“…We were able to show that the coupling of the FMT to the round window can give an excellent transmission of the vibratory energy to the inner ear and the basilar membrane following an original idea by Colletti et al [16] .…”

Background: Congenital malformations of the auricle are often combined with atresia of the outer ear canal and malformations of the ossicles, representing aesthetic as well as functional deficits. Optimal treatment should therefore address both aspects equally. This report describes a new approach, combining the reconstruction of the auricle with implantation of an active middle ear hearing aid, stimulating the round window membrane. Method: A 33-year-old male patient, with bilateral ear microtia, fibrous atresia of the external ear canals and malformation of the ossicles due to Treacher Collins-Franceschetti syndrome was included in the study. In stage one, the cartilage framework of the new auricle, made of autogenous rib cartilage, was fabricated and implanted. During stage two, the auricle was elevated, a retro-auricular sulcus was formed and a Vibrant MED-EL Soundbridge® device was implanted. The transducer was coupled to the round window membrane. Results: Both functional and aesthetical results were favourable. Aided thresholds were between 15 and 30 dB in the frequency range of 0.75–6 kHz, monosyllabic word understanding at 65 dB SPL increased from 0 to 80%. Discussion: Combining aesthetic and functional rehabilitation, autogenous reconstruction of a new auricle together with the implantation of an active middle ear hearing aid, coupled to the round window membrane, is a promising new approach.

“…Based on computer model calculations and first clinical results reported by Colletti et al [16] , stimulation of the cochlea by coupling of the FMT to the round window membrane (RWM) may be a promising second alternative. Round window stimulation can be regarded as a reversal of the normal pathway of activation of the basilar membrane.…”

“…16 By repositioning the electromagnetic transducer adjacent to the round window, this device is currently being trialled in patients with more complex mixed hearing losses. 17 Two newer, fully-implantable devices, the MET Otologics 'Middle Ear Transducer™' and the Envoy Medical 'Esteem' device, are currently being trialled with promising early results in improvement of speech discrimination and overall patient satisfaction. 19 A cheaper system, arguably easier to fit than the other implantable middle ear devices, is the Soundtec 'Direct Drive'.…”
