“…With dedicated software, the positioning of the BC-FMT can be planned in order to avoid any compression of the sinus and dura, and to locate the screws on the same plane [6,7]. In case of atresia auris, where a pinna reconstruction is planned at a later stage, the incision should be done further posteriorly [8.…”

Objective: To describe our experience with positioning the Bonebridge (BB) device, a semi-implantable transcutaneous bone conduction implant for patients with conductive and mixed hearing loss as well as for those suffering from single-sided deafness. Methods: The following is a retrospective case review of 4 adults suffering from conductive or mixed hearing loss and single-sided deafness. The BB device was implanted unilaterally via 2 different approaches selected case by case: the presigmoid transmastoid and the retrosigmoid approach. An audiological evaluation in the free field was conducted to observe the functional benefit with this device. The Glasgow Health Status Inventory (GHSI) and the Glasgow Benefit Inventory (GBI) questionnaires were filled out to evaluate patients' quality of life in relationship to the intervention. Results: No intra- or postoperative complications were observed. The performance in the speech test in all 4 cases reached 100% in the aided condition at 65 dB, while in the unaided condition at 65 dB, it was less than 10%. The GHSI and GBI questionnaires showed an improvement in quality of life after implantation. Conclusions: The BB device is a safe and effective solution for individuals with pathologies such as chronic otitis media, atresia auris and otosclerosis with inadequate benefit from conventional surgery or bone conduction hearing aids.

“…Posztoperatív utánkövetés is alacsony sugárdózissal biztosítható CBCT-vel. Középfül-implantátum beülteté-sét követő vizsgálatok során a CBCT jobbnak bizonyult a multislice CT-vel összehasonlítva a képminőség tekintetében, mivel kevesebb műtermék keletkezik [20]. Cochlearis implantáció a csökkent fém műtermék miatt megbízhatóbban kontrollálható CBCT-vel [5].…”

A cone-beam komputertomográfia alkalmazása a fül-orr-gégészeti képalkotásban

et al. 2016

A modern fül-orr-gégészetben a pontos diagnózis és a korrekt műtéti tervezés alapja a részletes vizualizációt eredmé-nyező képalkotás. A csontos keretbe zárt struktúrákat gyakran vizsgálják komputertomográfi ával. Az ionizáló sugár-zás veszélyeit fi gyelembe véve az ismételt vizsgálatok hatványozottan növelik a sugárérzékeny szövetek károsodásának kockázatát. A szerzők összehasonlítják a hagyományos és a cone-beam komputertomográfi át, és bemutatják a conebeam komputertomográfi a fül-orr-gégészeti képalkotásban betöltött helyét, előnyeit és korlátait. Összefoglalják a nemzetközi szakirodalomból és saját betegeik vizsgálatából származó tapasztalataikat. Eredményeik szerint a hagyományos komputertomográfi a effektív sugárdózisának töredékével nagy térbeli felbontású vizsgálatok végezhetők tetszőleges síkú és térbeli rekonstrukciókkal. A cone-beam komputertomográfi a megfelelő indikációban kiváló vizsgáló-módszer a fül-orr-gégészeti diagnosztikában. Lényegesen alacsonyabb sugárterhelése miatt a hagyományos komputertomográfi a alternatívája, valamint a per-és posztoperatív betegkövetés hatékony eszköze is lehet, különö-sen az ismételt komputertomográfi ás vizsgálatot igénylő esetekben.

Computed tomography is often used to examine structures within bone frameworks. Given the hazards of ionizing radiation, repetitive imaging studies exponentially increase the risk of damages to radiosensitive tissues. The authors compare multislice and cone-beam computed tomography and determine the role, advantages and disadvantages of cone-beam computed tomography in otorhinolaryngological imaging. They summarize the knowledge from the international literature and their individual imaging studies. They conclude that cone-beam computed tomography enables high-resolution imaging and reconstruction in any optional plane and in space with considerably lower effective radiation dose. Cone-beam computed tomography with appropriate indications proved to be an excellent diagnostic tool in otorhinolaryngological imaging. It makes an alternative to multislice computed tomography and it is an effective tool in perioperative and postoperative follow-up, especially in those cases which necessitate repetitive imaging with computed tomography.

“…To the best of the authors' knowledge, there are no reported studies on either CBCT or CT on flat hearing implants, where the transducer is in contact with bone. A recent human cadaver study [Guldner et al, 2013] concluded that a similar hearing implant, the Bonebridge TM (Med-El, Innsbruck, Austria), and surrounding anatomical structures could be visualized using CT and CBCT, where CBCT had an advantage in image quality. The flat medial surface of the Bonebridge transducer is, however, not in contact with bone.…”

The bone conduction implant (BCI) is a new bone conduction hearing device implanted under intact skin. The transducer has a flat direct contact with the mastoid part of the temporal bone, and no screws are used. The sound signal is transmitted from the external audio processor to the implant by means of magnetic induction. In this study, osseointegration of a flat passive BCI transducer dummy in sheep skulls was assessed using quantitative and qualitative histology as well as cone beam computed tomography (CBCT) and computed tomography (CT). The histology results were also related to the mechanical properties of the bone-to-implant interface. Eight months after the surgical implantation, histology sections of the bone close to the implant showed bone remodeling, compact bone and osseointegration. The histological findings corresponded well to the mechanical measurements indicating stiffer bone close to the implant and unaffected skull vibration transmission. Neither CBCT nor CT had enough resolution to visualize the bone-to-implant interface in detail. In this study, using an animal model, it is shown that a flat implant in contact with bone can be a feasible method for efficient vibration transmission to the skull bone.
