[Nasal osteocartilaginous necrosis caused by cocaine. Our experience with two patients].

Sinonasal osteocartilaginous necrosis induced by the abuse of inhaled cocaine must be considered in the differential diagnosis of those pathologies that produce facial midline destructions. We report two cases corresponding to women admitted in our Hospital because of such entity. There were analysed their respective clinical histories, exploration data, complementary tests, medical-surgical treatment and evolution. Cocaine is one of the drugs that has increased in last 10 years producing an elevated number of complications, as we could proved on the bibliographic review performed.
