Way to Maassa-Keniga

The Maass-Koenig method is a surgical operation to remove liver ulcers. Named after the German surgeons Karl Maass and Franz Koenig, who first used this method in the 19th century.

The essence of the operation is as follows: under general anesthesia, an incision is made in the right hypochondrium. Then the surgeon opens the abdominal cavity and examines the liver, localizing the abscess. Next, an incision is made in the liver directly above the abscess. The pus is aspirated, the abscess cavity is thoroughly washed with antiseptics. The walls of the cavity are cauterized with antiseptic solutions, then the wound is sutured.

Thus, the Maass-König method makes it possible to effectively treat ulcerative liver lesions using surgical intervention. This method remains relevant today.

Maass-König method

The Maass-König method is a surgical method for treating bone cysts, proposed in 1885 by the German surgeon Karl Mauss and the German gynecologist Karl König.

Karl Maass (1841-1922) graduated from the Faculty of Medicine at the University of Berlin in 1869, where he studied surgery. After graduating from university, he worked as an assistant in a surgical clinic in Berlin. In 1879 he was appointed professor of surgery at the University of Vienna, and in 1901 at the Medical Academy of Vienna. From 1892 to 1911 he was director of the surgical clinic of the University of Vienna.

In 1877, Maass described a cyst that developed from the body of the sphenoid bone. Later, such cysts began to be called Maass cysts. Maass proposed to treat them by removing the cyst along with the part of the body of the sphenoid bone on which it developed. The method was named after him.

The Maass-Koenig method was one of the first methods of treating bone cysts and is now rarely used.
