April 5, 2025 is the 100th anniversary of the birth of the Honored Scientist of the Republic of Tatarstan, Doctor of Medical Sciences, Professor Lyudmila Georgievna Svatko (05.04.1925-24.12.2009). Lyudmila Georgievna was born in Kazan in the family of a doctor. In 1948 she graduated with a red diploma from Kazan State Medical Institute (KSMI) and chose otorhinolaryngology as her specialty. After completing her residency at the Department of Ear, Throat and Nose Diseases, starting from 1951 Ludmila Georgievna worked as an attending physician at the Clinic of Ear, Throat and Nose Diseases of the KSMI. Active scientific research in the field of otorhinolaryngology and oncology culminated in 1954 with the defense of a PhD thesis on the topic: “Changes in the innervation apparatus of human laryngeal muscles in cancer and some features of afferent innervation of these muscles”, performed under the guidance of Prof. A.N. Mislavsky and Prof. N.N. Lozanov. In 1958 Ludmila Georgievna became an assistant of the Department of ENT Diseases of the KSMI. From L.G. Svatko’s memoirs: “After 10 years I took up unique hearing-improving surgeries. At that time they were performed only in Moscow, Leningrad and Kiev. In Kazan I was the first. However, before that I had operated on about 100 corpses...”. Thanks to the efforts of L.G. Svatko, Associate Professor of the Department of Otorhinolaryngology, at the Department of Kazan Medical Institute on the basis of the Republican Clinical Hospital, a hearing center was established in 1965, and soon an independent department of hearing surgery for 40 beds was opened. From 1965 to 1974, L.G. Svatko performed 545 operations on the stapes by various modified methods - from sparing to radical (stapedectomies).
