RESUMEN
A comunicação bucossinusal (CBS) é uma complicação relativamente frequente na prática odontológica que ocorre em procedimentos cirúrgicos, principalmente, exodontias dos molares superiores. O diagnóstico dessa comunicação é feito através de exames clínicos intraorais, empregando a manobra de Valsava, e para a confirmação do diagnóstico, utiliza-se exame radiográfico. A literatura cita inúmeros métodos de tratamento, entretanto não evidenciam a técnica específica para cada caso, entre esses métodos existe o retalho com o corpo adiposo da bochecha, que apresenta alto índice de sucesso no fechamento das CBS. Quando a CBS é fechada incorretamente ou de forma tardia o paciente fica propício a desenvolver quadros de sinusite crônica ou aguda, além de fístulas bucossinusais. Portanto, deve-se identificar e tratar essa comunicação de imediato para evitar o desenvolvimento de outras complicações. O objetivo do presente trabalho é apresentar um caso clínico de um paciente com comunicação bucossinusal atendido na clínica odontológica da Unidade de Ensino Superior de Feira de Santana (UNEF), com a finalidade de demostrar a técnica cirúrgica utilizando a rotação do corpo adiposo da bochecha (Bola de Bichat).
The bucosinusal communication (BCS) is a relatively frequent complication in dental practice that occurs in surgical procedures, especially extractions of the upper molars. The diagnosis of this communication is made through intraoral clinical examinations, using the Valsava maneuver, and for the confirmation of the diagnosis, radiographic examination is used. The literature cites numerous methods of treatment, however they do not evidence the specific technique for each case, among these methods there is the graft with the adipose body of the cheek, which has a high success rate in the closure of the CBS. When the CBS is closed incorrectly or late, the patient is prone to develop chronic or acute sinusitis, in addition to bucosinusal fistulas. Therefore, this communication should be identified and treated immediately to prevent the development of other complications. The objective of the present study is to present a clinical case of a patient with bucosinusal communication attended at the dental clinic of Unidade de Ensino Superior de Feira de Santana (UNEF), with the purpose of demonstrating the surgical technique using the rotation of the adipose body of the cheek (Bichat ball).
RESUMEN
The article explores the understudied pathophysiology of odontogenic sinusitis (ODS) development as a result of oral surgical complications such as oroantral communication (OAC) or fistula (OAF), maxillary sinus bone grafting, and dental implantation. A temporary OAC presents most often after dental extraction, especially with posterior maxillary teeth, though can happen with any oral surgical intervention. Maxillary sinus augmentation can also cause ODS, and while the pathophysiology is incompletely understood, it may be related to OAC/OAF formation or bone graft infection. Dental implants may also lead to ODS either via displacement into the sinus, partial protrusion into the sinus, or peri-implantitis.
RESUMEN
OBJECTIVES: Endoscopic sinus surgery (ESS) is often necessary when managing odontogenic sinusitis (ODS), but ESS extent for ODS with extramaxillary sinus involvement has been incompletely studied. This study compared outcomes after wide maxillary antrostomy (MA) alone versus complete ESS for ODS with frontal sinus involvement. METHODS: A multicenter prospective cohort study was conducted on patients with uncomplicated ODS (no extrasinus spread) who underwent ESS when computed tomography demonstrated maxillary, anterior ethmoid (AE), and frontal sinus opacification. Multiple preoperative and postoperative variables were recorded, including 22-item sinonasal outcome tests (SNOT-22) and endoscopic findings. Ultimate SNOT-22 and endoscopic resolution, and time to SNOT-22 and endoscopic resolution were compared between patients who underwent MA alone versus "complete" ESS (maxillary, ethmoid, frontal; not sphenoid). RESULTS: Of 70 patients, mean age was 59.2 years, and 55.7% were male. Thirty-five underwent MA alone, and 35 had complete ESS. At first postoperative visits (mean 9.3 days), AE sinus purulence was more likely resolved after complete ESS compared with MA (97.1% vs. 71.4%, p = 0.006). However, time to resolution of AE purulence was comparable by 6 weeks postoperatively (p = 0.158). There were no significant differences in times to foul smell resolution and achieving ≥9 point SNOT-22 reduction (p > 0.05). CONCLUSIONS: For ODS with frontal sinus involvement, MA alone and complete ESS both resulted in rapid and long-term symptomatic resolution. While ultimate resolution of sinus purulence was equivalent between surgery groups, complete ESS did lead to faster resolution of frontoethmoidal purulence in a significant number of cases.

RESUMEN
The article provides an in-depth review focused on diagnosing oral surgery-related complications that may cause odontogenic sinusitis (ODS). It emphasizes the importance of evaluating patients with prior oral surgical procedures to determine whether the prior procedure is an ongoing infectious source of the ODS. Specifically, diagnostic evaluations will be described for detecting oroantral communications and fistulas, dental implant dislocation or protrusion, and whether implants and graft placed in maxillary sinuses are infected. It highlights the role of different oral examination techniques, optimal imaging modalities, and the importance of otolaryngologic collaboration to evaluate for infectious ODS.
RESUMEN
Primary dental treatments for odontogenic sinusitis (ODS) due to endodontic infections (pulpal necrosis and apical periodontitis ± periapical abscess) include extraction and root canal treatment (RCT). Published evidence is lacking on the success of primary endodontic treatment for purulent ODS, with the majority of RCT-related series reporting on its success at resolving reactive maxillary sinus mucositis. Dental extraction is the most definitive treatment of endodontic disease causing ODS, but compromises the functional dentition and still often fails to resolve the purulent sinusitis. This article highlights key concepts of RCT and dental extraction techniques, as well as their published success at resolving ODS.
RESUMEN
This article reviews the optimal management of oroantral fistulas, implants protruding into the maxillary sinus, implants completely displaced into the sinus(es), and infected bone grafts used for sinus augmentation. For each scenario, multidisciplinary management strategies will be considered based on whether there is concurrent infectious odontogenic sinusitis. A multidisciplinary approach with oral surgeons and otolaryngologists is often mandatory to ensure optimal therapeutic outcomes.
RESUMEN
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.
RESUMEN
Oroantral communications (OACs) are relatively common complications after extractions of maxillary posterior teeth. Some defects can heal spontaneously, while others require surgical treatment. The lack of an appropriate therapeutic approach can lead to the epithelialization of the OAC that causes a permanent connection between the two cavities, called an oroantral fistula (OAF), and subsequent chronic sinusitis. Various treatment modalities have been used in cases of OACs, including advancement flaps, bone grafts, synthetic materials, and barrier membranes. We present two cases of closure of OACs with dense polytetrafluoroethylene (d-PTFE) membranes (of FDI tooth #28 in the first case and #17 in the second case), which were left exposed to the oral cavity. In both cases, healing was uneventful.
RESUMEN
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).

Las fístulas bucosinusales son complicaciones poco frecuentes originadas a partir de comunicaciones bucosinusales de larga trayectoria o no tratadas que predisponen a desarrollar cuadros patológicos tales como infecciones, sinusitis y un establecimiento crónico de la fístula si no es tratada de manera apropiada y oportuna. El tratamiento indicado es el cierre quirúrgico de esta comunicación, la cual puede ser lograda mediante múltiples técnicas; siendo el tamaño, localización y compromiso de los tejidos blandos circundantes los factores principales para considerar una técnica por sobre otra. El siguiente artículo tiene como objetivo presentar el manejo de una fístula bucosinusal de larga data en un paciente de 71 años con antecedentes médicos de radioterapia de cabeza y cuello.
Oroantral fistulae are rare complications originating from non-treated or long-term oroantral communications which can contribute to the development of certain pathological entities such as local infections, sinusitis and chronic fistula formation. The treatment modality indicated is surgical closure of the communication, which can be achieved through multiple techniques, being the size, location and nearby soft tissue the main factors for considering one technique over another. The objective of the following article is to present the management of an oroantral fistula in a 71 year old patient with a medical history of head and neck radiotherapy.
RESUMEN
OBJECTIVES: The aim of this work was to systematically review and carry out a statistical metanalysis to identify the best treatment for close oroantral communications and fistulas and to avoid the risk of recurrence. MATERIALS AND METHODS: An electronic search was conducted on the MEDLINE database (Pubmed), Scopus, and Google scholar using the following keywords: "oro antral communication (OAC)" OR "oro antral fistula (OAF)" OR "antro-oral communication" OR "communication between maxillary sinus and oral cavity" OR "oro-sinusal communication" OR "oro-sinusal fistula" OR "sinus communication" OR "sinus fistula" OR "antral communication" AND "treatment" OR "management" OR "surgical treatment" OR "surgical interventions". This work was performed in accordance with the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses). After article screening, 9 RCTs (randomized controlled trials), comparing two or more techniques, were included in this review. RESULTS: A statistically significant difference was detected in favor of the buccal fat pad compared to the buccal advancement flap and palatal rotational flap. CONCLUSIONS: With the limitations of this study, the buccal fat pad showed the best results in terms of communication closure and reducing the risk of relapse.
RESUMEN
Background: Amniotic membrane (AM) holds significant promise in various medical fields due to its unique properties and minimal ethical concerns. This study aims to explore the diverse applications of the human amniotic membrane (HAM) in maxillofacial surgery. Methodology: A comprehensive search was conducted on databases, namely Google Scholar, PubMed, and Scopus, from January 1985 to March 2024. Articles in English, Polish, and Spanish were included, focusing on keywords related to amniotic membrane and oral surgery. Results: Various preservation methods for HAM were identified, namely fresh, decellularized, cryopreserved, lyophilized, and air-dried formats. Clinical studies demonstrated the efficacy of HAM in repairing oral mucosal defects, vestibuloplasty, oronasal fistula closure, cleft palate treatment, bone defect repair, and medication-related osteonecrosis of the jaw (MRONJ). Surgeon evaluations highlighted the ease of handling but noted challenges in suturing and stability during application. Conclusions: Amniotic membranes offer a versatile and effective option in maxillofacial surgery, promoting wound healing, reducing inflammation, and providing a scaffold for tissue regeneration. Further research, including randomized trials and comparative studies, is warranted to validate the efficacy and optimize the utilization of HAM in clinical practice.

BACKGROUND: An oroantral fistula is a communication between the maxillary antrum and oral cavity. This pathological communication is formed mainly due to dental extraction of maxillary premolars and molars. Adequate management should include closing the oroantral fistula and eliminating sinus infections to prevent recurrence and sinusitis. PURPOSE: This study aimed to evaluate the effectiveness of using the pedicled buccal periosteal flap for closing an oroantral fistula without changing the native intraoral structure. PATIENTS & METHODS: Patients with oroantral fistulas were included in this study. The patients were examined clinically by Valsalva test and cheek-blowing test, the hole was probed, and the extent of the underlying bone defect was determined radiographically using computed tomography preoperatively. All patients underwent surgical closure of oroantral fistula using a pedicled buccal periosteal flap. RESULTS: All 10 patients obtained satisfactory results with marked improvement in the function of the maxillary sinus and complete healing of oroantral fistula with no recurrence except in Case No. 5, who had a recurrence of the oroantral fistula, also there was no statistically significant difference between the vestibular depth preoperatively and postoperatively. CONCLUSION: A pedicled buccal periosteal flap is a novel technique for oroantral fistula closure as it preserves vestibular depth with a tension-free closure flap and harbors the advantages of the regenerative potential of the periosteum.

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.

Closing a recurrent oroantral fistula (OAF) that occurs at an infected sinus augmentation site is a challenge for clinicians. The recurrent OAF has a detrimental impact on bone regeneration and subsequent implant placement. This case report includes three cases in which sinus graft infection and OAF occurred after maxillary sinus augmentation (MSA). In these cases, treatments to control sinus infection were performed using an otolaryngologist; then, intraoral interventions comprising mucosal flap procedures, bone grafts, and barrier membrane applications were performed 2-5 times by oral surgeons. Nevertheless, OAF recurred persistently. The failure to stop OAF recurrence may be due to the inability to effectively block air pressure at the OAF site. Following a comprehensive debridement of the infected tissue at the previous sinus augmentation site, a pouch was created through sinus mucosal elevation. The perforated sinus mucosa at the OAF site was covered with a non-resorbable membrane in one case and with resorbable collagen membranes in the other two cases, followed by bone grafting within the pouch. Lastly, this procedure was completed by blocking the entrance of the pouch with a cortical bone shell graft and a resorbable collagen membrane. The cortical bone shell graft, obstructing the air pressure from the nasal cavity, facilitated bone formation, and, ultimately, allowed for implant placement. Within the limitations of the present case report, the application of a guided bone regeneration technique involving a cortical bone shell graft and a barrier membrane enabled the closure of the recurrent OAF and subsequent implant placement.

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.

Background: Odontogenic maxillary sinusitis caused by a foreign body presents diagnostic and therapeutic challenges due to its infrequent occurrence and unique characteristics compared to sinusitis originating from other sources. CaseReport:Illustrating such fact, this report presents the clinical case of a 37-year-old woman referred complaining of pain in the same region where she had extracted her upper right first molar five days before. The intraoral examination revealed the presence of an orifice in the region, suggesting oroantral communication. Imaging exams revealed opacification of the right maxillary sinus and the unexpected presence of a highly radiodense object. With the diagnosis of maxillary sinusitis due to a foreign body established, the surgical approach initially consisted of administering preoperative medication, preceded by access to the maxillary antrum using the Caldwell-Luc technique. The object was found and removed, consisting of a surgical drill. At follow-up there was complete absence of symptoms and complete closure of communication. Conclusion: Cases of odontogenic maxillary sinusitis caused by drill detachment after tooth extraction are fairly uncommon. A thorough clinical evaluation proved to be essential and the Caldwell-Luc access was effective, safe and with good postoperative results, even with the absence of standardized diagnostic and management methods(AU)
Contexto: A sinusite maxilar odontogênica causada por corpo estranho apresenta desafios diagnósticos e terapêuticos devido à sua ocorrência infrequente e características únicas em comparação com sinusites originadas de outras fontes. Relato do Caso: Ilustrando tal fato, este relato apresenta o caso clínico de uma mulher de 37 anos de idade encaminhada com queixa de dor em mesma região que havia extraído o primeiro molar superior direito cinco dias antes. Ao exame intraoral verificou-se a presença de um orifício na região, sugerindo comunicação oroantral. Os exames de imagem revelaram opacificação do SM direito e a inesperada presença de um objeto altamente radiodenso. Com o diagnóstico de sinusite maxilar por corpo estranho estabelecido, a abordagem cirúrgica consistiu inicialmente na administração de medicação pré-operatória, precedida pelo acesso ao antro maxilar através da técnica de Caldwell-Luc. O objeto foi encontrado e removido, consistindo em uma broca cirúrgica. Ao acompanhamento houve ausência completa dos sintomas e total fechamento da comunicação. Conclusão: Casos de sinusite maxilar odontogênica causada por descolamento da broca após extração dentária são bastante incomuns. Uma avaliação clínica minuciosa mostrou-se primordial e o acesso de Caldwell-Luc eficaz, seguro e com bons resultados pós-operatórios, mesmo com as ausências de métodos de diagnóstico e manejo padronizados.(AU)

IgG4-related disease (IgG4-RD) is an immune-mediated disorder that involves multiple organs and is characterized by the infiltration of lymphoplasmacytic cells, including IgG4-positive plasma cells, along with storiform fibrosis and obliterative phlebitis in the inflamed organs. The primary sites affected by this condition include the pancreas, bile ducts, salivary glands, aorta, lungs, kidneys, meninges, lacrimal glands, mediastinal lymph nodes, and retroperitoneum. The pathogenesis is linked to a type 2 T-helper-cell cytokine profile and the involvement of regulatory T cells. However, the exact mechanism is still unknown. Patients with IgG4-related disease are frequently misdiagnosed as having malignancies due to the resemblance of the lesions to infections or other immune-mediated diseases and certain tumors, such as pancreatic cancer and pseudo-renal pelvis tumor. Prompt identification of IgG4-related disease is essential as a delayed diagnosis until advanced stages can result in severe organ damage and potentially fatal outcomes, despite the disease being highly responsive to treatment. This report presents a highly unusual case of IgG4-related disease (IgG4-RD) with an atypical presentation in a 38-year-old female patient. The patient sought medical attention in the emergency department due to nasal septal erosions and an oral-antral fistula. Nasal cultures were conducted and indicated the presence of Klebsiella ozaena. Subsequent investigations, including a nasal biopsy, confirmed the diagnosis of IgG4-related autoimmune disease.
RESUMEN
Oroantral communication is an unnatural communication of the maxillary sinus with the oral cavity, often resulting from dental extractions, infection, trauma, or excision of cysts or tumors. Pathological epithelialization of oroantral communication leads to oroantral fistula. Various techniques have been proposed for surgical closure. Uneventful healing of the defect can be achieved in the absence of antral infection. Hence, medical management of maxillary sinusitis should precede surgical closure of the defect. Here, we report a case of an oroantral fistula of the left maxillary third molar, caused by a secondary infection of the extraction site, managed primarily by antibiotics, topical steroids, and irrigating agents followed by surgical closure. It is essential to carefully inspect the post-extraction socket of maxillary teeth due to its high risk of development of oroantral communication. Also, the management of oroantral communications needs early detection to prevent infection and to prevent transforming into an oroantral fistula. In case of an infected oroantral communication or fistula, priority rests on treating the infection first and followed by surgical repair.
