The buccal fat pad (BFP) as pedicled graft was originally used in reconstructing medium sized intraoral defects. Promising results concerning the use of BFP in cleft palate surgery have been published recently. The aim of this article is to report on the use of BFP as a pedicled graft in cleft palate surgery and to discuss promising results for this(More)
The aim of this retrospective study was to assess the incidence of postoperative hemorrhage in patients treated with coumarins without interruption of the anticoagulant treatment undergoing oral surgical procedures, mostly osteotomies for tooth removal, when compared with patients who had never been anticoagulated. Six hundred thirty-seven patients(More)
PURPOSE The surgical approaches for the open treatment of condylar process fractures have been controversial. In our study, we evaluated the morbidity of the transparotid approach during 2 years of follow-up. PATIENTS AND METHODS A total of 48 patients with condylar process Class II and IV fractures according to classification of Spiessl and Schroll, were(More)
BACKGROUND Hybrid tumours of the salivary glands are rare neoplasms. They are composed of at least two different tumour entities located in the same topographic area and account for only 0.1% of all salivary gland tumours. The most common component is an adenoid cystic carcinoma. There are several possible forms of hybrid tumours, which are most commonly(More)
OBJECTIVE Dental osteotomy, the removal of an impacted, ankylosed, or severely destroyed tooth requiring an osteotomy, is more invasive than other minor dental procedures and therefore also has a higher bleeding risk. A considerable number of patients under antiplatelet therapy interrupt their therapy perioperatively, which, however, increases the risk of(More)
BACKGROUND/AIM As already described in previous studies, neural crest stem cells (NCSCs) can be found in adult human dental pulp. The present study investigated the methodology for enrichment and differentiation-induction of the above mentioned cells. MATERIALS AND METHODS Dental pulp was extracted from human wisdom teeth of four patients and subsequently(More)
OBJECTIVES To study immunohistochemical expression of the epithelial growth factor receptor (EGFR) in oral carcinomas and the head and neck region to examine possible associations with various features of the tumors and survival of the patients. MATERIALS AND METHODS Sections were made from two tissue arrays composed of 206 oral squamous cell carcinomas(More)
The purpose of this study was to assess the risk of postoperative bleeding complications after oral procedures performed under continued mono or dual anticoagulation therapy with rivaroxaban (and aspirin). This retrospective single-center observational study included 52 oral procedures performed under continued oral anticoagulant therapy with rivaroxaban(More)
Objective, non-invasive examination, techniques in addition to clinical parameters, are required to follow-up the wound healing of flaps. With the new laser Doppler Scanner (LDI DIM 1.0 Lisca Development AB, Sweden) it is possible, for the first time, to measure and image the microcirculation continuously, non-invasively and without contact with the wound,(More)
PURPOSE Her2 (ErbB2) transforms cells when overexpressed and is an important therapeutic target in breast cancer. Contrary to breast cancer, studies on Her2 overexpression and gene amplification in squamous cell carcinomas of the head and neck region described largely different results. This study was undertaken to learn more on the prevalence and clinical(More)
