[The immotile cilia syndrome. A case report].

A case of congenital bronchiectasis associated with hypoplasia [correction of hyperplasia] of maxillary sinuses and sinusitis in a 3-year-old boy is presented. The ultramicroscopic examination of nasal mucosa showed abnormalities in the ultrastructure of the mucociliary system (spare cilia, absence of basal corpuscles, cytoplasmatic projections) clearly suggesting the ciliary immotility syndrome.
