OBJECTIVE
The successful management of odontogenic maxillary sinusitis (OMS) involves a combination of medical treatment with dental surgery and/or endoscopic sinus surgery (ESS). However, there is no consensus for the optimal timing of ESS. Although several studies have emphasized dental surgery as the primary treatment modality for OMS, there is recent evidence to suggest that ESS alone may be an effective treatment approach. The purpose of this study is to retrospectively investigate the pathophysiology of the current intractable OMS and the role ESS, especially ESS preceding dental treatment, plays in its pathophysiology.
METHODS
Ninety-seven adults (60 males and 37 females, 48 ± 12 years) who underwent ESS for intractable OMS were retrospectively examined.
RESULTS
In a great deal of the cases (85 cases, 87.6%), causative teeth of OMS were periapical lesions after root canal treatment (endodontics). The root canal procedures were not sufficient; hence, the root-canal-treated teeth had periapical lesions causing OMS. In postoperative nasal endoscopy and cone-beam CT scans for all patients, the natural ostiums and the membranous portions of the maxillary sinuses were enlarged and the ostiomeatal complexes remained widely open. The ventilation and drainage of all patients' maxillary sinuses seemed to be successfully restored. Temporary acute sinusitis recurrence after primary ESS for OMS was observed in 10 cases (11.8%) when the patients caught a cold. However, since the natural ostium and the membranous portion of the maxillary sinuses and the ostiomeatal complexes remained widely open, antibiotic administration alone without dental treatment cured the temporary acute sinusitis. Regarding the causative teeth (endodontic treated teeth), in 83 out of 85 cases (97.6%), causative teeth were able to be preserved with only antibiotic treatment and without dental retreatment. In two cases, extraction of the teeth was necessary because the teeth became mobile. Regarding the causative teeth after dental restoration, in 2 out of 2 cases (100%), causative teeth were able to be preserved with antibiotic treatment alone.
CONCLUSION
ESS is highly indicated for OMS requiring surgery. The treatment results of intractable OMS are exceptionally good once the ventilation and drainage of the maxillary sinus is successfully restored after surgery. Consequently, ESS can be considered the first-line therapy for intractable OMS caused by root canal treatment (endodontics) and dental restoration, followed by close dental follow-up and dental treatment when necessary.

Meta-Analysis Review
INTRODUCTION
The overall prevalence of maxillary sinusitis of odontogenic origin (MSOO) is still unknown. Therefore, this study aimed to determine the pooled prevalence of MSOO and verify associations between different odontogenic conditions and MSOO.
METHODS
Six electronic databases and the gray literature were searched on August 25, 2022. Two independent reviewers selected observational studies reporting the prevalence of MSOO and associated conditions in adults. Studies that did not use computed tomography for diagnosis were excluded. The methodological quality of the studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Cross-Sectional Studies. Data were analyzed by proportion and association meta-analyses. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Thirty-eight studies were included in the qualitative analysis and thirty-one in the meta-analyses. Only 12 studies (31.6%) fulfilled all items of the methodological quality checklist. Overall, the studies reported prevalence measures per maxillary sinus or patient. Thus, the pooled prevalence of MSOO was 51% per sinus (95% confidence interval [CI] [40%-61%]) and 50% per patient (95% CI [41%-59%]). Apical lesion (odds ratio [OR]: 4.03, 95% CI [2.26-7.19]), periodontitis (OR: 5.49, 95% CI [2.27-13.24]), moderate (OR: 2.57, 95% CI [1.85-3.57]) and severe bone loss (OR: 13.80, 95% CI [2.81-67.85] were significantly associated with MSOO. The certainty of the evidence for the associations was very low.
CONCLUSIONS
The pooled prevalence of MSOO on computed tomography assessment was 51% per maxillary sinus and 50% per patient. Therefore, half of the maxillary sinusitis may be of odontogenic origin. Apical lesion, periodontitis, and moderate and severe bone loss were significantly associated with MSOO.

BACKGROUND
Bacterial odontogenic sinusitis (ODS) is distinct from other forms of rhinosinusitis. Diagnosing ODS can be challenging because of nonspecific clinical presentations and underrepresentation in the literature. The purpose of this study was to compare maxillary sinus bacterial cultures between patients with ODS and chronic rhinosinusitis (CRS), to determine whether certain bacteria are associated with ODS.
METHODS
This was a retrospective case-control study of 276 consecutive patients from August 2015 to August 2019 who underwent endoscopic sinus surgery (ESS) for bacterial ODS, CRS without nasal polyps (CRSsNP), or CRS with nasal polyps (CRSwNP). When present, pus was sterilely cultured from maxillary sinuses after maxillary antrostomy, and aerobic and anaerobic cultures were immediately sent for processing. Demographics and culture results were compared between ODS and CRS patients, and then separately between ODS and CRSsNP, and ODS and CRSwNP. ODS culture results were also compared between different dental pathologies (endodontic vs oroantral fistula).
RESULTS
The following bacteria were significantly more likely in ODS compared to CRS: mixed anaerobes, Fusobacterium spp., Eikenella corrodens, Streptococcus intermedius, Streptococcus anginosus, and Streptococcus constellatus. Staphylococcus aureus and Pseudomonas aeruginosa were inversely related to ODS. There were no significant differences in cultures between the different dental pathologies.
CONCLUSION
Certain bacteria were more likely to be associated with ODS compared to CRS when purulence was cultured from the maxillary sinus. Physicians should evaluate for an odontogenic source of sinusitis when these ODS-associated bacteria are identified in maxillary sinus cultures.

Posttraumatic chronic maxillary sinusitis deleteriously affects the life quality of patients with recurrent episodes and related discomfort. However, few studies have been performed to investigate the prevalence of chronic maxillary sinusitis after surgery of mid-facial fracture and related risk factors. The early prevention and cure of posttraumatic chronic maxillary sinusitis have received little attention. This study aimed to investigate the prevalence of chronic maxillary sinusitis after surgery for mid-facial fracture and to identify related risk factors. The authors retrospectively collected the medical history, radiographic examination, and clinical examination of patients with mid-facial fracture (experimental group) and patients with mandibular cyst (control group) in our department between January 2015 and December 2020. A total of 298 patients (416 maxillary sinuses) in the experimental group and 172 patients (344 maxillary sinuses) in the control group were included for analyses. The prevalence of chronic maxillary sinusitis in the experimental group and control group were, respectively, 9.14% and 2.04% ( P < 0.05). History of sinusitis/rhinitis (odds ratio = 63.70, P = 0.000) was an independent risk factor for posttraumatic chronic maxillary sinusitis. In conclusion, these findings showed that the prevalence of chronic maxillary sinusitis after surgery for midfacial fracture was significantly higher than that in the control group and long-term follow-up may be beneficial for these patients. Moreover, patients with a history of sinusitis/rhinitis should be informed of the increased risk.

Review
PURPOSE
Endodontic disease is one of the most common causes of bacterial odontogenic sinusitis (ODS). Diagnosing ODS of endodontic origin involves otolaryngologists confirming sinusitis, and dental specialists confirming endodontic sources. The purpose of this study was to conduct a multidisciplinary literature review to highlight clinical and microbiological features of ODS, and the most optimal diagnostic modalities to confirm endodontic disease.
METHODS
An extensive review of both medical and dental literature was performed by rhinologists, endodontists, and an infectious disease specialist. Frequencies of various clinical and microbiological features from ODS studies were collected, and averages were calculated. Different endodontic testing and imaging modalities were also evaluated on their abilities to confirm endodontic disease.
RESULTS
ODS patients most often present with unilateral sinonasal symptoms for over 3 months, purulence on nasal endoscopy, and overt dental pathology on computed tomography (CT). Subjective foul smell, and maxillary sinus cultures demonstrating anaerobes and α-streptococci (viridans group) may be more specific to ODS. For endodontic evaluations, cold pulp testing and cone-beam CT imaging are most optimal for confirming pulpal and periapical disease.
CONCLUSION
Diagnosing ODS requires collaboration between otolaryngologists and dental specialists. Clinicians should suspect ODS when patients present with unilateral sinonasal symptoms, especially foul smell. Patients will generally have purulent drainage on nasal endoscopy, and both sinus opacification and overt dental pathology on CT. However, some patients will have subtle or absent dental pathology on CT. For suspected endodontic disease, endodontists should be consulted for at least cold pulp testing, and ideally cone-beam CT.

OBJECTIVE
Odontogenic maxillary sinusitis (OMS) is a well-recognized disease in otolaryngology and oral and maxillofacial surgery. It is diagnosed comprehensively based on the presence of dental disease and radiographic evaluation. Although the disease involves a combination of dental and otorhinolaryngological features, appropriate criteria have not been well established for prioritizing dental procedures in the initial treatment of OMS. We investigated whether computed tomography (CT) score, including the Lund-Mackay score, can help prioritize tooth extraction as the initial treatment for OMS.
METHODS
We also investigated the radiographic features of 32 patients with OMS treated by tooth extraction alone. Both pre-and post-extraction CT images of OMS cases were evaluated.
RESULTS
Lund-Mackay scores before tooth extraction were significantly lower in postoperatively healed patients than in non-healed patients. Furthermore, CT scores of the anterior and posterior ethmoid sinuses and frontal sinuses, obtained before tooth extraction, were significantly lower in postoperatively healed patients than in non-healed patients.
CONCLUSIONS
Collectively, low Lund-Mackay and CT scores of the ethmoid and frontal sinuses are significantly associated with healing of OMS treated by tooth extraction alone. The sinus CT score can help identify a treatment strategy for OMS.

OBJECTIVES
To clarify the performance of transfer learning with a small number of Waters' images at institution B in diagnosing maxillary sinusitis, based on a source model trained with a large number of panoramic radiographs at institution A.
METHODS
The source model was created by a 200-epoch training process with 800 training and 60 validation datasets of panoramic radiographs at institution A using VGG-16. One hundred and eighty Waters' and 180 panoramic image patches with or without maxillary sinusitis at institution B were enrolled in this study, and were arbitrarily assigned to 120 training, 20 validation, and 40 test datasets, respectively. Transfer learning of 200 epochs was performed using the training and validation datasets of Waters' images based on the source model, and the target model was obtained. The test Waters' images were applied to the source and target models, and the performance of each model was evaluated. Transfer learning with panoramic radiographs and evaluation by two radiologists were undertaken and compared. The evaluation was based on the area of receiver-operating characteristic curves (AUC).
RESULTS
When using Waters' images as the test dataset, the AUCs of the source model, target model, and radiologists were 0.780, 0.830, and 0.806, respectively. There were no significant differences between these models and the radiologists, whereas the target model performed better than the source model. For panoramic radiographs, AUCs were 0.863, 0.863, and 0.808, respectively, with no significant differences.
CONCLUSIONS
This study performed transfer learning using a small number of Waters' images, based on a source model created solely from panoramic radiographs, resulting in a performance improvement to 0.830 in diagnosing maxillary sinusitis, which was equivalent to that of radiologists. Transfer learning is considered a useful method to improve diagnostic performance.

OBJECTIVES/HYPOTHESIS
Acute rhinosinusitis is a frequent common cold-related complication in children. Despite the need for appropriate treatment, its underlying microbiology remains unclear. This study aimed to investigate the microbiology of acute rhinosinusitis in children.
STUDY DESIGN
Prospective non controlled study.
METHODS
Thirty-one pediatric acute maxillary sinusitis patients with severe symptoms were assessed. The subjects were 17 males and 14 females aged 5 to 14 years (mean age, 9.1 years). Maxillary sinus aspirates were collected and cultured, with subsequent viral and bacterial polymerase chain reaction (PCR) analysis. Bacteria were analyzed using culturing and PCR, and viruses were analyzed using PCR. The PCR kits used identify 18 types of respiratory viruses and 13 types of bacteria.
RESULTS
At least one pathogen was detected in 30 of 31 aspirates (97%) using PCR, and none of the aspirates contained respiratory viruses alone. Ten aspirates (32%) contained both viruses and bacteria. The most common viruses detected were rhinovirus (13%) and influenza virus (10%). The most common bacteria were Haemophilus influenzae (45%), Streptococcus pneumoniae (32%), Moraxella catarrhalis (16%), and Chlamydophila pneumoniae (13%). Bacteria were found in 21 of 31 cases (68%) via bacterial culturing. Culturing revealed that H influenzae was the most common pathogen (42%).
CONCLUSIONS
In pediatric acute maxillary sinusitis, respiratory bacteria were detected in 65% of the sinus aspirates and both bacteria and viruses in 32%. The most common viruses were rhinovirus and influenza virus, and the most common bacteria were H influenzae and S pneumoniae. Viral and bacterial PCR is useful for accurately investigating the microbiology in pediatric sinusitis.

The state of the nasal cavity, especially the region of the osteomyomatic complex, plays a significant role in the development of chronic maxillary sinusitis. Odontogenic maxillary sinusitis, as a complication of dental implantological treatment on the upper jaw, is increasingly common. The aim of the study was to increase the effectiveness of prophylaxis and treatment of odontogenic purulent upper jaw sinusitis during reconstructive operations on the alveolar region of the upper jaw. 3 groups of patients were examined: before dental treatment, after dental treatment in the development of odontogenic maxillary sinusitis and 30 patients were selected and examined, who underwent reconstructive surgeries on the alveolar process of the upper jaw and in whom the postoperative period was without complications. The diagnoses of 1st and 2nd group patients required surgical treatment. FESS allows restoring the physiological aeration of maxillary sinuses as naturally as possible, which is important for correct reparative bone regeneration in the alveolar region of maxilla.

Review
OBJECTIVE
We investigated the anatomical and dental factors associated with unilateral maxillary sinus fungal ball (MSFB). Also, we evaluated the effect of combinations of those factors on the incidence of MSFB.
METHODS
Three hundred patients were divided into MSFB, normal, and chronic rhinosinusitis (CRS) groups. We reviewed paranasal computed tomography scans for the presence of deviated nasal septum, concha bullosa (CB), Haller cells, and various dental factors. Also, we measured the ethmoid infundibulum, maxillary natural ostium, and CB.
RESULTS
Maxillary sinus fungal ball showed a more significant association with CB compared to the other 2 groups (37%, < .05). The MSFB group had a lower rate of Haller cells than the normal group (10% vs 22%, respectively; < .05). Also, the MSFB group had a wider maxillary sinus ostium than the normal group (7.07 ± 1.8 vs 5.48 ± 1.3 mm; < .01). Moreover, the combination of CB and Haller cells was significantly associated with a decreased rate of the fungal ball ( = .047, odds ratio = 0.694). The dental factors were more prevalent in the MSFB and CRS groups (73% and 75%, respectively) than in the normal group (32%, < .001).
CONCLUSIONS
Maxillary sinus fungal ball is significantly associated with CB, Haller cells, an increased maxillary sinus ostium size, and dental factors.
