1/44. A surgical method for treating anterior skull base injuries.skull base surgery was performed on 18 patients with anterior skull base injuries. The operative technique consisted of opening the operative field in the anterior skull base via a coronal incision and a frontal craniotomy, debridement of the anterior skull base including the injured dura mater, performing drainage from the anterior skull base to the nasal cavity by ethmoidectomy, and reconstructing the resulting dural and anterior skull base defect using bilateral temporal musculo-pericranial flaps and a bone graft. Seventeen of the 18 patients recovered without any complications, although epidural abscesses in the anterior skull base had been present in four patients at the time of the operation. Only one patient developed an epidural abscess in the anterior skull base after the operation. None of the patients developed any other complications including meningitis, recurrent liquorrhoea or cerebral herniation. Satisfactory aesthetic results were achieved in 16 of the 18 patients. In one patient, uneven deformity of the forehead, which was caused by the partial sequestration of the frontal bone due to postoperative infection, was observed. In another patient, a depressed deformity of the forehead, which was caused by the partial loss of the frontalis muscle following the use of the frontal musculo-pericranial flap instead of a temporal musculo-pericranial flap, was observed. Anterior skull base reconstruction using bilateral temporal musculo-pericranial flaps provides excellent results in terms of patient recovery and aesthetics.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
2/44. acinetobacter meningitis: four nosocomial cases.We report the clinical features and therapeutic outcomes of four patients with multiantibiotic-resistant acinetobacter meningitis. There were three males and one female, aged from 17 to 49 years. Three of them had suffered from head injuries with skull fractures, and the other suffered from an intracerebral hemorrhage and underwent a craniotomy. All four patients acquired nosocomial acinetobacter meningitis, and multiantibiotic resistance developed. After treatment with imipenem/cilastatin, three of the four patients survived; one died of multiorgan failure. Because the clinical manifestations of acinetobacter meningitis are similar to those of other gram-negative bacillary meningitis, the diagnosis can only be confirmed by bacterial culture. Resistance to multiple antibiotics, including third-generation cephalosporins, is frequently seen in patients with nosocomial acinetobacter meningitis, and imipenem/cilastatin seems to be the antibiotic of choice for this potentially fatal central nervous system infection.- - - - - - - - - - ranking = 9keywords = meningitis (Clic here for more details about this article) |
3/44. Recurrent bacterial meningitis: report of two cases from Riyadh, saudi arabia.We report two cases of recurrent bacterial meningitis after head injury in two Saudi boys. The brain CT scan showed bony defects in both despite normal otolaryngeal clinical findings. One child remained well after surgical repair but the other was lost to follow-up.- - - - - - - - - - ranking = 5keywords = meningitis (Clic here for more details about this article) |
4/44. Subdural and intraventricular traumatic tension pneumocephalus: case report.Simple pneumocephalus most frequently arises as a complication of a head injury in which a compound basal skull fracture with tearing of the meninges allows entry of air into the cranial cavity. It can also follow a neurosurgical operation. Tension traumatic pneumocephalus with intraventricular extension is an extremely rare, potentially lethal condition that requires prompt diagnosis and treatment. We report the case of subdural and intraventricular accidental tension pneumocephalus occurring in a 26-year-old man as a result of skull fracture. This case is combined with rhinorrhea and meningitis that suggest some difficulties to treat. The operative procedure associated with medical treatment was performed and a good result was obtained.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
5/44. Occult craniocerebral injuries from dog bites in young children.Although dog bite injuries to the head and scalp of children occur frequently, penetrating dog bite wounds to the cranial vault occur only occasionally and may go unnoticed on initial examination. Substantial morbidity and mortality can ensue if these penetrating injuries are not detected and treated. The authors detail the evaluation of dog bites of the scalp in young children. They highlight the ease with which puncture wounds of the calvarium may be missed during physical examination as a result of scalp displacement at the time of puncture. The cranial puncture may not be large and may later be covered by scalp that returns to its native position. Well-scrutinized skull films and a careful, methodical physical examination are advocated. Recognized craniocerebral injuries should be explored. Depressed cranial fractures should be irrigated, debrided, and elevated. Dural tears should be repaired. Expedient management is necessary to prevent meningitis and its associated sequelae.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
6/44. Traumatic porencephalic cyst and cholesteatoma of the ear.Porencephalic cyst expanding into the ear is a very rare complication of temporal bone fracture. We report a case of a 20-year-old male who developed a traumatic porencephalic cyst of the temporal lobe expanding into the ear through a tegmen fracture in association with a cholesteatoma. The clinical presentation was otitic meningitis. This occurrence was not encountered in any of the cases reviewed in the literature. The diagnosis, pathogenesis, treatment and prognosis of this condition are reviewed.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
7/44. titanium mesh repair of the severely comminuted frontal sinus fracture.BACKGROUND: Severely comminuted frontal sinus fractures are difficult to contour and immobilize. Frequently, plates or wires are inadequate in fixating all fragments together, resulting in less than optimal outcomes. Advancements in the development of biomaterials have now made titanium mesh a new option for the repair of severely comminuted fractures. methods: Fourteen patients with severely comminuted frontal sinus fractures were treated with titanium mesh from 1994 to 1999. The fractures were reduced and immobilized using a simple algorithm: (1) Isolated anterior table fractures were repaired with reduced bony fragments attached to titanium mesh. (2) Anterior table fractures with nasofrontal duct involvement were repaired by sinus obliteration and anterior wall reconstruction with reduced bony fragments attached to titanium mesh. (3) Anterior and posterior table fractures with cerebrospinal fluid leak or displacement were treated with the cranialization of the sinus and anterior wall reconstruction with reduced bony fragments attached to titanium mesh. RESULTS: Of the 14 patients treated, 12 were available for postoperative evaluation. Parameters such as nasal function, cranial nerve V and VII function, cosmesis, and complications (hardware extrusions, sinusitis, meningitis, osteomyelitis, mucopyocele, brain abscess, pneumocephalus, and cerebrospinal fluid leak) were evaluated. All patients had good function of the superior division of cranial nerves V and VII. Two patients (16%) had minor wound infections, which resolved under treatment with antibiotics. All had excellent cosmetic results as measured by postreduction radiographs and personal and family perceptions of forehead contour. CONCLUSION: titanium mesh reconstruction of severely comminuted frontal sinus fractures has few complications while providing excellent forehead contour and cosmesis.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
8/44. pneumocephalus. A sign of intracranial involvement in orbital fracture.Fractures of the orbit resulting from blunt or penetrating injury that involve the paranasal sinuses may tear the dura and allow air to enter the cranial cavity (pneumocephalus). pneumocephalus is sometimes the only sign of intracranial involvement. It is characteristically delayed in onset and clinically unsuspected, so that routine follow-up roentgenograms of patients with orbitosinus fractures may be the only means of assuring early detection. Roentgenographically, the air may be seen in spidural, subdural subarachnoid, intracerebral, or intraventricular locations. Prophylactic parenterally administered antibiotics may prevent intracranial infection. However, since about 25% of patients still develop meningitis, surgical repair of the dural fistula is often necessary.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
9/44. Post-traumatic orbital cellulitis.orbital cellulitis is uncommon. It may arise as a sequel to eyelid infection, or from direct spread of infection from the paranasal sinuses; it may be of odontogenic origin and has been reported after meningitis and after nasoorbital fractures with pre-existing sinusitis. Clinically, orbital cellulitis is of great importance, as it is a severe disease with potentially disastrous consequences. It may lead to optic neuritis, optic atrophy, blindness, cavernous sinus thrombosis, superior orbital fissure syndrome, meningitis, subdural empyema, and even death. We report two cases of severe post-traumatic orbital cellulitis with subperiosteal abscesses. These were managed surgically and vision was preserved. We describe the anatomy, a classification of orbital infection, and the importance of multidisciplinary management of these cases.- - - - - - - - - - ranking = 2keywords = meningitis (Clic here for more details about this article) |
10/44. Chronic post-traumatic erosion of the skull base.Delayed post-traumatic erosion of the skull base is reported in three patients who presented as adults with cerebrospinal fluid fistulae and a history of recurrent meningitis. These skull defects were associated with herniation of the subarachnoid space into the diploe of the skull base, the paranasal sinuses and the orbit. This rare complication of head injury is assumed to have occurred as the result of a dural tear at the time of trauma. Its site probably determines whether a resulting meningocele widens the intradiploic space or broaches the cranial floor.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
