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 either having conductive (CHL) or mixed hearing loss (MHL) with an average bone conduction (BC) hearing loss of 55â¯dB HL or less, or having 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 in particular 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 (25 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 in unaided condition, with the trial BCHD preoperatively and with Osia® postoperatively with Osia®. The maximum word recognition score (mWRS) unaided and the word recognition score (WRS) with the test system at 65â¯dB SPL were correlated with the postoperative WRS with Osia® at 65â¯dB SPL.RESULTS:
Preoperative prediction of postoperative outcome with Osia® was better using the mWRS than by the WRS at 65â¯dB SPL with the test device on the softband. Postoperative WRS was most predictive for patients with CHL and less predictable for patients with mixed hearing loss with BC-4PTA ≥â¯40â¯dB HL. For the test device on a softband, the achievable outcome tended to a minimum, with the mWRS tending 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 WRS with Osia®, for which the most accurate prediction is obtained using the preoperative mWRS. Prediction accuracy decreases from a BC-4PTA of ≥â¯40â¯dB HL.Key words
