We paid our attention to the MPRAGE (Magnetization Prepared Rapid Acquisition with Gradient Echo) method on high resolving power MRI. By the MPRAGE method, low intensity was observed in these lesions of all cases. This result suggested that the plaque in petrous portion was a fibrous plaque. This method ...

As solid as a rock - the petrous bone as a source of DNA for the comparison of CE-and MPS-based forensic identification of challenging cranial bones
The invention and development of next or second generation sequencing methods has resulted in a dramatic transformation of ancient DNA research and allowed shotgun sequencing of entire genomes from fossil specimens. However, although there are exceptions, most fossil specimens contain only low (~ 1% or less) percentages of endogenous DNA. The only skeletal element for which a systematically higher endogenous DNA content compared to other skeletal elements has been shown is the petrous part of the temporal bone. In this study we investigate whether (a) different parts of the petrous bone of archaeological human specimens give different percentages of endogenous DNA yields, (b) there are significant differences in average DNA read lengths, damage patterns and total DNA concentration, and (c) it is possible to obtain endogenous ancient DNA from petrous bones from hot environments. We carried out intra-petrous comparisons for ten petrous bones from specimens from Holocene archaeological contexts ...

The largest of all the cranial nerves, the trigeminal nerve gives rise to a small motor root originating in the motor nucleus within the pons and medulla oblongata, and a larger sensory root which finds its origin in the anterior aspect of the pons. The nerve travels forward from the posterior cranial fossa to the petrous portion of the temporal bone within the middle cranial fossa. Here, the sensory root forms the trigeminal (semilunar or gasserian) ganglion situated within Meckels cavity on the anterior surface of the petrous portion of the temporal bone. The ganglia are paired, one innervating each side of the face. The sensory root of the trigeminal nerve gives rise to the ophthalmic division (V1), the maxillary division (V2), and the mandibular division (V3) from the ...
I was diagnosed with a petrous apex cholesteatoma in June this year after spending a week in hospital. I had a battery of tests as well as numerous CT and MRI scans. My symptoms include extreme headaches, nausea, pins and needles and numbness to the left side of my face, weeping left eye and sometimes blurred vision. It is difficult to perform the normal daily functions when I get the symptoms. The petrous apex is located in the center of the head approximately 2-3 inches from the outside of your ear. It is one of the most inaccessible areas to reach in the skull. The petrous apex can have lesions and tumors within it. The most common type of lesion is a petrous apex fluid filled cyst. The surgery is very extensive and rarely performed in South Africa as this is an extremely rare condition. The area that it is located in, requires you to go in between the carotid artery, jugular vein and cochlear. Between 1983 and 2004, 43 patients were treated in USA. There is a Prof. Marco Caversaccio in ...

Should the superior petrosal vein be sacrificed during surgery for trigeminal neuralgia? What are the implications of its obliteration?
During a median follow-up of 72 months, neurological status improved in 44 patients (26%), remained stable in 98 (58%), and worsened in 26 (15%). Tumor volume decreased in 78 patients (46%), remained stable in 74 (44%), and increased in 16 (10%), all of whom were subjected to additional management strategies. Overall 5- and 10-year progression-free survival rates were 91 and 86%, respectively. Patients followed up for at least 10 years (31 patients) had tumor and symptom control rates of 97 and 94%, respectively. Eight patients had repeat radiosurgery, 4 underwent delayed resection, and 4 had fractionated radiation therapy. Cerebrospinal fluid diversion was performed in 7 patients (4%). Significant risk factors for tumor progression were a tumor volume ≥ 8 cm3 (p = 0.001) and male sex (p = 0.02). ...
MATERIALS AND METHODS: Forty-four consecutive patients who underwent contrast-enhanced CT using 320-row area detector CT and contrast-enhanced MR imaging for nasopharyngeal carcinoma staging between April 2012 and November 2017 were enrolled in this retrospective study. Bone subtraction iodine images were generated by subtracting pre- and postcontrast volume scans using a high-resolution deformable registration algorithm. Two blinded observers evaluated skull base invasion at multiple sites (sphenoid body, clivus, bilateral base of the pterygoid process, and petrous bone) using conventional CT images alone or in combination with bone subtraction iodine images. Examination of MR and CT images by an experienced neuroradiologist was the reference standard for evaluating sensitivity, specificity, and area under the receiver operating characteristic curve. ...

Abstract: The arrival of farming in Europe around 8,500 years ago necessitated adaptation to new environments, pathogens, diets, and social organizations. While indirect evidence of adaptation can be detected in patterns of genetic variation in present-day people, ancient DNA makes it possible to witness selection directly by analyzing samples from populations before, during and after adaptation events. Here we report the first genome-wide scan for selection using ancient DNA, capitalizing on the largest genome-wide dataset yet assembled: 230 West Eurasians dating to between 6500 and 1000 BCE, including 163 with newly reported data. The new samples include the first genome-wide data from the Anatolian Neolithic culture, who we show were members of the population that was the source of Europes first farmers, and whose genetic material we extracted by focusing on the DNA-rich petrous bone. We identify genome-wide significant signatures of selection at loci associated with diet, pigmentation and ...

Background: The Trigemino-cardiac reflex (TCR) has been studied as a phenomenon including bradycardia, arterial hypotension, apnea and gastric hypermotility during manipulation of the peripheral or central parts of the trigeminal nerve.Case presentation: We report a case of a 26-year-old man undergoing surgery for a skull base extra axial tumor in right petrous bone suspected to metastasis of a previous renal cell carcinoma which had been treated four years ago. The patient presented with continuous and unilateral headache and difficulty in swallowing, sensory neural hearing loss, nasal speech and tongue deviation to left side. He underwent general anesthesia with standard monitoring and total intravenous anesthetic technique. The first episode of sudden onset bradycardia and hypotension related to surgical manipulation was detected intraoperatively in which the heart rate spontaneously returned to normal level once the surgical manipulation stopped. However, it repeated several times by ...
PURPOSE: To study the association between petrous carotid canal (PCC) and internal carotid artery (ICA) stenoses in patients with malignant osteopetrosis. MATERIALS AND METHODS: Mean and minimum PCC diameters obtained from cranial computed tomographic (CT) scans in 20 patients were compared with similar measurements in 52 control subjects. ICA caliber, evaluated with magnetic resonance (MR) arteriography, was correlated with age and PCC dimensions. RESULTS: There was a statistically significant difference between patient and control PCC diameters. There was a strong positive correlation between age and PCC diameter in the control subjects, but only a weakly positive correlation in the patients. One or both ICAs were stenotic on all patient MR arteriograms. MR angiographic stenosis grade correlated positively with age but not with PCC diameters. CONCLUSION: PCC and ICA stenoses occur frequently in patients with malignant osteopetrosis. Bony overgrowth or a persistent fetal state may produce the ...
BACKGROUND: Intracranial aneurysms are the leading cause of nontraumatic subarachnoid hemorrhage and are most commonly associated with the anterior cerebral artery (ACA) and anterior communicating artery complex. We describe the presentation and management of a 27-year-old man with concurrent bilateral A1-2 junction aneurysms and fusiform intraorbital ophthalmic artery (OA) aneurysms.. CASE DESCRIPTION: A 27-year-old man with no past medical history presented with 3 months of headaches. Imaging showed a large dysplastic left A1-2 junction aneurysm and a smaller saccular right A1-2 junction aneurysm, with potentially adherent domes. Two fusiform aneurysms of the intraorbital segment of the left OA were also identified. The patient underwent coil-assisted pipeline embolization of the left A1-A2 aneurysm, with complete obliteration and reconstitution of the normal parent vessel. The patient underwent coil embolization of the right A1-2 aneurysm 3 weeks later, which was found to have grown ...
This syndrome has been known to occur due to spread of ear infection to involve air cells around petrous apex. It is hence also known as Petrous apex syndrome / Petrous apicitis. Infection & inflammation of petrous apex involves 6th cranial nerve at the Dorellos canal and 5th cranial nerve in the Meckels cave. Meckels cave lies close to Dorellos canal. Retro orbital pain is caused due to the involvement of trigeminal ganglion (Gessarian ganglion) at the level of Meckels cave. ...

A case of a 71-year-old male patient is presented with extensive invasion of middle and posterior fossae, with nearly complete destruction of the petrous bone, involving cerebellopontine angle and cranial nerves by recurrent basal cell carcinoma of the auricular region on the right side. The clinical manifestation was cerebrospinal fluid otorrhoea, facial nerve palsy and trigeminal nerve impairment with hypoesthesia. The patient underwent surgery by combined retroauricular and temporal approach to the skull base. Adjuvant radiation of residual tumor and former tumor recurrence region was performed. MRI studies performed annually show no progress of the tumor. Our patient reports a good quality of life without new neurological deficits 6 years after surgery. Attention should be paid to the malignant nature of ...
THE LABYRINTH AND THE EIGHTH NERVE 397 however, the eighth nerve signs are usually less evident than the other neuro- logical signs. 1. Syphilitic neurolabyrinthitis should be diagnosed by the history of syphilitic infection and the serological reactions of the blood and cerebro- spinal fluid. 2. Neuritis due to toxaemia may be eliminated by a careful history of the cases and thorough physical examination. Such cases do not show complete deafness and loss of vestibular reaction. 3. Haemorrhage into the labyrinth in the bleeding diseases should be excluded by an examination of the blood. Fig. 212.

Bast TH. Osteogenesis of the human periotic capsule. (1929) Arch Otolaryngol. 10(5): 459-471 Draft only The petrous portion of the temporal bone and in particular the otic capsule, which stands alone in the category of bones, is of interest from a purely embryologic and anatomic standpoint because of its unique structure, both gross and histologic; but a thorough knowledge of the development and structure of this bone may prove of importance in throwing light on the mystery surrounding otosclerosis and its supposed relation to the dreaded disease, progressive deafness. The bony otic capsule which houses the sense organs of hearing and equilibrium differs from other bones as to form, structure and function. Bones are conventionally classified as long or cartilage bones and flat or membrane bones. While the otic capsule is classified with cartilage bones, it is neither a long bone nor a flat bone. It is a capsular bone. The cranium is also a bony box, but it is made up of a number ...

It arises from the inferior ganglion of the glossopharyngeal nerve, and ascends to the tympanic cavity through a small canal, the inferior tympanic canaliculus, on the under surface of the petrous portion of the temporal bone on the ridge which separates the carotid canal from the jugular fossa. In the tympanic cavity it divides into branches which form the tympanic plexus and are contained in grooves upon the surface of the promontory. The tympanic nerve contains both sensory and parasympathetic axons: ...

Sinus infections are an inflammation of the lining tissue of the sinus and their drainage pathways. Typical symptoms include headache- pressure like pain of the face, forehead, cheeks, and pain around or behind the eyes, dental pain, and tenderness of the face. Some people experience loss of smell, bad breath, cough, fever, sore throat, and discolored nasal drainage. Some patients experience fatigue and malaise.. The causes of sinusitis are the common upper respiratory viruses, allergies to pollens and mold, environmental irritants like air pollution, or tobacco smoke. Blockage like a deviated septum, polyps, or narrow anatomic drainage pathways can also cause sinusitis. If the mucus produced by the sinuses does not drain into the nose it will eventually stagnate and become infected with viruses and bacteria. Sinus infections are categorized as an acute infection, recurrent infections, and chronic infections.. ...

N1 - Copyright: Copyright 2018 Elsevier B.V., All rights reserved.. PY - 2005/7. Y1 - 2005/7. N2 - INTRODUCTION: To avoid any morbidity occuring after surgery for petroclival meningioma, we use the following treatment strategy: (1) the tumor should be left undetached in cases where there is no CSF space between the tumor and the surrounding structures to avoid a new deficit, (2) the residual volume should be reduced to less than 20 ml, small enough for radiosurgery. The result of our strategy presented. METHODS: During the past 10 years, we treated 13 patients with petroclival meningioma. The tumor volume ranged from 1.0 ml to 70 ml. 11 patients had neurological deficits preoperatively. 11 patients underwent an anterior petrosal approach while 2 patients underwent a far lateral approach according to the tumor ...
The middle fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest.It is bounded in front by the posterior margins of the lesser wings of the sphenoid bone, the anterior clinoid processes, and the ridge forming the anterior margin of the chiasmatic groove; behind, by the superior angles of the petrous portions of the temporal bones and the dorsum sellæ; laterally by the temporal squamæ, sphenoidal angles of the parietals, and greater wings of the sphenoid. It is traversed by the squamosal, sphenoparietal, sphenosquamosal, and sphenopetrosal sutures. It houses the temporal lobes of the brain. ...

The CT examination when done showed a small epidural enhanced left petrous collection with downward extension to the superior pharyngeal mucosal space, extensive destruction of the ipsilateral petrous apex and opacification of the tympanic cavity and mastoid air cells, with mastoidal sclerosis. The MRI showed the left petrous apex lesion, which was hypointense as seen on T1-weighted images, hyperintense when seen on T2-weighted images and enhanced by using gadolinium, and also demonstrated the small infracranial extension. CT and MRI are highly sensitive in detecting petrous apex lesions. As in this case, they permit the identification of apical osteomyelitis surrounded by a phlegmon collection. When the petrous apicitis is large enough, it can injure the VI cranial nerve where it passes through the petrous apex in Dorellos canal, on its way to the orbit via the cavernous sinus. Then, the patient presents with the symptoms of Gradenigos syndrome: otitis media, deep facial pain along the ...

Meningiomas were centered over the cerebellopontine angle in 43 patients (17%), the clivus in 40 (16%), the petroclival region in 28 (11%), the petrous region in 6 (2%), and the parasellar region in 138 (54%). The median duration of follow-up was 6.5 years (range 2-18 years). The mean preradiosurgery tumor volume was 5.0 cm3 (range 0.3-54.8 cm3).. At most recent follow-up, 220 patients (86%) displayed either no change or a decrease in tumor volume, and 35 (14%) displayed an increase in volume.

It is has branches located on both the left and right side of the body, and each branch will initially travel down to produce the auricular nerve. This branch supplies the external acoustic meatus or the ear canal. The branches also supply innervation to the pharynx. From here the right and left branches of the vagus nerve will enter the thorax to supply the organs located within the thorax and eventually down to the abdomen. This nerve will therefore innervate all the critical organs within this area except the adrenal gland, descending colon, rectum, and anus. Based on this it is possible to see the importance of this nerve in controlling the heart rate, digesting food, and regulating breathing. Thus there are quite a number of presentations in the symptoms of vagus nerve damage ...

From the course of the lymphatic vessels it is evident that the breast cannot be divided into functionally separate segments. According to the lymphatic map of the breast, one can assume that in carcinoma of the breast it is the lymphatic drainage and not the localization of the tumor that plays a primary role in the development of metastases. One cannot ignore the existence of alternative drainage pathways of the breast, but their role in the beginning of dissemination of tumor cells in comparison with the axilla is negligible. Subdermal administration of Patent Blau is a reliable and effective method of visualizing lymphatic vessels and the draining lymph nodes of the breast. Due to the meandering course of lymphatics in the breast, we cannot understimate the role of radiation therapy after breast conserving surgery ...

There was a discussion about different formats, and it never got anywhere, Donnie Walsh, the Knicks president, said Monday.. The Memphis Commercial Appeal reported last week on its web site that the Knicks were weighing a swap of Randolph for forward Darko Milicic and guard Marko Jaric. According to the report, the only sticking point was whether the Knicks would agree to pay some of the deferred salary in Randolphs contract. He is owed $48 million over the next three seasons. However, others involved in the talks said there was more to the deal than had been reported.. It was a conversation I had with these guys a month ago, Walsh said. We havent talked recently. For some reason, it was in the Memphis press and everyone in New York acts like its imminent.. Asked if a deal with Memphis was still possible, Walsh said, I cant say anything is over, but he said there was no active proposal on the table. Theyre dormant, he said of the talks ...
