“…One BCD was the ADHEAR device (MED-EL, Innsbruck, Austria), where the transducer is glue-attached without pressure using an acrylic plate. The ADHEARs were also applied bilaterally by Ren et al (2021) [28]. The audio frequency range is from 0.25 kHz to 8 kHz and signal processing occurs with automatic adaptive directional microphones (DMs) [32].…”

“…From measurement of ITD and ILD with a self-recording apparatus, Kaga (1992) [55] showed that the ability to localize sound sources rapidly developed between the ages of 5 and 6 years. In addition, for children with bilateral congenital microtia, Ren et al (2021) [28] reported that the improvement in sound localization was also negatively related to the malformation degree of the patient's head. Apart from this, the ability of sound localization can improve with training.…”

“…With regard to this partial re-establishment, they considered that the BB might have provided a relatively stronger stimulation of both cochleae compared with the contralateral ADHEAR. Ren et al (2021) [28] also used ADHEARs bilaterally for 12 children with mild to severe bilateral CHL due to congenital microtia. They stated that unilateral fitting of ADHEAR did not improve the sound localization ability, while bilateral fitting demonstrated instant improvement in half of the patients, in that the root mean square error (RMSE) decreased from 67.9 ± 10.9° (unaided condition) to 33.7 ± 4.9° (bilateral fitting).…”

Sound localization in daily life is one of the important functions of binaural hearing. Bilateral bone conduction devices (BCDs), middle ear implants, and cartilage conduction hearing aids have been often applied for patients with conductive hearing loss (CHL) or mixed hearing loss, for example, resulting from bilateral microtia and aural atresia. In this review, factors affecting the accuracy of sound localization with bilateral BCDs, middle ear implants, and cartilage conduction hearing aids were classified into four categories: (1) types of device, (2) experimental conditions, (3) participants, and (4) pathways from the stimulus sound to both cochleae. Recent studies within the past 10 years on sound localization and lateralization by BCDs, middle ear implants, and cartilage conduction hearing aids were discussed. Most studies showed benefits for sound localization or lateralization with bilateral devices. However, the judgment accuracy was generally lower than that for normal hearing, and the localization errors tended to be larger than for normal hearing. Moreover, it should be noted that the degree of accuracy in sound localization by bilateral BCDs varied considerably among patients. Further research on sound localization is necessary to analyze the complicated mechanism of bone conduction, including suprathreshold air conduction with bilateral devices.

“…Its causative factors are mostly related to viral infections, medications, and preeclampsia in women in early pregnancy [ 5 ]. Microtia is not only a cosmetic and appearance defect but also seriously affects the development of the patient's physical and mental health [ 6 ]. Most patients begin noticing their childhood physical defects, leading to dissatisfaction with their body image.…”

Aims. To investigate the effects of multimedia health education on psychological burden, quality of life, and self-efficacy of patients with congenital microtia. Materials and Methods. Eighty cases of patients with congenital microtia treated and cared for in our hospital from June 2018 to June 2022 were selected according to the numerical table method as retrospective study subjects and divided into 40 cases each in the comparison group and the observation group. The comparison group implemented conventional health education and discharge instruction, and the observation group implemented multimedia health education care to compare the effects of self-efficacy, self-care ability and psychological burden of patients in the two groups. Results. Before care, the two groups had no statistically significant difference in the quality of life scores ( P > 0.05 ). Aftercare, the mental vitality scores, social interaction scores, emotional limitation scores, and mental status of patients in the observation group were significantly higher than those in the comparison group ( P < 0.05 ). Before nursing care, there was no statistically significant difference in the nursing ability and anxiety-depression scores between the two groups ( P > 0.05 ). After nursing care, the health knowledge level, self-care skills, self-care responsibility, and self-concept of the observation group were higher than the comparison group, while the depression-emotional disorder scores were significantly lower than the comparison group ( P < 0.05 ). Conclusion. Routine health education and discharge instruction combined with multimedia health education care can effectively improve the quality of life of patients with congenital microtia, reduce adverse emotions, and improve patients’ sense of self-efficacy.

“…A study compared the average daily wearing time of conventional BCHAs (headband and softband) with an adhesive BCHA and reported an improved median wearing time in the adhesive adapter group compared with that of the conventional BCHA group (8.1 vs. 4.3 h) [Dahm et al, 2019]. Regarding audiological outcomes, some researchers have argued that there is no statistical difference between conventional and adhesive BCHAs [Dahm et al, 2018, Gawliczek et al, 2018, Dahm et al, 2019, Skarzynski et al, 2019, Favoreel et al, 2020, Kuthubutheen et al, 2020, Ren et al, 2021. However, a study on adhesive BCHAs revealed no significant improvement in speech recognition abilities under noisy conditions in patients with SSD [Mertens et al, 2018], whereas studies in other settings with the same test situations reported obvious benefits for patients aided with a softband BCHA [Peters et al, 2021].…”

Introduction: A nonsurgical bone conduction hearing aid (BCHA) is a well-established treatment for children with congenital unilateral microtia and atresia (UMA). To date, limited studies have evaluated the audiological characteristics of the different wearing modes in the same nonsurgical BCHA. Methods: Eighteen patients with UMA aged 5–24 years were included. Warble tones at frequencies of 0.5, 1, 2, and 4 kHz were presented to determine functional hearing gain (FHG) of hearing thresholds (in dB HL) in the sound field. The speech perception abilities were assessed by the speech discrimination score (SDS, in %) of monosyllables, disyllables, and sentences in quiet and noise using the Chinese Mandarin speech test materials. Hearing outcomes were evaluated with the ADHEAR™ worn on a softband and with an adhesive adapter. A correlational analysis was conducted to analyze the correlations between variables (e.g., age, height, weight, body mass index [BMI], bone conduction pure-tone threshold, and air conduction pure-tone threshold) and the differences in the two wearing modes. Results: The mean FHG (standard deviation, SD) at 0.5–4 kHz was 20.63 (3.94) dB HL with the adhesive adapter and 26.39 (3.15) dB HL with the softband. When aided with the BCHA, significant improvements in SDS were revealed in all Mandarin speech test material lists either in quiet or noise for both wearing modes. Compared with the adapter mode, the softband provided higher aided SDS values. Correctional analyses revealed that higher BMI values were positively associated with larger delta outcomes between the two coupling methods of the softband and adhesive adapter in patients with UMA. Furthermore, a larger delta average FHG of 0.5–4 kHz was consistently associated with larger delta monosyllabic SDS in quiet, disyllabic SDS in quiet, and disyllabic SDS in noise. Discussion: To the best of our knowledge, this is the first study to compare the hearing benefits of coupling methods using novel adhesive adapters and conventional softbands with the same audio processor (ADHEAR™). Under uniform internal settings, softband integration provided more hearing benefits than adhesive adapter integration, and the differences were more obvious in patients with higher BMI values. Besides, a brief measurement of FHG can be utilized to predict individualized speech perception levels.
