The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

Loudness Summation

A new non-invasive adhesive bone conduction hearing device (ABCD) has been proposed as an alternative solution for reversible bilateral conductive hearing loss in recurrent or long-lasting forms of otitis media with effusion (OME) in children that cannot undergo surgical treatment. Our aim was to assess the effectiveness of ABCD in children with OME. Twelve normal-hearing Italian-speaking volunteers, in whom a conductive hearing loss was simulated, participated in the study. The free-field average hearing threshold was determined and, to evaluate binaural hearing skills, loudness summation and the squelch effect were assessed. Five conditions were tested: (1) unaided without earplugs, (2) unaided with bilateral earplugs, (3) aided right ear with bilateral earplugs, (4) aided left ear with bilateral earplugs, and (5) bilateral aid with bilateral earplugs. Post-hoc analysis showed a significant statistical difference between plugged, unplugged, and each aided condition. The main results were a better loudness summation and a substantial improvement of the squelch effect in the bilaterally aided. Our results suggest that ABCD is a valid treatment for patients with conductive hearing loss that cannot undergo bone conduction implant surgery. It is also important to consider bilateral aids in order to deal with situations in which binaural hearing is fundamental.

ntroduction: Bone conduction implants are currently used for rehabilitation of conductive and mixed hearing loss as well as for single sided deafness. A growing number of these implants available on the market increases requirements on detailed knowledge on their technical properties, and on their advantages and disadvantages in clinical practice. Sophono is one of the recent members in this implant group. The aim of the study is to summarize our first experiences with Sophono at our implantation center in Bratislava. Patients and methods: We present data of the first two adult patients who underwent Sophono implantation. Both suffered from bilateral conductive hearing loss of different etiology. We focused on their audiological functional outcomes, basic surgical aspects and subjective assessment by the patients. Results: In free field tone audiometry with the implant, both patients achieved improvement of hearing thresholds by 21.25 dB and 31.25 dB, respectively. In speech tests with and without noise, we also demonstrated a clear benefit of the implant, which was in a narrow relationship with the degrees of their hearing loss: speech discrimination scores in noise were 30% and 60% in patients 1 and 2, respectively. The surgical procedure in Sophono implantation is relatively simple and does not include any work on middle ear structures. Patient satisfaction with the implant does not always correspond to the measured functional outcomes. Conclusion: The Sophono implant represents a suitable option for rehabilitation of conductive and mixed hearing loss as well as single sided deafness in selected patients. The candidate selection is always based on comprehensive assessment in which the audiological results are an elementary criterion, but definitely not a single one.
