Objective To compare audiometric outcomes, complications, and revisions required for implantable bone-conduction devices (BCDs) versus atresia surgery for the treatment of hearing loss associated with congenital aural atresia. Databases Reviewed PubMed, Scopus, CINAHL. Methods Databases were searched for English articles from inception to July 1, 2022, for studies reporting audiometric outcomes or complications for either BCDs or atresia surgery for the treatment of congenital aural atresia. Main outcome measures included pure-tone audiometry, air-bone gap, speech reception threshold, associated complications, and rates of revision for each treatment option. Results We identified 973 abstracts, of which 89 were selected for data extraction and analysis. A total of 2,611 patients were included, 1,901 in the atresia surgery group and 710 in the BCDs group. A meta-analysis of single means was conducted for age and audiometric outcomes, and a meta-analysis of proportions was conducted for complications and revisions. The average short-term improvement in pure-tone audiometry for the BCDs group was 34.4 ± 1.6 dB compared with 22.4 ± 1.5 dB for the atresia surgery group, representing a significant difference (12.0 dB; 95% confidence interval, 11.9–12.2; p < 0.0001). A smaller proportion of complications were reported in the devices group (16.9%) compared with the atresia surgery group (45.7%). In addition, a smaller proportion of cases in the devices group required some degree of revision (17.8%) compared with the atresia surgery group (23.0%). Conclusions This study demonstrates that implantable BCDs have significantly better audiometric outcomes as well as a lower rate of complications and revisions required compared with atresia surgery.

Rehabilitation of the patients suffering from with congenital malformations of external and middle ear is a specific area of medicine requiring special knowledge and skills of the audiologists and ear surgeons. This article highlights the issues of epidemiology, classification and methods for the rehabilitation of patients presenting with this pathology that reflect our own experience and the methodology based on it for all phases of both functional and aesthetic surgical inerventions. Special attention is given to the assessment of the effectiveness of the treatment, as part of the evaluation of the quality of medical services. The results were demonstrated in 56 patients aged from 5 to 17 years. 32 of them underwent reconstructive, hearing improving surgery (meatotympanoplasty), 24 patients were managed by means of the implantation of the bone-anchored hearing systems. The assessment of the effectiveness of the treatment was conducted according to the algorithm developed by the authors, including free field pure tone audiometry and validated questionnaires for the assessment of the quality of life (the Glasgow Children's Benefit Inventory).

Objective. To study the major acoustic properties of the prototype of bionic ear developed in order to confirm its functional performance. Materials and methods. Acoustic properties of the bionic ear were measured using Random Phase MultiSine signal in a test bench, which simulated the implant-emitter-osseous tissue-inner ear system. The resulting pulse response was converted to the target characteristics: FR and group lag. Experiments were carried out for -6dB signal level, 10 times for each of the methods used. Results. Microtia is a congenital auricular hypoplasia or aplasia (anotia) which often involves impairment or total loss of hearing. One way to rehabilitate this type of patients is to use bone-conducting apparatuses (bone anchored hearing aids), which allow to compensate for the functional component but not to restore facial aesthetics. This paper deals with major acoustic properties of the prototype bionic ear we have previously developed, in order to confirm its functional performance for clinical use. Our analysis of acoustic characteristics of the bionic ear system showed the frequency response was uniform enough in extended voice frequency range (100 to 10000 Hz). The experimental research demonstrated that operating time of the prototype bionic ear to battery depletion is 10 h 26 min with 25 % amplification, 10 h 05 min with 50 % amplification, 9 h 48 min with 75 % amplification. Thus, the acoustic characteristics of the vibratory emitter were determined, which confirmed that the bionic artificial ear was eligible for clinical testing. Conclusions. Major frequency response of the vibratory emitter was measured, and confirmed that preclinical studies were successful and the bionic ear was eligible for clinical testing.
