The introduction of cross-section imaging, CT and MRI has hugely expanded the scope and ability of head and neck radiology to recognize and assess disease.

Plain radiographs and conventional tomography have virtually no place in the assessment of disease in the modern setting.

Contrast medium studies still have a major role in the assessment of disorders of swallowing.

Ultrasound in skilled hands is fast becoming the first line investigation for many neck conditions.

Role of Radiology:-

Detection of disease . (Modern ENT clinics are equipped with advanced audiological and electrophysiological equipments already)

Pathological characterization if possible. (FNAC)

For ENT surgeon –to know the extent of disease.

• Acquired deafness and tinnitus are common problems and patients should be carefully selected for imaging.

• Conductive deafness is best imaged with HRCT and • Sensorineural deafness with T2 weighted 3D MRI.

• Common causes of conductive deafness; cholesteatoma, ossicular fixation, ossicular erosion, traumatic subluxations and dislocations and otospongiosis.

• Investigation of acquired sensorineural deafness mainly revolves around excluding vestibular schwannoma and differentiating this from other causes of CP angle masses.
