The anatomic proximity of maxillary posterior teeth to the maxillary sinus provides a natural conduit for the spread of dental pathology into the maxillary sinus. This diffusion results in the development of sinus disease attributable to endodontic pathology, and is termed "maxillary sinusitis of endodontic origin" (MSEO). Ultimately, suspicion of odontogenic causes of sinus disease should come as a relief to the provider and patient alike as the conditions are very treatable by noninvasive means with high expected success. This article reviews the diagnosis and management of odontogenic sinusitis with an emphasis on CBCT imaging as part of the interdisciplinary diagnostic workup. Illustrative cases documenting the treatment of MSEO are also presented.

BACKGROUND: Oroantral fistula (OAF) involves pathological, epithelialized, and unnatural communication between the maxillary sinus and oral cavity. Recently, functional endoscopic sinus surgery has provided minimally invasive treatment options with fewer postoperative complications. The aim of the study was to evaluate the one-stage endoscopic middle meatal antrostomy (EMMA) technique with the application of a platelet-rich fibrin membrane (PRF) for OAF closure and maxillary sinusitis relief. PATIENTS AND METHODS: Patients who suffered from OAF with odontogenic sinusitis were included in this study. Complete excision of the epithelial tract and any necrotic tissue was performed with proper curettage. Then, EMMA was performed with simultaneous closure of the OAF by the application of PRF membranes that were fixed by sutures and covered with an acrylic splint. Patients were clinically evaluated for OAF closure, pain level, and symptom relief. Additionally, the size of the bone defect was measured with the aid of computed tomography (CT) preoperatively and after 24 weeks postoperatively. RESULTS: This study included nine eligible patients with a mean age of 38 years. The data were collected, tabulated, and statistically analyzed. Soft tissue healing and bone formation occurred in all patients who achieved maxillary sinusitis relief without any complications. Additionally, pain was significantly lower on the 7th postoperative day than on the 1st postoperative day, according to the statistical analysis of the results (p < .001). CONCLUSIONS: One-stage EMMA with the application of PRF membranes and acrylic splint represents a reliable alternative technique for OAF closure and maxillary sinusitis relief that is associated with a lower incidence of complications and minimal postoperative pain. TRIAL REGISTRATION: The trial was registered on 28/02/2024, at clinicaltrials.gov (ID: NCT06281873).

Differentiating orofacial odontogenic pain/disorders from pain/disorders associated with maxillary sinusitis is important to avoid unnecessary dentalprocedures and to properly refer patients to colleagues/dentists and vice versa. AIM: To analyze the association between apical lesions and sinus changes and to evaluate the agreement between the diagnoses of an endodontist, a radiologist, an oral and maxillofacial surgeon, and an otolaryngologist. MATERIALS AND METHOD: 385 axial, coronal, and sagittal MSCT scans were selected using an image archiving andcommunication system (PACS). The examinations had been performed between 2018 and 2022. RESULTS: Apical lesions were observed in 36.10% of sinusitis cases, 73.8% of unilateralsinusitis cases, 48.7% of sinus floor discontinuity cases, and 67.2% of cases in which endodontic treatment had been performed. Agreement between the diagnoses made by the endodontist and those made by the other investigators was high for most study variables (k > 0.60). The exceptions were mucosal thickening, for which agreement between the endodontist and the other investigators was intermediate (k=0.397), and the presence of periapicallesions (k=0.010), previous endodontic treatment (k=0.013), and mucosal thickness (k=0.024), for which agreement between endodontists and radiologists was low. Conclusions: There was an association between sinus changes and apical lesions.

Accidentally extruded root canal filler within the sinuses may induce maxillary sinusitis with fungal mass. The authors describe 2 cases of gutta-percha-induced fungal masses in the left maxillary sinus of 2 women. The lesions were evaluated preoperatively using both computed tomography and magnetic resonance imaging, providing comprehensive insights into the condition. In one patient, the lesion was located such that it could be resected through the middle meatal antrostomy alone. However, the second patient presented with an anteroinferiorly situated lesion that necessitated not only a transnasal approach but also an endoscopic modified medial maxillectomy. Both patients recovered uneventfully after surgery. This case series is the first published report of 2 cases of gutta-percha-induced maxillary sinus fungal masses, with their imaging findings, successfully treated through different routes through transnasal endoscopic surgery. These reports highlight the need for a collaborative approach between dental practitioners and otolaryngologists. In addition to the patient's wishes, surgical interventions must consider the unique characteristics of each case and the potential for collaboration across different medical specialties.

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.

INTRODUCTION: Orthognathic surgery can lead to sinus alterations, including sinusitis, attributed to the exposure of maxillary sinuses during Le Fort I osteotomy. Furthermore, being a hospital-based procedure, there is potential risk of complications arising from bacteria prevalent in such environments. This study evaluated maxillary sinusitis occurrence and the presence of multidrug-resistant bacteria in the nasal cavity before and after orthognathic surgery. METHODS: Ten patients with dentofacial deformities underwent Le Fort I osteotomy. Clinical evaluations using SNOT-22 questionnaire were performed, and nasal cavity samples were collected pre-surgery and 3-6 months post-surgery to quantify total mesophilic bacteria and detect Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella pneumoniae. Cone Beam Computed Tomography (CBCT) was performed pre- and post-operatively, and the results were evaluated using the Lund-Mackay system. This study was registered and approved by the Research Ethics Committee of PUCRS (No. 4.683.066). RESULTS: The evaluation of SNOT-22 revealed that five patients showed an improvement in symptoms, while two remained in the same range of interpretation. One patient developed post-operative maxillary sinusitis, which was not detected at the time of evaluation by SNOT-22 or CBCT. CBCT showed a worsening sinus condition in three patients, two of whom had a significant increase in total bacteria count in their nasal cavities. The Brodsky scale was used to assess hypertrophy in palatine tonsils, where 60% of the subjects had grade 1 tonsils, 20% had grade 2 and 20% had grade 3. None of the patients had grade 4 tonsils, which would indicate more than 75% obstruction. Two patients harboured S. aureus and K. pneumoniae in their nasal cavities. Notably, K. pneumoniae, which was multidrug-resistant, was present in the nasal cavity of patients even before surgery, but this did not result in maxillary sinusitis, likely due to the patients' young and healthy condition. CONCLUSION: There was an improvement in signs and symptoms of maxillary sinusitis and quality of life in most patients after orthognathic surgery. However, some patients may still harbour multidrug-resistant bacteria, even if they are asymptomatic. Therefore, a thorough pre-operative assessment is essential to avoid difficult-to-treat post-operative complications.

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/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.

OBJECTIVE: To assess the differences between endoscopic and radiological methods of analysis for diagnosing chronic maxillary sinusitis (CMS) in archaeological skeletal remains. MATERIALS: 32 crania from a Dutch post-medieval rural population. METHODS: We assessed the presence of bone changes indicative of CMS (i.e., bone growth and bone resorption) both endoscopically and through computed tomography (CT), and then compared results. RESULTS: We observed moderate agreement between bone growth scores obtained through endoscopy and CT, and fair agreement when assessing bone resorption. CONCLUSIONS: CMS prevalence rates observed through CT may be comparable to rates assessed endoscopically, although caution is needed when making direct comparisons. SIGNIFICANCE: This is the first study comparing data obtained through endoscopy and radiological methods in the study of CMS, informing paleopathologists about potential biases in data comparison. LIMITATIONS: Our small sample size likely impacted results. SUGGESTIONS FOR FURTHER RESEARCH: Further research is advised to fully explore the comparability of endoscopic and radiological method of analysis in the study of sinusitis. DATA AVAILABILITY: The datasets generated and analyzed during the current study are available upon request.

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.

OBJECTIVE: Maxillary sinusitis can be a sequela of medication-related osteonecrosis of the jaw (MRONJ). This study aims to characterize the microbiome of maxillary MRONJ with concurrent maxillary sinusitis and radiographic maxillary sinus opacification to determine if there is a relationship between the microbiome of MRONJ and sinus disease. STUDY DESIGN: This retrospective case series was conducted using electronic health records from the University of Pennsylvania and affiliated hospitals. The target population was surgically managed maxillary MRONJ patients. The primary predictor variables were tissue culture results. The primary outcomes were maxillary sinusitis or maxillary sinus opacification. Statistical analysis was performed using chi-squared tests at the 95% confidence interval. RESULTS: Thirty-nine subjects were selected: 25 had sinus opacification and 11 had sinusitis. Resident bacteria were present in 90% of subjects, nonresident bacteria in 74%, and opportunistic organisms in 15%. There were significantly more subjects with chronic sinusitis microbes (79%) than without. There were significantly more gram-positive anaerobes, specifically Propionibacterium, as well as the gram-negative facultative anaerobe, Capnocytophaga, in subjects with concurrent sinusitis. CONCLUSIONS: Maxillary MRONJ with concurrent maxillary sinusitis may be associated with gram-positive anaerobic species, Propionibacterium, and Capnocytophaga colonization. Maxillary MRONJ patients may benefit from sinus evaluation and concurrent surgical intervention.

Introduction: Odontogenic sinusitis is a frequent disease of the maxillary sinus, resulting from a dental inflammatory condition or a foreign body migrated in the sinus cavity. We performed a clinical retrospective study aimed to review the two surgical endoscopic approaches for odontogenic maxillary sinusitis middle and inferior meatotomy, in terms of realistic indications, efficacy, outcomes, and possible complications. Materials and Methods: In our study, we included a number of 400 patients with odontogenic maxillary sinusitis divided into two groups, treated in our hospital over five years, from January 2019 to December 2023. The patients included in this research were over 18 years old, diagnosed with odontogenic maxillary sinusitis, and underwent either middle meatal antrostomy or inferior meatotomy. Results: We examined the medical records of 400 patients. The vast majority of patients had a history of dental interventions, and the most affected tooth was the first maxillary molar. The symptoms at admission were typical for sinusitis: nasal obstruction, anterior or posterior rhinorrhea, hyposmia to anosmia, cacosmia, and pain or facial pressure. 80% of the patients in the study underwent middle meatal antrostomy, while 20% underwent inferior meatotomy. There were no significant differences between these two approaches in terms of efficacy, complication rates, recovery, or relapses. The complications that occurred after the surgical treatment were minor and with a very low frequency. The most reported were middle meatus synechiae and the persistence of the meatotomy ostium, with mucus recirculation (in patients with inferior meatotomy). Conclusions: Endoscopic surgical treatment of odontogenic maxillary sinusitis can be done as middle or inferior meatotomy, each having specific indications. The maxillary antrostomy is preferred in the majority of cases, as it is a procedure in which the natural ostium of the maxillary sinus is enlarged, thereby maintaining the natural drainage pathway of the sinus. However, the inferior meatotomy is preferred in the case of foreign bodies or maxillary sinus retention cysts localized at the level of the sinus floor or in the alveolar or lateral recesses, or as part of a combined approach (inferior and middle meatotomy), when the ablation of a "fungus ball" is required.

The article presents a case of chronic odontogenic maxillary sinusitis and the results of its surgical treatment. The cause of the sinusitis, confirmed by the results of X-ray and pathohistological studies, was an inflammatory process affecting the bone tissue around the implant, installed in the place of the upper first molar which was accompanied by the development of an oroantral fistula. During the surgical intervention, the communication between the oral cavity and the maxillary sinus was eliminated, and the implant with the abutment, which was entirely in its cavity, was also removed.

ABSTARCT: Odontogenic maxillary sinusitis (OMS) is a subtype of maxillary sinusitis (MS). It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion. Due to the lack of unique clinical features, OMS is difficult to distinguish from other types of rhinosinusitis. Besides, the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis. Its current diagnosis and treatment are thus facing great difficulties. The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS. However, this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality. Based on systematically reviewed literature and practical experiences of expert members, our consensus focuses on characteristics, symptoms, classification and diagnosis of OMS, and further put forward multi-disciplinary treatment decisions for OMS, as well as the common treatment complications and relative managements. This consensus aims to increase attention to OMS, and optimize the clinical diagnosis and decision-making of OMS, which finally provides evidence-based options for OMS clinical management.

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.

Maxillary osteotomies as a component of orthognathic surgery disrupt the normal anatomy and function of the sinus. The osteotomy with advancement of the inferior component of the sinus leaves a bony and mucosal opening in the sinus. Immediately after surgery, nasal drainage is impeded because of intranasal swelling. Acute and chronic maxillary sinusitis would be expected; however, its incidence as an expected complication is not well documented. A systematic review and meta-analysis was completed using PubMed to determine the incidence of sinusitis after maxillary orthognathic surgery. Studies were reviewed by two authors, and incidence data were extracted. Two hundred six articles were identified with 24 meeting the criteria for analysis. The incidence of sinusitis was based on 4213 participants who had undergone orthognathic surgery. Twenty-three studies reported a total number of sinusitis cases, and the results demonstrated a pooled incidence of 3.3% (95% confidence interval: 1.77, 6.06). One study did not report a total number of cases but reported chronic sinusitis survey-duration-based and Lund-Mackay scores. These scores, respectively, worsened from 7.6 to 14.8 and from 1.58 to 2.90 postoperatively. Despite the variability of maxillary surgery, the surgical technique, and the postoperative management, the incidence is low but sinusitis does occur. Prospective studies with validated questionnaires within the context of a specific protocol may further elucidate the causality of sinusitis. Further, patients with sinonasal symptoms postsurgery should be encouraged to consult with an otolaryngologist to ensure prompt treatment.
