“…The use of an active middle ear implant is an option for hearing restoration in aural atresia with microtia; however, there are few descriptions of successful procedures in the literature [8][9][10][11] . In addition, the surgical technique has not been standardized regarding not only the positioning of the active part in the middle ear but also the mastoid or middle-ear approach for any of the available implantable devices.…”

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.

“…Zernotti, et al [27] reported 45 dB of improvement in 14 patients who underwent Bone Bridge implantation. When 34 patients received the BAHA (Cochlear) or Bone Bridge (MED-EL) devices, the average hearing improvement was approximately 35 dB [28]. One singlecenter study directly compared hearing after surgery (n=49) and after BAHA placement (n=19) [29]; the BAHA provided better hearing (≤40 vs. ≤20 dB improvement).…”

Congenital aural atresia is an ear malformation evident at birth, involving various degrees of failed external ear canal development. A true external ear canal is desirable, as devices that replace the canal are inconvenient and expensive. Therefore, an optimal surgical technique is required. Here, we review useful preoperative and operative techniques. Surgical correction is often not the preferred treatment; the hearing outcome is no better than the outcomes afforded by bone-conduction devices, and surgery may be associated with recurrence or complications such as meatal stenosis. Preoperative evaluation and appropriate management are important. Several means of preventing meatal stenosis are discussed in this review.

“…Cochlear implantation is indicated for severe and profound neurosensory hearing loss. [8][9][10] Screening for congenital hearing loss in newborns represents the first and most important step in the evaluation of this condition. 11 Otoacoustic emissions and auditory brainstem response audiometry are used for such screening purposes, the latter often being the preferred method in order to avoid overlooking auditory neuropathy.…”

Introduction: Congenital hearing loss is a multifactorial disease that affects mostly premature newborns exposed to certain risk factors. The recent widespread introduction of newborn hearing screening in Tîrgu Mureș, Romania prompted the need for a multidisciplinary centralized study on the subject. Case series presentation: We collected data from 340 neonates born in 2014 who had undergone neonatal hearing screening with otoacoustic emissions. Our focus group consisted of 137 neonates with a gestational age of less than 37 weeks. We collected data on the pregnancy, birth, and perinatal period, and then analyzed the impact of infections, treatments -with or without ototoxic potential, hypoxia, mechanical ventilation, intrauterine malnutrition, and the presence of malformations. Premature neonates showed a significantly higher number of REFER results than those with a normal gestational age. The rates of low birthweight, head circumference, and infant length; low Apgar scores; hypoxia in the perinatal period; the presence of placental pathology, mechanical ventilation, and perinatal infections; and the concomitant potentially ototoxic treatment were significantly higher in the REFER group. The age of the mother, bilirubin levels, and oxytocin use during birth did not prove to be relevant. Conclusions: Known risk factors can cause hearing loss in a considerable number of newborns and mandate a multidisciplinary approach to the problem at hand. The referral of these patients to an ENT specialist and their correct management according to an individualized hearing recovery plan is crucial
