“…However, there are still some skin problems related with percutaneous devices, mainly in tropical countries where the weather is warm and humid. Also, many patients do not wish to use percutaneous devices for aesthetic reasons [19][20][21] . Recently, transcutaneous passive devices are being more frequently prescribed; it has been reported that they cause slight pressure irritation of the skin between the implants and the external base plate [22] .…”

OBJECTIVE:To demonstrate the surgical technique and audiological results of a middle ear implant for restoring hearing in patients with bilateral aural atresia and microtia with conductive or mixed hearing loss. MATERIALS and METHODS:In this prospective study, 12 subjects aged 12 years and older presenting with hearing loss and bilateral congenital aural atresia underwent surgical insertion of a middle ear implant. The patients underwent tympanomastoidectomy with a wide opening of the attic and preservation of the roof of the atresic tympanic bone to expose the middle ear and position the floating mass transducer of the implant.RESULTS: There were no intraoperative or postoperative complications. The hearing threshold averages in a free field were 53.5 dB preoperatively and 25.6 dB postoperatively. Monosyllabic word recognition averaged 61% preoperatively and 91.3% postoperatively. The average speech perception in quiet conditions during the hearing in noise test improved from 67.11 dB to 45.99 dB, and the signal-to-noise ratio improved from 5.64 to 1.31. CONCLUSION:The tested system is an excellent option for auditory rehabilitation of conductive hearing loss due to bilateral ear atresia. The surgery is well structured and safe and provides several alternatives to the surgeon, which is valuable in difficult cases.

“…Depending on the severity of the anomaly, several treatment options are to be considered in children presenting with such altered anatomy: surgical correction of the anomaly if feasible, amplification by means of a conventional hearing aid if possible or a bone conduction device (BCD) in all other cases, or conservatively monitoring the child’s development. When intervention is required, amplification of sound by means of a percutaneous BCD is associated with better audiological outcome than surgical intervention, especially in patients with considerable anatomic deviations [5–7]. …”

Bone conduction devices (BCDs) are advocated as an amplification option for patients with congenital conductive unilateral hearing loss (UHL), while other treatment options could also be considered. The current study compared a transcutaneous BCD (Sophono) with a percutaneous BCD (bone-anchored hearing aid, BAHA) in 12 children with congenital conductive UHL. Tolerability, audiometry, and sound localization abilities with both types of BCD were studied retrospectively. The mean follow-up was 3.6 years for the Sophono users (n = 6) and 4.7 years for the BAHA users (n = 6). In each group, two patients had stopped using their BCD. Tolerability was favorable for the Sophono. Aided thresholds with the Sophono were unsatisfactory, as they did not reach under a mean pure tone average of 30 dB HL. Sound localization generally improved with both the Sophono and the BAHA, although localization abilities did not reach the level of normal hearing children. These findings, together with previously reported outcomes, are important to take into account when counseling patients and their caretakers. The selection of a suitable amplification option should always be made deliberately and on individual basis for each patient in this diverse group of children with congenital conductive UHL.

“…The most consistently reported measure of a successful hearing result was a SRT, PTA, or ABG less than 30 dB HL and average hearing gain [12]. All of our six articles included the results of ABG < 30 dB.…”

“…So far there has been only one systematic review that compared the hearing outcomes of atresiaplasty and osseointegrated bone conduction device (OBCD) [12], and one meta-analysis of the complications associated with osseointegrated hearing aids. But there was no meta-analysis of the complications associated with atresiaplasty and long-term hearing outcomes with prolonged follow-up.…”
