Question:

Indications for primary non contrast enhanced CT evaluation of the temporal bone include:
1. EAC stenosis
2. Cholesteatoma
3. Aural dyplsasia
4. Conductive hearing loss
5. Trauma





Answer:

The correct answers for the question " Indications for primary non contrast enhanced CT evaluation of the temporal bone include:" are:

1. EAC stenosis

3. Aural dyplsasia

4. Conductive hearing loss

5. Trauma



Explanation

a. Indication for primary CT evaluation of the temporal bone include conductive hearing loss, deformed auricle, external auditory canal abnormalities, chronic otitis media/cholesteatoma, postoperative conditions, trauma and peripheral facial nerve paralysis if there is evidence for a cholesteatoma or a middle ear mass. Chronic otitis media/cholesteatoma and postoperative conditions additionally require contrast enhanced images.

b. Indication for primary CT evaluation of the temporal bone include conductive hearing loss, deformed auricle, external auditory canal abnormalities, chronic otitis media/cholesteatoma, postoperative conditions, trauma and peripheral facial nerve paralysis if there is evidence for a cholesteatoma or a middle ear mass. Chronic otitis media/cholesteatoma and postoperative conditions additionally require contrast enhanced images.

c. Indication for primary CT evaluation of the temporal bone include conductive hearing loss, deformed auricle, external auditory canal abnormalities, chronic otitis media/cholesteatoma, postoperative conditions, trauma and peripheral facial nerve paralysis if there is evidence for a cholesteatoma or a middle ear mass. Chronic otitis media/cholesteatoma and postoperative conditions additionally require contrast enhanced images.

d. Indication for primary CT evaluation of the temporal bone include conductive hearing loss, deformed auricle, external auditory canal abnormalities, chronic otitis media/cholesteatoma, postoperative conditions, trauma and peripheral facial nerve paralysis if there is evidence for a cholesteatoma or a middle ear mass. Chronic otitis media/cholesteatoma and postoperative conditions additionally require contrast enhanced images.

Abstract
We present a case of complex hemifacial microsomia (HFM) which was diagnosed at the age of 46 years. Imaging findings of a complex deformity of the temporal bone are presented and connected to a broad range of clinical symptoms. Computed tomography (CT) imaging indications are discussed briefly.
