However, preoperative imaging often shows only small areas where the FMT (4.5\u00a0mm) or screws (4.0\u00a0mm) can be fully and safely inserted without the need to use lifts. Navigation systems allow precise placement of the device and prevent potential complications such as dural or vascular injuries. The latest version of the preoperative planning software Otoplan\u00ae allows to assess bone thickness and perform virtual implantation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials &amp; methods<\/jats:title>\n                    <jats:p>Six children between 3 and 12\u00a0years of age underwent BB implantation using Otoplan\u00ae with export of the planned BB position to a navigation system. Prior to an intraoperative cone beam CT (CBCT), 3 marker screws were placed in the temporal bone. Images were loaded into Otoplan\u00ae to virtually define the optimal BB position and export the corresponding model. CBCT scan and model were then loaded into an electromagnetic navigation system. The screws were used to accurately register the system, and the planned BB placement was projected onto the patient. BB implantation was performed accordingly and finally the marker screws were removed. Possible complications were monitored and the audiological success was measured using an age-appropriate speech test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Bone thickness at the screw location was over 4.0\u00a0mm in every case, documenting the accuracy of the procedure. No medical complications occurred intraoperatively, during the immediate hospital stay, or up to and including the initial fitting 4\u20136\u00a0weeks after implantation. Speech test results were greater than or equal to 90% in all measurable patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Virtual implantation with Otoplan\u00ae can be loaded into a navigation system to mark the safe position of the screws on the temporal bone. Projecting the planned position onto the patient using navigation is a practical tool that can make implantation more reliable and safer for patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00405-025-09786-y","type":"journal-article","created":{"date-parts":[[2025,11,4]],"date-time":"2025-11-04T21:00:22Z","timestamp":1762290022000},"page":"1539-1546","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Precise bonebridge implantation in challenging cases: a novel approach using virtual planning and electromagnetic navigation"],"prefix":"10.1007","volume":"283","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3721-5585","authenticated-orcid":false,"given":"Nils Kristian","family":"Prenzler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Busch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niels","family":"Rudnik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Lenarz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Schurzig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,11,4]]},"reference":[{"key":"9786_CR1","doi-asserted-by":"publisher","DOI":"10.21053\/ceo.2021.02208","author":"SH Bae","year":"2022","unstructured":"Bae SH et al (2022) Clinical experience of using active transcutaneous bone conduction implants (Bonebridge) in children under 5 years old.
