Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Cranial Bones: Superior and Posterior View

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Sutures of the Skull

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Area of Science:

Radiology
Otolaryngology
Neurosurgery

Background:

The temporal bone's complex anatomy presents challenges for postoperative imaging evaluation.
Surgical approaches include tympanoplasty, mastoidectomy, and cerebellopontine angle/internal auditory canal (IAC) procedures, often combined.

Purpose of the Study:

To review expected imaging findings and complications following common temporal bone surgeries.
To guide radiologists and surgeons in interpreting postoperative imaging.

Main Methods:

Review of imaging techniques (CT and MRI) and their applications in temporal bone surgery.
Correlation of imaging findings with specific surgical procedures and potential complications.

Main Results:

CT is preferred for assessing the conductive mechanism, graft/prosthesis integrity, and surgical cavity aeration.
MRI, particularly contrast-enhanced fat-suppressed sequences, is optimal for IAC procedures and soft tissue evaluation.
Diffusion-weighted imaging aids in detecting cholesteatoma.

Conclusions:

Understanding expected imaging findings is crucial for accurate postoperative assessment of temporal bone surgery.
CT and MRI play complementary roles in evaluating surgical outcomes, complications, and disease recurrence.
