In this report, we describe the incidental finding of an oropharyngeal mass in a patient who presented with a chief complaint of temporomandibular pain. The patient was initially evaluated by an otorhinolaryngologist for complaints of headaches, earache, and sinus congestion. Due to worsening headaches and trismus, he was further referred for the management of temporomandibular disorder. The clinical evaluation was uneventful except for limited mouth opening (trismus). An advanced radiological evaluation using magnetic resonance imaging revealed a mass in the nasopharyngeal/oropharyngeal region. The mass occupied the masticatory space and extended superioinferiorly from the skull base to the mandible. A diagnostic biopsy of the lesion revealed a long­standing human papilloma virus (HPV­16)­positive squamous cell carcinoma of the oropharynx. This case illustrates the need for the timely radiological evaluation of seemingly innocuous orofacial pain.

There is a difficulty in complete removal of tumor developing at the parapharyngeal space or infratemporal space where they are just under the skull base. We have experienced 3 cases of malignant tumors and 5 cases of benign tumors arising from the parapharyngeal spaces and/or infratemporal space since 1976. We hereby present 8 cases of primary tumors arising in these spaces with a review of anatomical relationship between above spaces, the characteristic symptoms, diagnostic technics, and surgical approaches which should be considered in their management.

This study was undertaken to investigate the values of the cephalometric standards of Korean children which consisted of 57 boys and 61 girls with normal occlusion and harmony of the facial musculature. The following conclusions were obtained. 1) The relatively vertical inclination of nasal bone and flat contour of the frontal bone contribute to the flattening of the upper face. 2) Slight lack of chin prominence characterizes the lower face while procumbent incisors and their alveolar bone dominate the middle face. 3) A caudal skull base inclination is probably the most specific feature for Korean.

Pencils are common instruments for children to use and play with. This report describes an unusual penetrating orbitocranial injury in a 5-year-old girl who was struck in her facewith a pencil. She was holding it at a desk, and her friend pushed her back. The pencil penetrated the left lower eyelid and went deep into the right frontal lobe through the base of the skull. It was removed at the emergency room, after which brain CT was performed to detect the development of an intracranial hematoma. No complications occurred after conservative management with antibiotics and an antiepileptic drug. Pencils can be hazardous to children, and a penetrating head injury with a pencil may be managed without cranial surgery.

Objective: Jugular foramen schwannomas are uncommon pathological conditions. This article is constituted for screening these tumors in a wide perspective. Materials: One-hundred-and-ninty-nine patients published in 19 articles between 1984 to 2007 years was collected from Medline/Index Medicus. Results: The series consist of 83 male and 98 female. The mean age of 199 operated patients was 40.4 years. The lesion located on the right side in 32 patients and on the left side in 60 patients. The most common presenting clinical symptoms were hearing loss, tinnitus, disphagia, ataxia, and hoarseness. Complete tumor removal was achieved in 159 patients. In fourteen patients tumor reappeared unexpectedly. The tumor was thought to originate from the glossopharyngeal nerve in forty seven cases; vagal nerve in twenty six cases; and cranial accessory nerve in eleven cases. The most common postoperative complications were lower cranial nerve palsy and facial nerve palsy. Cerebrospinal fluid leakage, meningitis, aspiration pneumonia and mastoiditis were seen as other complications. Conclusion: This review shows that jugular foramen schwannomas still have prominently high morbidity and those complications caused by postoperative lower cranial nerve injury are life threat.

We describe a case of intracranial carotid artery occlusion due to penetrating craniofacial injury by high velocity foreign body that was relieved by decompressive surgery. A 46-year-old man presented with a penetrating wound to his face. A piece of an electric angular grinder disc became lodged in the anterior skull base. Computed tomography revealed that the disc had penetrated the unilateral paraclinoid and suprasellar areas without flow of the intracranial carotid artery on the lesion side. The cavernous sinus was also compromised. Removal of the anterior clinoid process reopened the carotid blood flow, and the injection of glue into the cavernous sinus restored complete hemostasis during extraction of the fragment from the face. Digital subtraction angiography revealed complete recanalization of the carotid artery without any evidence of dissection. Accurate diagnosis regarding the extent of the compromised structures and urgent decompressive surgery with adequate hemostasis minimized the severity of penetrating damage in our patient.

Central nervous system[CNS] involvement of acute lymphoblastic leukemia may occur. However, CNS involvement as a first manifestation of leukemia is very rare. An 8-year-old girl complained of a backache after playing in the water. Neurological examination detected progressing paraparesis. Magnetic resonance imaging[MRI] of the thoracolumbar spine showed a well-circumscribed homogeneous posterior extradural mass lesion extending from T7 to T9. MRI of the brain showed diffused fatty marrow replacement of the calvarium and the skull base. We report a patient with epidural Burkitt's lymphoma of the thoracic and lumbar vertebra causing compression of the spinal cord after pathologic evaluation. The tumor consisted mainly of lymphoblastic cells, which were identical to those originally seen in the bone marrow aspiration and biopsy. After decompressive laminectomy she began consolidation chemotherapy.

The authors describe the experience with the interactive image-guided Zeiss SMN system, which has been applied to 20 patients with various intracranial lesions during one year. Preoperative radiologic evaluation was CT scan in 6 cases, MRI in 14 cases. In all except one case, average fiducial registration errors were less than 2mm. There was no statistical difference in registration error between CT and MR image. This system considered to be relatively stable with respect to soft and hardware. Also it was useful for the designing of the scalp incision and bone flap and assessing the extent of resection in tumors, especially in gliomas. Moreover, it was helpful to evaluate complex surgical anatomy in skull base surgery.

A sphenoid mucocele often presents late due to its deep seated anatomical site. And it has varied presentation due to its loose relationship to the cavernous sinus and the base of the skull. We describe a case of large sphenoid sinus mucocele. A middle aged old man suddenly developed third cranial nerve palsy. Brain imaging study revealed an isolated sphenoid sinus mucocele, compressing right cavernous sinus. Endoscopic marsupialization of the mucocele via transnasal approach led to complete resolution of the third cranial nerve palsy. Involvement of the third cranial nerve in isolated mucocele is rare but important neurosurgical implications which must be excluded. In addition, proper and timely treatment must be performed to avoid permanent neurologic deficit.

An uncommon case of a patient with recurrent mandibular ameloblastoma involving various adjacent soft tissues is presented with plain film radiography, computed tomography and magnetic resonance imaging (MRI) and bone scan. The tumor involved mandible and eroded several bones including foramen ovale. This case shows that although an ameloblastoma primarily affect mandible, exact radiographic evaluation of tumor extent will assist the surgeon in the progress of rational approaches to the management of ameloblastoma.
