CLASSIFICATION OF CONGENITAL MIDDLE AND EXTERNAL EAR MALFORMATIONS: CT STUDY
Oncology
Oncology
Original Research
Original Research
The authors used high-resolution computed tomography (HRCT) for
studying 52 congenitally malformed ears in 45 children between five and 10
years of age. In six children the malformations were bilateral. The malformations
clinically manifested as microtia, atresia of the external auditory canal
and conductive deafness.
Analyzing anatomical details and pathological changes on HRCT axial
sections the authors established three groups of malformations. In the first
group, auditory assicles were malformed in almost all cases, in the second
group besides deformed auditory ossicles in majority of cases, the mastoid
was apneumatised, and in the third group there were malformed auditory
ossicles and the mastoids were apneumatised and in more than half of cases
cavum tympani was malformed or filled with mesenchyme.
These features have great importance in surgical reconstruction of
congenital middle ear malformations.
