Objective: To investigate the clinical effects of single-stage auricular reconstruction and hearing rehabilitation in children with microtia and external auditory canal atresia. Methods: Sixty eight cases of microtia with external auditory canal atresia (53 males and 15 females, age from 7 to 12 years, with a median age of 8.8 years), who received operations in Shanghai Ninth People's Hospital, Shanghai Jiaotong University School of Medicine from July 2017 to December 2019 were collected.A total of 28 cases received auricle reconstruction with high-density polyethylene (Medpor) framework and hearing reconstructions, among which 20 patients received the traditional external auditory canal and middle ear repair (EACR), and eight patients were implanted bone conduction device bone bridge(BB) simultaneously.In the control group, 40 patients only received Medpor frame implantation for auricle plasty. Postoperative changes in auricle morphology and auditory function and postoperative complications were evaluated. Results: After three to thirty months follow-ups, the auricles shape recovered well in all three groups. The average scores of 14 fine structures in the auricles were 9.43(EACR) and 10.67(BB) points. The average score of auricle symmetry were 6.83(EACR) and 6.00(BB) points. There was no significant difference compared to the auricle reconstruction group (8.23/6.20 points). P>0.05. After surgery, the average hearing improvement in the BB group was 43.33 dB HL and the average speech recognition threshold declined 42.28 dB HL. In the EACR group, the average hearing improvement was 4.13 dB HL and the average speech recognition threshold declined 11.36 dB HL. No vertigo, tinnitus, cerebrospinal fluid leakage and other complications occurred in all the patients. In the EACR group, sensorial hearing loss, auricle stent fracture, ear canal restenosis and ear canal atresia occurred in one patient respectively. In the auricle group, one auricle stent exposure and one facial branch nerve injury occurred. Nearly ten patients had difficulty in hair growth at scalp incisions. Conclusions: The operation of single-stage auricular reconstruction and hearing rehabilitation for microtia is feasible. The methods of hearing reconstruction should be determined by evaluating the development of the inner and middle ear of the patients. For those with poor mastoid development, bone bridge implantation is recommended to achieve a stable and significant hearing effect.

Objective: To observe the clinical effect of auricle reconstruction in adult patients with microtia and summarize the experience. Methods: Clinical data of adult patients with microtia who underwent total auricle reconstruction using the modified Nagata's two stage for microtia reconstruction from June 2016 to June 2021 were analyzed. A total of 41 adult patients (42 ears) with microtia were enrolled, including 30 males and 11 females, with the median age at the time of surgery of 37 years. Autogenous costal cartilage was used as the auricular framework for all patients in this group. The first stage surgery was performed according to the modified Nagata's two stage for microtia reconstruction procedure,cartilage auricular framework carving was performed by different methods according to the ossification state of adult costal cartilage. Six months following the primary operation, ear elevation and cranioauricular angle formation, retroauricular facial flap transfer and medium-thick skin grafting were performed in the second stage. Results: All patients successfully completed two stage operation. During the follow-up of 3 months and 24 months, all the 41 patients were satisfied with the morphology of reconstructed auricle. Conclusion: According to the costal cartilage status of adult patients, different costal cartilage carving techniques can be used for total auricle reconstruction to obtain ideal surgical results.

OBJECTIVETo investigate the validity and feasibility of consecutive three-stage surgical technique of combining auricle reconstruction with external auditory canal atresia reconstruction in patients with congenital microtia-atresia, and to assess the post-surgery results by cosmetic and hearing aspects.
METHODSFrom Sep. 2007 to Jun. 2011, all 74 patients (79 ears) with congenital microtia-atresia treated in our department were enrolled in this study. They consecutively accepted the following three-stage surgical technique: The first stage was Brent' s technique as follows, rib cartilage graft harvest, framework fabrication, and implantation. The second stage combined transfer of the lobule with meatoplasty and tympanoplasty. The third stage was the elevation of the reconstructed auricle. Both the cosmetic and functional hearing results were recorded at follow-ups.
RESULTSAmong these patients, 60 patients (78.5%), 62 ears, acquired extremely satisfactory cosmetic results; 10 patients (16.5%), 13 ears, acquired acceptable cosmetic results; while the remaining 4 patients (5.1%) acquired unsatisfactory cosmetic results. However, the height of elevation of the newly performed auricle framework was not enough due to the existence of newly formed external ear canal. Regarding the hearing results, there were 69 ears with followup audiograms. An air-bone gap (ABG) improvement of 12.5 dB was achieved. The air-conduction hearing threshold improved (10.9 ± 8.2) dBHL, 37 ears (53.6%) achieved serviceable hearing after surgery, with ABG less than 30 dB. There were multiple complications occurred after surgery with the incidence of 49.4% (39/79).
CONCLUSIONSThe combined three-stage surgical microtia and canal atresia reconstruction technique is a viable choice for some suitable patients with microtia-atresia. However, the incidence of complication after meatoplasty is very high and the hearing restoration is not good enough, which need further investigation for the better results.

Objectives: To evaluate the therapeutic effects of unilateral/bilateral bone conduction hearing rehabilitation in patients with bilateral microtia accompanied with severe conductive hearing loss following staged auricle reconstruction and bonebridge implantation. Methods: Thirty-two patients, including 20 males and 12 females, with an average age of 11.8, who received surgical treatment in Peking Union Medical College Hospital (PUMCH) from March, 2016 to January, 2020 with bilateral microtia-atresia were included. Hearing thresholds, speech perception and high-resolution CT of the temporal bone were evaluated prior to surgery and individualized surgery plans (staged auricle reconstruction and bonebridge implantation) were made. Hearing thresholds and speech perception in quiet and noise (SNR = 5 dB) using unilateral Bonebridge were tested two weeks after the implantation surgery when the Bonebridge was activated and at 3th, 6th, 12th month after activation. Hearing thresholds and speech perception were also tested at least three months after the activation of the Bonebridge under three conditions: unaided, unilateral Bonebridge, and bilateral bone conduction hearing devices (Bonebridge plus contralateral ADHEAR). The international hearing aid assessment questionnaire (IOI-HA) and Glasgow children's benefit questionnaire were used to evaluate the subjective benefits of the patients. SPSS 21.0 software was used for statistical analysis. Results: Among these 32 patients, nine were conducted Bonebridge implantation surgery before auricle reconstruction, six were simultaneously with auricle reconstruction and 17 were implanted after auricle reconstruction surgery. Compared with unaided, the mean hearing thresholds (0.5, 1, 2, and 4 kHz) and speech perception following unilateral BCHD and bilateral BCHD attachment were improved significantly (P<0.05 each). The speech perceptin in noise of bilateral BCHD was better than unilateral (P<0.05 each). The modified questionnaire revealed high levels of patient satisfaction following use of both unilateral and bilateral devices. Conclusions: Individulized surgical procedures involving auricle reconstruction and Bonebridge implantation are safe and effective for patients with bilateral microtia-atresia, solving both appearance and hearing problems. Speech perception in noise is better following bilateral BCHD than unilateral BCHD attachment.
