Ciliated nasal epithelium of transplanted patients without and with rhinosinusitis under transmission electron microscopy. (A) Ciliated cells with a cilia decrease and microvilli increase. (B) Ciliated cells without cilia or mitochondria and with cytoplasmic vacuolization. (C) Normal ciliated epithelium with goblet cells. (D) Ciliated epithelium without cilia and mononuclear cells migrating to the surface (arrows). (E) Epithelium with normal cilia. (F) Compound cilia (longitudinal). (G) Compound cilia (*transversal). (H) Squamous metaplasia. Right column, patients without rhinosinusitis; left column, patients with rhinosinusitis.
