1/239. 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 = bone (Clic here for more details about this article) |
2/239. temporal bone fracture following blunt trauma caused by a flying fish.Blunt trauma to the temporal region can cause fracture of the skull base, loss of hearing, vestibular symptoms and otorrhoea. The most common causes of blunt trauma to the ear and surrounding area are motor vehicle accidents, violent encounters, and sports-related accidents. We present an obscure case of a man who was struck in the ear by a flying fish while wading in the sea with resulting temporal bone fracture, sudden deafness, vertigo, cerebrospinal fluid otorrhoea, and pneumocephalus.- - - - - - - - - - ranking = 2.5keywords = bone (Clic here for more details about this article) |
3/239. cochlear implantation following temporal bone fracture.Seven cases of profound hearing impairment following either unilateral or bilateral temporal bone fracture are presented who were implanted with the Nucleus 22 channel or Ineraid devices. Six patients suffered bilateral temporal bone fractures. One patient had prior congenital unilateral profound hearing impairment. This patient suffered a unilateral temporal bone fracture. Six patients became regular users of their implants. One gained little benefit and became a non-user. Two of the regular users experienced facial nerve stimulation, which could not be programmed out. In these two cases the implant was removed and the contralateral ear successfully implanted. Implant-aided audiometry demonstrated a hearing threshold of 40-50 dB at nine months after switch-on. The reliability of computed tomography (CT) scanning in predicting cochlear patency in cases of temporal bone fracture will be discussed. The benefit of complimentary imaging with magnetic resonance (MR) is highlighted.- - - - - - - - - - ranking = 4keywords = bone (Clic here for more details about this article) |
4/239. Cranioplasty: don't forget the patient's own bone is cheaper than titanium.Many calvarial bone defects are still being repaired using non-biological materials such as titanium when a patient's own bone can provide an alternative with all the immediate and long-term biological advantages (and resource benefits) that come with using autologous tissues.- - - - - - - - - - ranking = 3keywords = bone (Clic here for more details about this article) |
5/239. Bilateral facial nerve paralysis with craniofacial trauma.Bilateral facial paralysis (BFP) is a very rare condition, unlike its unilateral counterpart. Causes of BNP include a wide variety of diseases and its differential diagnosis can be challenging. We report a case of BFP secondary to craniofacial trauma, with unilateral orbitozygomatic and bilateral temporal bone fractures.- - - - - - - - - - ranking = 0.5keywords = bone (Clic here for more details about this article) |
6/239. Intradiploic hematoma after skull fracture: case report and literature review.BACKGROUND: Intradiploic hematoma of the skull was first reported in 1934. The pathogenesis of this lesion is unclear. It is a very rare benign reactive process occurring after minor head trauma, with only seven cases reported in the literature to date. CASE DESCRIPTION: A 3-year-old right hand dominant male presented with a non-tender parietal scalp swelling of a 1-year duration. history included a skull fracture located in the same region 24 months before presentation. Neurological examination was unremarkable. Pathological examination after curettage of the lesion revealed features consistent with organizing hematoma. CONCLUSIONS: The pathology of chronic diploic hematoma mimics aneurysmal bone cyst, giant cell tumor, giant cell reparative granuloma, fibrous dysplasia, eosinophilic granuloma, intradiploic epidermoid and dermoid cyst, cavernous hemangioma, circumscribed osteomyelitis, and tuberculous granuloma. Chronic diploic hematoma is a lesion that must be differentiated from various skull lesions both radiologically and histologically as it is amenable to treatment with a complete cure once excised.- - - - - - - - - - ranking = 0.5keywords = bone (Clic here for more details about this article) |
7/239. Transverse clivus fracture: case presentation and significance of clinico-anatomic correlations.BACKGROUND: Bilateral transverse basal skull fractures resulting from lateral crushing injuries involve fractures of the clivus that present clinically with multiple cranial nerve injuries and possible delayed vascular injuries due to the tight neural and vascular entry and exit routes present in this region. A case of a young patient with an extensive basal skull fracture is presented with description of the clinical signs and symptoms in relation to the neuroradiological findings. Clinico-anatomic correlations have been reiterated. CASE DESCRIPTION: A case of a young patient suffering a bilateral crush injury resulting in a basal transverse clivus and petrous bone fracture is presented. Multiple cranial nerve injuries, unilateral and bilateral, were present (CN III, VI, VII). This clinical presentation correlated well with the anatomical location and extension of the respective cranial nerves at the level of the skull base and along the fracture line extending bilaterally through the clivus and petrous bone. CONCLUSIONS: Initial neurological and neuroradiological investigations should be aimed at promptly detecting cranial nerve injuries and their correlating fracture injuries at the skull base. The possible development and progression of delayed neurological deficits should also be kept in mind and investigated.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
8/239. 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 = 0.5keywords = bone (Clic here for more details about this article) |
9/239. Parietal pseudofracture and spontaneous intracranial hemorrhage suggesting nonaccidental trauma: report of 2 cases.Massive intracranial hemorrhage, no history of trauma and radiographic findings that were initially interpreted as linear parietal fractures raised the possibility of nonaccidental trauma in 2 infants. Both had severe coagulopathy, 1 due to hemorrhagic disease of the newborn (vitamin k deficiency) and the other due to disseminated herpes simplex virus infection. Both infants died. At autopsy, the parietal bone abnormalities were not fractures, but proved to be an anomalous suture in 1 and a connective tissue fissure in the other.- - - - - - - - - - ranking = 0.5keywords = bone (Clic here for more details about this article) |
10/239. Dislocation of the incus into the external auditory canal after mountain-biking accident.We report a rare case of incus dislocation to the external auditory canal after a mountain-biking accident. otoscopy showed ossicular protrusion in the upper part of the left external auditory canal. CT indicated the disappearance of the incus, and an incus-like bone was found in the left external auditory canal. There was another bony and board-like structure in the attic. During the surgery, a square-shaped bony plate (1 x 1 cm) was found in the attic. It was determined that the bony plate had fallen from the tegmen of the attic. The fracture line in the posterosuperior auditory canal extending to the fossa incudis was identified. According to these findings, it was considered that the incus was pushed into the external auditory canal by the impact of skull injury through the fractured posterosuperior auditory canal, which opened widely enough for incus dislocation.- - - - - - - - - - ranking = 0.5keywords = bone (Clic here for more details about this article) |
