To investigate the bilateral symmetry, preoperative tri\u2010dimensional (<jats:styled-content style=\"fixed-case\">3D<\/jats:styled-content>) computed tomography (<jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content>) image reconstruction was used to compare the distances between the mandibular condyle and implant placement estimation (mandible\u2010implant distance) in both the right and left ears of the subjects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The guide\u2010marker could be used to estimate the bilateral implant placement in all subjects included in this study, simply and easily, including one subject with craniofacial malformation. The mean mandible\u2010implant distances were 5.37 and 5.38\u2009cm, in the right and left ears of the subjects, respectively, and no differences were observed between them, thereby indicating optimal bilateral symmetry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The use of the guide\u2010marker proved to be an effective tool to provide symmetrical placement of bilateral BAHS. We propose a novel method employing a simple guide\u2010marker and tracing based on symmetrical anatomical landmarks to achieve precise placement and optimal symmetry and which may be easily adopted in the surgical routine of BAHS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>3.<\/jats:p><\/jats:sec>","DOI":"10.1002\/lio2.1195","type":"journal-article","created":{"date-parts":[[2023,12,15]],"date-time":"2023-12-15T06:21:33Z","timestamp":1702621293000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Symmetrical placement of bilateral percutaneous bone\u2010anchored hearing systems via guide\u2010marker"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5371-1482","authenticated-orcid":false,"given":"Renata Tadeu Ramirez","family":"Garcia","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Otorhinolaryngology, Head and Neck Surgery, Ribeir\u00e3o Preto Medical School University of S\u00e3o Paulo  Ribeir\u00e3o Preto S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Carlos","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Center for Imaging Sciences and Medical Physics of the Department of Medical Imaging, Hematology and Clinical Oncology, Ribeir\u00e3o Preto Medical School University of S\u00e3o Paulo  Ribeir\u00e3o Preto S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1078-9602","authenticated-orcid":false,"given":"Fabiana","family":"Danieli","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, RCS, Ribeir\u00e3o Preto Medical School University of S\u00e3o Paulo  Ribeir\u00e3o Preto S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9688-782X","authenticated-orcid":false,"given":"Miguel Angelo","family":"Hyppolito","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Otorhinolaryngology, Head and Neck Surgery, Ribeir\u00e3o Preto Medical School University of S\u00e3o Paulo  Ribeir\u00e3o Preto S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,12,14]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749\u20104486.2011.02302.x"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001111"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001235"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.3109\/14992027.2014.880813"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2017.12.002"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2013.11.010"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.3109\/14992027.2011.635315"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1121\/1.428314"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1121\/1.2005847"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2013.01.023"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1017\/s0022215100130816"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e318206fdc0"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2007.12.019"}],"container-title":["Laryngoscope Investigative Otolaryngology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/lio2.1195","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,2,23]],"date-time":"2024-02-23T12:11:23Z","timestamp":1708690283000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/lio2.1195"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,14]]},"references-count":13,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2024,2]]}},"alternative-id":["10.1002\/lio2.1195"],"URL":"https:\/\/doi.org\/10.1002\/lio2.1195","archive":["Portico"],"relation":{},"ISSN":["2378-8038","2378-8038"],"issn-type":[{"type":"print","value":"2378-8038"},{"type":"electronic","value":"2378-8038"}],"subject":[],"published":{"date-parts":[[2023,12,14]]},"assertion":[{"value":"2023-06-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-11-22","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-12-14","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e1195"}}
