ABSTRACT
A 5-year-old deaf-mute girl was shown on petrous bone tomography to have bilateral enlarged vestibules with assimilation of the lateral semicircular cannals, bilateral absence of the cochlea, aplasia of the left internal auditory canal with only the facial nerve compartment being present, and hypoplasia of the right internal auditory canal. The embryological basis of these inner ear abnormalities is discussed.

Three cases of keratosis obturans, which were studied by tomography of the petrous temporal bone, are described. The widening of the deep bony part of the external auditory canal by pressure erosion of an impacted benign slowly-growing mass is the key radiological finding. Erosion was so severe as to involve the facial nerve canal in one and the temporo-madibular joint in two cases. The theories of causation are reviewed. Tomography using elliptical tube movement was valuable in diagnosis, pre- and post-operative management.

Three unusual cases of mastoid abscess are described. Case histories and the clinical, laboratory, radiological, surgical, and histopathological findings in the patients are reported. Operculated eggs measuring about 60 mu times 40 mu were seen in pus obtained from two cases, but no adult worm was recovered. The findings suggest that the infections could have been caused by either Paragonimus species or Poikilorchis (Achillurbania) species.
