ABSTRACT
BACKGROUND: Jaw lesions are frequent in the oral and maxillofacial areas. Different methods for enucleating jaw lesions in the oral and maxillofacial sites have been proposed, including the bone lid technique. PURPOSE: The aim of this study was to compare the clinical and radiographic results of the bone lid technique employing a piezoelectric surgery to the traditional technique in individuals with mandibular lesions. MATERIALS AND METHODS: A randomized controlled trial was conducted on 24 patients with mandibular lesions. They were randomly allocated into two groups (n = 12 for each group). Group I: the mandibular lesion was excised with bone lid technique using a piezoelectric device, followed by the fixation of the bony window after its repositioning. Group II: the lesion was excised with the traditional method using rotatory burs. Pain, soft tissue healing, bone exposure, bone lid integration, and the volume of the residual bone defect were all assessed clinically and radiographically after one week, one month, and six months. RESULTS: All patients in both groups showed adequate soft tissue healing except for one case in group I experienced wound dehiscence and bone lid exposure. The bone lid group reported significantly less pain than the usual approach at the 3rd and 7th days. After six months, the volume of bone defect filling was considerably higher in the bone lid group compared to the conventional group. CONCLUSION: The bone lid technique was an effective procedure in the management of mandibular lesions compared to the standard method. Besides, this technique provides better bone healing and reduces bone loss. TRIAL REGISTRATION: This clinical trial was registered at clinicaltrials.gov on 14/8/2023 and had registration number NCT05987930.

OBJECTIVES: This study aims to observe the clinical effect of bone plate reduction in combination with a resorbable plate on large mandibular cysts. METHODS: Between October 2017 and September 2022, patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study. Intraoral approach was performed for bone plate reduction. Cone beam computed tomography (CBCT) scan was reviewed at 3, 6, and 9 months postoperatively to observe postoperative complications. Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure. RESULTS: Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated. The average thickness of the cortical bone on the labial and buccal sides was measured to be about (1.98±0.37) mm before surgery, with a mean value of (0.73±0.17) mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate. The cystic cavities were well revealed during the surgeries, which were completed successfully. Postoperatively, the wounds healed in one stage without infection. The percentages of cyst shrinkage were 20.01%, 41.76%, and 73.41% at 3, 6, and 9 months after surgery, respectively. Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software. The bone mineral densities of the adult bone were 313.78, 555.85, and 657.45 HU at the 3, 6, and 9 month time intervals, respectively. No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale. CONCLUSIONS: Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial region with the presence of cortical bone.

A woman in her 30s presented with a 12-month history of reduced mouth opening and swelling on the right side of her mandible. The swelling was non-tender and firm on palpation. The swelling began to increase in size after the extraction of her carious wisdom tooth. Histopathological and serological examinations confirmed the diagnosis of IgG4-related disease, manifested as a mass in the mandible. The patient was prescribed oral corticosteroids at a tapering dosage over 8 weeks. After 3 months, there was an improvement in the patient's mouth opening and a reduction in the size of the swelling. The patient remains in follow-up care. Including IgG4-related disease in the list of potential diagnoses for oral soft tissue masses is crucial, given their positive response to medical treatment, highlighting the significance of an accurate diagnosis to prevent unnecessary surgery, with oral lesions potentially serving as early indicators before multiorgan complications arise.

BACKGROUND: Magnetic resonance imaging (MRI) of the brain is frequently performed on patients with neurofibromatosis type 1 (NF1), to detect and follow-up intracranial findings. In addition, NF1-related pathologies can appear in the jaws. This case study investigates if it is advantageous to assess the depicted parts of the jaws in the imaging of NF1 patients with intracranial findings, thereby detecting jaw pathologies in their initial stages. CASE PRESENTATION: We report on the 3-year management with clinical and radiological follow-ups of a central giant cell granuloma and a neurofibroma in the mandible of a patient with NF1 who underwent examinations with brain MRIs. A review of the mandible in the patient's MRIs disclosed lesions with clear differences in progression rates. CONCLUSION: NF1-related jaw pathologies may be detected in the early stages if the depicted parts of the jaws are included in the assessment of the imaging of NF1 patients with intracranial findings. This could impact the treatment of eventual pathologies before lesion progression and further damage to the vicinity.

Chronic diffuse sclerosing osteomyelitis is a very rare condition, described as a non-suppurative, inflammatory disease of the bone and characterized by a proliferative endosteal reaction, which clinically reveals itself with cyclic pain of the jaw and swelling. We reported two clinical cases, where patients suffered recurrent swelling and pain at the mandible irradiating to the preauricular area, denying any previous trauma or significant medical history. Odontogenic causes were excluded. An initial treatment with antibiotics and NSAIDs temporarily relieved the symptoms without complete resolution, prompting further investigations. After a comprehensive array of diagnostic tools (X-rays, CT scans, scintigraphy, bone biopsy, serum markers), both patients were diagnosed with chronic diffuse sclerosing osteomyelitis of the mandible. Bisphosphonates (clodronate and zolendronate) with different treatment schemes were used to treat the condition, until a full recovery from symptoms was reported. Bisphosphonates could therefore represent an effective option in managing this rare but impactful condition. Further research is warranted to better understand the underlying mechanisms of the disease and to optimize treatment strategies.

Aneurysmal bone cyst is a rare osteolytic lesion of uncertain etiology, commonly observed in the lower limbs, with only 1-2% of reports in gnathic bones. We present the case of a 27-year-old male patient referred to the oral and maxillofacial surgery and traumatology service due to complaints of paresthesia in the mental region and increased mandibular volume. Physical examination revealed midline shift and hard consistency. Imaging examinations demonstrated a radiolucent/hypodense lesion with disruption of the mandibular cortices. The histopathological examination of incisional biopsy material led to the diagnosis of a central giant cell lesion. The patient underwent surgical resection, and the histopathological analysis of the specimen revealed a predominantly solid lesion, characterized by blood-filled spaces of varying size, not covered by epithelium or endothelium, with the presence of spindle cells, multinucleated giant cells, and basophilic osteoid material, concluding the diagnosis of mixed-type aneurysmal bone cyst. Despite being uncommon, aneurysmal bone cysts should be considered in the differential diagnosis of volumetric increase in the gnathic bones of young patients.

OBJECTIVE: This study evaluated the effectiveness of a submental island flap in closing advanced mandibular medication-related osteonecrosis of the jaw (MRONJ) wounds in patients with malignant tumors. SUBJECTS AND METHODS: A total of 85 patients with stage II and III MRONJ of mandible with malignant tumor as their primary disease were retrospectively analyzed. All patients underwent surgical treatment, and the soft tissue wound closure was performed either with a submental island flap (SIF) or mucoperiosteal flap (MF). Univariate and multifactorial models were applied to analyze the factors influencing patients' prognosis. RESULTS: Univariate analysis (p = 0.004, OR 0.075-0.575, 95% CI) and binary logistic regression (p = 0.017, OR 0.032-0.713, 95% CI) suggested that the surgical prognosis of SIF wound closure was significantly better than that of MF. CONCLUSION: Closure of wound after resection of mandibular MRONJ lesions in patients with malignant tumors using SIF had a better clinical prognosis compared with MF.

Our study aimed to estimate the prevalence of total free flap failure following free flap reconstruction for mandibular osteoradionecrosis (mORN) and assess the impact of potential moderators on this outcome. A comprehensive systematic literature search was independently conducted by two reviewers using the Medline, Scopus, Web of Science and Cochrane Library databases. Quality assessment of the selected studies was performed, and prevalence estimates with 95% confidence intervals (CI) were calculated. Outlier and influential analyses were conducted, and meta-regression analyses was employed to investigate the effects of continuous variables on the estimated prevalence. Ultimately, forty-six eligible studies (involving 1292 participants and 1344 free flaps) were included in our meta-analysis. The findings of our study revealed a prevalence of 3.1% (95% CI 1.3-5.4%) for total free flap failure after reconstruction for mORN. No study was identified as critically influential, and meta-regression analysis did not pinpoint any potential sources of heterogeneity. These findings provide valuable insights for researchers and serve as a foundation for future investigations into the management of mandibular osteoradionecrosis and the prevention of free flap failure in this context.

BACKGROUND: A xanthoma is a rare bone condition consisting of a predominant collection of lipid-rich, foamy histiocytes. The central xanthoma of the jaws is a unique benign tumor. CASE REPORT: A 15-year-old Caucasian male has been presented to our department. He had radiological changes in the area of the left mandibular angle, with an area of diffuse osteolysis of 3.0 cm by 2.0 cm. Computed tomography reveals an area of diffuse osteolysis that starts from the distal root of the lower second molar and reaches the ascending process. A bone biopsy was performed, which revealed a benign proliferative process composed of histiocytic cells involving and infiltrating trabecular bone in a background of loose fibrous connective tissue devoid of any other significant inflammatory infiltrate. The size of the formation was 2.9 cm by 2.0 cm. Immunohistochemical staining for CD68 was strongly positive and negative for S-100 and CD1a. From routine blood tests, cholesterol, triglycerides, and blood sugar are within normal values, which excludes systemic metabolic disease. Subsequent to the surgical intervention, the patient underwent postoperative assessments at intervals of 14, 30, 60 days, and a year later, revealing the absence of any discernible complications during the aforementioned observation periods. CONCLUSION: The diagnosis of primary xanthoma of the mandible is rare and can often be confused with other histiocytic lesions. A differential diagnosis should be made with nonossifying fibroma and Langerhans cell histiocytosis, as in our case. In these cases, immunohistochemistry with CD 68, S-100, and CD1a, as well as blood parameters, are crucial for the diagnosis.

Extranodal natural killer/T-cell lymphoma is a distinct subtype of non-Hodgkin lymphoma that originates from natural killer cells or cytotoxic T cells. Its diagnosis is challenging due to the rarity and lack of awareness, especially in cases where osteomyelitis of the jawbone is the initial symptom. This paper reports a case of extranodal natural killer/T-cell lymphoma presenting primarily with oral ulcers. Through analyzing the clinical and pathological characteristics, differential diagnosis, treatment and prognosis, and reasons for misdiagnosis of the disease, this study aims to provide references for clinical diagnosis and treatment.

BACKGROUND: Solitary Bone Cyst (SBC), also known as a simple bone cyst, hemorrhagic cyst, or traumatic cyst is classified by the WHO among non-odontogenic benign lesions of the jaw. The article explores the use of a static 3D-printed surgical guide to treat mandibular SBC, emphasizing a minimally surgical approach for this lesion. CASE PRESENTATION: A 20-year-old woman was referred for a persistent mandibular SBC lacuna, without specific complaints. Her medical history included a previous bone trepanation for a SBC in the same area, radiologically and surgically confirmed. X-ray assessment showed a well-defined unilocular radiolucency surrounding the root of the first left lower molar (tooth #36), measuring 10 × 10 mm. Pulp sensitivity was normal. CBCT data and STL files of dental cast were obtained preoperatively and registered. A 3D-printed surgical guide was used for minimally invasive trepanation of the buccal cortical. The simulation used a targeted endodontic microsurgery approach in order to determine axis and diameter of the trephine. Surgery was performed under local anesthesia. The guide was tooth supported integrating tubes and a fork for guiding precise trepanation. A 3.5 mm round bone window was created, leaving an empty cavity confirming SBC diagnosis and permitting bone curettage. A blood clot was obtained to promote bone healing. Complete reossification was observed after 6 months. The follow-up at 2 years confirmed a complete bone healing with normal pulp sensitivity. DISCUSSION: The 3D-printed windowed surgical guide with dental support offers big advantages, including improved visibility and reduced errors. Compared to traditional guides, it eliminates visual hindrance and allows easier and quick access to confined areas as well as an improved irrigation during drilling process. The article also highlights the importance of preoperative planning while acknowledging potential limitations and errors and surgical complications. CONCLUSION: The use of the 3D-printed surgical guide could be used in routine for minimally invasive intervention of SBC. This case also demonstrates the potential utility of this approach in various procedures in oral and maxillofacial surgery. The technique provides precise localization, reducing complications and enhances operative efficiency.

BACKGROUND: A central giant cell granuloma (CGCG) is a benign, proliferative, intraosseous, and non-odontogenic lesion occurring primarily in children and young adults. On the histological level, it is characterized by numerous multinucleated giant cells scattered randomly throughout a sea of spindle-shaped mesenchymal stromal cells which are dispersed throughout the fibrovascular connective tissue stroma containing areas of haemorrhage. When it comes to radiographic features, CGCG can have an array of variations, ranging from well-defined expansile lesions to ill-defined and destructive lesions, with or without expansion. CASE PRESENTATION: This case report reviews an 11-year-old Caucasian patient with a chief complaint of slow-growing swelling involving the right posterior mandibular region. The cone beam computed tomography (CBCT) revealed an ill-defined mixed lesion mimicking both fibro-osseous lesion and hemangioma. However, microscopic examination revealed multinucleated giant cells in a fibrous stroma suggestive of central giant cell granuloma. CONCLUSION: Our intent in reporting this case is to highlight the importance of thorough clinical, radiographical and histopathological examination for accurate diagnosis and therapeutic interventions as well as to emphasize the importance of taking different possibilities into consideration when examining bony swellings in the head and neck region.

OBJECTIVE: Idiopathic condylar resorption (ICR), also known as progressive condylar resorption, is poorly understood, particularly in adolescent patients. Therefore, this scoping review aims to summarize the available literature on the prevalence, aetiology, pathogenesis, diagnostic process, treatment and/or any outcome regarding ICR in adolescent individuals. METHODS: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and its extension for scoping reviews (PRISMA-ScR), as well as Joanna Briggs Institute studies. The search strategy was defined adopting a core search structure for each source, and the search was performed on MEDLINE, EMBASE, Cochrane Library, Web of Science, Scopus and Google Scholar. After duplicate removal, two independent reviewers screened abstracts, followed by complete articles, to achieve the definition of included studies. Data collection was performed, and the extracted data were organized in tabular form, along with a narrative summary of main findings that aligns with the objective of this review. RESULTS: Six observational studies were included in this review. Three studies focused on signs and symptoms, one on prevalence and signs and symptoms, one on treatment and one on disease pathogenesis. CONCLUSION: This scoping review revealed inadequate published research regarding prevalence, aetiology, early diagnosis, pathogenesis and treatment of ICR in adolescents.

This study investigated the natural course of cemento-osseous dysplasia (COD) on cone-beam computed tomography (CBCT). Retrospectively, 104 CBCT scans from 36 patients (mean age, 44.5 years; 33 female and three male) with mandibular COD (10 florid, seven focal, 19 periapical) were included, based upon clinico-radiological features, without complications such as infection and related surgery. Changes in maximum diameter and morphology (lytic, mixed lytic-sclerotic, sclerotic) were evaluated in 83 lesions, with a mean follow-up of 28.3 months. The occurrence of a diameter increase was assessed by time-to-event analysis; interreader agreement for diameter and morphological evaluation by intraclass correlation coefficient and weighted κ statistics, respectively. Fifteen of 83 (18.1%) lesions (eight florid, one focal, six periapical) in 10 patients increased in diameter; 12 of 83 (14.5%) lesions (five florid, seven periapical) in 11 patients changed morphologically. The median period until a diameter increase was longest (120 months) for periapical COD, and shortest (66 months) for florid COD (p = 0.023). There was high reader agreement (ICC = 0.891; weighted κ = 0.901). In conclusion, CBCT is an effective tool with which to follow-up COD. If any, the natural progress in uncomplicated COD is prolonged, which underlines its non-surgical character and aids in its long-term management.

STUDY DESIGN: Case report. Osteoradionecrosis (ORN) of the jaw is a potentially devastating consequence of head and neck irradiation. The progression of ORN can lead to loss of bone, teeth, soft tissue necrosis, pathologic fracture, and oro-cutaneous fistula. Reconstructive surgery has mostly been reserved for late-stage disease where segmental resections are frequently necessary. Evidence is emerging to support earlier treatment in the form of debridement in combination with soft tissue free flaps for intermediate-stage ORN. The authors present a case of a 76-year-old male with persistent Notani 2 ORN of the mandible, treated with surgical removal of all remaining mandibular teeth, transoral debridement of all necrotic mandibular bone, and bone coverage with a left medial femoral condyle (MFC) periosteal free flap based on the descending genicular artery. Treatment was uneventful both intraoperatively and postoperatively. Since surgery (15 mo) the patient has remained free from clinical and radiologic signs of ORN. The MFP periosteal free flap provided an excellent result with minimal surgical complexity and morbidity in this case. Such treatment at an intermediate stage likely results in a reduction in segmental resections, less donor site morbidity, less operative time, less overall treatment time, and possibly fewer postoperative complications compared with the status quo.

Central and peripheral giant cell granulomas are benign entities mostly seen in mandibular anterior region at female individuals, usually with observed recurrence. Their etiology is still unclear, as is the optimal method for treating them. The aim of this study was to evaluate the incidence, treatment methods, recurrence rates, and initial and definitive correlation of central and peripheral giant cell granulomas. Patients who were referred to our clinic between 2013 and 2023 and who had the lesions' definitive diagnosis as "central giant cell granuloma" (CGCG) or "peripheral giant cell granuloma" (PGCG) were included in the study. Demographic data, recurrence rates, treatment methods, lesion location, clinical behaviors, and sizes were noted on the reports. A total of 30 lesions in 23 patients (14 PGCG and 9 CGCG) were evaluated in this study. The mean follow-up time was 62.6 months; 8 of 23 patients had systemic disease. While only 1 patient was observed to have cortical bone destruction in PCGC, all patients were found to have cortical bone destruction in CGCG (p < 0.05). In both lesions, the correlation of preliminary and definitive diagnosis was evaluated, and it was found to be 50% in PGCG while it was 77.7% in CGCG. The recurrence rates were 21.4% in PGCG and 33.3% in CGCG. Curettage was applied in all patients. Additional treatments (intralesional steroid injections, denasumab applications, resection, and graft application) were performed in 5 patients who were found to have CGCG (p = 0.004). However, there was no significant relation between treatment method and recurrence in CGCG (p > 0.05). Various peripheral lesions could mimic PGCG; thus, curettage therapy could be appropriate in the treatment of PGCG. Nevertheless, in some cases of CGCG, additional treatment methods could be more effective for preventing recurrence and any other complications.

This paper outlines a 10-patient case series of chronic non-bacterial osteomyelitis (CNO) of the mandible at a tertiary paediatric hospital in the UK. Our findings highlight the homogeneous presenting signs and symptoms of an intermittently painful, swollen angle and ramus of the mandible. We present the typical laboratory investigative findings (normal inflammatory markers) and imaging appearances (sclerosis and periosteal oedema). Our paper outlines an investigation protocol, including recommendations for extraoral bone biopsies and systemic magnetic resonance imaging (MRI). We explain the importance of multidisciplinary care, with combined care by rheumatologists and infectious disease specialists. Finally we demonstrate the efficacy of our treatment algorithm for oral non-steroidal anti-inflammatory drugs (NSAIDs), and in those cases refractory to NSAIDS, intravenous pamidronate. This paper provides a useful addition to the literature by informing OMF surgeons of this rare condition and given the clinical equipoise in treatments, it can hopefully guide clinicians in an investigation pathway and management protocol.

Stafne bone defect (SBD) is a rare developmental bone defect characterized by an asymptomatic focal concavity of the cortical bone, typically on the lingual aspect of the mandibular body, which generally contains salivary gland tissue. It can be detected during routine dental examinations and typically appears as an ovoid, well-defined, well-corticated, radiolucent depression in the posterior mandibular region below the inferior alveolar nerve (IAN) (in: Neville et al, Oral and maxillofacial pathology, Elsevier, Inc, St. Louis, MO, 2016).An 80-year-old male presented to our clinic for a routine dental examination. Panoramic radiography and cone-beam computed tomography (CBCT) displayed two well-defined, well-corticated, ovoid radiolucencies inferior to the IAN canal on the left mandibular molar region. The working diagnosis was SBD, and the patient was informed of the findings. Irregular margins on the superior aspect of the anterior defect were noted on CBCT imaging; therefore, follow-up with panoramic images at 6 months, 1 and 5 years was recommended.
