[Use of autotransplants and implants in ossiculoplasty].

The paper presents a comparative analysis of efficacy of ossiculoplasty (OP) using different transplants. A total of 202 operations were performed. Prostheses made of the fragments of the auditory ossicles, or a cortical layer of the temporal bone (n=81), of nail plate (n=56), titanium implants (n=65) were applied. A satisfactory result was achieved in 72-87% ossiculoplasties. Functional outcomes of OP did not vary significantly with type and material of the prosthesis. Main causes of poor OP results were fixation or displacement of the prosthesis with fibrous tissue; in case of titanium prostheses -- perforation of the tympanic membrane with prosthesis extrusion.

[Vestibular function after a reconstructive surgery improving hearing in patients after radical operation on the middle ear].

The study included 62 patients who had undergone radical surgery (RS) on the middle ear. The patients were later operated to improve hearing according to the original reconstructive technique. Before the reconstructive surgery and 1-2, 3-6, 12 and 36 months after it combined vestibulometric examination, otomicroscopy, audiometry assessed the treatment efficiency. Perception of live speech was also investigated. Vestibular dysfunction occurred in 87.1% of the examinees with the history of RS. One of the main causes of the dysfunction was micropathological foci in the trepanation cavity located primarily on the medial wall. Surgical reconstruction creates a closed ventilated neotympanic cavity lined with mucosa. This promotes correction of vestibular dysfunction. Vestibular dysfunction late after radical surgery on the middle ear should be, along with hypoacusis, an indication for reconstructive hearing-improving surgery because the latter relieves or eradicates subjective and objective manifestations of the vestibular dysfunction in many previously operated patients.

[On the clinical significance of the trephined cavity status in patients with radical surgery of the middle ear].

303 ears were examined otomicroscopically in 267 patients who had undergone radical operation on the middle ear (RO). Local and general symptoms in patients after RO were defined as "the operated ear disease". Otomicroscopic picture of pathomorphological changes in the trepanation cavity is provided. It is necessary to account for these changes in planning reconstructive surgery.

[Barofunction of auditory tube in patients with central perforation of tympanic membrane].

Patients with otitis media chronica with central tympanic perforation underwent glue myringoplasty or radical operation. In 52.2 and 33.3% of them an original technique developed by the authors, has discovered defect of barofunction of the auditory tube named inflation effect of the auditory tube. High intratympanic pressure observed in this effect should be taken into consideration in tympanoplasty as it underlies rupture or dislocation of the transplant in myringoplasty or dislocation of the neotympanic membrane in reconstructive surgery on the middle ear.

[Histological evaluation of the condition of the trepanation cavity coating after radical surgery on the middle ear].

Tissue samples obtained intraoperatively from different parts of the middle ear in the course of the radical operation (35 cases) or reconstructive operations in patients with the history of surgical intervention on the ear (67 cases) were examined histologically. Fibrous-atrophic changes in the trepanation cavity coating correlated with the duration of the disease and the time since the radical operation. Pathomorphological and topographic profile of the changes in the operated ear coating copies relevant picture of otitis media purulenta chronica. The tympanomastoid cavity coating was characterized by increasing fibrous-atrophic changes reflecting regeneratory-plastic insufficiency of the epithelium and persistent tympanofibrosis in conditions of open trepanation cavity with disturbed anatomic relations in the middle ear.
