The temporal bone is one of the bones in the skull. Everyone has two of these bones, one on either side of the skull, with the bones comprising part of the sides and base of the skull. These bones are closely involved in the anatomy of the ear, and they house a number of anatomical structures of importance Radiology department of the University Medical Centre of Utrecht, the Netherlands. The aim of this presentation is to demonstrate imaging findings of common diseases of the temporal bone. CT is the imaging modality of choice for most of the pathologic conditions of the.. . Longitudinal fractures generally spare the inner ear, which is more often breached by transverse fractures. However, many temporal bone fractures are neither longitudinal nor transverse and a comprehensive description of the structures which are crossed by the fracture is needed The temporal bone (latin: os temporale) is a paired bone situated at the lateral side and base of the skull. The temporal bone features important structures of the vestibulocochlear apparatus, including the external acoustic meatus, the tympanic cavity and the structures of the inner ear Overview of Temporal Bone Tumors. Tumors of the ear area are generally rare. Tumors of the ear can be divided into benign or cancerous. The benign tumors can occur from the skin (cysts or ceruminoma) or the lining of the space behind the ear drum (e.g., middle ear adenoma, glomus tumor, facial neuroma or schwannoma among others). Cancer of the.
The temporal bone (os temporale; L., the temple) forms portions of the sides and base of the skull. 1. 2. It is anatomically divided into four regions called the squamous, mastoid, temporal, and petrous parts Each articulates with the zygomatic bone (zygomaticotemporal suture), sphenoid bone (sphenosquamosal suture), parietal bone (parietosquamous suture), and occipital bone (occipitomastoid suture).22-24 Understanding the anatomy of the temporal bone is critical to a number of open skull base approaches.26 A number of critical neurovascular structures, namely, the lower seven cranial nerves and. Temporal bone. Temporal bone, by the way, is the most complex bone in our body. It is embryologically formed by the fusion of 11 ossification centers * that incorporate the peripheral part of the audio-vestibular system and provide all necessary channels and openings for multiple cranial nerves & blood vessels passing through it. * Navjot Singh From Wikimedia Commons, the free media repository.

We have created an atlas of the temporal bone which is an educational tool for studying the normal anatomy of the petrous bone based on an MDCT exam of the axial and coronal of the ear and petrous bone. Anatomical structures are visible as interactive labeled images
Paraganglioma is the second most common tumor involving the temporal bone . Glomus tumors in the temporal bone region arise from the jugulotympanic paraganglia along the nerves of Jacobson and Arnold (tympanic branch of the glossopharyngeal nerve and auricular branch of the vagus nerve, respectively) This will diagnose temporal bone fractures and associated intracranial pathology. It is important to note whether fractures involve the otic capsule or brain parenchyma. By reference to the long axis of the petrous temporal bone (ie in the plane of the ear canal), 80% of temporal bone fractures are longitudinal (from lateral blows) and 20%.
Temporal Bone Imaging Technique. Paul A. Caruso, Jennifer L. Smullen, Robert Liu, Mary Beth Cunnane, Hugh D. Curtin. This chapter on the technique for imaging the temporal bone is a practical how to written in two parts. In the first part, we explain how to image the temporal bone: how to run the hardware and obtain the images 1. Petrous part: It's the most challenging (rock like) part of the temporal bone and includes inside it: internal ear, middle ear and mastoid antrum, which it safely shields. It also includes carotid canal for internal carotid artery. The petrous part has a shape of a 3 dimensional pyramid Temporal bone injury is a condition associated with significant morbidity, the prompt recognition of which may aid recovery. While many blunt injuries may be managed conservatively, penetrating fractures, such as gunshot wounds, warrant a lower threshold for surgical intervention. 1. Ishman SL, Friedland DR The temporal bone ( os temporale; L., the temple) forms portions of the sides and base of the skull. 1. 2. It is anatomically divided into four regions called the squamous, mastoid, temporal, and petrous parts TRAUMA Historically, temporal bone fractures were classified into two main categories, longitudinal and transverse, on the basis of the fracture plane relative to the long axis of the petrous bone. It is now generally recognized that temporal bone fractures may be complex with mixed features of both longitudinal and transverse fractures
Temporal bone. The middle ear consists of the tympanic cavity and the antrum. The antrum is a large aircell superior and posterior to the tympanic cavity and connected to the tympanic cavity via the aditus ad antrum. The epitympanum or attic is the upper portion of the tympanic cavity above the tympanic membrane, and contains the head of the. Temporal bone:Facial nerve. The facial nerve carries sensory, secremotor and motor fibres to the face. It emerges at the lower border of the pons above the olive. Three brainstem nuclei contribute to the facial nerve: one motor, one secretomotor, and one sensory: facial nerve motor nucleus in the pons: as the motor fibres of the facial nerve.
The temporal bone is ideally suited for low-dose CT because of the high intrinsic contrast of the imaged structures. 4 As a consequence, low-dose temporal bone CT protocols for adults have been described before. 4,5 However, there is no systematic evaluation of any pediatric low-dose temporal bone CT protocol in the literature Ear and Temporal Bone Cancer Paul W. Gidley The external ear is a relatively common location for skin cancers. The external ears are susceptible to sun exposure accounting for the relatively high rate of skin cancer occurrence. Squamous cell carcinoma (SCC) of the outer ear is notorious for a relatively high metastatic rate and Temporal bone fracture is what I have on the left side of my head, next to my ear. That must be where I hit the ground real hard when I fainted on March 31. The link below seems to have some good information about it, including my symptoms of vertigo and cranial nerve damage as a result of a temporal bone fracture Fibrous dysplasia involving the temporal bones has been well documented in the literature. 8,10,24,35-38 With temporal bone involvement, the primary indications for surgery are canal stenosis leading to hearing loss, as seen in 2 patients in this study, and the presence of a cholesteatoma behind a stenotic external auditory canal. 8,24 During. A lateral temporal bone resection is typically done if the tumor is in the bony part of the ear or within the inner two-thirds of the ear canal. A novel procedure developed by Dr. Djalilian is to remove the lateral portion of the ear canal without disturbing the ear drum and has been found to be equal in controlling disease than the traditional lateral temporal bone resection
Temporal bone anatomy is arguably the most complex anatomy in the human body.

The Temporal Bone. The temporal bone comprises five distinct sections attached at bony sutures, termed the squamous portion, the mastoid portion, the tympanic portion, the petrous portion, and the zygomatic process. Numerous irregularities create the important landmarks on the lateral surface of the temporal bone The temporal bone (the skull bone containing part of the ear canal, the middle ear, and the inner ear) can be fractured, usually by a blow to the head. A temporal bone fracture may cause facial paralysis, hearing loss, bruising behind the ear, and bleeding from the ear. Doctors use computed tomography (CT) to diagnose temporal bone fractures Temporal bone:Floor & roof features, windows & foramina. The middle ear, six sided cavity, situated between the external ear (divided from each other by the tympanic membrane) and the inner ear (divided by the medial wall of the tympanic cavity). It is an air space in the temporal bone and contains three auditory ossicle that mechanically.
