[The interdisciplinary approach to the rehabilitation of the patients presenting with congenital atresia of the external auditory canal and the concomitant microtia].

The objective of the present study was to develop and introduce into the clinical practice the method for the combined aesthetic and functional rehabilitation of the patients presenting with congenital atresia of the external auditory canal (CAEAC) and the concomitant microtia. A total of 8 patients at the age from 6 to 21 years with unilateral CAEAC and microtia were given the surgical treatment. During the intervention, atresia was resolved using the trans-mastoid approach, tympanoplasty of autofasciae and ossiculoplasty making use of the partial titanium prosthesis and the placement of cranial osteointegratable titanium implants.

[The modern view of the radiodiagnostic methods applied for determining the position of the electrode array in cochlear implantation surgery].

The objective of the present work was to overview the currently available literature publications dealing with the radiodiagnostic techniques applied to evaluate the position of the electrode array used for the purpose of cochlear implantation surgery including both the conventional methods and the recently proposed approaches. It is shown that the intraoperative control guarantees the timely identification of the possible complications and should meet both the safety criteria and the requirements for obtaining high-quality images and intraoperative usability of the surgical instruments being employed. Moreover, the intraoperative monitoring can be exercised under control of fluoroscopy as well as with the use of the portable computed radiography scanners and navigation systems.

The objective of the present study was the prospective analysis of the results of bilateral cochlear implantation (CI) in the children presenting with bilateral ossification of the cochlea after they had survived meningitis. A total of 15 patients underwent the surgical intervention. In those exhibiting bilateral ossification of the basal cochlear helix over the 5 mm segment (up to first bend of the cochlear turn) and partial ossification of the second helix (in 6 children), the affected portions were removed with the placement of two choleostomies, the lower one (from the ossified membrane of the cochlear window) and the upper one (toward the second helix).
