Meta-Analysis Review
OBJECTIVE
The purpose of this report was to discuss the overall limitations, safety and efficacy of flow-diverter stenting for intracranial aneurysms.
METHODS
The authors performed a meta-analysis from January 2009 to September 2014 using the terms "flow diverter" and "intracranial aneurysms." Additional studies were identified through references in each reviewed article. Data extraction, performed independently by the authors, included demographic data, technical and clinical complications, morbidity and mortality, aneurismal occlusion rates related to flow-diverter devices. The analysis was performed using a fixed effect.
RESULTS
Twenty-nine studies with 1524 patients and three to 62 months of follow-up were identified for analysis. The overall technical failure and complication rate was 9.3% (95% CI 6%-12.6%). The rate of procedure-related complication was 14% (95% CI 10.2%-17.9%) and 6.6% (95% CI 4%-9.1%) for morbidity and mortality. Fusiform, dissecting and circumferential aneurysm (OR 3.10, 95% CI 0.93-10.37) were significant risk factors for technical failure and complication. Posterior circulation location (OR 4.03, 95% CI 2.45-6.61), peripheral location (OR 2.74, 95% CI 1.52-4.94) and fusiform, dissecting and circumferential aneurysm (OR 1.95, 95% CI 1.15-3.30) were statistically significant risk factors for procedure-related complications. Posterior circulation location (OR 4.39, 95% CI 2.44-7.90) and peripheral location (OR 3.64, 95% CI 1.74-7.62) were statistically significant risk factors for morbidity and mortality.
CONCLUSIONS
Fusiform, dissecting and circumferential aneurysm, posterior circulation and peripheral locations have greater procedure-related complications.

Review
OBJECTIVE
To address the clinical question whether microsurgery hold an advantage in terms of clinical and patient oriented outcome over conventional macrosurgical procedures in the treatment of gingival recession.
MATERIAL AND METHODS
A Literature search on MEDLINE, SCOPUS, EMBASE (Excerpta Medica Database) via Ovid and Cochrane library was conducted in order to investigate clinical studies on efficacy of microsurgery in the treatment of localized or multiple gingival recession as compared to conventional macrosurgical procedures. Publications before May 2020 and grey literature was searched without any language restrictions. Primary outcome considered was change in recession depth and mean root coverage. Whereas, change in clinical attachment level, Change in keratinized tissue, patient oriented outcome like esthetics, pain and discomfort were the secondary outcome. Based on inclusion criteria ten studies were included in systematic review. Data was extracted and analyzed.
RESULTS AND CONCLUSION
All the included studies showed improvement in the mean percentage of root coverage or mean root coverage (primary outcome) when microsurgical approach was used. Predictability of complete root coverage is better with microsurgical instrumentation but results are not statistically significant. As far as patient centered outcome is concerned, there is no evidence for recommendation of microsurgery.

Meta-Analysis Review
INTRODUCTION/OBJECTIVES
The effects of hypnosis on acute pain have been discussed recently, resulting in increased attention in the dental/maxillofacial field offering new perspectives, especially in emergency situations, trauma, or acute inflammatory situations where conventional pharmaceuticals are contraindicated due to allergies or intolerance reactions.
DATA
To systematically evaluate and assess the effects of hypnosis on acute dental/facial pain relief. Randomized controlled trials, cohort studies, controlled clinical trials, cross-sectional studies, evaluation, and validation studies, following the PRISMA guidelines, of human subjects of all ages were included.
SOURCES
Five electronic databases (Cochrane, Embase, MEDLINE via PubMed, LILACS, Scopus) were screened for studies published between 1989 - 2021. A NIH quality-assessment-tool was performed.
STUDY SELECTION/RESULTS
27 papers have been included and a meta-analysis was performed. Hypnosis has been reported to reduce intraoperative and postoperative pain as well as the use of analgesics in various dental procedures such as tooth extraction. Highly hypnotizable subjects generally respond better to hypnosis. Different hypnosis techniques were used for pain relief and relaxation. The studies show a large heterogeneity.
CONCLUSION
Although there are only a small number of studies on the subject so far, evidence can be confirmed for the effects of hypnosis on acute pain relief in dental/maxillofacial area. Despite the promising results, further research is needed.
CLINICAL SIGNIFICANCE
Hypnosis offers a possible alternative to conventional pain medications for acute dental and maxillofacial pain, especially in cases of allergies or contraindications; it can be easily applied by a trained practitioner.

Meta-Analysis Review
INTRODUCTION/OBJECTIVES
The review systematically explored in vivo or in situ studies investigating the efficacy of nano-hydroxyapatite (nHA) to reduce initiation of or to remineralize initial caries lesions.
DATA
Prospective controlled (non-)randomized clinical trials investigating the efficacy of a nHA compared to any other (placebo) treatment or untreated/standard control.
SOURCES
Three electronic databases (Central Cochrane, PubMed-MEDLINE, Ovid EMBASE) were screened. Outcomes were, e.g., ICDAS score, laser fluorescence, enamel remineralization rate, mineral loss, and lesion depth. No language or time restrictions were applied. Risk of bias and level of evidence were graded using the Risk of Bias 2.0 tool and GRADE profiler.
STUDY SELECTION/RESULTS
Five in vivo (and 5 in situ) studies with at least 633 teeth (1031 specimens) being assessed in more than 420 (95) patients were included. No meta-analysis could be performed for in vivo studies due to the high heterogeneity of the study designs and the variety of outcomes. In situ studies indicate that under demineralization conditions, NaF was able to hinder demineralization, whereas nHA did not; simultaneously, nHA did not differ from the fluoride-free control. In contrast, under remineralizing conditions, nHA and NaF show the same remineralizing potential. However, the level of evidence was very low. Furthermore, six studies showed a high risk of bias, and six studies were funded/published by the manufacturers of the tested products.
CONCLUSION
The low number of clinical studies, the relatively short follow-up periods, the high risks of bias, and the limiting grade of evidence do not allow for conclusive evidence on the efficacy of nHA.
CLINICAL RELEVANCE
No conclusive evidence on the efficacy of nHA could be obtained based on the low number of clinical studies, the relatively short follow-up periods, the high risks of bias, the limiting grade of evidence, and study conditions that do not reflect the everyday conditions.

Review
Early childhood caries (ECC) is a multifactorial, biofilm-mediated, sugar-related, dynamic disease of primary dental hard tissues occurring in varying degrees of severity in infants and toddlers. Untreated ECC may lead to pain, infections, and severe systemic complications. The aim of this study was to systematically review and evaluate the scientific evidence on the cost-effectiveness of treatment decisions in ECC in infants and toddlers. Observational epidemiological studies, i.e., cohort studies, case-control studies, and randomized controlled trials, reporting cost-effectiveness of treatment decisions in ECC in infants and toddlers were included in the systematic review following the PRISMA guidelines. Using an ad hoc search with search terms or keywords (MeSH), electronic databases Embase, MEDLINE via PubMed, Scopus, and gray literature were searched. The search identified 494 articles, of which 446 remained after removing duplicates. A total of 417 articles were excluded after title and abstract evaluation; 29 full-text articles were screened for eligibility, and five articles were discarded. Twenty-four full-text articles were included in the systematic review, assigning 17 to prevention and seven to restoration. Results were heterogeneous; comparability of included studies is difficult because of the different methodologies used. Conflicting efficacies were demonstrated for different interventions implemented, and cost-effectiveness data were documented. Socioeconomic, cultural, and ethnic differences must be considered when comparing conditions in terms of cost-effectiveness. A paradigm shift from surgical towards preventive treatment decisions can be observed. Cost-effectiveness studies on therapies for ECC in infants and toddlers are needed to identify the best practice approach and the most cost-effective therapy decisions.

Review
Tourniquet-related nerve injuries (TRNIs) are a rare but feared complication of operative tourniquet use. While the literature contains multiple discussions regarding tourniquet use as well as reported cases of its complications, there does not exist a consensus guideline for a safe tourniquet pressure, application time, or management of TRNI. This paper conducts a comprehensive review of the available literature for cases of TRNI with a specific focus on analyzing the management of cases of TRNI and their functional recovery. One hundred nine articles were retrieved in a search of medical literature (PubMed) using the keywords: tourniquet, nerve injury, paralysis, and palsy. The initial search was further narrowed down to seven case series and 10 case reports totaling 203 reported cases of TRNI. Of the 203 cases, 64 cases involved upper extremity tourniquet use, and 139 cases involved lower extremity tourniquet use. Most patients (89.75%) experienced a complete recovery. TRNI may occur over a wide range of tourniquet application times and tourniquet pressures; hence, it is a necessity for surgeons to consider it as a potential complication and understand the methodology for diagnosis and long-term management.

Review
BACKGROUND
Animal-derived acellular dermal matrices (ADMs) are increasingly being used in prepectoral direct-to-implant (DTI) breast reconstruction. However, the indications and complication profile associated with this type of reconstruction remain unclear. This study aimed to perform a systematic review of the available literature on the use of animal-derived ADM in prepectoral DTI breast reconstruction.
METHODS
Three different literature databases, namely, PubMed, Web of Sciences, and Embase were screened using the following keywords: "immediate" AND "pre-pectoral" OR "prepectoral" AND "ADM breast reconstruction." Animal-derived ADM used (porcine - Braxon® and non-Braxon® - and bovine - Surgimend®) anthropometric information, clinical data, and complications profile were considered.
RESULTS
A total of 340 articles were initially identified, of which only 45 articles (5089 patients and 6598 reconstructed breasts) satisfied our inclusion criteria. The most widely used ADM was Braxon® in the context of conservative mastectomies. In most studies, a subcutaneous layer > 1 cm and lack of previous radiotherapy were considered prerequisites for this type of reconstruction. An increased risk of complications was found in smokers, patients who underwent radiation treatment, patients with high breast volumes, and patients with cancers requiring axillary dissection. Data related to the role of diabetes, high body mass index, and breast implant size on surgical outcomes were instead inconcludent. Age was not directly proportional to the complications.
CONCLUSION
The complications associated with different animal-derived ADMs are generally comparable. The profile of patients required for eligibility for this type of reconstruction appears to have been identified and is in line with current recommendations.

Review
Tympanoplasty is a reparative surgery that has multiple indications. The aid of a microscope or an endoscope is necessary to carry out the procedure. The classic method utilizes the microscope; however, in the recent decades, the endoscope has been popular. Although many articles try to compare these two techniques, there is still no robust evidence that confirms the superiority of either technique. In the present work, we seek to perform a systematic review contribute with this. The present systematic review attempted to compare endoscopic and microscopic surgery techniques and to discover whether there would be superiority in the results of any of them, based on data currently available in the literature. The objectives of the present review were organized according to the PICO planning and strategy adapted for systematic reviews. The inclusion and exclusion criteria were established aiming to select only select primary data. The main medical databases were searched using an optimized search string with appropriate descriptors. The searched databases were MEDLINE, LILACS, SciELO, and EMBASE. A total of 99 studies were selected and 38 were fully assessed after the inclusion criteria were applied. All included articles were reviewed by all authors and their results were discussed and summarized. The endoscopic technique was shown to be a safer technique comparable in effectiveness to the use of microscopy. In addition, it provides possible advantages such as shortening the surgical time and better postoperative pain outcomes.

Review
This systematic review addresses the crucial role of anticoagulation in microsurgical procedures, focusing on free flap reconstruction and replantation surgeries. The objective was to balance the prevention of thrombotic complications commonly leading to flap failure, with the risk of increased bleeding complications associated with anticoagulant use. A meticulous PubMed literature search following Evidence-Based-Practice principles yielded 79 relevant articles, including both clinical and animal studies. The full-texts were carefully reviewed and evaluated by the modified Coleman methodology score. Clinical studies revealed diverse perioperative regimens, primarily based on aspirin, heparin, and dextran. Meta-analyses demonstrated similar flap loss rates with heparin or aspirin. High doses of dalteparin or heparin, however, correlated with higher flap loss rates than low dose administration. Use of dextran is not recommended due to severe systemic complications. In animal studies, systemic heparin administration showed predominantly favorable results, while topical application and intraluminal irrigation consistently exhibited significant benefits in flap survival. The insights from this conducted systematic review serve as a foundational pillar towards the establishment of evidence-based guidelines for anticoagulation in microsurgery. An average Coleman score of 55 (maximum 103), indicating low overall study quality, however, emphasizes the need for large multi-institutional, randomized-clinical trials as the next vital step.

Meta-Analysis Review
Comparison of outcomes between tubular microdiscectomy and conventional microdiscectomy for lumbar disc herniation: a systematic review and meta-analysis of randomized controlled trials.
PURPOSE
The clinical outcomes of using a tubular microdiscectomy for lumbar disc herniation were evaluated by comparison with conventional microdiscectomy.
METHODS
All of the comparative studies published in the PubMed, Cochrane Library, Medline, Web of Science, and EMBASE databases as of 1 May 2023 were included. All outcomes were analysed using Review Manager 5.4.
RESULTS
This meta-analysis included four randomized controlled studies with a total of 523 patients. The results showed that using tubular microdiscectomy for lumbar disc herniation was more effective than conventional microdiscectomy in improving the Oswestry Disability Index (P < 0.05). However, there were no significant differences in operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate (all P > 0.05) between the tubular microdiscectomy and conventional microdiscectomy groups.
CONCLUSIONS
Based on our meta-analysis, it was found that the tubular microdiscectomy group had better outcomes than the conventional microdiscectomy group in terms of Oswestry Disability Index. However, there were no significant differences between the two groups in terms of operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate. Current research suggests that tubular microdiscectomy can achieve clinical results similar to those of conventional microdiscectomy. PROSPERO registration number is: CRD42023407995.
