Dentinogenic Ghost Cell Tumour in Childhood Involving the Temporomandibular Joint: Considerations and Therapy.

Background: Although the uncommon dentinogenic ghost cell tumour (DGCT) is a benign entity, it possesses the ability to cause widespread destruction of the jaws and to recur after bone-preserving therapy. Hence, clear margins should be achieved upon surgery, and reconstruction techniques must often be used to restore osseous defects. However, this can be challenging in cases with involvement of the temporomandibular joint (TMJ), and especially in children.

Melanotic Neuroectodermal Tumour of Infancy: Clinical Courses and Therapeutic Options-A Review of Three Cases.

Background: Melanotic neuroectodermal tumour of infancy (MNTI) is a rare benign neoplasm. MNTI appears most often during the first year of life, arises predominantly in the maxilla and tends to recur. We discuss possible therapeutic options given in the literature and within our experience in three cases.

Case report: chronic inflammatory ulcer and osteoradionecrosis of the skull following radiotherapy in early childhood.

Introduction: Chronic inflammatory diseases of the skin are the most common differential diagnosis of tumorous lesions of the craniofacial region. Detailed information about a patient's medical history is important for the clinical diagnosis of such cases. Previous radiotherapy should be taken into account, especially in cases of chronic dermatitis, since complications include osteoradionecrois of the adjacent bone strucutres with surrounding inflammation.

Total mandibular reconstruction following diffuse sclerosing osteomyelitis.

Background: Diffuse sclerosing osteomyelitis (DSO) is a non-purulent chronic recurrent inflammation and affects the mandible in many cases. Belonging to the group of autoinflammatory diseases, in children and in cases with various additional symptoms including synovitis, acne, pustulosis, hyerostosis, and osteitis (SAPHO syndrome), therapy usually consists of non-surgical treatment. Against this background, we present an unusual course of DSO in an adult female patient.

Continuity defects of the mandible: Comparison of three techniques for osseous reconstruction and their impact on implant loading.

Computer-aided design/manufacturing (CAD/CAM) is now widely used, but whether it can help to overcome complications in mandibular reconstruction and accelerate dental implantation is still a matter for debate. Therefore, we aimed to evaluate the benefits of this technique using vascularized iliac crest or fibula flaps in mandibular reconstruction, with respect to the time between reconstruction and implantation, and the ratio of planned to inserted implants. We reviewed retrospectively the records of 54 patients who underwent mandibular reconstructions between 2012 and 2016, and included in our study the last 10 cases representing each of the following groups: iliac crest flap with CAD/CAM (Group 1); fibula flap with CAD/CAM (Group 2); and fibula flap without CAD/CAM (Group 3).

Current concepts in cleft care: A multicenter analysis.

The current surgical techniques used in cleft repair are well established, but different centers use different approaches. To determine the best treatment for patients, a multi-center comparative study is required. In this study, we surveyed all craniofacial departments registered with the German Society of Maxillofacial Surgery to determine which cleft repair techniques are currently in use.

Moving the mandible in orthognathic surgery - A multicenter analysis.

Orthognathic surgery has always been a classical focus of maxillofacial surgery. Since more than 100 years, various surgical techniques for mandibular repositioning have been developed and clinically tested. Since the establishment of plate and screw osteosynthesis, orthognathic surgery became more stable and safe.

Longtime undetected microcystic adnexal carcinoma of the scalp: considerations and implications.

Background: Microcystic adnexal carcinomas (MACs) are slow-growing and often asymptomatic malignant skin tumours that usually develop on the facial skin and may reach considerable size. We present an uncommon case of MAC arising on the hair-bearing scalp and discuss our experiences and considerations.

Case Report: A 58-year-old female was admitted with a histopathologically secured diagnosis of MAC of the temporal and occipital regions that had expanded to 10 × 12 cm.

Perceptions of Pre- to Postsurgical Profile Changes in Orthognathic Surgery Patients and Their Correlation with Photogrammetric Changes: A Panel Study.

Purpose: The objective was to compare the pre- and postsurgical profile changes after surgical correction of prognathism and maxillary hypoplasia, as perceived by panels of orthodontists, maxillofacial surgeons, laypersons and patients and to identify photogrammetric changes that might be related to preferred ratings.

Materials And Methods: Each panel consisted of six males and six females who rated sets of pre- and postsurgical lateral photographs of 20 female and 20 male patients using a five-point scale. Patients rated their own set of photographs.

Orbital lobe resection provides a definite diagnosis of lacrimal gland lesions: a report of three cases.

Background: Entities of lacrimal gland lesions comprise almost inflammatory and lymphoproliferative processes as well as benign and malignant solid tumors and usually cannot be differentiated by magnetic resonance imaging (MRI) exclusively. Hence, representative tissue samples are needed to arrive at sufficient histopathological diagnosis for further treatment decisions.

Case Report: Three women aged between 18 and 67 years were admitted to our center with clinical signs of a space-occupying mass in the lacrimal fossa.

Comparison of intraoperative time measurements between osseous reconstructions with free fibula flaps applying computer-aided designed/computer-aided manufactured and conventional techniques.

Purpose: We aimed to determine whether computer-aided designed/computer-aided manufactured (CAD/CAM) techniques could save intraoperative time compared with the conventional technique, by comparing flap harvesting and ischemia times, and subsequently impact flap survival.

Methods: Twenty patients underwent concurrent osteocutaneous fibula flaps, either with (n = 10) or without (n = 10) the CAD/CAM technique. Demographic data, clinical history, complications, number of osseous segments, and times for virtual planning, flap harvesting, flap ischemia, tourniquet inflation, and total reconstruction were recorded.

Costs incurred by applying computer-aided design/computer-aided manufacturing techniques for the reconstruction of maxillofacial defects.

This study aims to evaluate the additional costs incurred by using a computer-aided design/computer-aided manufacturing (CAD/CAM) technique for reconstructing maxillofacial defects by analyzing typical cases. The medical charts of 11 consecutive patients who were subjected to the CAD/CAM technique were considered, and invoices from the companies providing the CAD/CAM devices were reviewed for every case. The number of devices used was significantly correlated with cost (r = 0.

Application of computer-aided designed/computer-aided manufactured techniques in reconstructing maxillofacial bony structures.

Background: Today, virtually planned surgery and computer-aided designed/computer-aided manufactured (CAD/CAM) tools to reconstruct bony structures are being increasingly applied to maxillofacial surgery. However, the criteria for or against the usage of the CAD/CAM technique are disputable, since no evidence-based studies are available. Theoretically, the CAD/CAM technique should be applied to complex cases.

Mucoepidermoid carcinoma of the palate in a 5-year-old girl: case report and literature review.

Background: Minor salivary gland tumors in children are uncommon. However, despite the low overall incidence, there is a high incidence of malignancy in these young patients which is reported to be above 50 %, with mucoepidermoid carcinoma (MEC) predominating. We hope that this case report will contribute to the enlightenment of the behavior and prognosis of pediatric MEC of palatal minor salivary gland tumors.

Clinical course and implications of congenital nasal pyriform stenosis and solitary median maxillary central incisor in a newborn: a case report.

Introduction: Congenital nasal pyriform aperture stenosis and solitary median maxillary central incisor are uncommon anomalies and are associated with further malformations. Solitary median maxillary central incisor itself has initially no impact on a child's health, but congenital nasal pyriform aperture stenosis is a potentially life-threatening condition.

Case Presentation: A Caucasian baby boy showed severe dyspnoea and was intubated orotracheally.

Osteonecrosis of the maxilla related to long-standing methamphetamine abuse: a possible new aspect in the etiology of osteonecrosis of the jaw.

Background: Osteonecrosis of the jaw (ONJ) related to toxic effects of illicit drugs such as cocaine is not very common and might be overshadowed today by the incidence of bisphosphonate-related osteonecrosis of the jaw. However, we present a case which suggests a close relationship between abuse of the illicit drug methamphetamine (MA) and ONJ.

Case Report: A 44-year-old male with extended osteonecrosis of the maxilla admitted chronic abuse and synthesis of MA for at least the previous two decades.

Adenoid cystic carcinoma of the skull base mimicking temporomandibular disorder.

Background: Temporomandibular disorder (TMD) involves problems of the temporomandibular joint and its adjacent muscular system. Because TMD prevalence is high among Western populations, complaints in these regions are generally attributed to TMD. However, in rare cases, TMD symptoms are mimicked by malignant tumors of the head.

Limitations of internal distraction devices in mature patients with cleft lip and palate and severe midface hypoplasia.

Purpose: We evaluated case-sensitive limitations of internal distraction devices (IDDs) to reveal further options for satisfactory outcomes.

Patients And Methods: Two male cleft patients aged 22 years (P1) and 20 years (P2) with severe maxillary hypoplasia were treated over 18 months. Cephalometric analyses and analyses of A-point movements by superimposing lateral cephalograms were done before and after activation of IDDs and after bimaxillary surgery (BIMAX).

Microcystic adnexal carcinoma of the upper lip misdiagnosed benign desmoplastic trichoepithelioma.

Background: Desmoplastic trichoepithelioma (DT) is a benign appendageal tumour predominately localized on the facial skin. The histological diagnosis can be difficult in some cases. Partial malignant transformation of a DT is a rarity and a complete transformation has never been described in literature.

Soft tissue response in orthognathic surgery patients treated by bimaxillary osteotomy: cephalometry compared with 2-D photogrammetry.

Purpose: Since improvement of facial aesthetics after orthognathic surgery moves increasingly into the focus of patients, prediction of soft tissue response to hard tissue movement becomes essential for planning. The aim of this study was to assess the facial soft tissue response in skeletal class II and III patients undergoing orthognathic surgery and to compare the potentials of cephalometry and two-dimensional (2-D) photogrammetry for predicting soft tissue changes.

Material And Methods: Twenty-eight patients with class II relationship and 33 with class III underwent bimaxillary surgery.

A rare association: basal cell carcinoma in a vitiliginous macula.

Background: Today, no proven significant association was detected between sun-exposed vitiliginous patches and non-melanotic skin cancers. In fact, the occurrence of a basal cell carcinoma (BCC) in vitiliginous patches seems to be extremely rare.

Case Report: We present a case of a 33-year-old female patient suffering from BCC in a vitiliginous patch on the cheek.

Perception of improvement after orthognathic surgery: the important variables affecting patient satisfaction.

Purpose: We evaluated which factors affect patient satisfaction and if patient expectations were fulfilled after orthognathic surgery.

Methods: Questionnaires consisting of 14 questions were given 1 year after bimaxillary osteotomy for class-III correction to subjects. Six questions were answered using an 11-point rating scale based on a visual analog scale (VAS; 0 = poor; 10 = excellent).
