Primary ciliary dyskinesia results in characteristic clinical symptoms, including chronic pansinusitis, recurrent infections of the respiratory tract, and infertility. Kartagener's syndrome is clinically distinguishable by the presence of situs
inversus from this group of diseases. Other otolaryngological manifestations of primary ciliary dyskinesia which have been reported include otitis media with effusion, tympanosclerosis, keratosis obturans, and chronic cholesteatoma.
Congenital nystagmus is another otological symptom characterized by
ocular oscillation, which usually appears in the early infancy, and is often
associated with visuosensory abnormalities.
Recently, we experienced a 13 year-old boy with congenital nystagmus in
addition to all other manifestations of Kartagener's syndrome. Although
the clinical implication is not clear, it is possible that two diseases share
the same developmental abnormality.
