Review
BACKGROUND
Culture-directed antibiotic therapy represents an important component in the management paradigm of chronic rhinosinusitis (CRS). The objective of this study was to systematically review the literature to assess culture yield of the most common aerobic and anaerobic pathogens.
METHODS
A total of 43 studies between 1975 and 2010 were included.
RESULTS
The composite data comprised 3528 patients with 6005 total culture specimens. The cultures were obtained in operating room in 33 (76.7%) and clinic in 10 (23.3%) of the studies, respectively. The most common site of culture was the maxillary sinus in 18 (41.9%) of the studies. The most common assay techniques reported were swab in 19 (44.2%) and aspirate in 12 (27.9%) studies. The most common gram positive aerobes reported were coagulase negative Staphylococcus and Staphylococcus aureus in 630 (34.7%) and 481 (26.5%) of the cultures, respectively. The most common gram negative aerobes included Haemophilus influenzae and Pseudomonas aeruginosa in 245 (27.0%) and 198 (21.6%) cultures, respectively. The most common anaerobes reported were Peptostreptococcus species in 156 (19.6%) and Bacteroides species in 153 (19.2%) cultures.
CONCLUSION
This study provides a composite snapshot of the literature accrued on the microbiology of CRS. It should serve to apprise clinicians on the most common aerobic and anaerobic organisms in CRS patients when employing culture-directed antimicrobial therapy.

Meta-Analysis
BACKGROUND
A study is made of the association between maxillary sinus pathology and odontogenic lesions in patients evaluated with cone beam computed tomography.
MATERIAL AND METHODS
A literature search was made in five databases and OpenGrey. Methodological assessment was carried out using the Newcastle-Ottawa tool for observational studies. The random-effects model was used for the meta-analysis.
RESULTS
Twenty-one studies were included in the qualitative review and 6 in the meta-analysis. Most presented moderate or low risk of bias. The periodontal disease showed to be associated with the thickening of the sinus membrane (TSM). Mucous retention cysts and opacities were reported in few studies. The presence of periapical lesions (PALs) was significantly associated to TSM (OR=2.43 (95%CI:1.71-3.46); I2=34.5%) and to odontogenic maxillary sinusitis (OMS) (OR=1.77 (95%CI: 1.20-2.61); I2=35.5%).
CONCLUSIONS
The presence of PALs increases the probability of TSM and OMS up to 2.4-fold and 1.7-fold respectively. The risk differences suggests that about 58 and 37 of out every 100 maxillary sinuses having antral teeth with PALs are associated with an increased risk TSM and OMS respectively. The meta-evidence obtained in this study was of moderate certainty, and although the magnitude of the observed associations may vary, their direction in favor sinus disorders appearance, would not change as a result.

PURPOSE
This meta-analysis and systematic review focused on the following question: Does tobacco smoking increase the risk of intra- or postoperative complications of lateral maxillary sinus floor elevation?
MATERIALS AND METHODS
The following electronic databases were searched up to and including November 2015 without language restriction: CENTRAL, MEDLINE, Google Scholar, Scopus, Sirous, and Doaj. Studies were included if rates of intra-or postoperative complications of sinus floor elevation in smokers and nonsmokers were recorded separately. The following complications were assessed: sinus membrane perforation, bleeding, wound dehiscence, wound infection, sinusitis, hematoma, and oroantral fistula. The Critical Appraisal Skills Programme was used to assess the risk of bias in included studies. Random-effects meta-analyses were used to assess the number of each complication in smokers and nonsmokers.
RESULTS
Out of 929 eligible publications, 11 articles were included. Meta-analysis of the studies revealed a significantly increased risk of developing wound dehiscence after sinus floor elevation among smokers compared with nonsmokers (Risk Ratio [RR]: 7.82; 95% confidence interval [CI]: 2.38, 25.74; P = .0007). Moreover, risk of developing wound infection was greater in smokers when prospective studies were included in the meta-analysis (RR: 5.33; 95% CI: 1.34, 21.25; P = .02). However, the meta-analysis of included studies did not show significant differences between smokers and nonsmokers concerning risk of sinus membrane perforation and bleeding during sinus floor elevation (P = .46 and P = .33, respectively).
CONCLUSION
Considering the lack of randomized controlled trials and the small number of included studies, the results indicate that smoking seems to be associated with increased risk of wound dehiscence and infection after the sinus augmentation procedure.

Review
The aim of the present systematic review was to investigate the clinical outcomes after the perforation of the maxillary sinus by dental implants, or after maxillary sinus membrane perforation during sinus lift procedure. Twenty-nine publications were included. Failure rates of implants in cases where perforation of sinus floor had happened (11 studies) was generally low, and only one case of transient sinusitis was reported. The estimated failure rate of these implants was 2.1% (SE 1.0%, = 0.035). There were 1817 implants (73 failures) placed in augmented sinuses in which the sinus membrane was perforated and 5043 implants (274 failures) placed in sinuses with no perforated membrane, from 18 studies. The odds of implant failure difference between the groups were not significant (OR 1.347, = 0.197). log OR of implant failure between perforated and non-perforated membrane groups did not significantly change with the follow-up time (-0.004/month; = 0.500). In conclusion, implant failure rate is generally low either for implants penetrating in the floor of the maxillary sinus or implants placed in augmented sinuses in which the sinus membrane was perforated. The prevalence of postoperative infection/sinusitis is low, and it may depend either on the dimensions of the perforation or on the anatomical predisposition.

American Journal of Rhinology & Allergy May 2021RARS is a challenging clinical phenomenon that affects many patients, and diagnostic criteria for this condition are not fully characterized in the literature.
BACKGROUND
RARS is a challenging clinical phenomenon that affects many patients, and diagnostic criteria for this condition are not fully characterized in the literature.
OBJECTIVE
To examine diagnostic criteria for recurrent acute rhinosinusitis (RARS).
STUDY DESIGN
Systematic review.
METHODS
Cochrane, PubMed (MEDLINE), clinicaltrials.gov, EMBASE, Google Scholar, and Web of Science databases were queried for articles related to RARS dating from 1990 to present, according to PRISMA statement guidelines. Full text articles pertinent to the diagnostic criteria of RARS were included in this review. Inclusion criteria included articles specifically addressing RARS; studies with 3 or more patients; and articles in English.
RESULTS
A total of 1022 titles/abstracts potentially related to RARS were identified. Of these, sixty-nine full texts were selected for review, and 22 of these ultimately met inclusion criteria. The level of evidence was generally low. Studies and guidelines have used many different definitions for RARS diagnosis over the years based on symptomatology, physical examination, nasal endoscopy, imaging, and laboratory domains. Clinically important RARS has been defined most commonly as 4 or more discrete episodes of ARS per year, but this frequency is typically based on expert opinion. Additionally, radiologic anatomic associations such as concha bullosa, accessory maxillary os, and narrowed infundibular distance may be associated with RARS. Endoscopic visualization and imaging are sometimes used to confirm the presence of sinus disease during exacerbations of RARS, but there is variability in this practice.
CONCLUSION
The diagnostic definition for RARS has developed over time and is currently based on low level 4 and 5 evidence. Because of the migratory definition of RARS, comparing inter-study results of RARS management remains difficult, and future studies should aim to follow current expert guidelines on diagnostic criteria of RARS.

Review
Cone-beam computed tomography (CBCT) imaging of the maxillary sinus is indispensable for implantologists, offering three-dimensional anatomical visualization, morphological variation detection, and abnormality identification, all critical for diagnostics and treatment planning in digital implant workflows. The following systematic review presented the current evidence pertaining to the use of artificial intelligence (AI) for CBCT-derived maxillary sinus imaging tasks. An electronic search was conducted on PubMed, Web of Science, and Cochrane up until January 2024. Based on the eligibility criteria, 14 articles were included that reported on the use of AI for the automation of CBCT-derived maxillary sinus assessment tasks. The QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2) tool was used to evaluate the risk of bias and applicability concerns. The AI models used were designed to automate tasks such as segmentation, classification, and prediction. Most studies related to automated maxillary sinus segmentation demonstrated high performance. In terms of classification tasks, the highest accuracy was observed for diagnosing sinusitis (99.7%), whereas the lowest accuracy was detected for classifying abnormalities such as fungal balls and chronic rhinosinusitis (83.0%). Regarding implant treatment planning, the classification of automated surgical plans for maxillary sinus floor augmentation based on residual bone height showed high accuracy (97%). Additionally, AI demonstrated high performance in predicting gender and sinus volume. In conclusion, although AI shows promising potential in automating maxillary sinus imaging tasks which could be useful for diagnostic and planning tasks in implantology, there is a need for more diverse datasets to improve the generalizability and clinical relevance of AI models. Future studies are suggested to focus on expanding the datasets, making the AI model's source available, and adhering to standardized AI reporting guidelines.

INTRODUCTION
Ectopic sinonasal teeth are uncommon. The classic approach to removal of such foreign bodies was the Caldwell-Luc. In recent years however, endoscopic approaches have become increasingly utilized. Despite this, there is a dearth of literature and consensus regarding the endoscopic removal of ectopic sinonasal teeth. As such, we conducted a systematic review on all cases of endoscopic removal of ectopic sinonasal teeth in the literature. With an understanding of the literature, clinical and technical decision making for patients with this pathology may be elucidated.
METHODS
Systematic review of the Ovid Medline, EMBASE Classic and Pubmed databases were conducted using PRISMA guidelines.
RESULTS
Our search identified 100 articles. Final inclusion consisted of 23 studies with a total of 27 patient cases. The majority of the patients included were male (70.4%) with a mean age of 27.06 years. Patients presented with a multitude of symptoms, with nasal obstruction (48.14%), rhinorrhea (22.2%), facial pain (22.2%) and epistaxis (22.2%) being most common. Surgeons mostly reported using a 0° endoscope (22.2%) and performing a maxillary antrostomy/uncinectomy (37%) and simple extraction under general anesthetic (41%).
CONCLUSIONS
This systematic review analyzed important epidemiological, clinical and technical information regarding patients with endoscopic removal of sinonasal ectopic teeth. Further research is needed to promote implementation of such data into clinical practice.

Meta-Analysis
OBJECTIVE
To determine the range of incidental mucosal changes in a general sinonasally asymptomatic population on radiology.
DATA SOURCES
Medline (1996-present) and Embase (1974-present) were searched on March 14, 2020, to identify articles that reported radiological sinus mucosal findings in asymptomatic population groups. Bibliographic search of included studies was conducted to identify additional articles.
REVIEW METHODS
The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Cochrane Handbook for Systematic Reviews of Interventions. A comprehensive search strategy was formulated and articles screened to extract data reporting Lund-Mackay (LM) score, presence of mucous retention cysts, and maxillary mucosal thickening. A random-effects model was used in meta-analysis.
RESULTS
A total of 950 articles were identified, of which 33 manuscripts met the inclusion criteria. The included studies involved 16,966 sinonasally asymptomatic subjects. The mean LM score was 2.24 (95% CI, 1.61-2.87), and an LM score of ≥4 in 14.71% (95% CI, 6.86-24.82%) was present across all general asymptomatic population groups. Mucous retention cysts were noted in 13% (95% CI, 8.33-18.55%) and maxillary mucosal thickening of ≥2 mm in 17.73% (95% CI, 8.67-29.08%).
CONCLUSION
The prevalence of incidental mucosal changes in a general asymptomatic population on radiology needs to be considered when making a diagnosis of chronic rhinosinusitis.

BACKGROUND
The use of zygomatic implants in the prosthetic rehabilitation of the patient with severe maxillary bone atrophy is another therapeutic alternative, not exempt from complications. The main objective of this review is to analyze and describe the most frequent surgical complications associated with the use of zygomatic implants.
MATERIAL AND METHODS
An electronic database search on PubMed, along with a manual search, without taking into account date nor language, was undertaken by two observers, selecting studies that comprised a study period from 6 to 12 months, any type of clinical trial, and series that included a follow-up and/or review period during the aforementioned margin, that mentioned at least two types of complications.
RESULTS
Out of the initial search that yielded 455 studies, 67 were considered potentially relevant for the present study, out of which 14 were finally selected. Out of the most frequent surgical complications, sinusitis (3,9%) and failure in osseointegration (2,44%) are highlighted.
CONCLUSIONS
The analysis of the results shows that the most frequent complications are sinusitis and failure in osseointegration of the zygomatic implant. However, a standardised data collection system for the data on complications is needed.
