Обзор

This study aimed to identify the prevalence of normal variations of temporal bone anatomy on high-resolution CT imaging and discuss their clinical importance

Подробное описание

The temporal bone has a difficult anatomical structure for otologists and radiologists.In addition to its anatomical complexity, variations in the three-dimensional relationships of structures within the temporal bone need additional attention. The assessment of these relationships is of primary importance in diagnosis, treatment planning, and preoperative management. High-resolution computed tomography (CT) helps locate the anatomical structures within the temporal bone. Preoperative knowledge of the courses of vascular structures within and neighboring the temporal bone is of primary importance. If not detected preoperatively, variations in the localizations of the vascular structures may lead to disastrous consequences during surgery. The surgically important positions of the vascular structures that are generally accepted as normal variants are, High-resolution CT has made it possible for clinicians to study middle- and inner-ear pathology before undertaking surgery. This is particularly useful when the disease has altered the anatomy, resulting in complications such as a lateral canal fistula and facial canal or tegmen erosion there have been several studies reporting the value of high-resolution CT for investigations of cholesteatoma, temporal bone tumors, and congenital anomalies studies on the prevalence of normal anatomical variations of the temporal bone as the use of high-resolution CT imaging for temporal bone investigations is now widespread, it is necessary for the investigating otologist to be aware of common anatomical variations and their clinical implications

Вмешательства

  • Лучевая терапия CT
    Patients with unilateral ear pathology will be randomly assigned to do CT temporal bone, The presence of five variants was determined. These variants were: a high dehiscent jugular bulb, an anteriorly located sigmoid sinus, a deep sinus tympani, an enlarged cochlear aqueduct, and an enlarged internal auditory meatus (IAM). A GE LightSpeed 16, four-slice, helical CT scanner (Fairfield, Connecticut, USA) was used for all patients. The scan parameters were as follows: 1 mm slices, smart Ma (50-250
