Ethmoidal scleroma: endoscopic diagnosis and treatment.

Twenty patients with medically treated rhinoscleroma and residual ethmoidal manifestations were examined using CT scanning. Cases with positive radiological data of the ethmoids underwent diagnostic and therapeutic nasal endoscopy. It has been found that ethmoidal scleroma is not as rare a condition as was previously thought. The diagnostic and therapeutic value of nasal endoscopy in ethmoidal scleroma is discussed.
