HRCT TEMPORL BONE FINDINGS IN CSOM

Pragya S khare, Ashutosh Chitnis, Priti S Kapoor

Abstract


Background and purpose : To study the HRCT temporal bone findings in chronic middle ear and mastoid infections with
reference to its extent and complications.
Materials and Methods : After an initial clinical assessment, 30 patients diagnosed clinically with chronic suppurative otitis
media (CSOM) and mastoiditis were refered for a HRCT of temporal bone which was done with a Toshiba Activion16 slice MDCT.
Results : Of the 30 patients, age at presentation ranged from 5 to 40 years.The mean age was 25 years. Otorrhoea was the most
common symptom. Chronic mastoiditis was the most common complication followed by erosion of ossicles. Incus is most
commonly eroded among the ossicles.Bezold's abscess was seen in only one case.
Conclusions : HRCT of temporal bone is useful in identifying various findings related to the location and extent of disease which
are clinically occult and is of great importance in guiding the surgeon in planning the surgical approach.
