ABSTRACT
BACKGROUND:
The active transcutaneous, partially implantable osseointegrated bone conduction system Cochlear™ Osia® (Cochlear, Sydney, Australia) has been approved for use in German-speaking countries since April 2021. The Osia is indicated for patients with conductive (CHL) or mixed hearing loss (MHL) with an average bone conduction (BC) hearing loss of 55â¯dB or less, or with single-sided deafness (SSD).OBJECTIVES:
The aim of this retrospective study was to investigate the prediction of postoperative speech recognition with Osia and to evaluate the speech recognition of patients with MHL and an aided dynamic range of less than 30â¯dB with Osia. MATERIALS ANDMETHODS:
Between 2017 and 2022, 29 adult patients were fitted with the Osia, 10 patients (11 ears) with CHL and 19 patients (21 ears) with MHL. MHL was subdivided into two groups MHLI with four-frequency pure-tone average in BC (BC-4PTA) ≥â¯20â¯dB HL and <â¯40â¯dB HL (nâ¯= 15 patients; 20 ears) vs. MHL-II with BC-4PTA ≥â¯40â¯dB HL (nâ¯= 4 patients; 5 ears). All patients tested a bone conduction hearing device on a softband preoperatively. Speech intelligibility in quiet was assessed preoperatively using the Freiburg monosyllabic test unaided and with the test system and postoperatively with Osia. The maximum monosyllabic score (mEV) unaided and the monosyllabic score with the test system at 65â¯dB SPL were correlated with the postoperative monosyllabic score with Osia at 65â¯dB SPL.RESULTS:
Preoperative prediction of postoperative outcome with Osia was better using the mEV than the EV at 65â¯dB SPL with the test device on the softband. Postoperative EV was most predictive for patients with CHL and least predictive for patients with mixed hearing loss with 4PTA BC ≥â¯40â¯dB HL. For the test device at softband, results tended to show the minimum achievable outcome and the mEV tended to predict the realistically achievable outcome.CONCLUSION:
Osia can be used for the treatment of CHL and MHL within the indication limits. The average preoperative bone conduction hearing threshold also provides an approximate estimate of the postoperative EV with Osia, for which the most accurate prediction is obtained using the preoperative mEV. Prediction accuracy decreases from a BC-4PTA of ≥â¯40â¯dB.
