Insertion of endosseous implants in the atrophic maxilla is often complicated because of lack of supporting bone. Augmentation of the floor of the maxillary sinus with autogenous bone graft has been proven to be a reliable treatment modality, at least in the short term. The long-term clinical and radiographic outcome with regard to the grafts, the implants(More)
PURPOSE The influence of bone augmentation of the floor of the maxillary sinus for the insertion of dental implants on sinus function has not been well investigated. In this study, the influence of the sinus lift on the development of maxillary sinus pathology was evaluated using generally accepted diagnostic criteria. MATERIAL AND METHODS A group of 45(More)
In a prospective study, the effects of elevation surgery of the maxillary sinus floor on maxillary sinus physiology were assessed. Seventeen consecutive patients without preoperative anamnestic, clinical and radiological signs of maxillary sinusitis underwent sinus floor elevation surgery with iliac crest bone grafts. All patients were subjected to(More)
Although augmentation of the maxillary sinus floor with autogenous bone grafts has become a well established preimplantology procedure, its effect on the function of the maxillary sinus has not been the subject of prospective human studies. In this prospective study the effects of sinus floor augmentation on maxillary sinus performance were evaluated.(More)
A 21-year-old woman was referred by the dental practitioner to an oral surgeon concerning a hard elastic swelling of the left cheek in combination with local paresthesia. Histopathologic and radiographic examination revealed an osteosarcoma in the left segment of the maxilla. Subsequently, the patient was referred to a medical centre for head and neck(More)
Patients with hypertension can be treated by inhibition of angiotensin-converting enzyme (ACE). A major side-effect of the use of ACE-inhibitors is the development of a life threatening dyspneu by angioedema of oropharyngeal and laryngeal tissue. This severe complication is caused by interaction of ACE-inhibitors with prostaglandin and bradykinin(More)
In this paper some relevant pathological aspects on the interface of dentistry and ENT surgery are discussed. A major part of the field of ENT surgery is not available for direct inspection and/or evaluation. Therefore, ENT pathology is often overseen or not detected at an early stage. Because of frequent patient-dentist contact, also in healthy patients,(More)
Summary Placement of endosseous implants in the atrophic maxilla is often limited because of a lack of supporting bone. A technique to augment the floor of the maxillary sinus with autogenous bone graft seems to be a new reliable treatment modality. The morbidity and complication rate of augmentation of the maxillary sinus floor was studied in 75 patients.(More)
PURPOSE In maxillofacial surgery, hyperbaric oxygen treatment is used almost exclusively as adjunctive therapy for osteoradionecrosis of the mandible in irradiated patients. It also is used to prevent the occurrence of osteoradionecrosis in the irradiated patient when dental surgery is indicated. Theoretically, hyperbaric oxygen therapy should benefit the(More)
