Careful preservation of the posterior canal wall skin in this procedure obviates the need for obliteration of the middle-ear mucosa and closure of the external auditory canal.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215108004039_sec2\"><jats:title>Objectives:<\/jats:title><jats:p>To present a canal wall down technique for cochlear implantation, which preserves the intact posterior external auditory canal wall skin. This approach is employed when a standard facial recess cochleostomy is not possible.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215108004039_sec3\"><jats:title>Methods:<\/jats:title><jats:p>Three cases of intact posterior meatal skin, canal wall down cochlear implantation are presented together with long-term follow-up results. In all three cases, implantation via a facial recess approach was not possible. One patient suffered from severe cochlear otosclerosis with obliteration of the round window niche. The second patient had severe middle-ear fibrosis with encasement of all middle-ear structures and obliteration of routine landmarks. The third patient had an anterior sigmoid sinus obscuring access to the facial recess. Cochlear implantation via the canal wall down, intact posterior canal wall skin technique was successfully performed in each of these patients.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215108004039_sec4\"><jats:title>Results:<\/jats:title><jats:p>All three patients were successfully implanted, with full electrode insertion achieved. All patients subsequently became active implant users. One patient did suffer from a minor wound complication post-operatively, unrelated to the approach. Patient follow up ranged from four to six years.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215108004039","type":"journal-article","created":{"date-parts":[[2008,10,31]],"date-time":"2008-10-31T14:01:41Z","timestamp":1225461701000},"page":"903-906","source":"Crossref","is-referenced-by-count":14,"title":["Intact meatal skin, canal wall down approach for difficult cochlear implantation"],"prefix":"10.1017","volume":"123","author":[{"given":"M J","family":"Carfrae","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Foyt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2017,3,8]]},"reference":[{"key":"S0022215108004039_ref20","doi-asserted-by":"publisher","DOI":"10.1177\/019459988609400317"},{"key":"S0022215108004039_ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(96)70275-9"},{"key":"S0022215108004039_ref24","doi-asserted-by":"publisher","DOI":"10.1016\/S0385-8146(12)80023-X"},{"key":"S0022215108004039_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(99)70244-5"},{"key":"S0022215108004039_ref18","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2000.107406"},{"key":"S0022215108004039_ref14","doi-asserted-by":"publisher","DOI":"10.1159\/000067577"},{"key":"S0022215108004039_ref13","doi-asserted-by":"publisher","DOI":"10.1159\/000067578"},{"key":"S0022215108004039_ref3","doi-asserted-by":"publisher","DOI":"10.1177\/019459988809800113"},{"key":"S0022215108004039_ref25","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100139842"},{"key":"S0022215108004039_ref5","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199511000-00008"},{"key":"S0022215108004039_ref9","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlg.0000157833.31003.b5"},{"key":"S0022215108004039_ref17","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1080\/00016489950181693","article-title":"New window for cochlear implant insertion","volume":"119","author":"Colletti","year":"1999","journal-title":"Acta Otolaryngol (Stockh)"},{"key":"S0022215108004039_ref11","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200201000-00010"},{"key":"S0022215108004039_ref15","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200401000-00008"},{"key":"S0022215108004039_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0709(00)80108-8"},{"key":"S0022215108004039_ref19","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100090332"},{"key":"S0022215108004039_ref10","first-page":"201","volume-title":"Tympanoplasty, Mastoidectomy, and Stapes Surgery","author":"Fisch","year":"1994"},{"key":"S0022215108004039_ref22","first-page":"31","article-title":"Soft-wall reconstruction of posterior canal wall for surgery of noninflamed ears","volume":"20","author":"Takahashi","year":"1999","journal-title":"Am J Otol"},{"key":"S0022215108004039_ref16","doi-asserted-by":"publisher","DOI":"10.1258\/0022215011907451"},{"key":"S0022215108004039_ref8","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199708000-00005"},{"key":"S0022215108004039_ref6","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1995.01890080005001"},{"key":"S0022215108004039_ref12","first-page":"27","article-title":"Veria operation: cochlear implantation without a mastoidectomy and a posterior tympanotomy.
