Ectopic teeth, growing in abnormal locations like the maxillary sinus, are rare occurrences, with uncertain causes including trauma, infection, and developmental abnormalities. They often appear in the second or third decade of life, sometimes without symptoms. They are often missed as symptoms can mimic chronic sinusitis but may include sinonasal issues like obstruction and facial pain. Complications ranging from recurrence to potential blindness or carcinoma have been reported. Diagnosis involves radiographic imaging, with CT scans providing precise localization. Following accurate diagnosis, treatment typically involves surgical removal, with endoscopic procedures gaining popularity due to reduced risks. Follow-up for asymptomatic cases can be conducted through periodic radiographs. We report a case of maxillary ectopic tooth as an incidental finding in an asymptomatic patient presenting to the emergency department with head trauma.

OBJECTIVES
To determine which types of bone lesion (spicules, lobules, porous bone) in the maxillary sinus indicate sinusitis METHODS: Subadjacent dental disease is a cause of maxillary sinusitis; if a lesion type indicates sinusitis it should be more common above diseased posterior maxillary teeth than a lesion type that is not indicative of sinusitis. The study sample is a British Mediaeval human skeletal collection.
RESULTS
Porous bone lesions (chiefly new bone deposits) in maxillary sinuses are associated with subadjacent dental disease; spicules/lobules of bone in the sinus are not.
CONCLUSIONS
The results support the idea that porous lesions indicate sinusitis but the spicules/lobules may not. Spicules, lobules and porous lesions within the maxillary sinus should be analysed separately in biocultural studies; it would be prudent to regard only the porous lesions as indicative of sinusitis.
SIGNIFICANCE
Maxillary sinusitis is commonly used as a health indicator in palaeopathology, and spicular deposits are generally the most common type of alterations. By assuming that they are indicative of sinusitis we may have been greatly overestimating the prevalence of bony sinusitis in the past.
LIMITATIONS
These conclusions are provisional. Further work on larger, more diverse samples, together with more detailed anatomical studies on lesion location and structure is ongoing.

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.

BACKGROUND
Odontogenic maxillary sinusitis (OMS) is widely acknowledged in both the dentistry and otolaryngology fields. Recently, iatrogenic odontogenic maxillary sinusitis cases can be encountered frequently. The purpose of this study was to evaluate the effect of intraoral sinus irrigation using the small lateral window approach in patients with odontogenic maxillary sinusitis by comparing pre- and postoperative volumetric measurement of CBCT and symptoms. We surveyed 21 patients who visited the Oral and Maxillofacial Surgery Department at PNUDH from 2016 to 2022. All the patients' information was extracted from an electronic database. The patients with a follow-up period of 2 months or more were included. The three-dimensional volumetric measurement was performed using the ImageJ program (National Institute of Health, University of Wisconsin).
RESULTS
Among 21 patients, 16 (76.1%) were male, and 5 (23%) were female. The most common type of surgery was general anesthesia (16 cases) in which oroantral fistula was present in 7 cases. In the causes of maxillary sinusitis, there were seven implant-related patients, five patients of tooth extraction, seven patients of bone grafting, and two patients in other groups. Radiographic opacity decreased by 40.15% after sinus irrigation especially in bone graft and tooth extraction cases. Clinically, symptoms improved in 17 patients (80.9%).
CONCLUSION
By this study, it can be concluded that maxillary sinus irrigation using the small lateral window approach is a clinically and radiologically effective treatment method for odontogenic maxillary sinusitis.

OBJECTIVE
To construct the deep learning convolution neural network (CNN) model and machine learning support vector machine (SVM) model of bone remodeling of chronic maxillary sinusitis (CMS) based on CT image data to improve the accuracy of image diagnosis.
METHODS
Maxillary sinus CT data of 1000 samples in 500 patients from January 2018 to December 2021 in our hospital was collected. The first part is the establishment and testing of chronic maxillary sinusitis detection model by 461 images. The second part is the establishment and testing of the detection model of chronic maxillary sinusitis with bone remodeling by 802 images. The sensitivity, specificity and accuracy and area under the curve (AUC) value of the test set were recorded, respectively.
RESULTS
Preliminary application results of CT based AI in the diagnosis of chronic maxillary sinusitis and bone remodeling. The sensitivity, specificity and accuracy of the test set of 93 samples of CMS, were 0.9796, 0.8636 and 0.9247, respectively. Simultaneously, the value of AUC was 0.94. And the sensitivity, specificity and accuracy of the test set of 161 samples of CMS with bone remodeling were 0.7353, 0.9685 and 0.9193, respectively. Simultaneously, the value of AUC was 0.89.
CONCLUSION
It is feasible to use artificial intelligence research methods such as deep learning and machine learning to automatically identify CMS and bone remodeling in MSCT images of paranasal sinuses, which is helpful to standardize imaging diagnosis and meet the needs of clinical application.

OBJECTIVE
Optimization of the method of puncture treatment of acute bacterial maxillary sinusitis (ABMS) through the development of original devices for drainage of the maxillary sinus (MS).
MATERIAL AND METHODS
Registration and comparative analysis of the results of puncture methods of treatment of 120 patients with ABMS using developed new original devices for drainage of MS with one channels and with two channels in comparison with the Kulikovsky's needle (KN) was carried out. Based on the results of the analysis, the effectiveness of the original devices was assessed. During the clinical study, patients were divided into two groups: in group I, patients underwent of the MS puncture using KN, in group II, using original devices. Groups I and II, depending on the absence or presence of a block of the natural anastomosis MS, was divided into subgroups A and B, respectively. After puncture of the MS, the pain syndrome was assessed by patients using Visual Analogue Scale (VAS) and by doctors - using Touch Visual Pain (TVP) scale.
RESULTS
Our study showed that when puncturing the upper jaw with an original needle with one channels and with two channels, compared with the use of KN, there is a decrease in pain (the average VAS score was 1.5±0.3 and 1.7±0.3 points, respectively; the average TVP scale score was 0.9±0.2 and 1.8±0.3 points, respectively, the difference is significant, ≤0.05). Patients of subgroup IB were manipulated with two KN, patients of subgroup IIB manipulated using the original device with two channels without an additional needle (the average VAS score was 3.0±0.4 and 1.3±0.3 points, respectively; the average TVP scale score was 2.7±0.4 and 1.0±0.2 points, respectively, the difference is significant, ≤0.05). The doctors also assessed the devices used for puncture of the upper jaw. As a result of the study, the high efficiency and safety of using new original devices was established.

Maxillary sinus pathology is commonly approached through endoscopic middle meatal antrostomy (MMA). However, MMA does not provide full exposure to certain aspects of the maxillary sinus, such as alveolar, zygomatic, and prelacrimal recesses. In these hidden maxillary sinus niches, a combination approach with MMA is required for better exposure and access. In this article, we present a modification of inferior maxillary antrostomy (IMA) to allow for a temporary intraoperative window with no significant postoperative consequences. (1) To describe our modification of IMA. (2) To report the outcome of maxillary sinus disease, postoperative complications, and flap condition. This is a retrospective chart review study. It was performed on 20 patients where submucosal temporary inferior maxillary antrostomy (STIMA) was indicated in the period from January 1, 2020, and July 1, 2023. All patients were assessed for their demographics, diagnosis, indication for STIMA, maxillary disease outcome, presence of postoperative complications, and flap condition. Total of 18 patients fulfilled our inclusion/exclusion criteria; of them, 13 were males while the remaining were females. Mean age of patients was 33 years; most common diagnosis was chronic sinusitis. Status of maxillary sinus mucosa was healthy in all except 4 patients having polypoidal mucosa while flap condition was intact in all patients except 2 patients with pinpoint defects. Postoperative complications assessment demonstrated no neural, orbital, lacrimal, or dental complications in all patients. This retrospective chart review showed promising technique to address challenging maxillary lesions in difficult-to-access locations where combined approaches are necessary.

OBJECTIVE
The objective of this study is to investigate the association of peri-implantitis (PI) and sinus membrane thickening and to assess the resolution of membrane thickening following intervention (implant removal or peri-implantitis treatment) aimed at arresting PI.
MATERIALS AND METHODS
Forty-five patients with 61 implants in the posterior maxillary region were retrospectively included in the study. Twenty-four patients were diagnosed with peri-implantitis (PI) and 21 had peri-implant health (PH). Cone-beam computed tomography (CBCT) scans were evaluated to assess maxillary sinus characteristics, including membrane thickening, sinus occupancy and ostium patency. The CBCT scans taken 6 months after intervention aimed at arresting disease (implant removal or treatment of PI) in the PI group were also appraised and compared to baseline scans.
RESULTS
At baseline, all parameters evaluating membrane thickness disorders yielded significant differences between groups (p < .001). Patients with posterior maxillary implants diagnosed with PI were 7× more likely to present membrane thickening compatible with pathology when compared to patients with healthy implants (OR = 7.14; p = .005). Furthermore, the likelihood was 6x greater in implants diagnosed with PI to exhibit moderate membrane thickening (OR = 6.75, p = .001). The patients receiving interventions aimed at arresting PI experienced significant enhancement in all radiographic parameters related to the sinus cavity at the 6-month follow-up (p < .001), though these variations were similarly independent of whether treatment consisted of PI treatment or implant removal.
CONCLUSIONS
Maxillary sinus membrane thickening and the permeability/obstruction of the ostium are frequently associated with the presence of PI in posterior implants. Interventions targeting disease resolution effectively reduce membrane thickness to levels compatible with maxillary sinus health.

INTRODUCTION
Upper respiratory tract infections and sinusitis are more prevalent in children than in adults. Unilateral sinusitis is not uncommon disease. Our aim was to analyze the disease characteristics in children with unilateral sinusitis and compare them with those of adults.
MATERIALS AND METHODS
This study included 124 patients with unilateral chronic sinusitis divided according to age into two groups: pediatric group ≤18 years (66 cases) and adult group >18 years (58 cases). The groups were compared in terms of demographic data, side, clinical manifestations and radiological findings.
RESULTS
In pediatric patients, the most common inflammatory pathology was antrochoanal polyps, followed by allergic fungal sinusitis. On the other hand, chronic sinusitis without nasal polyps is the most common in adults, followed by antrochoanal polyps. The mean duration of clinical manifestations before diagnosis in pediatric patients was significantly shorter than that in adults (P=0.001). The most common symptoms in both pediatric and adult patients were anterior nasal discharge and nasal obstruction. Proptosis was significantly higher in pediatric group than in adult group (P=0.015). On computed tomography (CT), the most commonly affected sinus in both pediatric and adult patients was the maxillary sinus followed by the anterior ethmoid sinus. Bone expansion, erosion and involvement of adjacent structures were significantly higher in pediatric patients (P=0.028, 0.027 respectively).
CONCLUSION
Pediatric patients have a high incidence of antrochoanal polyps and allergic fungal sinusitis as unilateral inflammatory lesions. These lesions require surgical management. Inflammatory paranasal sinus lesions in pediatric patients have a shorter duration of clinical manifestations and a higher incidence of bone erosion and involvement of adjacent structures; therefore, early diagnosis and management prevent complications.
