Ten-year retrospective evaluation of therapeutic choices and related satisfaction in patients with auricular deformities.

To adequately counsel future patients with auricular abnormalities, this study aimed to analyze the therapeutic choices patients make after consultation concerning their auricle and/or hearing. All patients who visited the auricle consultation between January 2010 and January 2020 were included. This comprises patients with all types of auricular anomalies of both congenital and acquired etiology. Follow-up was performed by telephone to obtain informed consent and to take a short nonvalidated questionnaire regarding their therapeutic choices and satisfaction with these choices. Patient characteristics and information regarding therapeutic choices after consultation were subsequently obtained from the patients' medical files. The main outcome parameters were the patients' therapeutic choices regarding the auricle and hearing. A total of 134 patients (61.2%) were included with a mean follow-up of 3.85 years. For congenital and acquired etiologies, 72.8% and 18.2% declined reconstruction, 14.0% and 18.2% chose autologous, 5.3% and 0% chose alloplastic, 6.1% and 45.4% chose prosthetic, and 1.8% and 18.2% chose another type of reconstruction, respectively. A total of 54.9% declined hearing rehabilitation, while 38.2% chose percutaneous bone conduction device (BCD), 2.0% transcutaneous BCD, and 4.9% BCD on a softband. The overall satisfaction score was 8.7/10 concerning the auricle and 8.3/10 regarding hearing. In conclusion, most patients with a congenital etiology chose to wait or decided against auricular reconstruction, while patients with acquired etiologies mostly opted for reconstruction by a prosthesis. Patients or their caregivers were very satisfied with their choice, regardless of whether this implies reconstruction or no reconstruction, which emphasizes the importance of shared decision-making and thorough counseling.

Sound localization with bilateral bone conduction devices.

PURPOSE: To investigate sound localization in patients bilaterally fitted with bone conduction devices (BCDs). Additionally, clinically applicable methods to improve localization accuracy were explored. METHODS: Fifteen adults with bilaterally fitted percutaneous BCDs were included. At baseline, sound localization, (un)aided pure-tone thresholds, device use, speech, spatial and qualities of hearing scale (SSQ) and York hearing-related quality of life (YHRQL) questionnaire were measured. Settings to optimize sound localizing were added to the BCDs. At 1 month, sound localization was assessed again and localization was practiced with a series of sounds with visual feedback. At 3 months¸ localization performance, device use and questionnaire scores were determined again. RESULTS: At baseline, one patient with congenital hearing loss demonstrated near excellent localization performance and four other patients (three with congenital hearing loss) localized sounds (quite) accurately. Seven patients with acquired hearing loss were able to lateralize sounds, i.e. identify whether sounds were coming from the left or right side, but could not localize sounds accurately. Three patients (one with congenital hearing loss) could not even lateralize sounds correctly. SSQ scores were significantly higher at 3 months. Localization performance, device use and YHRQL scores were not significantly different between visits. CONCLUSION: In this study, the majority of experienced bilateral BCD users could lateralize sounds and one third was able to localize sounds (quite) accurately. The localization performance was robust and stable over time. Although SSQ scores were increased at the last visit, optimizing device settings and a short practice session did not improve sound localization.

Autologous versus prosthetic nasal and auricular reconstruction - patient, professional and layperson perceptions.

The aim of this study was to retrospectively evaluate the perceptions of aesthetic outcome following the autologous and prosthetic reconstruction of nasal and auricular defects among patients, professionals (oral and maxillofacial surgeons and ear, nose and throat surgeons) and people unfamiliar with reconstructive surgery. The influence of anatomical subunits on the overall perception of nasal and auricular reconstructions was also determined. A total of 119 patients treated for nasal and auricular defects between 1997 and 2016, with a minimum follow-up period of 6 months, were selected, and photographs of 77 of these patients (65%) were presented in a digital survey and reviewed using a standardized questionnaire. No clinically relevant correlations were found between the age or gender of patients (as well as those of the respondents) and their scores. Prosthetic reconstructions of nasal and auricular defects were considered advantageous over autologous reconstructions in terms of the subjective aesthetic outcome in the view of the professionals, in particular oral and maxillofacial surgeons; however, the patients judged both techniques to be equally effective in terms of aesthetics. No anatomical subunits were found to have a significant impact on the overall match of a nasal or auricular reconstruction with the patient's face.

The efficacy of bone-anchored hearing implant surgery in children: A systematic review.

OBJECTIVE: To evaluate the efficacy of Bone-Anchored Hearing implants (BAHIs) in children and to elucidate the usage and outcomes of new surgical techniques and implants in this specific population. DATA SOURCES: Embase and PubMed. STUDY SELECTION: We identified studies evaluating surgical outcomes of BAHIs in children. Retrieved articles were screened using predefined inclusion and exclusion criteria. Critical appraisal included directness of evidence and risk of bias. Studies that successfully passed critical appraisal were included. DATA EXTRACTION: Outcome measures included patient demographics, follow-up time, surgical technique (one-versus two-stage surgery), tissue handling technique (reduction versus preservation), type of implant used, and complications. DATA SYNTHESIS: We selected 20 articles published between 2000 and 2017 for data extraction, encompassing 952 implanted BAHIs. The overall mean age at implantation was 8.6 years (range, 2-21 years). Adverse soft-tissue reactions occurred in 251 of the 952 implants (26.4%; range 0%-89% across studies). Revision surgery was performed in 16.8% (142 of the 845) of the implants. The total rate of implant loss, i.e. caused by OIF (n = 61), trauma (n = 33), recurrent infection (n = 15), elective removal due to insufficient benefit (n = 1), cosmetic reasons (n = 1), or unknown reason (n = 16), was 13.3% of the implants (127 out of 952; range 0%-40% across studies). Differences are seen in the type of implants used; wide-diameter implants seem to be superior in terms of implant survival, and similar in terms of adverse skin reactions, while one-stage surgery and soft-tissue preservation do not seem to result in higher implant loss rates or increased adverse skin reactions based upon limited amounts of literature. CONCLUSION: In general, BAHIs are a safe method for hearing rehabilitation in children, although large differences between studies are observed. The outcomes of new surgical techniques and implant designs in the pediatric population seem promising, but more research is needed before definitive conclusions can be drawn.

Percutaneous bone-anchored hearing implant surgery: linear incision technique with tissue preservation versus linear incision technique with tissue reduction.

OBJECTIVES: To identify differences in skin thickening and soft tissue reactions between the linear incision technique with tissue reduction (LITT-R) and the linear incision technique with tissue preservation (LITT-P). STUDY DESIGN: Retrospective cohort study. METHODS: All adult patients who underwent the LITT-R or LITT-P between August 2005 and December 2016 at a large general teaching hospital with a minimum follow-up of 6 months were included. RESULTS: A total of 83 implants were included using the LITT-R with a median follow-up of 74.0 months. In the LITT-P cohort 58 implants were included with a median follow-up of 16.5 months. Skin thickening was seen in seven implants (8.4%) in LITT-R cohort and 11 implants (19.0%) in the LITT-P cohort in the first 2 years of follow-up (p = 0.024). Skin thickening in need of treatment was registered in 5 (6.0%), respectively, 6 (10.3%) implants (p = 0.100). Moreover, treatment was successful in all cases. A soft tissue reaction (Holgers ≥ 1) was noticed in 28 (33.7%) implants in the LITT-R group compared to 16 implants (27.6%) in the LITT-P group (p = 0.679). An adverse soft tissue reaction (Holgers ≥ 2) was registered in 16 (19.2%), respectively, 2 (3.4%) implants. This difference was significant (p = 0.040). CONCLUSION: LITT-P has a significantly higher rate of skin thickening and LITT-R has a significantly higher proportion of adverse soft tissue reactions. Nevertheless, combined with the advantages of LITT-P described in other studies, this can be advocated as the preferred technique.

Evaluation of an abutment-level superpower sound processor for bone-anchored hearing.

OBJECTIVES: Performance of an abutment-level superpower sound processor for bone-anchored hearing, the Ponto 3 SuperPower from Oticon Medical (BCD2), was compared to an earlier model from Oticon Medical (BCD1). DESIGN: A comparative study in which each patient serves as its own control. SETTING: Tertiary clinic. PARTICIPANTS: Eighteen experienced BCD1 users with profound mixed hearing loss. MAIN OUTCOME MEASURES: Speech reception thresholds in noise; APHAB and SSQ questionnaires. RESULTS: In a group of 18 patients with severe mixed hearing loss, the performance of a recently introduced bone conduction device (BCD2) is evaluated relative to that of an earlier model (BCD1). Speech reception thresholds for the sentence-in-noise test in the speech and noise frontal condition are not significantly different (P > .05) for BCD1 and BCD2. Speech reception thresholds for frontal speech and three identical noise sources are 1.7 dB lower for BCD2 than for BCD1 (P < .05). With the APHAB questionnaire, the score for background noise is significantly lower (P < .01), that is more favourable, for BCD2 than for BCD1 with an effect size of 0.91. The APHAB domain scores for ease-of-communication, reverberation and aversiveness of loud sounds are not significantly different for both devices (P > .05). Scores for the speech, spatial and quality of hearing domains of the SSQ questionnaire are significantly higher (P < .01), that is more favourable, for BCD2 than for BCD1 with effect sizes of 1.22, 0.71 and 1.05, respectively. Scores for the SSQ-factors "speech understanding," "spatial," "clarity, separation and identification" and "listening effort and concentration" were all significantly higher (P < .05) for BCD2 than for BCD1, with effect sizes of 1.28, 0.64, 0.98 and 0.78, respectively. On a proprietary questionnaire, 16 patients indicate a preference for BCD2 over BCD1 for conversations in a small group and two patients have no preference for either device. In a large group, one patient prefers BCD1, six patients have no preference, and eleven patients prefer BCD2. When listening to music, all patients prefer BCD2 over BCD1, with a strong preference for BCD2 for seven patients. When asked for an overall preference, all patients prefer BCD2 over BCD1, with nine patients strongly preferring BCD2. CONCLUSIONS: The lower speech reception thresholds in noise with BCD2 relative to BCD1 can be attributed to the "speech omni" directionality mode of BCD2. The combination of an improved directionality for primarily low-level inputs and a higher maximum force output, relevant for mid- and high-level inputs, results in a clear preference for BCD2 over BCD1.

On the evaluation of a superpower sound processor for bone-anchored hearing.

OBJECTIVES: Performance of a superpower bone-anchored hearing aid (Baha), the Baha Cordelle from Cochlear Bone-Anchored Solutions (BCD1), was compared to its successor, the Baha 5 SuperPower (BCD2). DESIGN: A comparative study in which each patient served as its own control. SETTING: Tertiary clinic. PARTICIPANTS: Ten experienced BCD1 users with profound mixed hearing loss. For comparison, data from another study with 10 experienced users with a severe mixed hearing loss using a Cochlear Baha 5 power sound processor (BCD-P) were included. MAIN OUTCOME MEASURES: Speech reception thresholds in noise and APHAB and SSQ questionnaires. RESULTS: Speech reception thresholds for the digits-in-noise (DIN) test were significantly lower (P < 5%), that is more favourable, for BCD2 in the speech and noise frontal condition and in the speech frontal and noise contralateral condition than for BCD1. For the group with severe mixed loss fitted with BCD-P, the SRTs were not significantly different (P > 5%) from the BCD2 values. With the APHAB questionnaire scores were significantly lower, that is more favourable, for the ease of communication (P < 5%) and the background noise (P < 1%) domains for BCD2 than for BCD1. APHAB scores for the aversiveness of loud sounds domain were not significantly different for both devices (P > 5%). Scores for the speech and quality domains of the SSQ questionnaire were significantly higher, that is more favourable, for BCD2 than for BCD1. APHAB and SSQ scores for BCD-P were not significantly different from those for BCD2 (P > 5%). CONCLUSIONS: Data for BCD2 in profound mixed loss are similar to those for BCD-P and a severe mixed loss. Of 10 patients, 2 expressed a strong preference for BCD2 over BCD1, and 7 patients had a preference for BCD2 over BCD1. One patient preferred BCD1 because of its built-in telecoil facility.

The Baha Softband. A new treatment for young children with bilateral congenital aural atresia.

The Baha (bone-anchored hearing aid) Softband appears to be an effective mean of hearing rehabilitation for children with a congenital bilateral aural atresia who are too young for the amplification of a Baha on an implant. The aided hearing threshold with a Baha Softband is almost equal to that achieved with a conventional bone conductor. The speech development of the children studied with a Baha Softband is on a par with peers with good hearing.
