The path length of the ET lumen of the 3-month-old infant was 21.2 mm, and its growth was in correlation with age to attain its adult length (average, 37.00 \u00b1 4.16 mm). The ratio of the length of the cartilaginous portion together with the junctional portion to the length of the bony portion was 8:1 in an infant at the age of 3 months and 4:1 in adults. That the bony portion of the ET develops relatively more than the cartilaginous and junctional portions may cause this finding. In addition, there is a developmental shift in the orientation of the cartilaginous portion with respect to the bony portion of the ET. In children, the cartilaginous and bony portions are both aligned with the line that connects the pharyngeal orifice and the tympanic orifice. In adults, however, the cartilaginous portion is angled inferiorly and laterally from the bony portion. This change may reflect the relative growth of the face.<\/jats:p>","DOI":"10.1177\/000348940010900603","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"542-548","source":"Crossref","is-referenced-by-count":46,"title":["Length of the Eustachian Tube and its Postnatal Development: Computer-Aided Three-Dimensional Reconstruction and Measurement Study"],"prefix":"10.1177","volume":"109","author":[{"given":"Ken","family":"Ishijima","sequence":"first","affiliation":[{"name":"Hamamatsu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isamu","family":"Sando","sequence":"additional","affiliation":[{"name":"Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiaki","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Fukushima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carey","family":"Balaban","sequence":"additional","affiliation":[{"name":"Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Takasaki","sequence":"additional","affiliation":[{"name":"Nagasaki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2000,6]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"388","volume-title":"Pediatric otolaryngology","author":"Bluestone CD","year":"1996","unstructured":"Bluestone CD, Klein JO.
