Biological compatibility of a tissue engineered construct of the trachea (synthetic scaffold) and allogenic mesenchymal stem cells was studied on laboratory Papio hamadryas primates. Subcutaneous implantation and orthotopic transplantations of tissue engineered constructs were carried out. Histological studies of the construct showed chaotically located filaments and mononuclear cells fixed to them. Development of a fine connective tissue capsule was found at the site of subcutaneous implantation of the tissue engineered construct. The intact structure of the scaffold populated by various cell types in orthotopic specimens was confirmed by expression of specific proteins. The results indicated biological compatibility of the tissue engineered construct with the mesenchymal stem cells; no tissue rejection reactions were recorded; simulation of respiratory disease therapy on Papio hamadryas proved to be an adequate model.

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw. Involvement of the maxillary sinus is an unusual presentation. We present the case of a 23-year-old man with extensive KCOT and impacted third molar in the right maxillary sinus. The clinical, radiological, and histological features of this tumor and its surgical management are discussed.

The pathogenesis of granulation tissue that arises periodically around artificial Eustachian tubes was elucidated by histologic examination of 15 cases of tube granuloma. All cases showed the presence of a keratin foreign-body granuloma. The implanted squames incited a foreign-body type of granulomatous reaction and produced a friable vascular exuberant mass that surrounded the artificial Eustachian tube. Histologically, the tube granuloma was characterized by the presence of irregular ovoid slit-like spaces that contained keratin squames, and it was surrounded by foreign-body giant cells.
