk-stratification systems for the discrimination of benign and malignant thyroid nodules and to determine the optimal cutoff values of individual risk-stratification systems. Methods: PubMed, Embase, SCOPUS, Web of Science, and Cochrane library databases were searched up to August 2022. Sensitivity and specificity data were collected along with the characteristics of each study related to ultrasound risk stratification systems. Results: Sixty-seven studies involving 76,512 thyroid nodules were included in this research. The sensitivity, specificity, diagnostic odds ratios, and area under the curves by K-TIRADS (4), ACR-TIRADS (TR5), ATA (high suspicion), EU-TIRADS (5), and Kwak-TIRADS (4b) for malignancy risk stratification of thyroid nodules were 92.5%, 63.5%, 69.8%, 70.6%, and 95.8%, respectively; 62.8%, 89.6%, 87.2%, 83.9%, and 63.8%, respectively; 20.7111, 16.8442, 15.7398, 12.2986, and 38.0578, respectively; and 0.792, 0.882, 0.859, 0.843, and 0.929, respectively. Conclusion: All ultrasound-based risk-stratification systems had good diagnostic performance. Although this study determined the best cutoff values in individual risk-stratification systems based on statistical assessment, clinicians could adjust or alter cutoff values based on the clinical purpose of the ultrasound and the reciprocal changes in sensitivity and specificity.

(1) Background: To determine the optimal cut-off values of two risk stratification systems to discriminate malignant thyroid nodules and to compare the diagnostic performance; (2) Methods: True and false positive and negative data were collected, and methodological quality was assessed for forty-six studies involving 39,085 patients; (3) Results: The highest area under the receiver operating characteristic (ROC) curve (AUC) of ACR and Kwak TI-RADS were 0.875 and 0.884. Based on the optimal sensitivity and specificity, the highest accuracy values of ROC curves or diagnostic odds ratios (DOR) were taken as the cut-off values for TR4 (moderate suspicious) and 4B. The sensitivity, specificity, DOR, and AUC by ACR (TR4) and Kwak TI-RADS (4B) for malignancy risk stratification of thyroid nodules were 94.3% and 96.4%; 52.2% and 53.7%; 17.5185 and 31.8051; 0.786 and 0.884, respectively. There were no significant differences in diagnostic accuracy in any of the direction comparisons of the two systems; (4) Conclusions: ACR and Kwak TI-RADS had good diagnostic performances (AUCs > 85%). Although we determined the best cut-off values in individual risk stratification systems based on statistical assessment, clinicians can adjust the optimal cut-off value according to the clinical purpose of the ultrasonography because raising or lowering cut-points leads to reciprocal changes in sensitivity and specificity.

Background: To assess the safety and effectiveness of transoral robotic thyroidectomy (TORT) in thyroid tumor. Methods: PubMed, Embase, Web of Science, SCOPUS, Cochrane database, and Google Scholar up to June 2022. Studies comparing outcomes and complications between TORT and control groups (robotic bilateral axillo-breast, trans-axillary, postauricular approach, conventional open thyroidectomy (OT), and transoral endoscopic approach) were analyzed. Results: Ten studies of 1420 individuals. The operative time (SMD 1.15, 95%CI [0.48; 1.89]) was significantly longer and the number of retrieved lymph nodes (LNs) (SMD −0.27, 95%CI [−0.39; −0.16]) was fewer in TORT than in the control group. The postoperative cosmetic satisfaction score (SMD 0.60, 95%CI [0.28; 0.92]) was statistically higher in TORT than in the control group. In subgroup analysis, there was no significant difference between robotic surgeries. However, TORT had significantly longer operative times (SMD 2.08, 95%CI [0.95; 3.20]) and fewer retrieved LNs (SMD −0.32, 95%CI [−0.46; −0.17]) than OT. TORT satisfied significantly more patients in cosmetic view. However, it increased hospitalization days and postoperative pain on the operation day and first day compared to OT. Conclusions: TORT is not inferior to other robotic-assisted approaches. Its operation time and hospitalization days are longer and postoperative pain is greater than OT, although its cosmetic satisfaction is high.
