Seventeen years of research into the structural complexities of the human ear culminated in the 1704 publication of De aure humana tractatus. This seminal text by Antonio Maria Valsalva provided the foundational descriptions for the auditory tubes and established diagnostic maneuvers still utilized in modern circulatory and ear pressure testing across medical and aerospace fields.
Academic Foundation and Training
Born in 1666 in Imola, which was then part of the Papal States, Valsalva initially received an education in humanities, mathematics, and natural sciences at a Jesuit institution. He transitioned to the University of Bologna to pursue medicine and philosophy. During this period, he studied under Marcello Malpighi, a pioneer in microscopic anatomy. Valsalva successfully completed his medical degree in 1687.

In 1695, Valsalva accepted the position of surgeon at the Hospital of the Incurables, known as Sant'Orsola, in Bologna. His institutional influence expanded in 1705 when he was named professor of anatomy at the University of Bologna. Beyond his faculty duties, he served as the president of the Clementine Institute of Arts and Sciences. In 1709, he married Elena Lisi. He died in 1723 following a stroke in Bologna and was interred at the church of San Giovanni in Monte.
Anatomical Observations and Medical Doctrines
Valsalva's anatomical research led to the identification of various structures, including the aortic sinuses, the Valsalva antrum, and specific muscle groups. He observed that brain lesions often manifest as contralateral weakness, a finding designated as the Valsalva doctrine. His investigative methods were rigorous; he conducted numerous autopsies, at times tasting cadaveric fluids to document their properties. He also advocated for the humanitarian treatment of psychiatric patients and actively opposed the use of cauterization for wound care.
Legacy and Scientific Transmission
Much of Valsalva’s work reached the wider medical community posthumously. His student, Giovanni Battista Morgagni, edited his complete writings and authored a biography, both released in 1740. The Valsalva family donated a collection of dried anatomical specimens to the Institute of Sciences in 1711, which influenced the Bolognese school of wax modeling. These models, including representations of the heart and lungs, remain housed at the Museum of Anatomy.

Questions readers ask
What is the Valsalva maneuver?
It is a physiological test of circulatory function and ear pressure equalization that Valsalva described in his 1704 treatise.
How is his work utilized in modern space exploration?
The Valsalva device, integrated into spacesuits, allows astronauts to equalize ear pressure manually without using their hands to block the nose.
