1/31. Central cavernous hemangioma of the mandible treated by an intraoral approach.We have presented a case of surgical treatment of a central cavernous hemangioma of the mandible in which a radical deforming operation on a 12-year-old girl was avoided. A rather unique surgical approach was devised after all diagnostic criteria were available and after very careful consideration of an operative plan.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/31. Mandibular metastatic hepatocellular carcinoma: report of a case involving severe and uncontrollable hemorrhage.Hepatocellular carcinoma (HCC) is a malignant tumor with a marked tendency to spread through the portal system. Metastases from HCC usually involve lungs, surrenal glands, the skeletal and gastroenteric systems, spleen, heart and kidneys. Secondary localizations to the mandible are rare. Generally, bone metastases from HCC appear as osteolytic lesions more likely localized to the ribs, spine, femor, omer, sternum, and then to the mandible. Mandibular metastatic HCC is hemorrhagic in nature because of its hypervascularity. Any diagnostic maneuver that could end in bleeding should be avoided. Non-invasive diagnostic procedures such as computer tomography (CT) scan should be preferred. Among the invasive diagnostic procedures, only fine needle biopsy should be attempted and palliative radiotherapy could be useful for the control of local symptoms. A case report of a hemorrhagic mandibular metastatic HCC that had to be treated surgically, in order to control the severe and profuse bleeding, is presented.- - - - - - - - - - ranking = 0.4keywords = mandible (Clic here for more details about this article) |
3/31. Arteriovenous malformation of the mandible: embolization and direct injection therapy.Arteriovenous malformation (AVM) of the mandible is a rare entity but one that can be potentially fatal as a result of massive hemorrhage. Traditional treatment involved extensive surgical resection of the mandible. With the advent of improved endovascular techniques, interventional radiology is now the best method to control active hemorrhage and ultimately cure these lesions. The authors describe three cases of successfully treated mandibular AVM by percutaneous and/or endovascular techniques.- - - - - - - - - - ranking = 1.2keywords = mandible (Clic here for more details about this article) |
4/31. 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 = 0.2keywords = mandible (Clic here for more details about this article) |
5/31. Oral lesions in scurvy.scurvy is the nutritional deficiency state associated with lowered levels of ascorbic acid (vitamin C). Lack of ascorbic acid leads to suppression of collagen synthesis and the synthesis of defective collagen among other metabolic derangements. Weakening of vascular walls results in signs and symptoms mimicking other diseases such as bleeding diatheses and deep vein thrombosis. scurvy is rarely encountered in Western countries where there is a broad community understanding of the importance of nutritional requirements and where foods containing ascorbic acid are readily available. As a result of these factors early diagnosis may be hampered where it is not considered in the differential diagnosis, and consequently, prolonged suffering of the patient. scurvy is easily treated with high doses of oral ascorbic acid, although recurrences may occur. education of health care providers in recognizing the signs and symptoms of scurvy therefore cannot be over emphasized, particularly in societies in which nutritional deficiencies are considered uncommon. A case of scurvy presenting primarily with oral manifestations is reported here.- - - - - - - - - - ranking = 2.6810271440886E-5keywords = lower (Clic here for more details about this article) |
6/31. Massive bleeding from an ectopic lingual thyroid follicular adenoma during pregnancy.Ectopic thyroid is a rare developmental anomaly. It can be found anywhere between the foramen cecum and the normal position of the thyroid gland. Massive bleeding from an ectopic lingual thyroid is unusual and occasionally fatal. We present a case of a 22-year-old woman who had a large mass at the base of the tongue for over 6 years. In the sixth month of pregnancy, the patient experienced massive bleeding from the tongue base mass. A thyroid scan revealed that this mass was the only functioning thyroid tissue. Because of massive bleeding and her shock status, the patient received an emergent embolization of the bilateral lingual arteries. Then the huge lingual thyroid was subsequently excised via a mandible swing approach to prevent further episodes of bleeding. pathology analysis indicated ectopic thyroid tissue with follicular adenoma. She delivered without complications in the 36th week and had a normal baby. This case was a very rare one in our review. Although ectopic lingual thyroid usually is not managed surgically, excision of ectopic lingual thyroid can be life-saving when it is causing bleeding or airway obstruction.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
7/31. 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 = mandible (Clic here for more details about this article) |
8/31. Embolization of a life-threatening mandibular vascular malformation by direct percutaneous transmandibular puncture.vascular malformations of the mandible are uncommon, but often present with significant hemorrhage. Transarterial vessel occlusion has become a valuable primary or adjunctive treatment for such lesions, as well as for most other symptomatic congenital and acquired head and neck vascular anomalies. Permanent embolic obliteration of the malformation requires placement of occlusive material directly into the nidus (core) of the lesion. Prohibitively complex proximal vasculature may prevent successful catheter positioning and lead to failure of traditional embolotherapy. Even optimal placement of arterial embolic material may fail to fully obliterate the nidus, allowing eventual restoration of flow to the lesion due to arterial recanalization. Under such circumstances it may be possible to obliterate the malformation and control lesional hemorrhage by occlusion of the malformation or its venous drainage by direct percutaneous mandibular puncture. In our case, multiple transarterial embolizations failed to sufficiently manage a symptomatic vascular malformation. Successful embolotherapy was performed via direct puncture of the venous side of the malformation through the mandibular cortex. venous thrombosis induced concomitant occlusion of abnormal arteriovenous shunts, resulting in long-term control of life-threatening oral hemorrhage.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
9/31. Sublingual hematoma formation during immediate placement of mandibular endosseous implants.BACKGROUND: Sublingual hematoma during placement of mandibular endosseous dental implants is a rare, but potentially life-threatening, complication. The development of a sublingual hematoma during a dental procedure may result in the need for acute airway management, including intubation or even emergent tracheostomy. dental implants are becoming a well-accepted treatment, and thousands of implants are placed every year by general practitioners and specialists, with few adverse sequelae. Clinicians rarely discuss this complication with patients before surgery, and no reports of death secondary to sublingual hematoma formation have been published. The incidence of this event is difficult to ascertain, and only, a few cases have been reported. CASE DESCRIPTION: A 56-year-old man with severe caries underwent multiple mandibular tooth extractions and alveoloplasty and received endosseous implants. During the surgical procedure, the patient developed a large sublingual hematoma that required hospitalization. CLINICAL IMPLICATIONS: Practitioners who perform implant surgery in the anterior mandible should notify patients of the potential risk of sublingual hematoma formation, and be able to manage acute airway issues that may result from this complication.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
10/31. An alternative approach to maxillofacial arteriovenous malformations with transosseous direct puncture embolization.The management of arteriovenous (AVM) malformations of the jaws is complex and requires an integrated team approach. Subspecialists, such as maxillofacial surgeons, interventional radiologists, and critical care intensivists, are commonly involved in the management of these patients. The current treatment options for maxillofacial AVMs are surgical resection combined with endovascular embolization. Surgical treatment of arteriovenous malformations has been associated with significant morbidity and mortality due to potential for massive blood loss. In the pediatric population extensive resection of the craniofacial skeleton may be associated with growth disturbance, functional compromise, and cosmetic deformity. We report a novel technique using endovascular embolization via direct transosseous puncture for a high-flow vascular malformation, obviating the need for extensive surgical resection, and review the important clinical aspects of these life-threatening lesions.- - - - - - - - - - ranking = 0.0017601124373624keywords = jaw (Clic here for more details about this article) |
