RESUMO
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.

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.

PURPOSE: This study aimed to evaluate the utility of large language model (LLM) artificial intelligence tools, Chat Generative Pre-Trained Transformer (ChatGPT) versions 3.5 and 4, in managing complex otolaryngological clinical scenarios, specifically for the multidisciplinary management of odontogenic sinusitis (ODS). METHODS: A prospective, structured multidisciplinary specialist evaluation was conducted using five ad hoc designed ODS-related clinical scenarios. LLM responses to these scenarios were critically reviewed by a multidisciplinary panel of eight specialist evaluators (2 ODS experts, 2 rhinologists, 2 general otolaryngologists, and 2 maxillofacial surgeons). Based on the level of disagreement from panel members, a Total Disagreement Score (TDS) was calculated for each LLM response, and TDS comparisons were made between ChatGPT3.5 and ChatGPT4, as well as between different evaluators. RESULTS: While disagreement to some degree was demonstrated in 73/80 evaluator reviews of LLMs' responses, TDSs were significantly lower for ChatGPT4 compared to ChatGPT3.5. Highest TDSs were found in the case of complicated ODS with orbital abscess, presumably due to increased case complexity with dental, rhinologic, and orbital factors affecting diagnostic and therapeutic options. There were no statistically significant differences in TDSs between evaluators' specialties, though ODS experts and maxillofacial surgeons tended to assign higher TDSs. CONCLUSIONS: LLMs like ChatGPT, especially newer versions, showed potential for complimenting evidence-based clinical decision-making, but substantial disagreement was still demonstrated between LLMs and clinical specialists across most case examples, suggesting they are not yet optimal in aiding clinical management decisions. Future studies will be important to analyze LLMs' performance as they evolve over time.

Chronic odontogenic maxillary sinusitis (COMS), a prolonged inflammation of the maxillary sinus lasting over 12 weeks, is often a result of periapical lesions, marginal periodontitis, and complications like oro-antral communication (OAC) and fistula (OAF). OAC, commonly emerging post-teeth extraction in the lateral maxilla, lacks documented treatments using advanced platelet-rich fibrin (A-PRF). This study evaluates A-PRF's efficacy in treating COMS and immediately sealing extensive OAC. A case of a 28-year-old male with COMS linked to a periapical lesion and supernumerary molars is presented. Treatment involved extracting specific teeth while preserving adjacent ones and using A-PRF for immediate OAC closure. A-PRF, enriched with growth factors, was pivotal in healing, showcasing enhanced tissue regeneration, pain reduction, and faster recovery. The findings suggest A-PRF as an effective adjunct in treating extensive OAC and COMS, proposing its inclusion in standard treatment protocols. This study underscores A-PRF's potential in improving outcomes for patients with COMS and related complications.

BACKGROUND: Sinusitis is a commonly encountered clinical condition that imposes a considerable burden on the healthcare systems. A significant number of maxillary sinus opacifications are diagnosed as sinusitis, often overlooking the precise differentiation between cystic formations and inflammatory sinusitis, resulting in inappropriate clinical treatment. This study aims to improve diagnostic accuracy by investigating the feasibility of differentiating maxillary sinusitis, retention cysts, and normal sinuses. METHODS: We developed a deep learning-based automatic detection model to diagnose maxillary sinusitis using ostiomeatal unit computed tomography images. Of the 1080 randomly selected coronal-view CT images, including 2158 maxillary sinuses, datasets of maxillary sinus lesions comprised 1138 normal sinuses, 366 cysts, and 654 sinusitis based on radiographic findings, and were divided into training (n = 648 CT images), validation (n = 216), and test (n = 216) sets. We utilized a You Only Look Once based model for object detection, enhanced by the transfer learning method. To address the insufficiency of training data, various data augmentation techniques were adopted, thereby improving the model's robustness. RESULTS: The trained You Only Look Once version 8 nano (YOLOv8n) model achieved an overall precision of 97.1%, with the following class precisions on the test set: normal = 96.9%, cyst = 95.2%, and sinusitis = 99.2%. With an average F1 score of 95.4%, the F1 score was the highest for normal, then sinusitis, and finally, cysts. Upon evaluating a performance on difficulty level, the precision decreased to 92.4% on challenging test dataset. CONCLUSIONS: The developed model is feasible for assisting clinicians in screening maxillary sinusitis lesions.
RESUMO
OBJECTIVES: To assess the performance of deep learning (DL) in the detection, classification, and segmentation of maxillary sinus diseases. MATERIALS AND METHODS: An electronic search was conducted by two reviewers on databases including PubMed, Scopus, Cochrane, and IEEE. All English papers published no later than February 7, 2024, were evaluated. Studies related to DL for diagnosing maxillary sinus diseases were also searched in journals manually. RESULTS: 14 of 1167 studies were eligible according to the inclusion criteria. All studies trained DL models based on radiographic images. Six studies applied to detection tasks, one focused on classification, two segmented lesions, and five studies made a combination of 2 types of DL models. The accuracy of the DL algorithms ranged from 75.7% to 99.7%, and the area under curves (AUC) varied between 0.7 and 0.997. CONCLUSION: DL can accurately deal with the tasks of diagnosing maxillary sinus diseases. Students, residents, and dentists could be assisted by DL algorithms to diagnose and make rational decisions on implant treatment related to maxillary sinuses.

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, p≤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, p≤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.

BACKGROUND/AIM: Odontogenic maxillary sinusitis is a clinically popular disease, but radical surgery and endoscopic surgery are often required. In the present study, we compared for the first time the therapeutic efficacy of the extraction of causative teeth with or without irrigation of the extraction fossa. PATIENTS AND METHODS: A total of 60 patients underwent extraction of causative tooth. Among them, 34 patients underwent irrigation, while other 26 patients did not. Based on computed tomography (CT) images, treatment efficacy was quantified by the percentage of the remaining maxillary sinus mucosal lesions. The extent of therapeutic efficacy was evaluated following five grades, based on the percentage of remaining lesions: Grade 1 (0%) (disappearance of lesions), Grade 2 (roughly 10%), Grade 3 (roughly 30%), Grade 4 (approximately 50%) and Grade 5 (100%) (no improvement of the lesions). RESULTS: Irrigation significantly augmented the therapeutic efficacy of tooth extraction for maxillary sinus mucosal lesions (mean grade: decreasing from 3.27 to 1.35). CONCLUSION: The combination of tooth extraction and irrigation may contribute to the reduction of the necessity of surgery for the maxillary sinuses.

Introduction: Odontogenic maxillary sinusitis (OMS) is an infectious inflammatory pathology caused by a dental condition. Considering the anatomical relations with the orbit, maxillary sinus infection can easily spread, evolving into severe oculo-orbital complications that can sometimes be life-threatening. Material and methods: We performed a retrospective study of over 2 years, examining the data of 18 patients diagnosed with OMS with oculo-orbital complications. The patients were evaluated regarding their dental history, symptoms, clinical and endoscopic findings, ophthalmologic evaluation, bacteriologic tests, computed tomography (CT) imaging, medical and surgical treatment, and outcomes. Results: The age of the patients was between 24 and 65 years old with an almost equal gender distribution: 10 female and 8 male patients. From the total, 7 patients had type II diabetes, 2 of whom were insulin-dependent, 1 patient had thrombophilia and 2 patients had renal failure with peritoneal dialysis. Regarding the type of oculo-orbital complications, 10 patients were diagnosed with preseptal cellulitis and 8 with orbital cellulitis. Just 5 patients with orbital cellulitis required surgical treatment and orbitotomy was performed, followed by endonasal endoscopic drainage. The evolution after surgical treatment was favorable for all operated patients. Discussions: Oculo-orbital complications of OMS are typically more severe than those of rhinogenic sinusitis because anaerobic bacteria are involved. Immunosuppression represents a favorable environment for the development of OMS and its complications, diabetes being the most common risk factor. A negative prognostic feature is the appearance of ophthalmological symptoms in both eyes, so visual function may be reduced. The treatment of oculo-orbital complications of OMS is urgent and depends on a broad-spectrum antibiotic therapy associated or not with surgical intervention. Conclusions: The diagnosis of oculo-orbital complications of OMS is complex and requires clinical experience as well as extensive medical knowledge to treat both the cause and the consequences of the conditions quickly and effectively. The proper management of oculo-orbital complications is based on a multidisciplinary team: ophthalmology, ENT, dentistry, imaging, and laboratory. Abbreviations: OMS = odontogenic maxillary sinusitis, CT = computed tomography, ENT = ear-nose-throat, MRI = magnetic resonance imaging, HNS = head and neck surgery.

Objectives: To investigate the clinical efficacy of dental treatment and endoscopic sinus surgery (ESS), each primary/combined treatment modality, in patients with odontogenic sinusitis (ODS), according to its phase, acute or chronic. Materials and methods: We retrospectively reviewed clinical data on 172 patients diagnosed with ODS. They were divided into two groups: acute (≤ 3 months; 90 patients) and chronic (> 3 months; 82 patients) ODS. The success rate and time to resolution of each primary/combined treatment modality were compared between the two groups. Results: In both ODS groups, the success rate was highest with combined ESS and dental therapy, followed by ESS alone and dental therapy alone. ESS outperformed dental therapy (96.6% vs 65.5% for acute ODS, p = 0.011; 80.6% vs 56.5% for chronic ODS, p = 0.046) and led to quicker resolution of symptoms for acute ODS than dental therapy (0.9 vs 1.7 months, p = 0.012). In the comparison between ESS alone and combined therapy, no significant difference was observed for acute ODS, whereas combined therapy demonstrated a superior success rate for chronic ODS (100% vs 80.6%, p = 0.046). Conclusions: In our study, the clinical utility of dental treatment and/or ESS depended on the morbidity period of ODS. For chronic ODS, combined ESS and dental treatment seems to be an effective first-line treatment.
RESUMO
Introduction: Ectopic foreign bodies in the maxillary sinus occur rarely. Ectopic tooth eruption rarely occurs in the orbit, nasal cavity, maxillary sinus, and elsewhere. Ectopic eruption of teeth in the maxillary sinus is most commonly associated with wisdom teeth and is rarely associated with supernumerary teeth. This rare phenomenon may be accompanied by chronic recurrent sinusitis with headaches and facial pain. However, fibro-osseous lesions in the paranasal sinuses are discovered incidentally on X-ray images and are often asymptomatic. Osteoma is the most common fibro-osseous lesion that develops in the paranasal and nasal sinuses. Osteomas rarely cause serious symptoms such as orbital lesions and intracranial invasion. Case Presentation: We report a rare case of exostosis containing supernumerary teeth within the maxillary sinus. A characteristic pedicled bone lesion with a clear border on computed tomography was the undefined orthopantomogram radiopacity in the maxillary sinus, and the lesion contained supernumerary teeth. As the patient had chronic nasal congestion, the tumor was surgically removed. Pathologically, the surgical specimen revealed an osteoma. The patient's symptoms of chronic sinusitis disappeared. Because the patient had no history of midface trauma or surgery, the supernumerary teeth were speculated to have migrated during a reactive osteogenic process caused by chronic sinusitis. Conclusions: A foreign body in the maxillary sinus can be easily diagnosed by computed tomography. Surgical removal is recommended if the foreign body is symptomatic or occupies more than half of the maxillary sinus. This can help resolve chronic sinusitis symptoms and prevent serious complications in the future.
RESUMO
OBJECTIVES: Endoscopic medial maxillectomy (EMM) is an effective intervention for patients with recalcitrant maxillary sinusitis after previous middle meatal antrostomy. The pathophysiology of refractory maxillary sinusitis is incompletely understood. We aim to identify trends in structured histopathology (SHP) to better understand how tissue architecture changes contribute to refractory sinusitis and impaired mucociliary clearance. METHODS: All patients who underwent EMM or standard maxillary antrostomy for recalcitrant maxillary sinusitis of various forms were included. Retrospective chart review was conducted to collect information on demographics, disease characteristics, comorbid conditions, culture data, and SHP reports. Chi-squared and logistic regression analyses were performed for SHP variables. RESULTS: Forty-one patients who underwent EMM and 464 patients who underwent maxillary antrostomy were included. On average, the EMM cohort was 10 years older (60.9 years vs. 51.1 years; p = 0.001) and more often had a history of prior sinus procedures (73.2% vs. 40.9%; p < 0.001). EMM patients had higher rates of fibrosis (34.1% vs. 15.1%, p = 0.002), and this remained statistically significant when controlling for prior sinus procedures and nasal polyposis (p = 0.001). Cultures positive for pseudomonas aeruginosa (38.2% vs. 5.6%, p < 0.001) and coagulase negative staphylococcus (47.1% vs. 23.5%, p = 0.003) were more prevalent in the EMM group. CONCLUSION: Fibrosis and bacterial infections with Pseudomonas and coagulase negative Staphylococcus were more prevalent in patients requiring EMM. This may contribute to the multifactorial etiology of impaired mucociliary clearance in patients with recalcitrant maxillary sinusitis. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:2646-2652, 2024.

BACKGROUND: Subtypes of sinusitis have different symptoms and prognoses due to different pathogens. Odontogenic maxillary sinusitis (OMS) mainly occurs unilaterally and is different from chronic rhinosinusitis (CRS) usually occurring bilaterally in terms of clinical characteristics. However, comprehensive microbiological comparisons between OMS and CRS have never been systematically conducted and most comparisons are methodologically biased. This study aims to provide a comprehensive analysis of the microbiology associated with OMS and CRS through a meta-analysis approach in order to provide evidence for differential diagnosis of OMS and CRS from a microbiological perspective. METHODS: The databases PubMed and CNKI were searched from their inception to July 2023. A random-effects model was employed to derive the pooled prevalence estimates of the identified bacterial species or genera. RESULTS: The 17 represented studies included 6 concerning OMS, 12 concerning CRS, and 4 concerning normal sinus, yielding 191, 610, and 92 samples, respectively. Though not statistically significant, the prevalence of Peptostreptococcus and Prevotella was generally higher in OMS compared to CRS. Notably, Fusobacterium was identified as the only genus with a significantly higher prevalence in OMS compared to CRS. CONCLUSION: Fusobacterium was significantly more prevalent in OMS compared with CRS, while Staphylococcus aureus was more prevalent in CRS than in OMS. Such differences in bacterial profile may partly explain the distinct pathology observed and contribute to the development of novel strategies for diagnosis and therapeutic interventions in OMS.
RESUMO
OBJECTIVE: To investigate the association of perforation of the maxillary sinus floor by dental implants with mucosal thickening and to describe its characteristics in perforated cases. STUDY DESIGN: One-hundred and twenty-nine maxillary sinuses of 93 patients presenting 202 dental implants in the maxillary posterior region were retrospectively assessed in cone-beam computed tomography scans and classified according to maxillary sinus perforation, bone graft, mucosal thickening, and mucosal appearance. Logistic regression determined the chance of mucosal thickening in perforated maxillary sinuses. The chi-square test compared categorical variables between maxillary sinus perforated or not by implants and maxillary sinus with or without mucosal thickening. The significance level assumed was 5 % (α = 0.05). RESULTS: There was perforation of 60 maxillary sinuses floor (46.5 %) by 74 dental implants. The chance of mucosal thickening was higher when the implant tip was trespassing on the maxillary sinus floor (p < 0.001). There was a significant association between maxillary sinus mucosal thickening and perforation by a dental implant with the tip trespassing the maxillary sinus floor (p < 0.05). CONCLUSION: Maxillary sinus mucosal thickening is associated with sinus floor perforation by dental implants and does not depend on the number of implants perforating it. CLINICAL RELEVANCE: There is an association between dental implants' perforation of the maxillary sinus floor and the thickening of the maxillary sinus. In those cases, the appearance of the mucosa thickening may be irregular, local, or total opacification of the sinus cavity.

Extrapulmonary tuberculosis is an infrequently reported condition. However, in endemic settings, it contributes to a significant number of cases. The most common site of extrapulmonary tuberculosis is the lymph nodes. Herein, an exceedingly rare case of extrapulmonary tuberculosis presenting as bilateral cervical lymphadenitis with external cerebral watershed infarct along with sphenoid and maxillary sinusitis in an Indian male is presented. A detailed literature search revealed that a case with all these clinical conditions together has never been reported to date. A diagnostic workup supported by radiometric investigations helped in the diagnosis, and timely management was initiated.
RESUMO
An invasive pneumococcal disease involving sternoclavicular joint arthritis, lumbar spondylodiscitis, and muscular abscesses caused by penicillin-resistant Streptococcus pneumoniae has not been reported previously. We successfully treated a 57-year-old man with this condition using surgical drainage and debridement, and laminectomy/fenestration, in combination with the administration of two IV antimicrobial drugs based on blood culture results. Clinical resolution was obtained after decompression of the lumbar spine, with minimal restriction of the left lower limb. This treatment approach should be considered depending on the pathogen, underlying host factors, and the severity of the disease.
RESUMO
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.
RESUMO
Bacterial odontogenic sinusitis (ODS) arises from maxillary dental issues or oral procedures, and affects at least the maxillary sinuses, with or without other paranasal sinus involvement. It has been historically underreported, in contrast to more recent findings attributing 25-40% of chronic maxillary sinusitis to dental causes. Endodontic infections represent one of the most common causes of ODS. Endodontic factors like root canal infection and microbial proximity to sinus cavities play pivotal roles. Host immunological responses further shape disease severity and progression. This article aims to explore the complexity of endodontic infections that cause ODS, elucidating anatomical, microbial, and immunological aspects.
RESUMO
Odontogenic sinusitis is the most common cause of isolated maxillary sinusitis. Accurate diagnosis is important to ensure optimal treatment. We discuss the unique presentation of a 55-year-old man with odontogenic sinusitis and associated infraorbital nerve neuropathy. We document his later development of chronic maxillary atelectasis and discuss the possible underlying pathophysiology linking this with his infraorbital neuropathy.
