Abstract
BACKGROUND Currently, the differentiation of jaw tumors is mainly based on the lesion’s morphology rather than the enhancement characteristics, which are important in the differentiation of neoplasms across the body. There is a paucity of literature on the enhancement characteristics of jaw tumors. This is mainly because, even though computed tomography (CT) is used to evaluate these lesions, they are often imaged without intravenous contrast. This study hypothesised that the enhancement characteristics of the solid component of jaw tumors can aid in the differentiation of these lesions in addition to their morphology by dual-energy CT, therefore improving the ability to differentiate between various pathologies.
AIM To evaluate the role of contrast enhancement and dual-energy quantitative parameters in CT in the differentiation of jaw tumors.
METHODS Fifty-seven patients with jaw tumors underwent contrast-enhanced dual-energy CT. Morphological analysis of the tumor, including the enhancing solid component, was done, followed by quantitative analysis of iodine concentration (IC), water concentration (WC), HU, and normalized IC. The study population was divided into four subgroups based on histopathological analysis-central giant cell granuloma (CGCG), ameloblastoma, odontogenic keratocyst (OKC), and other jaw tumors. A one-way ANOVA test for parametric variables and the Kruskal-Wallis test for non-parametric variables were used. If significant differences were found, a series of independent t-tests or Mann-Whitney U tests were used.
RESULTS Ameloblastoma was the most common pathology (n = 20), followed by CGCG (n = 11) and OKC. CGCG showed a higher mean concentration of all quantitative parameters than ameloblastomas (P < 0.05). An IC threshold of 31.35 × 100 μg/cm3 had the maximum sensitivity (81.8%) and specificity (65%). Between ameloblastomas and OKC, the former showed a higher mean concentration of all quantitative parameters (P < 0.001), however when comparing unilocular ameloblastomas with OKCs, the latter showed significantly higher WC. Also, ameloblastoma had a higher IC and lower WC compared to “other jaw tumors” group.
CONCLUSION Enhancement characteristics of solid components combined with dual-energy parameters offer a more precise way to differentiate between jaw tumors.

Abstract
Intraosseous schwannoma of the mandible is rare, with diagnostic and therapeutic challenges. The aims of this study were to report new cases of intraosseous schwannoma of the mandible and to propose a clinical classification, providing suggestions for treatment methods. The cases of 13 patients treated at the authors' hospital and 86 cases reported previously in the literature were reviewed. The most common clinical feature was facial swelling (60/93). The rate of cortical thinning or expansion was 44.8% (43/96); widening of the inferior alveolar nerve canal on radiographs was observed in 15 patients.

Abstract
This cross-sectional study was performed to examine sources of variation in distress associated with altered appearance and fundamental functions in oral cancer patients at 2 months, 12-15 months, 24-36 months, and ≥ 5 years post-definitive treatment. Eligible patients completed six scales from the FACE-Q Head and Neck Cancer Module. Pre-specified regression models were used to examine sources of variation in study outcomes for 145 patients. Patient self-reports indicated that distress associated with altered appearance and fundamental functions was highly variable, and distress was present beyond 5 years post-definitive treatment in some patients. Associations between distress scores and time post-definitive treatment, reconstructive surgery, and adjuvant therapy were not statistically significant. There was, however, moderate to strong evidence against the null hypothesis of no association between eating distress scores and sex, primary cancer site, and T-stage; smiling distress scores and age and primary cancer site; appearance distress scores and geographical remoteness and primary cancer site; and speaking distress scores and primary cancer site. Primary cancer site was the only significant independent predictor of multiple distress scores. These findings suggest that predicting the psychological impact of oral cancer treatment remains a challenge for the multidisciplinary team. Screening and interventions for psychological distress are essential beyond the preoperative and acute care settings.

Abstract
OBJECTIVE Metastasis to oral and maxillofacial region (MOMFR) is an unusual finding; representing between 1 and 1.5% of all malignancies in the maxillofacial region. A systematic review is presented to determine trends in presentation, diagnostic features, and patient outcome. METHODS Searches of databases were carried out for papers reporting MOMFR. The variables were demographics, patient symptoms, tumor location, tumor size, histopathology, origin of the tumor, immunohistochemical studies, follow-up and survival. RESULTS 696 cases were identified; 391 males, and 305 females. The most common race was white. The most common primary tumor for females was from breast 31.1% (n = 95), for males from lung 20.5% (n = 143). The most common location was the mandible 44.9% (n = 313), followed by gingival soft tissue 16.8% (n = 117). A frequent clinical symptom was pain with 17.5% (n = 122). The most common clinical presentation was a mass or tumor 37.4% (n = 260). The mean age was 58.8 years. The average time before diagnosis was 10.3 months, the mean follow-up after diagnosis was 13.1 months, and the average survival was 9.8 months. CONCLUSION MOMFR shows a strong predilection for the posterior mandible, with a mass or tumor being the most common clinical presentation. They are frequently painful, and demonstrate a poor prognosis.

Abstract
Central giant cell granuloma (CGCG) is a rare lesion of the jaw occurring in young adults and adolescents. Surgery, the traditional mainstay of therapy, is associated with significant morbidity. Denosumab, a humanised monoclonal antibody to RANKL, is effective in a related entity, giant cell tumour of bone (GCTB), but experience in the more indolent CGCG is limited. This prospective observational study of all denosumab-treated CGCG at a tertiary referral centre (2015-2021) aimed to evaluate the safety, efficacy and recurrence risk using denosumab in CGCG at lower-frequency dosing than used for GCTB. All received standardised, time-limited courses of denosumab 120 mg with stepwise increase in dosing interval based on response. They were followed for up to 75 months using a radiation-minimising protocol: 3-monthly clinical, biochemical and radiological assessment (orthopantomograms, cone beam CT). Eight patients, median age 20.5 years [IQR 6], received 13 initial doses [IQR 10] of denosumab 120 mg. Radiologic response was seen after 5.5 doses [IQR 4.5]: ossification in all and size reduction in three. Recurrence occurred in four of seven completing therapy, observed 12 months post-cessation [IQR 6.5]. Larger baseline size, aggressive subtype and fewer than 12 initial doses were more common in the recurrence group. There was no osteonecrosis of the jaw. Hypocalcaemia occurred in one receiving modified dosing. This study represents the largest, most diverse cohort of denosumab-treated CGCG with the longest follow-up in literature. It demonstrates the efficacy of lower-frequency, time-restricted course of denosumab but highlights the risk of recurrence. Long-term follow-up is critical.

Abstract
The purpose of this study was to investigate whether ameloblastoma with a high likelihood of recurrence can be predicted using random forest model, a machine learning algorithm. Data were collected from patients treated for ameloblastoma between 1999 and 2019 at the University of Hong Kong. Fourteen clinical parameters were used to grow the decision trees to classify patients with or without ameloblastoma recurrence in the follow-up period. The random forest algorithm was computed 100 times in the training cohort (n = 100) and verified in the testing cohort (n = 50). The receiver operating characteristic curve (ROC) and area under the curve (AUC) were used as the performance measurement of separability. One hundred and fifty patients (76 female, 74 male) were recruited, with a mean follow-up time of 103 months. Recurrence occurred in a total of 25 cases (16.7%) over the 20-year period. The AUC were calculated for the median and mean ROC curves; these were 0.777 and 0.825, respectively. The results showed that random forest model was able to predict recurrence of ameloblastoma with reliable accuracy. The four most important variables influencing ameloblastoma recurrence were the time elapsed from treatment, initial surgical treatment, tumour size, and radiographic presentation. This study provides insights into the detection of high-risk patient groups to monitor recurrence. Further application of random forest to other diseases could greatly benefit clinical decisions.

Abstract
Chondromyxoid fibroma (CMF) is a benign chondroid/myxoid matrix-producing tumor that often develops in the long bones of young adults. CMF is rarely reported in the craniofacial skeleton, with most cases presenting with bone erosion or destruction, which may lead to a misdiagnosis. To date, approximately 129 cases of CMF in the craniofacial region have been reported, with only three cases in patients aged less than 1 year. Of these 129 cases, only 34 affected the jaws. A 1-year-old boy presented with a mass in the left anterior maxilla, extending and compressing the ipsilateral nasal cavity. After surgical excision of the lesion, microscopy revealed spindle-to-stellate tumor cells surrounded by a predominant myxoid stroma containing focal slit-like vascular channels and hemorrhagic areas. Immunohistochemistry showed positivity for vimentin, CD10, and α-SMA (focal). The Ki-67 labeling index was 6%. CFM should be included in the differential diagnosis when assessing maxillary tumors in pediatric patients.

Abstract
BACKGROUND Primordial odontogenic tumour (POT) is a novel entity that was described in 2014 and that is included in the group of benign mixed epithelial and mesenchymal odontogenic tumours. In recent years, several papers have added new cases with some clinical and histopathological aspects that slightly differ from those described in the original report. The aim of this systematic review is to update all available data on POT published in the literature and to identify those features of the neoplasm that require further investigation. MATERIALS AND METHODS A systematic review of literature was conducted using PubMed, Embase, Web of Science and Scopus. Additional sources were also checked. Publications reporting cases with enough clinicopathological information were included, without any time or language restrictions. Histopathological or radiological studies were considered for qualitative analysis. RESULTS A total of 30 publications were included. Seventeen papers were used for quantitative analysis while 13 papers were used only for qualitative analysis. A total of 18 cases of POT were identified. Some clinical, radiographic, histopathological and therapeutic features were common in all reported cases, while other aspects of the neoplasm were inconsistent through published cases. This inconsistency was particularly remarkable when dealing with the histopathological features of the neoplasm. DISCUSSION Some issues about POT remain unclear and deserve to be clarified by future reports. The description of the odontogenic epithelium covering the ectomesenchyme is often contradictory, while it remains debatable whether peripheral ameloblastic epithelial islands or hard dental tissue deposition can occasionally occur within the tumour.

Abstract
Objectives This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period. Materials and Methods In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed. Results From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases. Conclusion The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.

Abstract
PURPOSE Keratocystic odontogenic tumor (KCOT) is an aggressive benign tumor and the management by complete enucleation followed by cryotherapy maintains the inorganic bone matrix, resulting in better repair and reduces the rates of recurrence. A refrigerant spray with a propane/butane/isobutane gas mixture has been pointed to as an alternative to liquid nitrogen, because the device is easy to handle and contain within the cavity, providing better control and lower risk of injury to the adjacent soft tissue. Thus, the aim of this study was to evaluate the outcome of enucleation followed by cryosurgery using a refrigerant spray of this gas mixture in ten patients diagnosed with KCOT. METHOD The biggest lesions received a prior treatment consisting of marsupialization to decrease the tumor size. During the surgeries, the lesions were removed by enucleation and the surgical site was sprayed with the gas mixture. RESULTS Wound dehiscence was observed in all cases, which healed by the second intention. The mean follow-up period was 64.3 months (range 24-120 months). Eight of the ten patients showed no evidence of clinical or radiographic recurrence. Pathologic fractures and infections were not observed. CONCLUSIONS The results obtained suggest that enucleation followed by cryosurgery is an effective therapy for managing KCOT.

Abstract
Hyperparathyroidism jaw tumour syndrome is a rare autosomal dominant inherited endocrine neoplasia syndrome, which predisposes carriers to develop a triad of multiple ossifying fibromas of the maxilla and mandible, parathyroid adenomas and carcinomas (with consequent hyperparathyroidism) as well as renal and uterine tumours. The prevalence of this condition is unknown. Patients typically present initially with symptoms and signs of a jaw tumour. A high index of suspicion is required for the underlying diagnosis to be recognised, enabling appropriate management of jaw lesions, treatment of hyperparathyroidism, if present, as well as early detection of malignant disease and screening of family members. TEACHING POINTS • HPT-JT is a rare autosomal dominant inherited endocrine neoplasia syndrome. • HPT-JT causes facial disfigurement, morbidity secondary to hyperparathyroidism and malignancy. • Patients can present with ossifying fibromas of the jaw, hypercalcaemia or malignancy. • A high index of suspicion is required for the underlying diagnosis to be recognised. • Management involves screening of family members.

Abstract
BACKGROUND Tumors composed of cells differentiating as both fibroblasts and histiocytes have been designated fibrous histiocytomas. Only a small percentage of these lesions behave in a malignant fashion, they are called malignant fibrous histiocytoma (MFH).The occurrence of MFH in membranous bones including the mandible is quite unusual. Involvement of the mandible accounts for only 3 % of all MFH bone lesions. Recent literature revealed only a few (30) cases of MFH involving the mandible but not a single case of MFH associated with pathological fracture of the mandible, probably the first such kind of case to support antecedent trauma as an initial proliferative response for its occurence. CASE REPORT A rare case of MFH involving the mandible and submandibular glands with pathological fracture in a 14-year-old boy is presented with special emphasis on the poor prognosis even after prompt therapy, its controversial histogenesis, high malignant potential, high recurrence rate and tendency to metastasise. The patient was regularly followed up for 11 months post-operatively, during which patient complained of pain in the operated region after 8 to 9 months. Though there was no clinically obvious abnormality seen, the young boy died after 11 months. The clinical, surgical, radiographic and pathological features of this lesion are discussed. DISCUSSION Malignant fibrous histiocytoma, the most frequent soft tissue sarcoma of adulthood, was first described as a new malignant tumour by O'Brian and Stout in the 1960s and the details of the histopathological features of MFH were first described by Kempson and Kyriakos. Despite the frequency of diagnosis, MFH has remained an enigma as no true cell of origin has ever been identified. Treatment consists of surgical excision and in some cases chemotherapy and radiation. Early and complete surgical removal using wide or radical resection is indicated because of the aggressive nature of the tumor. The combination of infrequent occurrence, varied pathologic features, uncertain histogenesis, numerous subtypes and the many potential sites of presentation makes these tumors a challenge for the diagnostician, surgeon and oncologist. Close follow-up after treatment is important, as local recurrence is common and early metastasis to the lungs is also frequent, which are the reasons for high mortality rate in MFH.

Abstract
The aim of this report is to present a rare case of a child with a desmoplastic fibroma (DF) at the mandibular angle. This lesion commonly shows a radiolucent and radiopaque radiographic picture. Due to its aggressiveness and high recurrence rate, an early diagnosis is essential and the complete removal of the lesion is the treatment of choice. We present a case of 11-year-old boy who was referred to be treated for an growth in the left mandibular angle area, a radiolucent and radiopaque feature. After an incisional biopsy, the complete removal of the lesion was done without vascular or nerve damage of the inferior alveolar bundle and without causing mandibular discontinuity. The clinical and radiographic features suggested the diagnosis and allowed the differentiation of DF from other lesions in the maxillofacial area. However, the final diagnosis was only possible through histopathological examination.
