1/17. Biportal endoscopic removal of a primary intraventricular hematoma: case report.Primary intraventricular hematomas account for approximately 6% of all intracerebral hematomas. If the clot blocks cerebrospinal fluid (CSF) pathways, surgical intervention, which may be of different types, can be life-saving. In the case reported here, after careful preoperative planning the use of two rigid endoscopes permitted the removal of most of the intraventricular clot and restoration of CSF circulation by creation of a 3rd ventriculostomy within the same procedure and no later treatment was necessary. Repeated CT scans proved that only a small portion of the intraventricular clot remained in the ventricular system. The ventricular size normalised, and the patency of the artificial hole in the floor of the 3rd ventricle was demonstrated both by the rapidly improving clinical picture of the patient and by flow-sensitive MRI studies. For individuals who suffer primary intraventricular hemorrhage and later develop occlusive hydrocephalus, endoscopic removal of the clot and 3rd ventriculostomy might offer a more adequate treatment option than external ventricular drainage.- - - - - - - - - - ranking = 1keywords = floor (Clic here for more details about this article) |
2/17. Emergency tracheostomy following life-threatening hemorrhage in the floor of the mouth during immediate implant placement in the mandibular canine region.BACKGROUND: The edentulous interforaminal mandibular area is frequently the preferred area for implant placement. methods: A case of emergency tracheostomy following life-threatening hemorrhage in the floor of the mouth during immediate implant placement in the mandibular canine region is described. The probable cause was bleeding from the sublingual artery or a branch of that artery following implant perforation of the lingual cortex. RESULTS: Healing was uneventful and the patient was released from the hospital after 11 days. Three years later, CT showed a well-osseointegrated implant with a severe buccolingual inclination. CONCLUSIONS: It is stressed that short implants (14 mm or less) should be used in the mandibular canine region and that effective treatment of this complication is essential.- - - - - - - - - - ranking = 6.5827872682681keywords = floor, mouth (Clic here for more details about this article) |
3/17. Endoscopic and radiological features of intramural esophageal dissection.A 41-year-old woman was admitted to our hospital complaining of chest pain, dysphagia, and odynophagia after an upper respiratory tract infection and nasogastric tube insertion. An upper endoscopy showed a large submucosal bulge along the posterior wall from the upper esophagus with mucosal tears and bridge formation, extending down to the lower esophagus. A barium esophagogram revealed a "double-barreled" esophagus, and chest computed tomography (CT) scan showed eccentric thickening of the esophageal wall. The diagnosis of intramural esophageal dissection (IED) was made and the patient was managed conservatively with nothing by mouth and intravenous hydration. The clinical course was uneventful; the patient was discharged later and up to the time of writing has been completely asymptomatic, with normal swallowing function.- - - - - - - - - - ranking = 0.31655745365361keywords = mouth (Clic here for more details about this article) |
4/17. Haematoma of the floor of the mouth following implant placement.Placement of implants in the anterior mandibular region is generally regarded as a routine, safe procedure. This case report describes an extensive haematoma in the floor of the mouth, following such a procedure, which rapidly became life-threatening, requiring an emergency tracheostomy to establish a surgical airway. The anatomic, radiographic and surgical aspects to the problem are discussed. Finally, when undertaking such procedures it is advisable to perform them reasonably close to a hospital where such a complication can be effectively and promptly handled by suitably trained persons.- - - - - - - - - - ranking = 6.5827872682681keywords = floor, mouth (Clic here for more details about this article) |
5/17. Proposed use of prophylactic decompressive craniectomy in poor-grade aneurysmal subarachnoid hemorrhage patients presenting with associated large sylvian hematomas.OBJECTIVE: As a group, patients who present in poor neurological grade after aneurysmal subarachnoid hemorrhage (SAH) often have poor outcomes. There may be subgroups of these patients, however, in which one pathological process predominates and for which the initiation of specific therapeutic interventions that target the predominant pathological process may result in improved outcome. We report the use of prophylactic decompressive craniectomy in patients presenting in poor neurological condition after SAH from middle cerebral artery aneurysms with associated large sylvian fissure hematomas. Craniectomy allowed significant parenchymal swelling in the posthemorrhagic period without increased intracranial pressure (ICP) or herniation syndrome. methods: Eight patients (mean age, 56.5 yr; age range, 42-66 yr) presented comatose with SAH (five Hunt and Hess Grade IV, three Hunt and Hess Grade V). Radiographic evaluations demonstrated middle cerebral artery aneurysm and associated large sylvian fissure hematoma (mean clot volume, 121 ml; range, 30-175 ml). patients were brought emergently to the operating room and treated with a modification of the pterional craniotomy and aneurysm clipping that included a planned craniectomy and duraplasty. A large, reverse question mark scalp flap was created, followed by bone removal with the following margins: anterior, frontal to the midpupillary line; posterior at least 2 cm behind the external auditory meatus; superior up to 2 cm lateral to the superior sagittal sinus; and inferior to the floor of the middle cranial fossa. Generous duraplasty was performed using either pericranium or suitable, commercially available dural substitutes. RESULTS: All of the eight patients tolerated the craniectomy without operative complications. Postoperatively, all patients experienced immediate decreases in ICP to levels at or below 20 mm Hg (presentation mean ICP, 31.6 mm Hg; postoperative mean ICP, 13.1 mm Hg). ICP control was sustained in seven of eight patients, with the one exception being due to a massive hemispheric infarction secondary to refractory vasospasm. Follow-up (> or = 1 yr, except for one patient who died during the hospital stay) demonstrated that the craniectomy patients had a remarkably high number of good or excellent outcomes. The outcomes in the hemicraniectomy group were five good or excellent, one fair, and two poor or dead. CONCLUSION: The data gathered in this study demonstrate that decompressive craniectomy can be performed safely as part of initial management for a subcategory of patients with SAH who present with large sylvian fissure hematomas. In addition, the performance of decompressive craniectomy in the patients described in this article seemed to be associated with rapid and sustained control of ICP. Although the number of patients in this study is small, the data lend support to the hypothesis that decompressive craniectomy may be associated with good or excellent outcome in a carefully selected subset of patients with SAH.- - - - - - - - - - ranking = 1keywords = floor (Clic here for more details about this article) |
6/17. Spontaneous sublingual hematoma as a complication of severe hypertension: first report of a case.We describe what we believe is the first reported case of a sublingual hematoma secondary to severe hypertension. The patient, a 77-year-old woman, experienced a spontaneous hematoma of the floor of the mouth, tongue, and sublingual space that eventually caused an airway obstruction. We performed an emergency tracheostomy under local anesthesia and then evacuated the hematoma through an incision along the floor of the mouth. The patient recovered uneventfully.- - - - - - - - - - ranking = 2.6331149073072keywords = floor, mouth (Clic here for more details about this article) |
7/17. Case of sublingual hematoma threatening airway obstruction.BACKGROUND: The complications of warfarin therapy have classically been described as bleeding in the genitourinary and gastrointestinal tracts, skin, central nervous system, nose, penis, or retroperitoneum. However, rarely warfarin may cause bleeding that compromises a patient's airway. A sublingual haematoma is an example of such a complication. Only 10 previous cases of sublingual haematomas have been reported. CASE REPORT: We describe the case of a 56 year-old woman receiving oral anticoagulation who presented with a sore throat and hoarseness. Examination of her oral cavity revealed a soft, red, submucosal swelling involving the floor of mouth and ventral lingual surface bilaterally. No signs of airway compromise were observed. The patient's PT-INR was 10. Given the potential for rapid airway obstruction, the patient was admitted to a unit with closely monitored beds. Her coagulation disturbance was corrected medically and her haematoma resolved. The patient was discharged to the care of her family physician. CONCLUSIONS: This case makes several important points. First, the case describes a rare, but life-threatening complication of warfarin therapy. Second, the initial signs of a sublingual haematoma are reviewed. Given the vagueness of these signs, diagnosis requires a high index of suspicion on the part of the physician. Finally, the case describes successfully management of this disorder without the use of a surgical airway. For this patient, reversal of her anticoagulation and vigilant monitoring saved her from having a surgical airway placed.- - - - - - - - - - ranking = 1.3165574536536keywords = floor, mouth (Clic here for more details about this article) |
8/17. Critical hemorrhage in the floor of the mouth during implant placement in the first mandibular premolar position: a case report.Although dental implantation is considered to be a safe surgical procedure, this report focuses on a critical hemorrhaging episode associated with implant placement in the first mandibular premolar position. Excessive bleeding and formation of massive lingual, sublingual, and submandibular hematomas were the result of arterial trauma that occurred during the osteotomy preparation. The vascular injury was induced through a perforation of the lingual mandibular cortex. Critical bleeding was conservatively controlled and the case was further handled efficiently with an expectant airway management in a hospital environment. Similar case reports are reviewed in an attempt to draw attention to this rare but potentially life-endangering risk of implant dentistry. Common causes of severe hemorrhage in the floor of the mouth, anatomical considerations, bleeding control measures, and related airway issues are also discussed.- - - - - - - - - - ranking = 6.5827872682681keywords = floor, mouth (Clic here for more details about this article) |
9/17. Compressive optic neuropathy after use of oxidized regenerated cellulose in orbital surgery: review of complications, prophylaxis, and treatment.PURPOSE: We report 2 cases of compressive optic neuropathy after use of oxidized regenerated cellulose (ORC) in orbital surgery. To our knowledge, no complications have been reported previously after use of this material in orbital surgery. We also review the complications related to its retention at operative sites outside the orbit and recommend precautions to avoid them. DESIGN: Retrospective interventional case reports. PARTICIPANTS: Two patients with compressive optic neuropathy after use of ORC in orbital surgery. methods: case reports from 2 different clinics and review of the English scientific literature. MAIN OUTCOME MEASURES: Best-corrected visual acuity, extraocular motility, proptosis, and chemosis. RESULTS: One patient underwent orbital exploration and biopsy of an orbital tumor, and the second had repair of an orbital floor fracture. Postoperatively, both presented with chemosis, ophthalmoplegia, and progressive loss of vision. Orbital imaging revealed a retrobulbar soft-tissue density compatible with hematoma. Repeat orbital exploration revealed the soft-tissue mass to be swollen ORC. CONCLUSIONS: Retained intraorbital ORC may cause a compartment syndrome and should be suspected in postoperative patients with orbital symptoms. When ORC is used around the optic nerve, it should be removed after hemostasis is achieved.- - - - - - - - - - ranking = 1keywords = floor (Clic here for more details about this article) |
10/17. Floor of mouth haemorrhage and life-threatening airway obstruction during immediate implant placement in the anterior mandible.A majority of the procedures performed in the dental office setting are considered safe and minimally invasive. Despite this fact, as healthcare providers it is our responsibility to be able to anticipate, recognize and manage life-threatening emergencies that may occur. In the following report, the authors will describe a life-threatening complication that resulted from the placement of mandibular implants.- - - - - - - - - - ranking = 1.2662298146144keywords = mouth (Clic here for more details about this article) |
