Simultaneous operations of vibrant soundbridge implantation and auricular reconstruction for patients with microtia and atresia

Objective To discuss the safety and efficacy of simultaneous procedures of vibrant soundbridge implantation and auricular reconstruction with congenital external and middle ear malformation. Methods This is a retrospective study, including 6 patients, 5 boys and 1 girl, aged 7-12 years. All patients received simultaneous operations of vibrant soundbridge implantation and auricular reconstruction. The mean preoperative air conduction threshold was 64.8 dB HL at 0.5, 1, 2, and 4 kHz. The VSB was placed in the third stage of auricle reconstruction, if the soft tissue expansion was performed; otherwise, the VSB was implanted in the second stage. The satisfaction with reconstructed auricle, surgical complications, hearing improvement and speech discrimination scores were evaluated 6 months after surgery. Results All patients and their families reported satisfaction with their reconstructed auricle. There was no complications, including cartilage framework exposion, infection, hematoma, skin flap necrosis, facial paralysis, tinnitus, vertigo or others. Post-operatively, mean VSB-aided hearing threshold was 36.7 dB HL, which was reduced by 28.1 dB HL. The mean speech discrimination scores measured in a sound field with a presentation level of 65 dB SPL and 80 dB SPL were improved. Conclusions The simultaneous operations of auricle reconstruction and Vibrant Soundbridge implantation is an alternative method for patients with congenital microtia and atresia.
