Abstract
PURPOSE This paper aims to provide a bibliometric analysis of the maxillofacial reconstruction literature over 40 years and to compare the data with previous studies. METHODS A bibliographical search for oral and maxillofacial surgery literature in maxillofacial reconstruction was conducted on Wef of Science. A graphic representation of authorship and keywords was created with VOSviewer. Mendeley and Microsoft Excel were used for tabulation and data visualization. Some statistical tests were performed with a 95 % confidence interval, which was considered significant. RESULTS A total of 7417 articles from specialized journals were included in the study. These articles received 138,493 citations from 63,390 other studies, with an average citation count of 18.67, and a very high H-index. A total of 2375 specific keywords were analyzed, covering a wide range of topics, with two noteworthy MeSH keywords that have recently gained prominence. A total of 33 journals were included in the study, with a mean Impact Factor of 2.404, indicating a relatively high influence in the subject area. CONCLUSION The high h-index reflects abundant and high-quality literature on maxillofacial reconstruction, with the United States leading in publication quantity. Emerging topics in maxillofacial reconstruction were discussed. These areas shape the discipline, driving advancements and offering opportunities for researchers and clinicians to contribute to progress and improve patient outcomes.

Abstract
AIMS The first aim of this study is to compare and validate the performance of the programmed death receptor ligand 1 (PD-L1) IHC 22C3 pharmDx assay kit processed via Dako Omnis platform with the Dako Autostainer Link 48. The second aim is to examine the concordance of scoring by pathologists using the same immunohistochemistry (IHC) assay on the Dako Omnis platform and the Dako Autostainer Link 48. METHODS Fourty-seven formalin-fixed, paraffin-embedded tissue blocks of head and neck squamous cell carcinoma tumour were stained with the PD-L1 IHC 22C3 pharmDx assay kit processed via the Dako Autostainer Link 48 and the Dako Omnis platform. Combined positive score (CPS) was ascribed by two scoring pathologists, with discordant cases provided with an agreed score. RESULTS First, identical staining patterns were identified. Second, high agreement of PD-L1 scores when a CPS cut-off of 1 was implemented illustrated an overall agreement of 94%, positive agreement of 100% and negative agreement of 88%. Finally, results highlight an intraexaminer concordance of 89% and interexaminer concordance of 85% and 92%. CONCLUSIONS In conclusion, we propose to open for discussion the deconstruction of the current practice of a compulsory companion diagnostic test (CDT) for a particular PD-L1 immunohistochemical assay. The implementation of laboratory developed tests as an alternative to the CDT poses as a novel and readily available method to surmount limitations posed to pathology laboratories.

Abstract
AIMS Current understanding of oral squamous cell carcinoma (OSCC) is incomplete with regard to prognostic factors that lead to the considerable heterogeneity in treatment response and patient outcomes. We aimed to evaluate the impact of individual tumour-infiltrating lymphocyte (TIL) subsets on prognosis as a possible rationale for this, in a retrospective observational study. METHODS Immunohistochemistry was performed to quantitatively assess cell densities of CD3+, CD20+, CD4+, CD8+ and FOXP3+TIL subsets in 50 surgically treated OSCC cases. Results were correlated with disease-free survival (DFS) and overall survival (OS). Receiver operating characteristic curve analysis and Youden index were applied to determine prognostically significant cut-off values. RESULTS Mean counts for CD3+, CD4+, CD8+, CD20+ and FOXP3+TILs were 243, 52, 132, 53 and 116 cells per high power field, respectively. High CD8+ and low FOXP3+TIL counts, and high ratio of CD8:FOXP3 were significantly associated with longer DFS and OS, as well as with improved tumour-host interface parameters. CONCLUSIONS Host immune response and its interaction with cancer cells have a significant impact on OSCC outcomes, with some TIL subsets being more clinically relevant than others. High cytotoxic T-cell (CD8) and low Treg (FOXP3) counts, and high cytotoxic T-cell to Treg (CD8:FOXP3) ratio are significantly associated with favourable prognosis. These results may serve as a leading point in identifying novel therapeutic agents that can redesign the tumour immune microenvironment by reducing infiltrating FOXP3-lymphocytes, and modifying their signalling pathways.

Abstract
AIMS Microbial flora of dental plaque trigger innate and adaptive immune responses. The function of antigen-presenting cells (APCs) is to bridge the innate and adaptive immune systems. The human immune system contains three main types of APCs: dendritic cells (DC) (Langerhans cells (LCs) and interstitial DCs, IDCs), macrophages and B lymphocytes. In this study, the distribution and density of all APCs in healthy and inflamed human gingival tissue were comparatively analysed. METHODS Research was conducted on gingival biopsy specimens obtained from 55 patients and classified in three groups: healthy gingiva (control group, n=10), moderate periodontal disease (PD) (n=21) and severe PD (n=24). For APCs' identification antibodies raised against CD1a (for LCs), S100 protein (for iDCs), CD68 (for macrophages) and CD20 (for B lymphocytes) were used. RESULTS Increased density of IDCs, macrophages and B lymphocytes in lamina propria and reduced density of LCs in the gingival epithelium were found in patients with periodontitis. Simultaneously, it was noticed an increased concentration of macrophages and B cells in the gingival epithelium in patients with PD. No statistically significant difference in the distribution and density of APC was found among patients with moderate and advanced periodontitis. CONCLUSIONS It was hypothesised that in the periodontitis the role of antigen presentation was largely taken from LCs by the DCs, macrophages and B cells. These APCs are thought to have less protective and tolerogenic potential than LCs and this is a significant reason for alveolar bone destruction in periodontitis.

Abstract
OBJECTIVES The aim of this work is to perform a bibliometric analysis on Middle Eastern oral and maxillofacial surgery through years and to compare the data with previous studies. A list of the top 100 most cited articles was generated. METHODS A Pubmed bibliographic search for literature journals specialized in oral and maxillofacial surgery in the Middle East was performed. A graphic representation of authorship and keywords was created with VOSviewer. Mendeley and Microsoft Excel were used for tabulation and data visualization. A list of the top 100 most cited articles was created using Web of Science. Some statistical tests were performed with a 95% confidence interval, which was considered significant. RESULTS A total of 6,536 articles were retrieved in fifteen selected oral and maxillofacial journals. A moderate correlation between number of publications and total population (R = 0.6052), low correlation with area (R = 0.302291), and a negligible correlation with the Human Development Index (HDI) were found (R = 0.1747). A disparity can be seen in the number of publications by country, leaded by Turkey (46.30%), Israel and Iran (13.68% each). The more common studied topic was oral surgery (25.77%), maxillofacial trauma (16.13%) and oral pathology (10.25%). CONCLUSIONS A useful list of the top 100 most cited articles on oral and maxillofacial surgery from Middle East has been created. Middle East publications on oral and maxillofacial surgery can be considered high quality (IF = 1.879). Some issues on performing an adequate selecting of MeSH keywords were discussed.

Abstract
Synovial chondromatosis (SC) in the temporomandibular joint (TMJ) is an uncommon entity, mostly when the involvement is bilateral. The authors report a rare case of bilateral SC, with a follow-up of 13 months, and a literature review. A 60-year-old Caucasian woman, with the chief complaint of pain for 6 years in the bilateral pre-auricular region, had a progressive clacking and discomfort on the left side during mouth opening. The panoramic image was suggestive of SC. The bilateral lesion was surgically removed by direct access. Histopathological examination confirmed the clinical diagnosis of bilateral SC. This article shows the importance of a multidisciplinary approach for the early diagnosis and appropriate treatment. Also, it encourages the referral of such cases to professionals with a greater familiarity with this entity.

Abstract
Leukemic cells are rarely present in the oral cavity, and there are very few reports regarding such cases. However, we identified some reports of leukemic cells infiltrating tissues in the oral cavity, including gingival involvement. Recurrent painful oral ulcerations and prominent generalized periodontal destruction are the most common oral features of neutrophil disorders, and they may even be the initial symptoms of the disease. The ulcers may affect any part of the oral mucosa, including the tongue and palate. The objective of this report is to describe and discuss a case of myeloid sarcoma in the oral cavity of a 48-year-old male patient.

Abstract
Skin lesions are often submitted to oral and maxillofacial pathology practices. The purpose of this study is to evaluate the frequency, distribution, variability, and composition of dermatologic lesions within a large oral and maxillofacial pathology biopsy service. An IRB-approved retrospective search of skin lesions diagnosed at University of Florida oral and maxillofacial pathology biopsy service between 1994 and 2015 was performed. 2487 cases were included in the study. Gender was reported in 2466 cases, of which 59% were male and 41% female. Age was provided in 2367 cases and ranged from 2 weeks to 96 years with an average of 55 years. Location was indicated in 2473 cases. Lips were the most common (41.7%), followed by face (25.3%), neck (7.4%), nose (6.5%), periorbital (5.3%), ear (4.1%), and scalp (3.8%). Of the 2487 cases, five diagnoses (actinic keratosis/cheilitis, intradermal nevus, epidermal inclusion cyst, seborrheic keratosis, and basal cell carcinoma) constituted 84.4% of the cases. 69 of 2487 cases (2.8%) resulted in dermatopathologic consultation prior to final reporting. Skin lesions accounted for ~ 1.0% of all lesions submitted to an oral and maxillofacial pathology biopsy service. This study found a large variation in the dermatologic lesions submitted to an oral pathology biopsy service. Although most were routine in complexity, dermatopathology consultation was an important tool in the diagnosis of the more challenging cases. This study may help pathologists gain a better understanding of the frequency and variability of dermatologic lesions submitted to an oral and maxillofacial pathology biopsy service and promote more interdisciplinary consultation within the field. This study evaluated the incidence and scope of dermatologic lesions submitted to a large oral and maxillofacial pathology biopsy service over a long time period. A wide scope of lesions was found, and dermatopathology consultation was important to quality assurance.

Abstract
Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up.
