1/7. quinine induced coagulopathy--a near fatal experience.A 67 year old man presented to his local dentist for restorative treatment. He stated he was fit and well and denied taking any medications. When he was given an inferior alveolar nerve block, excessive bleeding was noted at the injection site and the dentist advised the patient see an oral and maxillofacial surgeon. An appointment was made for the patient but he did not attend. Three days later, he presented with evidence of massive deep haemorrhage to the point of airway compromise. He underwent hospital admission, early intubation, intensive care for nine days and hospitalization for six weeks. The cause of his bleeding was a severe thrombocytopoaenia, induced by chronic ingestion of quinine. He was self-medicating with this to relieve muscular cramps. Despite this experience, the patient continued to deny that quinine was the cause of his problem and that he had failed in his obligations to advise the dentist of his drug history. dentists need to be alert to the risk that patients may not reveal their true medical history. There are, however, obligations on the dentist to ensure the accuracy of information the patient gives and to ensure that patients whom they believe are at risk follow their advice. Teamwork and skillful airway management prevented this patient's demise.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/7. Near-fatal airway obstruction after routine implant placement.Implants have gained tremendous popularity over the past two decades, and their placement in the interior edentulous mandible has become routine. A case of near-fatal airway obstruction secondary to sublingual bleeding and hematoma is presented. The complication, anatomy of the area, and previous literature are reviewed, as are precautions to implant placement and other surgical procedures near the floor of the mouth. Although placing dental implants is generally a benign procedure, practitioners must be prepared for potential complications and have a rehearsed plan of action for the treatment of emergent situations. The floor of the mouth contains branches of the submental and sublingual and mylohyoid arteries that may lead to life-threatening complications. This caution obviously extends to any dentoalveolar surgical procedures that concerns the floor of the mouth such as tori removal, extractions, and iatrogenic dental injuries.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
3/7. Alveolar soft-part sarcoma of the tongue.Alveolar soft-part sarcoma is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. This neoplasm may mimic benign vascular neoplasms or malformations but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. We present a case of alveolar soft-part sarcoma of the tongue and emphasize its radiologic and clinical features.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
4/7. Important arterial supply of the mandible, control of an arterial hemorrhage, and report of a hemorrhagic incident.Penetration of the mandibular cortex during dental implant surgery may damage 3 important arteries and could lead to life-threatening circumstances. To lessen the likelihood of lateral angulations and cortical perforations, dental implants of less than 14 mm may be considered for the mandible. The courses of the inferior alveolar, facial, and lingual arteries and their branches are reviewed. Management of hemorrhage from a branch of the lingual or facial arteries may require an extraoral approach for ligation, because the mylohyoid, sublingual, and submental arteries can anastomose and be anatomically variable as well. A violation of 1 of these may be difficult to manage and lead to a compromise of the airway. A cortical perforation may be avoided by studying the anatomy of the ridge being treated. This article discusses what procedures to perform to obtund bleeding from 1 of these arteries and the technique of performing an emergency tracheotomy.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
5/7. Dentoalveolar trauma in a patient with chronic idiopathic thrombocytopenic purpura: a case report.A case is presented of a 13-year-old boy with chronic idiopathic thrombocytopenic purpura (ITP) who sustained traumatic labial luxation of both lower central incisors, with partial alveolar fracture resulting in displacement of the labial alveolar plate. Intravenous immunoglobulin (Fleibogamma, 1 g/kg body weight x 2 days) was administered, resulting in the patient's platelet count rising from 15,000/mm3 to 70,000/mm3. Under general anesthesia, the displaced lower labial alveolus and luxated teeth were repositioned and splinted 2 days following trauma. Healing was uneventful. Subsequently, both lower central incisors became nonvital and were endodontically treated. The dental treatment of this patient with ITP is discussed in terms of emergency management, and subsequent care.- - - - - - - - - - ranking = 6keywords = alveolar (Clic here for more details about this article) |
6/7. polycythemia vera in an oral surgical patient. A case report.polycythemia vera is a stem cell disorder that results in an increase in the production of red blood cells. Although numerous mechanisms have been suggested, the cause of the disease is unknown. diagnosis is based on clinical and laboratory presentation. This article reviews the history of polycythemia vera and illustrates a representative case report of the disease process. Postoperative morbidity in the surgical patient is discussed with respect to preoperative therapeutic control. Recommendations are made for preoperative therapy in patients undergoing oral and maxillofacial surgery.- - - - - - - - - - ranking = 0.00093305218554513keywords = process (Clic here for more details about this article) |
7/7. mucus escape reaction that involves the mandible: a case report and diagnostic imaging considerations.We present a case of mucus escape reaction in which we encountered difficulty in interpreting the images acquired by plain radiography, computed tomography, and magnetic resonance imaging. The 48-year-old male Japanese patient was referred for evaluation of a gradual swelling subjacent to the inferior border of the left mandible. At the early imaging examinations, magnetic resonance imaging provided information crucial to resolving the issue of whether the lesion consisted of a central malignant disease process or a malignant disease in the submandibular space or both of these two separate disease entities. magnetic resonance imaging demonstrated no evidence of tumorous lesion, but rather showed a fluid-containing cavity that was also confirmed by the subsequent intrasurgical inspection. On further consideration of these imaging findings, we concluded that the entity was mucus escape reaction with simultaneous occurrence of an intraconnective tissue hemorrhage adjacent to the left submandibular gland, concomitant extensive bony defect of the left mandible and lingual cortical defect, and chronic sialoadenitis of the left submandibular gland.- - - - - - - - - - ranking = 0.00093305218554513keywords = process (Clic here for more details about this article) |
