[The experience with the reconstruction of the superoposterior wall of the external auditory meatus during stapedoplasty].

The objective of the present study was to improve the effectiveness of stapedoplasty by developing the method for the prevention of the formation of retraction pockets in the tympanic membrane and cicatrical fixation of auditory ossicles. A total of 60 patients presenting with grade I-II otosclerosis and conductive or mixed-type hearing impairment were surgically treated during the period from 2008 to 2014. Twenty four of these patients had undergone stapedoplasty in the preceding period in different clinics that either failed to improve their conditions or resulted in their deterioration.

[The possibilities for the application of the fluoroplast-based prostheses with a diamond-like carbon nanocoating in ear surgery (an experimental study)].

The objective of the present study was to elucidate general and local characteristics of the tissue reactions to the implantation of radiation-modified polytetrafluoroethylene (PTFE)-based fluoroplast F-4PM20 with a diamond-like carbon (DLC) nanocoating or with the diamond-like carbon coating containing the dispersed nano-sized silver particles to the experimental animals (rats). A total of 150 inbred white rats were included into the experiment; they were divided into 3 groups comprised of 50 animals each. The rats in group 1 were implanted with the 5 nm thick strips of fluoroplast F-4PM20 having the diamond-like carbon nanocoating.
