Abstract
Bone defects resulting from trauma, diseases, or surgical procedures pose significant challenges in the field of oral and maxillofacial surgery. The development of effective bone substitute materials that promote bone healing and regeneration is crucial for successful clinical outcomes. Calcium phosphate cements (CPCs) have emerged as promising candidates for bone replacement due to their biocompatibility, bioactivity, and ability to integrate with host tissues. However, there is a continuous demand for further improvements in the mechanical properties, biodegradability, and bioactivity of these materials. Dual setting of cements is one way to improve the performance of CPCs. Therefore, silicate matrices can be incorporated in these cements. Silicate-based materials have shown great potential in various biomedical applications, including tissue engineering and drug delivery systems. In the context of bone regeneration, silicate matrices offer unique advantages such as improved mechanical stability, controlled release of bioactive ions, and enhanced cellular responses. Comprehensive assessments of both the material properties and biological responses of our samples were conducted. Cytocompatibility was assessed through in vitro testing using osteoblastic (MG-63) and osteoclastic (RAW 264.7) cell lines. Cell activity on the surfaces was quantified, and scanning electron microscopy (SEM) was employed to capture images of the RAW cells. In our study, incorporation of tetraethyl orthosilicate (TEOS) in dual-curing cements significantly enhanced physical properties, attributed to increased crosslinking density and reduced pore size. Higher alkoxysilyl group concentration improved biocompatibility by facilitating greater crosslinking. Additionally, our findings suggest citrate's potential as an alternative retarder due to its positive interaction with the silicate matrix, offering insights for future dental material research. This paper aims to provide an overview of the importance of silicate matrices as modifiers for calcium phosphate cements, focusing on their impact on the mechanical properties, setting behaviour, and biocompatibility of the resulting composites.

Abstract
BACKGROUND In this case series, a perioperative anticoagulation protocol for microvascular head and neck surgery in patients with thrombophilia is presented. Microvascular free-flap surgery is a standard procedure in head and neck surgery with high success rates. Nevertheless, flap loss-which is most often caused by thrombosis-can occur and has far-reaching consequences, such as functional impairment, prolonged hospitalization, and increased costs. The risk of flap loss owing to thrombosis is significantly increased in patients with thrombophilia. Therefore, perioperative anticoagulation is mandatory. To date, no perioperative anticoagulation protocol exists for these high-risk patients. CASE PRESENTATION We present three exemplary male Caucasian patients aged 53-57 years with free flap loss owing to an underlying, hidden thrombophilia. CONCLUSION We present a modified anticoagulation protocol for microvascular surgery in these high-risk patients, enabling successful microsurgical reconstruction.

Abstract
Background Globally, head and neck squamous cell carcinoma (HNSCC) is the seventh most common malignancy. Despite aggressive multimodal treatment approaches, recurrent and/or metastatic (R/M) disease develops in >50% of patients. In this setting, pembrolizumab was approved for patients with PD-L1 expression. However, response rates with checkpoint inhibitor monotherapy remain limited and strategies to strengthen tumor-directed immune responses are needed. Objective The FOCUS trial is designed to estimate the effectiveness of UV1 vaccination in combination with pembrolizumab versus pembrolizumab as a single agent in patients with R/M HNSCC. Methods and analysis The FOCUS trial is a two-armed, randomized, multicenter phase II study which was designed to evaluate the efficacy and feasibility of the hTERT-targeted cancer vaccine UV1 as add-on to pembrolizumab in the 1st line treatment of patients with R/M PD-L1 positive (combined positive score ≥1) HNSCC. Secondary objectives are the exploration of patient subgroups most likely deriving benefit from this novel combination and the establishment of liquid biopsy tumor monitoring in HNSCC. Ethics and dissemination This clinical study was designed and will be conducted in compliance with Good Clinical Practice and in accordance with the Declaration of Helsinki. It is intended to publish the results of this study in peer-reviewed scientific journals and to present its content at academic conferences. Conclusions A significant number of patients with R/M HNSCC are frail and may not tolerate chemotherapy, these patients may only be suitable for pembrolizumab monotherapy. However, long term disease stabilizations remain the exception and there is a need for the development of efficacious combination regimens for this patient population. The FOCUS study aims to optimize treatment of R/M HNSCC patients with this promising new treatment approach.

Abstract
BACKGROUND This study investigated whether patient-specific condylar positioning devices (CPDs) are beneficial compared to the conventional manual positioning of the condyles. METHODS In this prospective, randomized trial, patients undergoing orthognathic surgery with a bilateral sagittal split osteotomy of the mandible were included. The ascending ramus was positioned with computer-aided designed and computer-aided manufactured (CAD/CAM) patient-specific devices in the CPD group and manually in the control group. Postoperatively, cone-beam computed tomography (CBCT) was performed to align the virtually planned position with the postoperative result. RESULTS Thirty patients were enrolled in the study, with 14 randomized to the CPD group and 16 to the control group. In the CPD group, the ascending ramus differed in the postoperative CBCT scan from the virtually planned position by 0.8 mm in the left/right, 0.8 mm in the front/back, and 1.3 mm in the cranial/caudal direction. The corresponding control-group values were 1.1 mm, 1.3 mm, and 1.6 mm. CPD and controls differed significantly for the left/right movement of the rami (p = 0.04) but not for the other directions or rotations (p > 0.05). CONCLUSIONS The results demonstrate that both methods are accurate, and postoperative results matched the virtually planned position precisely. It can be assumed that the described CPDs are beneficial when a condylar position different from the preoperative is desired.

Abstract
To define frailty in older cancer patients, the aim of this study was to assess the geriatric status and quality of life (QoL) aspects in patients suffering from recurrent/metastatic head and neck squamous cell carcinoma (r/m HNSCC) under palliative treatment. A comprehensive geriatric assessment (CGA) was performed on 21 r/m HNSCC patients at two defined assessments, and the QoL aspects and the impact of descriptive data were evaluated. The Kolmogorov-Smirnov test, Spearman's rho correlation, and two-way mixed ANOVA were used for statistical analysis. All patients were found to be "frail". Pain, fatigue, and the burden of illness were the highest-rated symptoms. Oral function and orofacial appearance were highly impaired. A significant impact of descriptive data on the CGA and QoL results was found (all p ≤ 0.05). Thus, the CGA results revealed high frailty, severe comorbidities, and high impairments in QoL aspects. The CGA and QoL results were negatively affected by the primary HNSCC treatment approach, the need for prosthetic treatment, and worse oral functional capacity. Therefore, frailty in r/m HNSCC patients seems to be multidimensional. The evaluation of the CGA and QoL aspects in r/m HNSCC patients can be recommended to detect special needs, organize aftercare, and improve the support for frail and vulnerable cancer patients to create a multidisciplinary treatment approach.

Abstract
PURPOSE CheckMate 651 (ClinicalTrials.gov identifier: NCT02741570) evaluated first-line nivolumab plus ipilimumab versus EXTREME (cetuximab plus cisplatin/carboplatin plus fluorouracil ≤ six cycles, then cetuximab maintenance) in recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). METHODS Patients without prior systemic therapy for R/M SCCHN were randomly assigned 1:1 to nivolumab plus ipilimumab or EXTREME. Primary end points were overall survival (OS) in the all randomly assigned and programmed death-ligand 1 combined positive score (CPS) ≥ 20 populations. Secondary end points included OS in the programmed death-ligand 1 CPS ≥ 1 population, and progression-free survival, objective response rate, and duration of response in the all randomly assigned and CPS ≥ 20 populations. RESULTS Among 947 patients randomly assigned, 38.3% had CPS ≥ 20. There were no statistically significant differences in OS with nivolumab plus ipilimumab versus EXTREME in the all randomly assigned (median: 13.9 v 13.5 months; hazard ratio [HR], 0.95; 97.9% CI, 0.80 to 1.13; P = .4951) and CPS ≥ 20 (median: 17.6 v 14.6 months; HR, 0.78; 97.51% CI, 0.59 to 1.03; P = .0469) populations. In patients with CPS ≥ 1, the median OS was 15.7 versus 13.2 months (HR, 0.82; 95% CI, 0.69 to 0.97). Among patients with CPS ≥ 20, the median progression-free survival was 5.4 months (nivolumab plus ipilimumab) versus 7.0 months (EXTREME), objective response rate was 34.1% versus 36.0%, and median duration of response was 32.6 versus 7.0 months. Grade 3/4 treatment-related adverse events occurred in 28.2% of patients treated with nivolumab plus ipilimumab versus 70.7% treated with EXTREME. CONCLUSION CheckMate 651 did not meet its primary end points of OS in the all randomly assigned or CPS ≥ 20 populations. Nivolumab plus ipilimumab showed a favorable safety profile compared with EXTREME. There continues to be a need for new therapies in patients with R/M SCCHN.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous group of cancers and patients have limited therapy options if primary treatment fails. Therefore, additional information about the biology of the tumor is essential. Here we performed a feasibility study of concurrently applying two precision diagnostic tools in a consecutive series of HNSCC patients. We analyzed tumor samples of 31 patients using a genomic (oncomine) and a proteomic, immunohistochemical approach (oncopanel) and compared the result, also in the focus on their overlapping therapeutical targets. We found no strong correlation between the two approaches and observed a higher proportion of marker expression for the immunohistochemical panel. However, both panels show in our HNSCC cohort distinct patterns with druggable targets. The data suggest that both approaches complement one another and can be applied side-by-side to identify the best targets for the development of individual treatment options for HNSCC patients.

Abstract
Mammary analogue secretory carcinoma (MASC) is a rare malignant tumour of the salivary glands, with only few cases reported in the literature to date. Initial preoperative staging is crucial for all patients with an oral malignancy to visualize the tumour, detect lymph node or distant metastases and plan therapeutic interventions. In the case presented herein, radiological imaging revealed a tumour of the right hard palate with suspected positive contralateral lymph nodes. Therefore, local tumour resection comprising hemimaxillectomy and bilateral neck dissection was performed. The diagnosis of MASC was finally based on characteristic histopathological and immunohistochemical findings, such as S100 protein and mammaglobin positivity. The diagnosis of MASC may be challenging, as such findings lack specificity. To confirm the diagnosis, molecular genetic examinations may be performed to detect a highly specific ETV6-NTRK3 fusion gene. Depending on the results of these examinations, surgery, alone or combined with adjuvant radiation or chemoradiation, is the recommended approach. In summary, MASC should be treated similarly to other low-grade salivary gland tumours, such as acinic cell carcinoma, as they exhibit biological and histopathological similarities.

Abstract
IMPORTANCE Squamous cell carcinoma (SCC) of the oral cavity is one of the most common tumor entities worldwide. Precise initial staging is necessary to determine a diagnosis, treatment, and prognosis. OBJECTIVE To examine the diagnostic accuracy of preoperative 18-F fluorodeoxyglucose (FDG) positron emission tomographic/computed tomographic (PET/CT) imaging in detecting cervical lymph node metastases. DESIGN, SETTING, AND PARTICIPANTS This prospective diagnostic study was performed at a single tertiary reference center between June 1, 2013, and January 31, 2016. Data were analyzed from April 7, 2018, through May 31, 2019. Observers of the FDG PET/CT imaging were blinded to patients' tumor stage. A total of 150 treatment-naive patients with clinical suspicion of SCC of the oral cavity were enrolled. EXPOSURES All patients underwent FDG PET/CT imaging before local tumor resection with selective or complete neck dissection. MAIN OUTCOMES AND MEASURES The accuracy of FDG PET/CT in localizing primary tumor, lymph node, and distant metastases was tested. Histopathologic characteristics of the tissue samples served as the standard of reference. RESULTS Of the 150 patients enrolled, 135 patients (74 [54.8%] men) with a median age of 63 years (range, 23-88 years) met the inclusion criteria (histopathologically confirmed primary SCC of the oral cavity/level-based histopathologic assessment of the resected lymph nodes). Thirty-six patients (26.7%) in the study cohort had neck metastases. Use of FDG PET/CT detected cervical lymph node metastasis with 83.3% sensitivity (95% CI, 71.2%-95.5%) and 84.8% specificity (95% CI, 77.8%-91.9%) and had a negative predictive value of 93.3% (95% CI, 88.2%-98.5%). The specificity was higher than for contrast-enhanced cervical CT imaging (67.0%; 95% CI, 57.4%-76.7%; P < .01) and cervical magnetic resonance imaging (62.6%; 95% CI, 52.7%-72.6%; P < .001). Ipsilateral lymph node metastasis in left- or right-sided primary tumor sites was detected with 78.6% sensitivity (95% CI, 63.4%-93.8%) and 83.1% specificity (95% CI, 75.1%-91.2%), and contralateral metastatic involvement was detected with 66.7% sensitivity (95% CI, 28.9%-100.0%) and 98.6% specificity (95% CI, 95.9%-100.0%). No distant metastases were observed. CONCLUSIONS AND RELEVANCE In this study, FDG PET/CT imaging had a high negative predictive value in detecting cervical lymph node metastasis in patients with newly diagnosed, treatment-naive SCC of the oral cavity. Routine clinical use of FDG PET/CT might lead to a substantial reduction of treatment-related morbidity in most patients.

Abstract
Merkel cell carcinoma (MCC, ICD-O M8247 / 3) is a rare malignant primary skin tumor with epithelial and neuroendocrine differentiation. The neoplastic cells share many morphological, immunohistochemical and ultrastructural characteristics with Merkel cells of the skin. The diagnosis of MCC is rarely made on clinical grounds. Histological and immunohistochemical studies are usually required to confirm the clinical suspicion. Given the frequent occurrence of occult lymph node metastasis, sentinel lymph node biopsy should be performed once distant metastasis has been ruled out by cross-sectional imaging. Primary tumors without evidence of organ metastases are treated with complete surgical excision with appropriate surgical margins. Radiation therapy should be considered at all stages of the disease. For advanced MCC that is no longer amenable to curative treatment by surgery or radiation therapy, there is currently no established systemic therapy for which an improvement in recurrence-free survival or overall survival has been demonstrated in a prospective randomized trial. However, immunotherapy using PD-1/PD-L1 blockade seems to be superior to chemotherapy. Various factors warrant that further diagnostic and therapeutic interventions be determined by an interdisciplinary tumor board. These factors include the tumor's aggressiveness, the frequent indication for sentinel lymph node biopsy along with the frequent occurrence in the head and neck region, the potential indication for adjuvant radiation therapy as well as the complexity of the required diagnostic workup.

Abstract
BACKGROUND AND OBJECTIVES The aim of the present study was to assess the prevalence of medication-related osteonecrosis of the jaw (MRONJ) in osteoporosis patients suffering from inflammatory rheumatic diseases, as well as to assess the prevalence of relevant dental, behavioral, and medical risk factors for MRONJ. MATERIALS AND METHODS A total of 198 patients with inflammatory rheumatic diseases and osteoporosis therapy were recruited from a tertiary rheumatological/immunological referral center between June 2015 and September 2016. They were assessed using a structured interview. A maxillofacial surgeon later examined patients complaining of possible symptoms of osteonecrosis. In cases of osteonecrosis, dental records were obtained and evaluated. Preventive measures taken and dental as well as other clinical risk factors were evaluated. RESULTS Of the 198 patients, three suffered from osteonecrosis of the jaw, none of whom had any history of malignant disease or radiation therapy, resulting in a prevalence of 1.5%. Of these three patients, only one was given bisphosphonates intravenously (i.v.), whereas all three had been treated orally. All three diagnoses of MRONJ had been previously known to the patients and their maxillofacial surgeons. Two of the patients had rheumatoid arthritis, and one patient suffered from large vessel vasculitis. Long anti-osteoporotic treatment duration, low functional status, and low bone density of the femur were significantly associated with MRONJ development. CONCLUSION Inflammatory rheumatic diseases constitute a risk factor for MRONJ in patients treated with bisphosphonates for osteoporosis. Patients should be counseled accordingly and should be offered dental screening and regular dental check-ups.

Abstract
Up to 80% of patients with head and neck cancers are malnourished because of their lifestyle and the risk factors associated with this disease. Unfortunately, nutrition management systems are not implemented in most head and neck cancer clinics. Even worse, many head and neck surgeons as well as hospital management authorities disregard the importance of nutrition management in head and neck cancer patients. In addition, the often extensive resection and reconstruction required for tumors in the upper aerodigestive tract pose special challenges for swallowing and sufficient food intake, placing special demands on nutrition management. This article presents the basics of perioperative metabolism and nutrition management of head and neck cancer patients and makes recommendations for clinical practice. Implementing a nutrition management system in head and neck cancer clinics will improve the clinical outcome and the survival of the patients.

Abstract
PURPOSE Premature unilateral coronal craniosynostosis results in distinctive cranial and facial abnormalities of varying severity, including orbital dystopia and an abnormal head shape. As the face is affected, these children may encounter stigmatization. To avoid this scenario, many parents elect for their child to undergo surgical correction. Laypeople's perception of children with either untreated or treated unilateral coronal craniosynostosis (UCS) has not yet been objectively evaluated. METHODS This study introduces eye tracking as an objective instrument in order to evaluate the perception of 14 children with coronal synostosis, both pre- and postoperatively. Age-matched healthy children served as a control group. Using standardized photos, the involuntary eye movements and the fixations of 30 unaffected laypeople were evaluated. RESULTS In the untreated children, whose faces were characterized by striking orbital dystopia, the eyes drew more attention than those of the healthy children. The results of our study demonstrate that the operative correction of unilateral coronal synostosis results in the normalization of the asymmetry of the fronto-orbital region, whereas the C-shaped deformity of the midface, which is not addressed via surgery, subsequently attracts more attention. CONCLUSION Eye tracking objectively evaluates both the perception of craniofacial abnormalities and the extent of the approximation of normality after surgical correction. We introduce eye tracking as an objective measurement tool for craniofacial abnormalities for the first time.

Abstract
INTRODUCTION There is ongoing discussion on the diagnostic methods, the need of surgical treatment, and the surgical strategies for premature craniosynostosis. MATERIALS AND METHODS This study examined the operative procedure of a standardized broad median craniectomy, active tilting of the forehead, and bitemporal greenstick fracturing in children with premature sagittal craniosynostosis. To objectively analyze the direct surgical results, we used a 3D stereophotogrammetry scanner, as previously described. RESULTS A 3D analysis showed a significant increase in the width, cranial index (CI), head and coronal circumferences, intracranial volume, and cranial base width after surgery. Head length was the only parameter that demonstrated a significant decrease postoperatively. Asymmetry and the 30° diagonal difference showed no significant changes. CONCLUSION 3D stereophotogrammetry is a reliable and valuable tool with no side effects. It demonstrated that the extended surgical procedure achieves good postoperative results with a reduced length and increased width and, therefore, an improved CI. Additionally, the total intracranial volume was significantly increased after surgery.

Abstract
BACKGROUND In oral squamous cell carcinoma (OSCC), cervical lymph node status is the most important prognostic factor. Compared to elective neck dissection, reduced morbidity and better quality of life was demonstrated for sentinel lymph node biopsy, which is controversial because of the reduced detection rate of sentinel lymph nodes in close proximity to the injection site (also known as the shine-through phenomenon). METHODS We report the case of a 44-year-old woman with a biopsy-proven early OSCC of the anterior floor of the mouth, who received SLNB guided with freehand single-photon emission CT (fhSPECT), a system for the 3D visualization of radioactivity in the body. RESULTS One level III sentinel lymph node and 1 level I sentinel lymph node, in close proximity to the injection site, were detected and dissected. The level I sentinel lymph node contained a metastasis. CONCLUSION Using fhSPECT, the issue outlined was overcome, and the precise histopathological lymph node status (pN1; 1 of 49) was determined.

Abstract
BACKGROUND Langerhans cell histiocytosis (LCH, histiocytosis X, ICD-O 9751/1) refers to a neoplastic proliferation of Langerhans cells. The course of the disease determines the treatment and prognosis. Solitary forms (eosinophilic granuloma) and limited multilocational lesions may be treated successfully with local surgical intervention and intralesional corticosteroid injection. PURPOSE Presentation of our own case will review LCH, a very rare disease entity in oral-facial surgery and will document that intralesional corticosteroid injection is a less invasive alternative to the classical surgical curettage and local radiation therapy. CASE REPORT In a 10-year-old boy, a progressive, pressure-sensitive swelling had developed within 1 week in the left paramandibular and submandibular area. Dental status was good. Diagnostic imaging demonstrated a diffusely contoured osteolysis caudal to tooth germ 37 with infiltration of the adjacent chewing muscles. Histological evaluation of the intraoral biopsy sample established an LCH. Having excluded a multifocal form of LCH, treatment with intralesional injection of methylprednisolone 200 mg was chosen. Symptoms of pain were quickly relieved and the swelling receded. Follow-up visits 6 weeks, 3 months, and 6 months after corticosteroid injection revealed continuous regression of mandibular osteolysis. OPG and MRI after 17 months demonstrated a good osseous consolidation in the left mandibular angle area, but a still discernible bone marrow edema. Development of the intralesional tooth germ 37 appeared normal. CONCLUSION Local surgical interventions continue to be central to the range of accepted therapeutic measures. However, the increasing numbers of reports on the successful treatment of solitary LCH by intralesional corticosteroid injection suggest that this treatment option should be considered especially in children to preserve tooth germs.

Abstract
BACKGROUND Undifferentiated human dental cells and especially human dental follicle cells are interesting for potential dental treatments. These somatic stem cells are cultured usually in cell culture medium containing bovine serum. In the age of bovine spongiform encephalopathy (BSE), a serum-free cell culture system for dental follicle cells are recommended, if these cells will be applied in dentistry. PURPOSE However, less is known about the cultivation of dental follicle cells in serum-replacement medium. In this study, we cultivated dental follicle cells in serum-free cell culture medium, which is normally applied for neuronal stem/progenitor cells. MATERIALS AND METHODS Dental follicle cells were cultivated in both serum-free and serum-containing cell culture media, and gene expression profiles were recorded for connective tissue markers collagen type I and type III and for the human dental follicle cell marker nestin. RESULTS It is interesting to note that the gene expressions of collagens and nestin were similar after applying both cell culture conditions. CONCLUSION Although the gene expression of dental follicle cell markers was unchanged, a more appropriate serum-free cell culture medium is recommended for cell proliferation of dental follicle cells.

Abstract
BACKGROUND Three different fungal-related clinical pictures have to be differentiated in the paranasal sinuses: allergic fungal sinusitis, fungus ball and invasive sinonasal mycosis. PURPOSE A morphological reevaluation of fungal-related diseases of the paranasal sinuses as well as a retrospective analysis of their clinical parameters was performed. PATIENTS AND METHODS 86 patients with patho-histological proven fungal-related disease of the nasal sinuses were enclosed in this study. Reevaluation and correlation of clinical and histological parameters were conducted on routine material (HE, PAS and Grocott) according to the modern morphological definitions. RESULTS Invasive sinonasal mycosis was seen in 22 cases, eleven male and eleven female, mean age 57 years (22 to 84 years). It was significantly related (nine out of 22 patients, 41%) to immunocompromising conditions: three patients had diabetes mellitus type II, five had have a radiation therapy due to carcinoma and one patient suffered from bacterial endocarditis. A fungus ball was diagnosed in 60 patients, 26 male, 34 female, mean age 54 years (22-88 years). An immunocompromising condition was seen in nine out of 60 patients (15%). Causes for immune impairment were diabetes mellitus (two patients), radiation therapy due to carcinoma (four patients), myocarditis (one patient) and chronic hepatitis (two patients). Allergic fungal sinusitis was recorded in four patients, three male, one female, mean age 43 years (17-63 years). No immunosuppression was diagnosed. CONCLUSIONS Despite the fact that allergic fungal sinusitis is the most common fungal disease of the paranasal sinuses, it is not well known among physicians and pathologists and therefore underrepresented within the diagnoses of paranasal infections. The term "aspergilloma" is imprecise and does not represent a clear diagnosis. A further differentiation in "fungus ball" (without invasion) and "invasive sinonasal mycosis" is required. The three groups of fungal-related sinusitis occur at different ages. Allergic fungal sinusitis is common among young adults. An immunocompromising condition is a prerequisite for an invasive sinonasal mycosis.

Abstract
BACKGROUND Teratomas are congenital embryonic tumours composed of a wide diversity of tissues derived from the three germinal layers (ectoderm, mesoderm, endoderm). Located in the orbit they endanger the eye and the bony structures. The main goal of treatment is preservation of the eye. In most cases this will not be feasible. CASE REPORT A newborn boy was admitted to our hospital because of a prenatally known protrusion of the right globe. On examination the baby had a large retrobulbar orbital tumour, which displaced the globe ventrally. On MRI the tumour had an extent of 5 cm. It compromised the frontal bone and reached intracranially. No other malformations were found. The tumour was transorbitally resected and the eye exenterated. A congenital mature teratoma was diagnosed. To preserve orbital volume an implant was inserted (Hema globe, 18 mm). FOLLOW-UP The healing course was uneventful. Illig implants were changed without difficulties. After 10 months an individual prosthesis was inserted. Control CT scans showed no signs of tumour. CONCLUSIONS The case presented underlines the possible extent and impact of congenital mature teratomas. Despite the extent of the tumour and the very young age of the patient a satisfactory treatment result was achieved.

Abstract
BACKGROUND With the new term "keratocystic odontogenic tumour" (KCOT) keratocyts are even in the nomenclature a close differential diagnosis to ameloblastomas (A). PURPOSE Recurrence of KCOT and A were retrospectively compared with regard to treatment and immunohistochemical markers of cell cycle and migration and cell architecture. PATIENTS AND METHODS Biopsies harvested over a period of 22 years of 101 patients (86 KCOT, 15 A) were examined. The histopathological slides were stained with H&E and with the immunohistochemical markers: Cyclin D1, Collagen IV, p16, Cox-2-Laminin-5 and Tenascin-C. RESULTS Mean age KCOT 47 years (range 14-80 years), A 41 years (range 16-79 years). Gender KCOT: m:f =2:1; A: m:f = 3:2. Region of origin mandible with predilection of the angle and the ramus: KCOT: 76; A: 12. Maxilla: KCOT: 18; A: 3. Multiple lesions were found in 5 KCOT patients. Treatment primary KCOT: cystectomy (46), cystostomy (6), cystectomy and curettage (17), cystectomy and marginal ostectomy (14), resection (11). A: resection (10), enucleation (5). Recurrence rate KCOT: 11,7% after 5,5 years. Recurrence after: cystostomy (4), cystectomy (6), cystectomy and curettage (3), cystectomy and marginal ostectomy (2). A: no recurrences. Immunohistochemistry Cell cycle associated and extracellular matrix proteins did not differ in quantity in KCOT and A, and did also not differ in recurrent and non-recurrent KCOT. CONCLUSIONS 1. KCOT are in the own cohort more likely recurrent than A. 2. Recurrence rate of KCOT can not be predicted by the used (most common) markers of cell cycle, migration and modulation of architecture. 3. Higher recurrence rate of KCOT in the patients examined is proposed due to less extensive resection.

Abstract
BACKGROUND Based on own retrospective studies a condylar head add-on system for immediate, temporary reconstruction in patients undergoing ablative surgery requiring the removal of the manibular condyle has been developed in cooperation with the Department of Oral and Maxillofacial Surgery of the University of Tennessee, USA, and the Association for the Study of Internal Fixation (AO/ASIF). PURPOSE The design of the new condylar head add-on system and its use in an anatomical dissection study on a human cadaver are introduced and discussed. DESIGN AND FIRST EXPERIENCES: The condylar replacement is made of commercial pure titanium and is conceived as an add-on system. It consists of a reconstruction plate (2.4 Uni-LOCK-System) und an adaptable condylar head that can be fitted on either side. The offset of the condylar head in a medial direction allows anatomically correct positioning of the implant. The slanted oval head shall provide a large contact area while maintaining function of the mandibular joint. The height-adjustable positioning of the condylar head add-on with four different fixations plates facilitates an intraoperative vertical correction of the condylar head without necessary bending of a new reconstruction plate. A condylar head add-on used on both sides and combined with the frequently used 2.4 Uni-LOCK-plate benefits from reduced storekeeping and turns out to be advantageous from an economic point of view. PERSPECTIVE An international, prospective multi-center study evaluating the intraoperative applicability of the new condylar head add-on system and its functional as well as aesthetic results during the first two postoperative years has started in September 2006.

Abstract
BACKGROUND Pleomorphic malignant fibrous histiocytomas (undifferentiated pleomorphic sarcomas) belong to the soft tissue tumours and are more likely in elder patients. About 3 % percent of all pleomorphic malignant fibrous histiocytomas arise in the head and neck region. 30 % of these histiocytomas develop in the paranasal sinuses. Occurrence in the periorbital region is a very rare event. In spite of their pleomorphic pattern the treatment is solely surgical excision. Haematogenic or loco-regional lymphogenic metastases are very rare. PATIENT A 91 year old female patient presented because of a prominent tumour in the upper right periorbital region. As stated in the case history, the tumour had developed within the previous 6 months. The tumour measured about 3 x 4 cm. It was tight to resiliant and seemed to not be adherent to the underlying structures. Pain or hypesthaesia were not existent. Due to the mass of the tumour a ptosis was present. Additionally, there was a mechanical lack in the movement of the eyeball in the upper direction. The papilla was vital and differentiated. Visual acuity was decreased due to a mature cataract. CLINIC Neither CT nor MRI could give a clue to the tumour entity. Infiltration of the periorbital structures or the eyeball could not be ruled out. A biopsy was classified as a malignant fibrous tumour with the subclassification of an atypical fibroxanthoma. The final histopathological classification after total excision of the tumour showed perineural growth and angioinvasion. Therefore the tumour classification was changed to pleomorphic malignant fibrous histiocytoma (undifferentiated pleomorphic sarcoma). The defect was closed with a full skin graft on the basis of a galea periosteal flap. CONCLUSION The histopathological examination could not provide the correct diagnosis initially. Immunohistochemical stainings (Vimentin) were carried out to characterise the tumour. This underlines that even with state of the art procedures the classification of neoplasias can be very difficult. In the process of finding the right diagnosis sometimes a change from benign to malignant occurs and alters the treatment regime.
