One year after surgery the mean audiological gain in FF PTA4 (pure tone average for 0.5, 1, 2, and 4 kHz) was 52.2 \u00b1 3.5 dB in comparison to the unaided situation, the mean speech understanding with Osia\u00ae in quiet was 90 \u00b1 8.2% for 50 dB SPL, 98.8 \u00b1 2.5% for 65 dB SPL and 100 \u00b1 0% for 80 dB SPL, and the mean speech understanding with Osia\u00ae in noise was 37.5% \u00b1 23.6 for 50 dB SPL, 93.8 \u00b1 4.8% for 65 dB SPL and 98.8 \u00b1 2.5% for 80 dB SPL. There was also an evident improvement in the quality of hearing as well as in the quality of life, measured by APHAB (Abbreviated Profile of Hearing Aid Benefit) and SSQ (Speech, Spatial and Qualities of Hearing Scale). <\/br><\/br> <b>Conclusions:<\/b> The Osia\u00ae is an effective treatment option for patients with bilateral mixed hearing loss. The mid-term audiological and quality of life results are excellent, but further observations including bigger groups of patients and a longer follow- -up are required.<\/jats:p>","DOI":"10.5604\/01.3001.0014.9342","type":"journal-article","created":{"date-parts":[[2021,8,3]],"date-time":"2021-08-03T06:15:17Z","timestamp":1627971317000},"page":"11-22","source":"Crossref","is-referenced-by-count":25,"title":["Piezoelectric bone conduction hearing implant\nOsia\u00ae \u2013 audiological and quality of life benefits"],"prefix":"10.5604","volume":"75","author":[{"given":"Joanna","family":"Marsza\u0142","sequence":"first","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renata","family":"Gibasiewicz","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"B\u0142aszczyk","sequence":"additional","affiliation":[{"name":"Medicus sp. z o.o., Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Gaw\u0142owska","sequence":"additional","affiliation":[{"name":"Medicus sp. z o.o., Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Gaw\u0119cki","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3689","reference":[{"key":"215935r1","unstructured":"Lenarz T.: Cochlear implant \u2013 state of the art.
