Conventional and tomographic examinations of the ear and eye were done on three of five patients with craniotubular bone dysplasia. Each of these three had symptoms of hearing loss and diminished visual acuity. Abnormal tomographic findings in each case included constriction of optic foramina, auditory canals, and middle ear cavities; malformations of ossicles; and thickening of otic capsules. Two of these three patients with craniotubular bone dysplasia had craniometaphyseal dysplasia (Pyle disease) and one had a variety, or variant, of craniometaphyseal dysplasia.
A tomographic examination is necessary for recognition and detection of these abnormalities and as a guide for clinicians before surgery of the ear or eye is done.
