The prosthesis was designed to fit between the medial side of the incus and stapes footplate and had a mean length of 3.6 \u00b1 0.5 mm. The mean pre\u2010 and postoperative ABG were 38.3 \u00b1 4.8 and 13.3 \u00b1 10.0 dB, respectively. The postoperative ABG at frequencies of 0.25, 0.5, 1.0, 2.0, 3.0, and 4.0 kHz were 20.0 \u00b1 15.4, 16.9 \u00b1 11.9, 16.3 \u00b1 10.3, 10.6 \u00b1 7.3, 12.9 \u00b1 14.0, and 23.1 \u00b1 16.2 dB, respectively. The mean ABG closure was 9.5 dB (range, \u22121.3\u223c35.8 dB). Seven cases obtained the best results (mean ABG closure \u226410 dB). In the remaining patient, the mean ABG closure was 9.5 dB until 6 months after surgery, but was 35.8 dB 1 year after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>IFA seems to be a reasonable surgical option in patients with missing the stapes superstructure, but with a mobile footplate in which the long process of incus is preserved.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>4 <jats:italic>Laryngoscope<\/jats:italic>, 126:2569\u20132573, 2016<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.25908","type":"journal-article","created":{"date-parts":[[2016,2,11]],"date-time":"2016-02-11T04:58:52Z","timestamp":1455166732000},"page":"2569-2573","source":"Crossref","is-referenced-by-count":1,"title":["Incus footplate assembly: Indication and surgical outcome"],"prefix":"10.1002","volume":"126","author":[{"given":"Mina","family":"Park","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery and Healthcare Research Institute Seoul National University Hospital, Healthcare System Gangnam Center Seoul Korea"},{"name":"Department of Translational Biomedical Research Seoul National University College of Medicine Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sungjun","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery Seoul National University College of Medicine, Seoul National University Bundang Hospital Seongnam Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byung Yoon","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery Seoul National University College of Medicine, Seoul National University Bundang Hospital Seongnam Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sun O","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery Sungkyunkwan University School of Medicine Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chong Sun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery Seoul National University College of Medicine, Seoul National University Bundang Hospital Seongnam Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ja\u2010Won","family":"Koo","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery Seoul National University College of Medicine, Seoul National University Bundang Hospital Seongnam Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,2,10]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"155","article-title":"Middle ear exploration results in suspected otosclerosis cases: are ossicular and footplate area anomalies rare?","volume":"25","author":"Nemati S","year":"2013","journal-title":"Iran J Otorhinolaryngol"},{"key":"e_1_2_6_3_1","unstructured":"NgM.Exploratory tympanotomy.
