The Rarity of Maxillary Osteomyelitis: Insights From a Unique Case Report.

Maxillary osteomyelitis is a rare bone infection and is rarer to come across with the advent of advanced antibiotic therapies. It is often linked to immunocompromised conditions, namely diabetes mellitus, cancer, and chronic alcoholism, as they increase the chances of developing osteomyelitis. We present a rare case of maxillary osteomyelitis along with an infraorbital abscess in a 32-year-old male patient with uncontrolled diabetes. The patient complained of dental pain, facial swelling, and visual disturbances. The patient was managed with sequestrectomy along with curettage, incision, and drainage of orbital abscess. The patient responded well to surgery and had no complications post-surgery. As radiographic signs may present late, the authors aim to highlight the significance of thorough clinical examination and good patient history. Prompt radical treatment is necessary to avoid any severe consequences.

Comparison of the histopathological characteristics of diffuse sclerosing osteomyelitis of the mandible, chronic suppurative osteomyelitis, and craniofacial fibrous dysplasia.

BACKGROUND: There are relatively few reports on the histopathological characteristics of diffuse sclerosing osteomyelitis of the mandible (DSOM), which is difficult to distinguish from chronic suppurative osteomyelitis (CSO) and craniofacial fibrous dysplasia (CFD). This study aimed to summarize and compare the histopathological characteristics of DSOM, CFD, and CSO. MATERIALS AND METHODS: In this study, hematoxylin and eosin-stained sections of patients with DSOM, CSO, and CFD at the Peking University Hospital of Stomatology from 2015 to 2020 were retrieved. The histopathological characteristics were summarized, including new bone formation, inflammatory cell infiltration, bone trabecular morphology, osteoclasts, sequestrum, bacterial mass, and calcified spherules, similar to cementicles. The histopathological characteristics of DSOM, CSO, and CFD were compared, and the results were statistically analyzed. RESULTS: In total, 50, 13, and 10 patients with DSOM, CSO, and CFD were included in this study, respectively. In terms of new bone formation, both DSOM and CSO showed reactive bone formation (p = 1), whereas CFD mainly showed fiber osteogenesis (p < 0.001). The inflammatory cells of DSOM were mainly lymphocytes and plasma cells, whereas those of CSO were mainly lymphocytes and neutrophils (p < 0.001), and there was usually no inflammatory cell infiltration in the CFD specimens (p < 0.001). DSOM, CSO, and CFD showed irregular bone trabeculae (p = 0.045, p = 0.703) and active osteoclasts (p1 = 0.189, p2 = 0.256). DSOM showed a small amount of bacterial mass but no sequestrum; neither of which was found in CFD (p = 1, p = 1), but it was common in CSO (p = 0.011 and p = 0.025). DSOM and CSO showed smooth and regular basophilic lines (p = 0.308), whereas CFD showed a rough and irregular basophilic line (p < 0.001). CONCLUSIONS: The histopathological characteristics of the three diseases were partly similar, but there were evident differences. The main differences are the type of new bone formation, types and distribution of inflammatory cells, and presence of sequestrum and bacterial masses. These differences will help clinicians diagnose DSOM.

Decompressive effects of draining tube on suppurative and sclerosing osteomyelitis in the jaw.

BACKGROUND: Osteomyelitis (OM) in the jaw is an inflammatory disease of osseous tissue that begins in the medullary space and progressively expands to the cortical portion of the bone, the Haversian system, the periosteum and the overlying soft tissue. Despite advances in dental and medical care, OM persists and is of important concern in modern medicine. Active negative pressure is known to prevent post-operative hematoma; decrease the number of bacterial pathogens, accumulation of toxins, and necrotic tissue; and promote osteogenesis and angiogenesis with the use of a draining tube such as the Jackson-Pratt (JP) or Hemovac. The purpose of this study was to assess the effectiveness of decompression for the treatment of OM in the jaw. METHODS: This retrospective study included a total of 130 patients, 55 patients with sclerosing OM and 75 patients with suppurative OM were included. The radiographic bone densities expressed as a grayscale values (GSVs), were measured using an easy digitalized panoramic analysis (EDPA) method, processed on the conditional inference tree, generated by the R program® 3.2.3 with a probability of 96.8%. Rectangle annotation analysis of INFINITT PACS® (INFINITT Healthcare, Seoul, Korea) of 50 mm2 was determined as the region of interest (ROI). Student's t-test and ANOVA were used to determine significance (p < 0.05). RESULTS: Significant changes was observed between radiographic bone density in the sclerosing type with drain and without drain at the six-month and one-year follow-up (p < 0.05). Significant difference was demonstrated between the suppurative OM with drain and without drain groups at the one-year follow-up (p < 0.05). CONCLUSION: The OM groups with drain exhibited more enhanced bone density compared to the groups without drain at the six-month and one-year follow-ups. The drain insertion for decompression is effective for the management of sclerosing and suppurative OM. It is recommended to implement it for the management of OM.

Garré's Sclerosing Osteomyelitis with Perimandibular Soft Tissue Inflammation and Fistula.

Garré's sclerosing osteomyelitis is a form of chronic osteomyelitis that commonly affects children and young adults. Here, we report one such case of Garré's sclerosing osteomyelitis in a 20-year-old female who presented with facial asymmetry and inability to open mouth. On clinical examination, it was bony hard swelling with trismus. History of infected second molar tooth extraction was present. Computed tomography scan showed thickening and sclerosis of the ramus and condylar process of mandible, on right side, with proliferative periostitis. Magnetic resonance imaging showed soft tissue edema and inflammation, in the form of enlargement of right masseter and pterygoid muscles with intramuscular fluid collection. On the basis of history, clinical signs, and imaging features, diagnosis of Garré's osteomyelitis with fascial space infection was made. To our knowledge, very few cases of Garré's osteomyelitis present with superimposed fascial space infection, as it is otherwise a nonsuppurative condition. Fistula formation is a very rare incidence as it is seen in our case.

Garre's Sclerosing Chronic Osteomyelitis of Femur in an Adolescent.

Introduction: Garre's sclerosing osteomyelitis (GSO) is a rare chronic inflammatory disease resulting in thickening of cortices with loss of medullary canal without any signs of active infection. Case Report: A 13-year-old boy presented in 2017 with the right thigh pain of 3 years duration, who had exhausted all conservative attempts. We operated the patient with intramedullary reaming with antibiotic-impregnated cement augmented Kuntscher nail, which got jammed. The nail was subsequently removed and left-over cement pieces required an extended trochanteric osteotomy with aggressive curettage. The intra-operative culture was negative at all times, but histopathology suggested chronic inflammation. The patient had complete relief of symptoms at 2 years follow-up with all acute phase reactants reaching baseline and no further periosteal deposition. A follow-up magnetic resonance imaging was not possible due to stainless steel implants in situ. Conclusion: GSO is a confusing diagnosis that must exclude other mimickers and may recur even after surgical debridement.

Florid cemento-osseous dysplasia associated with chronic suppurative osteomyelitis and multiple impacted tooth an incidental finding - A rare case report.

Florid cemento-osseous dysplasia (FCOD) is a rare, benign, fibro osseous, and multifocal dysplastic lesion of the jaw that consists of cellular fibrous connective tissue with bone and cementum-like tissue. The word 'florid' was introduced to describe the wide spread, extensive manifestations of the disease in the jaws. FCOD is most commonly found in middle-aged, black women with the prevalence of 5.5%. Reports from Indian population is even rarer, with only 5 cases in literature, Florid cemento-osseous dysplasia is generally asymptomatic, and is usually detected during radiological examination. In this report, we present a case of a 44-year-old female patient diagnosed with Chronic diffuse osteomyelitis of the mandible later, on radiographic examination revealed FCOD, secondarily infected with Chronic diffuse osteomyelitis and multiple impacted tooth.

Response of Different Treatment Protocols to Treat Chronic Non-Bacterial Osteomyelitis (CNO) of the Mandible in Adult Patients: A Systematic Review.

(1) Background: Chronic non-bacterial osteomyelitis (CNO) is an autoinflammatory bone disease of finally unknown etiology, which can occur alone or related with syndromes (chronic recurrent multifocal osteomyelitis-CRMO; synovitis, acne, pustulosis, hyperostosis and osteitis syndrome-SAPHO). The involvement of the mandible is rather rare. (2) Methods: We carried out a systematic literature search on CNO with mandibular involvement, according to the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) guidelines, considering the different synonyms for CNO, with a special focus on therapy. (3) Results: Finally, only four studies could be included. A total of 36 patients were treated in these studies-therefore, at most, only tendencies could be identified. The therapy in the included works was inconsistent. Various therapies could alleviate the symptoms of the disease. A complete remission could only rarely be observed and is also to be viewed against the background of the fluctuating character of the disease. The success of one-off interventions is unlikely overall, and the need for long-term therapies seems to be indicated. Non-steroidal anti-inflammatory drugs (NSAIDs) were not part of any effective therapy. Surgical therapy should not be the first choice. (4) Conclusions: In summary, no evidence-based therapy recommendation can be given today. For the future, systematic clinical trials on therapy for CNO are desirable.

Radiographic characteristics of chronic diffuse sclerosing osteomyelitis/tendoperiostitis of the mandible: A comparison with chronic suppurative osteomyelitis and osteoradionecrosis.

Diffuse sclerosing osteomyelitis (DSO) of the mandible is a poorly understood chronic disease. It is assumed to be a form of chronic osteomyelitis. Other forms of chronic osteomyelitis are chronic suppurative osteomyelitis (CSO) and osteoradionecrosis (ORN). This study aimed to investigate radiographic characteristics of DSO and compare these findings with the radiographic characteristics of CSO and ORN in order to radiographically distinguish these three diseases. In this retrospective study, 33 patients were clinically diagnosed with DSO (13), CSO (6), or ORN (14). The panoramic radiographs, computed tomography images, and magnetic resonance images of these patients were evaluated. Osseous and soft tissue changes were analysed. Patients with DSO showed extensive cortical and medullary sclerosis combined with subperiosteal bone formation, condylar process deformation, and hypertrophy and oedema of the masseter muscle. DSO patients showed no pathological fractures or sequestra, which were observed in patients with CSO and ORN. The radiographic characteristics that differentiate DSO from CSO and ORN include subperiosteal bone formation, condylar process deformation, masticatory muscle changes, and the absence of sequestra and pathological fractures.

Immunoprecipitation high performance liquid chromatographic analysis of healing process in chronic suppurative osteomyelitis of the jaw.

PURPOSE: Chronic suppurative osteomyelitis (CSO) of the jaw is one of the most difficult infectious diseases to manage, because it causes progressive bony destruction and is associated with bacterial inhabitation of the sequestra. A combination of antibiotic therapy and surgical debridement is often used to treat CSO. Nevertheless, various systemic conditions can lead to life-threatening complications. METHODS: The present study aimed to explore the wound healing progress in 16 cases of CSO through protein expression analysis of postoperative exudates (POE) that were collected 6 h, 1 day, and 2 days after saucerization and/or decortication. A bony lesion was removed during surgery and then examined pathologically, and the CSO POE was examined by immunoprecipitation thus high performance chromatography (IP-HPLC). The POE at 6 h was used as a comparative control. RESULTS: Histologically the CSO lesion showed a necrotic granulomatous lesion heavily infiltrated with polymorphonuclear leukocytes, macrophages, and plasma cells, admixed with multiple sequestra inhabited by bacterial colonies. The IP-HPLC analysis displayed a slight increase in innate immunity-related proteins, i.e., NFkB, TNFα, IL-1, IL-6, IL-28, and LL-37, but a gradual decrease of bacteria-related inflammatory proteins, i.e., IL-8, IL-12, CD31, CD68, and lysozyme. The angiogenesis-related proteins, i.e., VEGF-A and VEGF-C, were slightly decreased but TGF-ß1 and bFGF were markedly increased on day 2. The osteogenesis-related proteins, i.e., OPG and ALP, were slightly increased, while the osteoclastogenesis-related protein, RANKL was slightly decreased compared to the control. CONCLUSION: These findings indicate that the infected CSO undergoes a rapid wound healing process with active osteogenesis and a gradual decrease in bacteria-related inflammation, predicting a favorable prognosis after surgery. Moreover, IP-HPLC can be useful in monitoring the POE and wound healing processes during the postoperative period.

Combination of Girdlestone Pseudoarthroplasty and Negative Pressure Wound Therapy with Instillation and Dwell in the Treatment of Invasive Osteomyelitis of the Proximal Femur.

Osteomyelitis is a progressively destructive invasive infection of the bone that can result in both localized and systemic illness. This includes an acute suppurative infection, generalized weakness, a failure to thrive, a pathological fracture, and non-healing ulcers. When chronic osteomyelitis develops, therapeutic options are limited, as antimicrobial agents cannot penetrate the necrotic bone, and repeated surgical debridement may be needed. Re-establishing full thickness coverage of the wounds and ulcers associated with osteomyelitis is challenging due to factors such as ongoing pressure injury, malnutrition, and resistant microorganisms. Classically, Girdlestone pseudoarthroplasty has been used to manage a resistant and invasive infection of the acetabular cavity and proximal femur, but it is now rarely employed because of the morbidity of removing the femoral head and leaving a wound to heal by secondary intention. Negative pressure wound therapy with instillation and dwell (NPWTi-d) offers a powerful adjunct to the management of complex infections and wound healing. In this case series of invasive osteomyelitis of the proximal femur in non-ambulatory patients, we demonstrate that the combination of the Girdlestone and negative pressure wound therapy with instillation and dwell allows for delayed closure within a week of the initial procedure, with favorable outcomes and no recurrence of osteomyelitis. The case log of a single surgeon was analyzed retrospectively over an 18-month period. The case series includes all patients who underwent the Girdlestone procedure for invasive osteomyelitis of the femoral head after failed antibiotic management, were non-ambulatory, and were greater than age 18. A total of 10 patients with 11 Girdlestone operations were found. Patients were predominantly male. The average age was 40 years. All patients were treated with NPWTi-d and then underwent a delayed primary or partial closure on an average of 4.5 days after the initial debridement. All four patients with no pre-existing pressure ulceration of the greater trochanter underwent primary closure without wound complication. Of the remaining patients with pre-operative ulcers of the greater trochanter, three were closed successfully or completely healed secondarily and four had substantial wound healing and reduction in size in the post-operative time period. All but one patient who had pre-operative ulcers of the ipsilateral ischium also had a noted improvement of ulcer dimensions in the postoperative follow-up period. Two patients developed new pressure ulcers on the contralateral side and two patients had a worsening of their pre-existing contralateral pressure ulcers more than 30 days post-operatively. No patient had a recurrence of their osteomyelitis. During the same time period, one patient refused surgical intervention and died secondary to overwhelming sepsis. Girdlestone pseudoarthroplasty is a radical therapy for refractory invasive osteomyelitis. While it has been historically associated with prolonged or failed wound healing, combining this surgery with negative pressure wound therapy with instillation and dwell allows for the successful eradication of infection. In addition, this facilitates wound healing and closure, providing a powerful alternative to the challenge of refractory invasive osteomyelitis of the hip, an ultimately life-threatening infection.

Chronic Suppurative Osteomyelitis of the Mandible Treated with Antibiotics Complemented with Surgical Treatment: A Case Report / Osteomielitis Crónica Supurativa en Mandíbula Tratada con Antibióticos y Cirugía: Reporte de Caso

ABSTRACT: Osteomyelitis is an infection that affects bone and bone marrow, it occurs due to inoculation of microorganisms either directly or by continuous accumulation through a hematogenous way. Female patient, 64 years old, presenting an increase of volume of the parotid masseteric region and right submandibular region, with approximately two weeks of evolution, which had a slightly fluctuating, hyperemic and hyperthermic indurated consistency; the patient complained of severe pain. CT scan and biopsy was indicated. It is imperative to identify the causative agent; the use of antibiotics must be complemented by surgical treatment to eliminate the possibility of a remaining infection.

RESUMEN: La osteomielitis es un proceso infeccioso que afecta al hueso y medula ósea y que se produce debido a la inoculación de microorganismos ya sea de manera directa, por continuidad o bien por medio de la vía hematógena. Paciente femenino de 64 años de edad que presentaba aumento de volumen en región submandibular derecha refiriendo dolor intenso con evolución de 2 semanas aproximadamente, el cual era de consistencia indurada ligeramente fluctuante, hiperémico e hipertérmico; la paciente se quejaba de dolor intenso, se indicó TC y biopsia. En estos casos para tener éxito en el tratamiento el uso de antibióticos debe complementarse con desbridamiento quirúrgico, aunado a un seguimiento estrecho para descartar la posibilidad de una infección remanente.

Painless Swelling of the Left Jaw in a Two-Year-Old Boy.

We present a case of a 2-year-old boy with chronic suppurative osteomyelitis of the left jaw. A computed tomography (CT) scan demonstrated a periosteal reaction on the left side of the mandible with cortical destruction of the left mandibular head. The diagnosis could be confirmed histologically. During biopsy of the mandibular lesion, a purulent exudate was withdrawn.

Chronic suppurative osteomyelitis of posterior maxilla: A rare presentation.

Thin cortical bone rich in vascularity makes the maxilla scarcely vulnerable to osteomyelitis as compared to mandible. Moreover, the introduction of newer antibiotics, understanding of pathogenesis and improved medical support lead to reduction in incidence of osteomyelitis. Local factors like continuous irritation, smoking and suppressed immune system contributes to the occurrence of suppurative osteomyelitis. We hereby, report an exceptional case of chronic suppurative osteomyelitis of posterior maxilla in a 42-year-old healthy male who was managed successfully by combination of antibiotics, surgical sequestrectomy and debridement.

Chronic suppurative osteomyelitis of maxilla mimicking actinimycotic osteomyelitis: A rare case report.

Osteomyelitis is a disease which is heterogeneous in its pathophysiology, clinical presentation and management. It is considered to be one of the most difficult-to-treat infectious diseases. Progressive bony destruction and the formation of sequestra are hallmarks of osteomyelitis. We hereby report a rare case of maxillary osteomyelitis, which had actinomycotic osteomyelitis like presentation but was histopathologically diagnosed as a severe form of chronic suppurative osteomyelitis.

Chemically induced osteomyelitis in the mandible: A case report

Chronic suppuraive osteomyelitis of the mandible caused by periodontal disease: a case report / 대한치주과학회지

Osteomyelitis is an exhaustive disease whose main feature is an inflammation of inner part of bone, bone marrow. In oral and maxillofacial area, we have maxillary and mandibular osteomyelitis and the latter is dominant because of its impaired blood supply. The main cause of osteomyelitis is a bacterial infection and the ways of infections are by periapical odontogenic infection, fracture, post-operative complication, and periodontal disease. The predominant etiologic factor is periapical odontogenic infection mostly caused by advanced dental caries. It is generally believed that periodontal disease could be a cause of osteomyelitis. But periodontal disease is usually confined to the alveolar bone area and not extends to the underlying bone marrow. Accordingly periodontal infection per se rarely cause produce oseomyelitis. Even though osteomyeltis could be occurred by periodontal disease, its virulence of infection is milder than periapical odontogenic infection. So it usually provokes sclerosing or hyperplastic osteomyelitis rather than suppurative type. We had a case of suppurative osteomyelitis caused by periodontal disease and treated it with periodontal and oral and maxillofacial surgical method.
