Anton Maria Valsalva (1666-1723), "of Bologna, who was one of Malpighi's students at Padua and the teacher of Morgagni, wrote the first full account of the minute anatomy of the ear in his 'De Aure Humana Tractatus' ((Bolgna 1704) Treatise on the Human Ear), in which the whole structure of the ear is described and illustrated with many new discoveries, and the uses of all its parts are investigated; in which is inserted a new description and delineation of the uvula and pharynx. He was the first to define the ear's three regions-outer, middle, and inner-and to explain their relative functions. The 'Treatise' is arranged in six chapters. The first three are anatomic and deal with the parts of the ear; the last three are physiologic and explain the functions of these parts. The auricle and auditory meatus, the tympanum and middle ear, and the labyrinth and inner ear are discussed. Chapter 2 includes Valsalva's report, promised on the title page, of the musculature of the uvula and pharynx; these are depicted on separate plates. The ten illustrations are good line engravings, of which the most striking are those of the nerves and blood vessels of the outer ear, the carotid artery, the semi circular canals, and the structure of the whole ear. Valsalva described and named the eustachian tube, which connects the middle ear and the pharynx. His consideration of the eustachian tubes led to the "respiratory maneuver" named for him; if the tubes are patent and if the nose and mouth are closed, a forcible expiratory effort increases pressure on the tympanic membranes. Valsalva used this procedure to expel pus and foreign bodies from the middle ear. Since his time, the Valsalva maneuver has proved to be of value to the internist, the otologist, and the radiologist. In the section on the pharyngeal muscles, he detailed the dysphagia which has also been named for him. By the digital manipulation of "a kind of dislocation of the cartilaginous appendages of the hyoid bone," he relieved a woman who could not eat after a lump of beef had lodged in her throat." William R. Lefanu, Notable Medical Books from the Lilly Library (1976), p.101 Politzer, Hist. of otology, pp. 136-143: 'The scientific value of this work is demonstrated by the fact that the anatomical sections of all the otological treatises up to the 19th century are based on Valsalva's work, part of which remain valid even today. Morgagni's edition, Venice, 1740, also contains his anatomical letters. Valsalva mentions for the first time the small sebaceous glands . in the skin of the auricle and compares them to analogous structures in other parts of the body, e.g. the nose. Valsalva's description of the Eustachian tube is classic, again demonstrating his masterful dissection technique. Valsalva was the first to observe the presence of a watery fluid in the labyrinth. Valsalva was the first to describe a muscular dilatator tubae that widens the Eustachian tube during the perception of sound. Valsalva was the first physician who inspected the tympanic membrane in living subjects.' It was Valsalva who first rationalized treatment in otology. This is also the first printing of .
