title: [Changes in the mucous membrane of the patients with chronic maxillary sinusitis caused by foreign bodies].
abstract: The objective of the present work was to study the morphofunctional changes in maxillary sinus mucosa of the patients with odontogenic maxillary sinusitis (OMS) associated with the presence of a foreign body depending on its duration. A total of 105 hospitalized patients were examined and operated. Biopsy samples taken from mucosa and contents of the maxillary sinuses during surgery were investigated. The histological study included the standard sample processing followed by paraffin embedding of the material and staining of the micropreparations with hematoxylin and eosin. It was shown that foreign bodies present in the maxillary sinuses cause marked structural reorganization of the mucous membrane usually with the predominance of hypertrophic and polypous changes.
