[Novel possibilities for the rehabilitation of patients presenting with congenital external and middle ear malformations].

The objective of the present study was to estimate the advantages of cochlear Baha BIA 400 abutments in the intraoperative and early postoperative periods. A total of 10 implantations of the systems with the use of hydroxyapatite bone cement were performed in 9 patients of different age. Stability of the implants and intensity of skin reactions were evaluated. The data obtained indicate that the use of cochlear Baha BIA 400 abutments significantly simplifies and shortens the surgical stage of rehabilitation producing a good cosmetic result. The use of the Osstell instrument made it possible to estimate stability of the implants intraoperatively and evaluate the effectiveness of osteointegration during the follow-up period. Analysis of the results of the study provided a basis on which to improve the quality and shorten duration of the rehabilitative treatment of the patients presenting with congenital external and middle ear malformations. Moreover, the data obtained can be used to develop practical recommendations for the further work in this area.
