We report a single-stage approach employing piezoelectric instrument (PEI) to optimize cavity osteoplasty, atraumatic cochlear access, and electrode stabilization in the setting of partial scala tympani ossification. A 72-year-old female with left profound sensorineural hearing loss and prior canal wall (CW)-down mastoidectomy underwent CI with posterior CW reconstruction. Angled and straight PEI inserts facilitated controlled bone removal over the facial nerve and creation of a bony slit with overhang to secure the electrode lead. Ossified segments of the scala tympani were carefully cleared, enabling full insertion of a perimodiolar electrode array, subsequently reinforced with double-layer cartilage. At 8-month follow-up, no clinical or electrophysiological evidence of electrode migration was observed. PEI is a promising tool for safe, atraumatic osteoplasty and stable electrode positioning in complex radical cavities.<\/jats:p>","DOI":"10.1093\/jscr\/rjag653","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T11:51:44Z","timestamp":1786189904000},"source":"Crossref","is-referenced-by-count":0,"title":["Piezoelectric shaping of radical mastoid cavity and dissection of ossified cochlea prior to cochlear implantation"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8950-0524","authenticated-orcid":false,"given":"Samiah S","family":"Al-Angari","sequence":"first","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, Helios Klinikum Berlin-Buch , Schwanebecker Chaussee 50, Berlin, 13125 ,","place":["Germany"]},{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, College of Medicine, King Saud University , King Abdulaziz Road, AlMalaz, Riyadh, 11545 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Bloching","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, Helios Klinikum Berlin-Buch , Schwanebecker Chaussee 50, Berlin, 13125 ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharina","family":"St\u00f6lzel","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, Helios Klinikum Berlin-Buch , Schwanebecker Chaussee 50, Berlin, 13125 ,","place":["Germany"]},{"name":"Medical School Berlin, Hochschule f\u00fcr Gesundheit und Medizin , R\u00fcdesheimer Stra\u00dfe 50, 14197, Berlin ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6399-2081","authenticated-orcid":false,"given":"Stefan","family":"Lyutenski","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, Helios Klinikum Berlin-Buch , Schwanebecker Chaussee 50, Berlin, 13125 ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"2026081420471897400_ref1","doi-asserted-by":"publisher","first-page":"171","DOI":"10.1007\/s00405-008-0828-0","article-title":"Cochlear implantation in patients with acute or chronic middle ear infectious disease: a review of the literature","volume":"266","author":"Hellinngmann","year":"2009","journal-title":"Eur Arch Otorhinolaryngol"},{"key":"2026081420471897400_ref2","doi-asserted-by":"publisher","first-page":"555","DOI":"10.1177\/0194599816651239","article-title":"Systematic review and meta-analysis of surgical complications following cochlear implantation in canal wall down mastoid cavities","volume":"155","author":"Hunter","year":"2016","journal-title":"Otolaryngol Head Neck Surg"},{"key":"2026081420471897400_ref3","first-page":"1","volume-title":"Sprachaudiometrie -Grundlagen und praktische Anwendung einer Sprachaudiometrie f\u00fcr das deutsche Sprachgebiet","author":"Hahlbrock","year":"1957"},{"key":"2026081420471897400_ref4","doi-asserted-by":"publisher","first-page":"937","DOI":"10.1288\/00005537-196108000-00004","article-title":"Variations in the temporal bone course of the facial nerve","volume":"71","author":"Fowler","year":"1961","journal-title":"Laryngoscope"},{"key":"2026081420471897400_ref5","doi-asserted-by":"publisher","first-page":"10","DOI":"10.1007\/s00106-022-01211-8","article-title":"Piezoelectric ear surgery: a systematic review","volume":"71","author":"Lyutenski","year":"2023","journal-title":"HNO"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/8\/rjag653\/70653825\/rjag653.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/8\/rjag653\/70653825\/rjag653.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,15]],"date-time":"2026-08-15T00:47:37Z","timestamp":1786754857000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjag653\/8761910"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8]]},"references-count":5,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,8,4]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjag653","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,8]]},"published":{"date-parts":[[2026,8]]},"article-number":"rjag653"}}
