“…MRI is an established technique which is becoming increasingly important in the diagnosis, treatment planning and follow-up of ENT tumours. The soft tissue contrast demonstrated by MRI is superior to that obtained with CT scanning (Langnickel and Held, 1992).…”

Only a small number of cases of bilateral carcinomas of the external ear canal have been described in the literature. We present the first case of a 72 year old male patient with a bilateral squamous cell carcinoma of the external ear canal at a very early stage. A computed tomography of the temporal bone revealed a well-pneumatized mastoid on both sides. Both external ear canals were filled with soft tissue without radiological signs of destruction of the adjacent bone. The carcinomas of the external ear canal were surgically removed using a canal-wall down technique and a selective neck dissection of regions II-IV. Histology confirmed a well differentiated squamous cell carcinoma of the external ear canal without lymph node metastasis on both sides (TNM classification: pT1 G2 N0 M0 R0). Bilateral radiation therapy with 59.4 Gy resulted in stenosis of both ear canals. Hearing rehabilitation was achieved with bone conductive hearing glasses. Diagnosis und therapy of bilateral external ear carcinomas are presented and discussed.

CT is accepted as the gold standard for pathological-anatomical evaluation of paranasal sinus disease, CT is especially considered an obligatory part of planning surgical procedures. Indications for paranasal sinus CT include trauma, malignant disease, and chronic sinusitis, which accounts for the major part of examinations. Due to the benign character of the disease and the relatively moderate age of the patients involved, the radiation dose of paranasal sinus CT plays an important role. The use of a low-dose spiral CT technique and the reformation of coronal images out of the axial CT data instead of an additional direct coronal scan allow the effective dose of paranasal sinus CT to be reduced to the order of a chest radiogram. MRI is the preferred imaging modality in malignant disease or complications of inflammatory sinus disease that extend beyond the limits of the paranasal sinuses. The clinical value of other imaging modalities, including plain film radiography, ultrasound, or scintigraphy, is limited to special indications.
