Otorhinolaryngology as "Made in Germany" since 1921: an international perspective.

In 2021, the German Society of Otorhinolaryngology, Head Neck Surgery celebrates the 100th anniversary of its foundation. The aim of this research is to present the main advances and innovations developed in Germany since 1921-as selected and studied from outside Germany, first in other languages and then in German, hence an international "Made in Germany"-that either directly or indirectly expanded or impacted the development of Otorhinolaryngology (ORL). This gives an unusual but extremely interesting perspective on the history of ORL in Germany. However, events that are too recent to have already entered into the history of ORL are not discussed, not least due to the often huge difficulties in actually identifying the main protagonists. In all, 11 landmarks regarded to be "Made in Germany" and which have had a major impact on the development of ORL since 1921 are presented. Some of these are well known, some not, but their importance must not be underestimated. They are presented here in chronological and specific sections: 1. Indisputable glasses to observe nystagmus; 2. Most monumental ORL encyclopedia ever published; 3. Histology of the inner ear is efficient; 4. Introduction of antibiotics to treat ORL infections; 5. Color atlas of ORL pathologies as support for teaching; 6. Tympanoplasty concept revolutionizes surgery of the ear; 7. Zeiss operating ear microscope broadens the surgical field; 8. Microlaryngoscopy suspension technique defines a new era in laryngeal surgery; 9. Septum resection becomes septum correction; 10. Karl Storz nasal endoscope opens up new surgical techniques; 11. The history of ORL must belong to ORL. This research demonstrates that Germany played a major role in and has had a profound impact on advances in ORL since 1921, a real otorhinolaryngological "Made in Germany."
