Schwannomas of the jugular foramen, originating from the glossopharyngeal nerve, vagus and accessory nerve represent approximately 0.17-0.72% of all intracranial tumor, and consists of 1.4-2.9% of all intracranial schwannomas. The clinical presentation of these tumors varies significantly according to originated nerve and it's growth pattern. Magnetic resonance(MR) image and temporal bone computed tomography(CT) scan have a major role for diagnosis of such tumor. The treatment of choice is total resection whenever possible. Generally, suboccipital approach is sufficient for the removal of the tumor, but in case with large size, combination of resection of petrous part of temporal bone with or without transection of sigmoid sinus is may be necessory. We have recently experienced one case of giant jugular foramen schwannoma and postoperative fatal complication in a 34-year-old male who was treated with combined posterior petrous and suboccipital approach with transection of sigmoid sinus

Objective : This study aimed to assess the surgical results of the intradural transpetrosectomy for petrous apex meningiomas (PAMs). In addition, we describe the methods and techniques used to expose and manage superior petrous vein and greater superficial petrosal nerve. Methods : The authors conducted a retrospective study of 16 patients with PAMs operated by the senior author via the intradural transpetrosectomy between February 2012 to May 2017. We reviewed patient data regarding the general characteristics, surgical technique and surgery-related outcomes and adopted a combined follow-up strategy of clinic and telephone contacts to evaluate postoperative complications. Results : Simpson grade I and II resection was performed in 10 out of 16 cases (62.5%), and grade III resection were reported in the remaining six cases (37.5%) with no resultant mortality. The mean Karnofsky Performance Status score was 85.6 preoperatively and improved to 91.9 postoperatively, with a mean follow-up period of 34.4 months (range, 6-66 months). Tumor recurrence was found in two patients and they underwent the second surgical operation. Conclusion : PAMs could be completely resected by the intradural transpetrosectomy with an improved survival rate and postoperative life quality. Superior petrous vein and greater superficial petrosal nerve should be managed properly in avoidance of postoperative complications. Finally, most meningioma inside cavernous sinus or adhered to brainstem could be totally removed without postoperative complications.

Although various methods had been reported for reanimination of facial nerve palsy, interposition nerve graft remains superior to other methods if there is a wide gap to be bridged. Dott described a excllent facial nerve reconstruction by sural nerve graft bypassing petrous bone. But his method needs two surgical fields and is performed in two stages. Authors desribe a traumatic facial nerve palsy treated by one stage facial nerve reconstruction that is performed in one surgical field by using a great auricular nerve interposition graft and bypass the petous bone.

Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Traumatic bilateral abducens nerve palsy is rare and is associated with intracranial, skull and cervical spine injuries. We report a case of bilateral abducens nerve palsy in a 40-month-old patient with a skull base fracture. The injury mechanism was associated with direct nerve injury caused by a right petrous bone fracture and indirect injury by frontal impact on the abducens nerve at the point of fixation to the petrous portion and Dorello's canal. The emergency physician should be aware of injuries and the mechanism of abducens nerve palsy in head trauma.

Facial nerve schwannomas are uncommon tumors. A 40-year-old female presented with left-side facial weakness. Computed tomography[CT] imaging showed a $3\;{\times}\;2cm$ lesion on the posterior portion of the left middle cranial fossa. The mass abutted the anterior aspect of the left petrous bone with a wide erosive change involving the area of the left facial nerve ganglion [geniculate ganglion]. A well-circumscribed extra-axial mass was seen on magnetic resonance imaging[MRI]. The tumor was completely removed through subtemporal approach and the patient was discharged without additional neurological deficit. This rare case is discussed and a review of the relevant literature is presented.

This report describes a case of diffuse neurofibroma[DNF] that presented with spontaneous intratumoral hemorrhage. A 31-year-old man with cutaneous manifestations typical of neurofibromatosis type 1[NF1] was referred to hospital with a progressively expanding scalp swelling. Magnetic resonance imaging[MRI] showed an acute hematoma surrounded by a dense mass on the parietooccipital scalp. Plain skull radiographs and a computed tomography[CT] scan revealed bony defects in the occipital bone around the lambdoid suture and the skull base, including the sphenoid and petrous bones. The tumor extended to the upper cervical region and infiltrated through the fascia of the musculature. The tumor and adjacent soft tissue were highly vascular, which made surgical resection difficult. We describe the clinical, radiological and pathological features of this patient md discuss the surgical methods used to avoid a life-threatening hemorrhage during surgery.

The authors report a case of cholesterol granuloma in the sphoid sinus in 54-year old woman, which is probably the first report of cholesterol granuloma arising primarily in the sphenoid sinus apart from the petrous bone. The initial clinical presentations were unilateral decreased visual acuity and facial sensory change. The mass was removed totally via transsphenoidal route and the pathological examination revealed cholesterol clefts and chronic granulomatous changes. The differences between the present case and the previous reports are discussed.

This study was performed to observe the secondary images and to analyse the relationships between the primary and secondary images in panoramic radiograph. Using the Moritta's Panex-EC panoramic x-ray machine and the human dry skull, the author analysed 17 radiographs which were selected from 65 radiographs of the dry skull that attached the radiopaque materials, and the attached regions of the radiopaque materials were the normal anatomical structures which were important and selected as a regions for the evaluation of the secondary images effectively. The results were as follows; 1. The cervical vertebrae showed three images. The midline image was the most distorted and less clear, and bilateral images were slightly superimposed over the posterior border of the mandibular ramus. 2. In mandible, the secondary image of the posterior border of the ramus was superimposed on the opposite ramus region, and this image was elongated from the anterior border of the ramus to the lateral side of the posterior border of the ramus. The secondary image of the condyle was observed on the upper area of the coronoid process, the sigmoid notch and the condyle in opposite side. 3. In maxilla, the posterior region of the hard palate showed the secondary image on the lower part of the nasal cavity and the medial wall of the maxillary sinus. 4. The primary images of the occipital condyle and the mastoid process appeared on the same region, and only the secondary image of the occipital condyle was observed symmetrically on the opposite side with similar shape to the primary one. 5. In the cranial base, the anatomical structures of the midsagittal portions like a inferior border of the frontal sinus, sella turcica, inferior borderr of the sphenoid sinus and inferior border of the posterior part of the occipital bone showed the simillar shape between the primary and secondary images symmetrically. 6. The petrous portion of the temporal bone showed the secondary image on the lateral side of the sella-turcica, and the secondary images of the posterior border of lesser wing, superior border of greater wing of the sphenoid bone and posterior border were observed on the anterior-superior and inferior region of the sella-turcica.
