Antibiotics are given for an infection. Chronic atelectasis is often treated with antibiotics because infection is almost inevitable. In certain cases, the affected part of the lung may be surgically removed when recurring or chronic infections become disabling or bleeding is significant. If a tumor is blocking the airway, relieving the obstruction by surgery, radiation therapy, chemotherapy, or laser therapy may prevent atelectasis from progressing and recurrent obstructive pneumonia from developing.

Diagnosis
A positive culture in MacConkey agar is diagnostic, but cultures are only positive in 50–60% of cases. Diagnostic characteristics are most commonly found in the granulomatous stage and are described as being plasma cells with birefringent inclusions, Russell bodies, pseudoepitheliomatous hyperplasia, and groups of large vacuolated histiocytes containing Klebsiella rhinoscleromatis (Mikulicz cells). Treatment
It is not lethal in nature and is responsive to tetracycline or ciprofloxacin. Surgical treatment include rhinoplasty. However, if left untreated the disease can lead to sepsis, bleeding, or other chronic conditions that can be fatal. History
Hans von Hebra (1847–1902) wrote the classical description of the disease in a paper published in the January 1870 issue of the Wiener Medizinische Wochenschrift. Hans von Hebra was the son of Czech born dermatologist Ferdinand Ritter von Hebra (1816–1880), founder of the New Vienna School of Dermatology. He was assisted by M. Kohn who provided much of the histology for the paper. M. Kohn is the birth name of Moritz Kaposi (1837–1902). In 1876, Mikulicz contributed to the microscopic histology. In 1882, Anton Von Frisch (1849–1917) discovered the gram-negative bacillus which causes the disease. Terminology
