Review
PURPOSE
Cleft palate children have a higher incidence of otitis media with effusion, more frequent recurrent acute otitis media episodes, and worse conductive hearing losses than non-cleft children. Nevertheless, data on adenoidectomy for middle ear disease in this patient group are scarce, since many feared worsening of velopharyngeal insufficiency after the procedure. This review aims at collecting the available evidence on this subject, to frame possible further areas of research and interventions.
METHODS
A PRISMA-compliant systematic review was performed. Multiple databases were searched with criteria designed to include all studies focusing on the role of adenoidectomy in treating middle ear disease in cleft palate children. After duplicate removal, abstract and full-text selection, and quality assessment, we reviewed eligible articles for clinical indications and outcomes.
RESULTS
Among 321 unique citations, 3 studies published between 1964 and 1972 (2 case series and a retrospective cohort study) were deemed eligible, with 136 treated patients. The outcomes were positive in all three articles in terms of conductive hearing loss improvement, recurrent otitis media episodes reduction, and effusive otitis media resolution.
CONCLUSION
Despite promising results, research on adenoidectomy in treating middle ear disease in the cleft population has stopped in the mid-Seventies. No data are, therefore, available on the role of modern conservative adenoidectomy techniques (endoscopic and/or partial) in this context. Prospective studies are required to define the role of adenoidectomy in cleft children, most interestingly in specific subgroups such as patients requiring re-tympanostomy, given their known risk of otologic sequelae.

Meta-Analysis Review
This meta-analysis aimed to assess the effectiveness and safety of (adeno)tonsillectomy (AT) for uncomplicated pediatric obstructive sleep apnea (OSA) across different age groups. Four electronic databases were searched until April 2022, and 93 studies (9087 participants) were selected, including before-after studies, cohort studies, and randomized controlled trials. It has been suggested that age, disease severity, and length of follow-up are associated with surgical effects. Compared with older children (>7 years), patients receiving AT surgery before the age of 7 exhibited a significantly greater release of disease severity, as well as a greater decrease in hypoxemic burden, improvement in sleep quality, and better cardiovascular function. Cognitive/behavioral performance also improved after AT, although it was more related to the length of follow-up than the age at surgery. Notably, the surgical complication rate was considerably higher in patients younger than 3 years old. Overall, we suggest that the age of 3-7 years might be optimal for AT in polysomnography-diagnosed uncomplicated OSA to maximize potential benefits for both disease and comorbidities and balance the risks of surgery.

Meta-Analysis
Comparison of the efficacy and safety of conventional curettage adenoidectomy with those of other adenoidectomy surgical techniques: a systematic review and network meta-analysis.
OBJECTIVES
There is a lack of robust evidence in regards to whether the intra and post-operative safety and efficacy of conventional curettage adenoidectomy is better than those of other available surgical techniques. Therefore, this study was conducted as a systematic review and network meta-analysis of published randomized controlled trials (RCTs) with the aim of comparing the safety and efficacy of conventional curettage adenoidectomy with all other available adenoidectomy techniques.
MATERIALS AND METHODS
A systematic search of published articles was performed in 2021 using databases such as PubMed/Medline, EMBASE, EBSCO, and the Cochrane Library. All RCTs that compared conventional curettage adenoidectomy with other surgical techniques and were published in English between 1965 and 2021 were included. The quality of the included RCTs have been assessed using Cochrane Collaboration Risk of Bias Tool.
RESULTS
After screening 1494 articles, 17 were identified for comparing several adenoidectomy techniques and were eligible for quantitative analysis. Of those, 9 RCTs were analyzed for intraoperative blood loss, and 6 articles were included for post-operative bleeding. Furthermore; 14, 10, and 7 studies were included for surgical time, residual adenoid tissue, and postoperative complications respectively. Endoscopic-assisted microdebrider adenoidectomy yielded a statistically significantly greater estimate of intraoperative blood loss compared with conventional curettage adenoidectomy (mean difference [MD], 92.7; 95% confidence interval [CI] 28.3-157.1), suction diathermy (MD, 117.1; 95% CI 37.2-197.1). Suction diathermy had the highest cumulative probability of being the preferred technique because it was estimated to result in the least intraoperative blood loss. Electronic molecular resonance adenoidectomy was estimated to be more likely to result in the shortest surgical time (mean rank, 2.2). Participants in the intervention group were 97% less likely to have residual adenoid tissue than children in the conventional curettage group (odds ratio 0.03; 95% CI 0.01-0.15); therefore, conventional curettage was not considered an appropriate technique for complete removal of adenoid tissue.
CONCLUSION
There is no single technique that can be considered best for all possible outcomes. Therefore, otolaryngologists should make an appropriate choice after critically reviewing the clinical characteristics of children requiring adenoidectomy. Findings of this systematic review and meta-analysis may guide otolaryngologists when making evidence-based decisions regarding the treatment of enlarged and symptomatic adenoids in children.

Review
OBJECTIVE
adenoidectomy is one of the most common surgical procedure in pediatric otolaryngology practice. Clinical guidelines (such as the Spanish or American) suggest adenoidectomy when the enlargement of the adenoids is associated with nasal obstruction. Nasal endoscopy and cephalograms are adequate methods to estimate the size of the adenoids. However, they do not measure nasal patency. This systematic review is designed with the objective of exploring the relationship between adenoid size and nasal ventilation through rhinomanometry.
REVIEW METHODS
3 authors members of the YO-IFOS rhinology study group independently analyzed the data sources (Pubmed, the Cochrane Library, EMBASE, SciELO) for papers assessing both nasal resistance and/or nasal airflow in rhinomanometry and adenoid size by any method (endoscopy, cephalogram, direct examination).
RESULTS
A total of 10 studies with a total population of 969 participants met the inclusion criteria. 5 authors explored the size of the adenoids through endoscopy. 4 authors explored the adenoids through lateral cephalograms. Finally, a further 2 authors explored adenoid size studying the resected tissue. Five studies explored the correlation between adenoid size and nasal resistance in rhinomanometry, which ranged from 0.20 to 0.84. Finally, 5 studies used nasal decongestant. It was found higher sensitivity and specificity, a higher area under the curve for the receiver operating characteristic curve, and higher correlation with adenoid size for rhinomanometry under nasal decongestion.
CONCLUSION
Up to now, there is no ideal diagnostic method for adenoid hypertrophy. Therefore, it seems prudent to use a combination of all currently available tools, as they provide complementary, rather than supplementary information. Available evidence suggests that rhinomanometry combined with nasal decongestant could help to elucidate the existence of nasal obstruction in intermediate cases of adenoid hypertrophy, as well as throw light on other possible causes for nasal obstruction, mainly turbinate hypertrophy.

Review
(1) Background: Supraglottic airway devices (SAD) have been used in children and adolescents undergoing adenotonsillectomies under general anesthesia. This systematic review and meta-analysis investigate the safety and efficacy of using SADs when compared to an endotracheal tube (ETT). (2) Methods: After registering with PROSPERO, databases like PubMed, Scopus, OviD, CINAHL, and Cochrane Library were searched using relevant keywords from the year 2000. We used RoB-2 for risk-of-bias assessment, GRADE for assessing the quality of evidence, RevMan 5.2 for qualitative meta-analysis, and trial sequential analysis (TSA) to corroborate the significant findings of meta-analysis. (3) Results: Out of 200 studies, 5 randomized-controlled trials fulfilled inclusion criteria. The quality of evidence was moderate for laryngospasm, low for airway device failure, and very low for recovery time. The incidence of laryngospasm was comparable between SADs and ETT (RR: 0.80, 95% CI-0.36, 1.80, = 0.59). The incidence of airway device failure was significantly higher with SADs than ETT (RR: 11.29, 95% CI: 2.73, 46.66, = 0.0008). The postoperative recovery time was significantly less with SADs than with ETT use (MD: -4.33, 95% CI: -5.28, -3.39, < 0.0001), which was confirmed by the TSA. (4) Conclusions: The results of this review suggests that use of SADs can provide a lesser postoperative recovery time and comparable incidence of laryngospasm, with a higher incidence of failure of SAD when compared to ETT. Use of SAD for pediatric and adolescent adenotonsillectomies should be individualized based on patient characteristics, and on the expertise of the anesthesiologist and the surgeons involved.

Review
This review investigates the relationship between pediatric obstructive sleep apnea, often associated with adenotonsillar hypertrophy, and cardiovascular health, particularly pulmonary hypertension. We conducted a comprehensive literature search using electronic databases, including Medline Pub-Med, Scopus, and the Web of Science. The study analyzed a total of 230 articles and screened 48 articles, with 20 included in the final analysis, involving 2429 children. The PRISMA flowchart visually illustrates the selection process, and the ROBINS-E and -I tools help ensure the reliability and validity of the evidence produced by these studies. These studies explored various aspects, including the severity of obstructive sleep apnea, cardiac anomalies, cardiac stress markers, risk factors for pulmonary hypertension, and the impact of adenoidectomy and tonsillectomy on cardiac function. The research found that adenotonsillar hypertrophy and obstructive sleep apnea are significant risk factors for cardiovascular complications, especially pulmonary hypertension, in children. Adenoidectomy and tonsillectomy may provide effective treatments. Following adenoidectomy in relation to obstructive sleep apnea, there appears to be a reduction in mean pulmonary artery pressure during echocardiographic examination. However, the efficacy of these procedures can vary based on the severity of obstructive sleep apnea and individual cardiac conditions. The study also identified concerns regarding data bias. The authors emphasize the need for well-designed clinical studies, including both healthy patients with adenotonsillar hypertrophy and vulnerable children with genetic disorders, to ensure that clinical decisions are based on solid scientific evidence.

Review
Grisel's syndrome is an uncommon cervical spine condition marked by non-traumatic rotational subluxation of the atlantoaxial joint. This systematic review aims to collect potential evidence from relevant studies that reported symptoms, diagnostic methods, and management options among pediatric cases of Grisel's syndrome post otolaryngology procedures, which can aid and guide the diagnosis and management in clinical practice. We conducted both electronic and manual search strategies within the potential databases and included case reports, case series, and articles; however, review papers and correspondence papers were excluded. The post-otolaryngology procedures included adenoidectomy, tonsillectomy, tympanoplasty, cochlear implantation, double opposing Z plasty and pharyngeal flap, and adenotonsillectomy. In this systematic review, we identified and analyzed 20 studies encompassing a total of 24 pediatric patients with Grisel's syndrome following otolaryngology procedures. The patient demographics revealed a fairly even distribution between females (45.83%) and males (50.00%), with ages ranging from 2.5 to 12 years. The most common otolaryngology procedures associated with Grisel's syndrome were adenoidectomy (29.17%) and adenotonsillectomy (33.33%). Clinical symptoms included neck pain (75.00%), torticollis (50.00%), and limited neck mobility (20.83%), while diagnostic confirmation primarily relied on CT scans (50.00%). Treatment strategies varied, with conservative measures being the most frequent choice, followed by surgical interventions in four cases (16.67%). Complications were reported in 20.83% of cases. Due to the rarity of this condition, our findings are limited to case reports only, which may limit the generalizability of results. Grisel syndrome can be effectively managed through conservative treatment, including antibiotics and anti-inflammatory drugs if diagnosed timely. Early diagnosis and prompt management are essential to avoid neurological and fatal complications. This analysis would contribute to improving clinical knowledge and treatment strategies while providing additional insights into this rare condition.

Meta-Analysis
BACKGROUND
Sickle cell disease (SCD) is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. SCD can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Surgical interventions are more common in people with SCD, and occur at much younger ages than in the general population. Blood transfusions are frequently used prior to surgery and several regimens are used but there is no consensus over the best method or the necessity of transfusion in specific surgical cases. This is an update of a Cochrane Review.
OBJECTIVES
To determine whether there is evidence that preoperative blood transfusion in people with SCD undergoing elective or emergency surgery reduces mortality and perioperative or sickle cell-related serious adverse events. To compare the effectiveness of different transfusion regimens (aggressive or conservative) if preoperative transfusions are indicated in people with SCD.
SEARCH METHODS
We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 28 January 2020 We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register: 19 September 2019.
SELECTION CRITERIA
All randomised controlled trials and quasi-randomised controlled trials comparing preoperative blood transfusion regimens to different regimens or no transfusion in people with SCD undergoing elective or emergency surgery. There was no restriction by outcomes examined, language or publication status.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed trial eligibility and the risk of bias and extracted data.
MAIN RESULTS
Three trials with 990 participants were eligible for inclusion in the review. There were no ongoing trials identified. These trials were conducted between 1988 and 2011. The majority of people included had haemoglobin (Hb) SS SCD. The majority of surgical procedures were considered low or intermediate risk for developing sickle cell-related complications. Aggressive versus simple red blood cell transfusions One trial (551 participants) compared an aggressive transfusion regimen (decreasing sickle haemoglobin to less than 30%) to a simple transfusion regimen (increasing haemoglobin to 100 g/L). This trial re-randomised participants and therefore quantitative analysis was only possible on two subsets of data: participants undergoing cholecystectomy (230 participants); and participants undergoing tonsillectomy or adenoidectomy surgeries (107 participants). Data were not combined as we do not know if any participant received both surgeries. Overall, the quality of the evidence was very low across different outcomes according to GRADE methodology. This was due to the trial being at high risk of bias primarily due to lack of blinding, indirectness and the outcome estimates being imprecise. Cholecystectomy subgroup results are reported in the abstract. Results for both subgroups were similar. There was no difference in all-cause mortality between people receiving aggressive transfusions and those receiving conservative transfusions. No deaths occurred in either subgroup. There were no differences between the aggressive transfusion group and conservative transfusion group in the number of people developing: • an acute chest syndrome, risk ratio (RR) 0.84 (95% confidence interval (CI) 0.38 to 1.84) (one trial, 230 participants, very low-quality evidence); • vaso-occlusive crisis, risk ratio 0.30 (95% CI 0.09 to 1.04) (one trial, 230 participants, very low quality evidence); • serious infection, risk ratio 1.75 (95% CI 0.59 to 5.18) (one trial, 230 participants, very low-quality evidence); • any perioperative complications, RR 0.75 (95% CI 0.36 to 1.55) (one trial, 230 participants, very low-quality evidence); • a transfusion-related complication, RR 1.85 (95% CI 0.89 to 3.88) (one trial, 230 participants, very low-quality evidence). Preoperative transfusion versus no preoperative transfusion Two trials (434 participants) compared a preoperative transfusion plus standard care to a group receiving standard care. Overall, the quality of the evidence was low to very low across different outcomes according to GRADE methodology. This was due to the trials being at high risk of bias due to lack of blinding, and outcome estimates being imprecise. One trial was stopped early because more people in the no transfusion arm developed an acute chest syndrome. There was no difference in all-cause mortality between people receiving preoperative transfusions and those receiving no preoperative transfusions (two trials, 434 participants, no deaths occurred). There was significant heterogeneity between the two trials in the number of people developing an acute chest syndrome, a meta-analysis was therefore not performed. One trial showed a reduced number of people developing acute chest syndrome between people receiving preoperative transfusions and those receiving no preoperative transfusions, risk ratio 0.11 (95% confidence interval 0.01 to 0.80) (65 participants), whereas the other trial did not, RR 4.81 (95% CI 0.23 to 99.61) (369 participants). There were no differences between the preoperative transfusion groups and the groups without preoperative transfusion in the number of people developing: • a vaso-occlusive crisis, Peto odds ratio (OR) 1.91 (95% confidence interval 0.61 to 6.04) (two trials, 434 participants, very low-quality evidence). • a serious infection, Peto OR 1.29 (95% CI 0.29 to 5.71) (two trials, 434 participants, very low-quality evidence); • any perioperative complications, RR 0.24 (95% CI 0.03 to 2.05) (one trial, 65 participants, low-quality evidence). There was an increase in the number of people developing circulatory overload in those receiving preoperative transfusions compared to those not receiving preoperative transfusions in one of the two trials, and no events were seen in the other trial (no meta-analysis performed).
AUTHORS' CONCLUSIONS
There is insufficient evidence from randomised trials to determine whether conservative preoperative blood transfusion is as effective as aggressive preoperative blood transfusion in preventing sickle-related or surgery-related complications in people with HbSS disease. There is very low quality evidence that preoperative blood transfusion may prevent development of acute chest syndrome. Due to lack of evidence this review cannot comment on management for people with HbSC or HbSβ disease or for those with high baseline haemoglobin concentrations.

Meta-Analysis
BACKGROUND
Adenotonsillectomy is one of the most common surgical procedures worldwide. The current standard for securing the airway in patients undergoing adenotonsillectomy is endotracheal tube (ETT) intubation. Several studies have investigated the use of the laryngeal mask airway (LMA) in this procedure. We conducted a systematic review and meta-analysis to compare the safety and efficacy of the LMA versus ETT in adenotonsillectomy.
METHOD
Databases were searched from inception to 2022 for randomized controlled trials and comparative studies. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The primary outcome is the rate of perioperative respiratory adverse events (PRAEs). Secondary outcomes included the rate of conversion to ETT, desaturations, nausea/vomiting, and surgical time. A subgroup analysis, risk of bias, publication bias, and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessments were also performed.
RESULTS
Twelve studies were included in the analysis (4176 patients). The mean overall conversion to ETT was 8.36% [95% confidence interval (CI) = 8.17, 8.54], and for the pediatric group 8.27% (95% CI = 8.08, 8.47). The mean rate of conversion to ETT secondary to complications was 2.89% (95% CI = 2.76, 3.03) while the rest was from poor surgical access. Overall, there was no significant difference in PRAEs [odds ratio (OR) 1.16, 95% CI = 0.60, 2.22], desaturations (OR 0.79, 95% CI = 0.38, 1.64), or minor complications (OR 0.89, 95% CI = 0.50, 1.55). The use of LMA yielded significantly shorter operative time (mean difference -4.38 minutes, 95% CI = -8.28, -0.49) and emergence time (mean difference -4.15 minutes, 95% CI = -5.63, -2.67).
CONCLUSION
For adenotonsillectomy surgery, LMA is a safe alternative to ETT and requires less operative time. Careful patient selection and judgment of the surgeon and anesthesiologist are necessary, especially given the 8% conversion to ETT rate.

Meta-Analysis
BACKGROUND
Pediatric sleep-disordered breathing (SDB) correlated with respiratory conditions of snoring and hypopnea. Mean platelet volume (MPV) was an inflammatory marker, related to increased inflammatory condition of pediatric patients. Increase of MPV level may cause failure to thrive or increased upper airway infection rate. The aim of this study was to perform systematic review and meta-analysis to investigate the difference on MPV values for pediatric SDB, and compare the change on MPV after surgery in patients with pediatric SDB.
METHODS
A systemic review of the studies from PubMed, EMBASE, and Cochrane Library databases was conducted in March 2020, supported by reviewing of published articles for studies comparing MPV in pediatric SDB. Meta-analysis was used to compare the change of MPV in pediatric SDB, and sub-group analysis was also used to compare the MPV decrease after surgeries of adenoidectomy or adenotonsillectomy.
RESULTS
There were seven studies included in the review. Six of them including 963 subjects showed that a significant increase of MPV was noted in pediatric SDB compared to those in pediatric non-SDB (P < 0.05). Total standardized mean difference (SMD) in MPV between pediatric SDB and non-SDB was 0.51 (95% CI =0.30-0.72, P < 0.05). A significant decrease of MPV was found in pediatric SDB patients who underwent surgery (total SMD = - 0.36; 95% CI = - 0.70- -0.02, P < 0.05). Decreases of MPV after adenoidectomy and adenotonsillectomy were observed, but only the effect of adenotonsillectomy had a statistical significance (total SMD = - 0.72; 95% CI = - 1.18 - -0.26, P < 0.05).
CONCLUSION
The MPV was significantly higher in patients with pediatric SDB, indicating the presence of increased platelet activity in pediatric SDB patients. The level of MPV could be reduced by the two surgeries, especially adenotonsillectomy.
