In the structure of morbidity and mortality has significantly increased the role of mycoses. The increase in their spread is due not only to the improvement of the quality of diagnosis, but also the emergence of new strains resistant to previously used antifungal drugs, a significant change in the immune status of the population.

Paraganglioma of the maxillary sinus

Auris Nasus Larynx, 2013
Primary paragangliomas of the paranasal sinuses are very rare conditions with only few cases described in the literature. Paragangliomas are locally aggressive, often recur and can metastasize. Usually, open surgery is used to resect such tumors from the sinonasal tract. Here, a case of a large paraganglioma of the left maxillary sinus and nasal cavity,

A case report is presented involving the endodontic retreatment of a maxillary second molar associated with a sinus radiopacity. Disappearance of sinus pathosis occurred within 6 days after root canal debridement. A direct relationship between apical pathosis and a pseudocyst of the maxillary sinus is suggested.
