Prenatal and postnatal development of the tympanic portion of the temporal bone

Age of closure of the foramen of Huschke: an osteological study

“…Krmpotić-Nemanić et al (1999) reported that 25% of individuals had reached this stage of development by 1 year and the remaining 75% of cases achieved this state between 1 and 2 years. Weaver (1979) found that the youngest individuals from the Grasshopper Pueblo skeletal series to reach this stage of development were aged approximately 1 year.…”

“…Accounts of a persistent foramen in the adult are reported from a worldwide selection of recent and ancient human populations, and incidence varies from 0-67%, although part of this variation may reflect methodological differences in classification of the foramen and in reporting bilateral traits (Wood-Jones, 1931a,b,c, 1933Krogman, 1932;Wunderley & Wood-Jones, 1933;Laughlin & Jørgensen, 1956;Anderson, 1960;Berry & Berry, 1967;Dodo, 1974;Dodo & Ishida, 1987;Hauser & De Stefano, 1989;Wang et al, 1991;Herzog & Fiese, 1989;Krmpotić-Nemanić et al, 1999;Hanihara & Ishida, 2001).…”

“…A number of authors have described the development of the tympanic plate in detail (Anson et al, 1955;Anderson, 1960;Ars, 1989;Krmpotić-Nemanić et al, 1999), but none of these documents age-related changes in a systematic way. Despite this, the age of closure of the foramen is typically cited to take place by the fifth year of life (Hauser & De Stefano, 1989;Wang et al, 1991).…”

Evaluation of Influences of the Viennese Anatomical School on the work of the Croatian Anatomist Jelena Krmpotic-Nemanic

“…In her next paper entitled 'Prenatal and postnatal development of the tympanic portion of the temporal bone' she again used Jena's textbooks: Hertwig's Lehrbuch der Entwicklungsgeschichte des Menschen und der Wirbeltiere and Peter's Handbuch der Anatomie des Kindes, published in 1915 and 1934 respectively, as references for comparison [19]. 'Th e Fate of the Arachnoid Villi in Humans' brings the results of Professor's investigations performed on the 50 disarticulated macerated skull bones from the newborns to 30 year olds and on the 20 skulls from individuals of 30 to 80 years of age, based on which she concluded that the structural changes of villi arachnoidales could produce thrombophlebitis and hydrocephalus externus, especially in children and thus are of the great importance for neurologists, neurosurgeons and otorhinolaryngologist [20] .…”

“…In contrast to the Basel nomenclature formulated in 1895, which was dependant on the position of human body and was naming anatomical structures after their discoverers; the Jena one was independent of the position of human body and was not naming anatomical structures after their founders, and was thus more advanced. Although the current Paris anatomical nomenclature was formed in 1955 as a compromise between the two earlier ones in being dependant on the human body position, but not naming the body structures after their founders, as showed in the above analyzed examples, the Jena nomenclature still remained continuously present as a reference for comparison in the anatomical work of Professor Krmpotic-Nemanic [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”
