[Anatomical factors of temporal bone residual cholesteatoma: our experience]. / Osobennosti stroeniya visochnoi kosti kak faktor retsidiva kholesteatomy: nash opyt.

The article describes clinical cases of invasive cholesteatoma of the temporal bone pyramid, leading to a massive destruction of the surrounding structures. Paying attention to the importance of knowing the microsurgical anatomy of critical structures of temporal bone (the anterior bony plate (cog), the tensor tympani fold and the tendon, the tympanic orifice of the eustachian tube, the pretympanic recess, tympanic sinuses) bearing a significance and helping to improve the removal of the invasive cholesteatoma.

[Clinical significance of radiological methods for diagnosing endolymphatic hydrops in Ménière's disease]. / Klinicheskaya znachimost' luchevykh metodov diagnostiki endolimfaticheskogo gidropsa pri bolezni Men'era.

Ménière's disease is a chronic disorder of the inner ear, a permanent sing of which is endolymphatic hydrops. For the diagnosis of Ménière's disease in clinical practice, criteria that are primarily based on the clinical picture. However, instrumental methods for diagnosing Ménière's disease, aimed at identifying endolymphatic hydrops, continue to be developed and improved. Radiation diagnostics contribute significant contribution and aimed at identifying the characteristic signs of Ménière's disease. Recently, it has become possible to visualize endolymphatic hydrops using MRI of the temporal bones. This publication presents an analysis of the current state of this topical aspect of the problem of diagnosing Ménière's disease. The purpose of this review is to conduct a comparative analysis of radiation methods for diagnosing Ménière's disease. MATERIAL AND METHODS: The study included publications in English and Russian found in the PubMed, eLibrary database related to the diagnosis of Meniere's disease. RESULTS: A comparative analysis of computed tomography of the temporal bones, magnetic resonance imaging of the temporal bones and diagnostic possibilities for detecting signs characteristic of Ménière's disease are presented. The most diagnostically significant method of studying Ménière's disease is identified. CONCLUSION: MRI of the temporal bones with contrast enhancement is a promising method that can be used to develop an effective treatment algorithm.

[Cochlear implantation with cochlear otosclerosis with bilateral deafness. Case from practice]. / Kokhlearnaia implantatsiia u bol'noi s otosklerozom i dvustoronnei glukhotoi. Sluchai iz praktiki.

Rehabilitation of patients with sensorineural hearing loss is an urgent task of otorhinolaryngology. One of the diseases leading to a pronounced hearing loss is the cochlear form of otosclerosis. The article describes a clinical case of rehabilitation of a patient with this pathology by means of cochlear implantation. The classification of otosclerosis based on the interpretation of computer tomography of temporal bones is presented.

[The application of mastoidoplasty in repeated scanning operations on the ear].

The objective of the present study was to evaluate the outcomes of mastoid obliteration with the use of the orthotopic bone tissue taken from the linea temporalis region. It was shown that this region is the optimal site at the temporal bone for the harvesting of the plastic bone material to be used in mastoidoplasty during secondary sanitizing surgical interventions on the patients with mastoid cavity problems after canal wall-down mastoidrctomy under conditions of the deficiency of the orthotopic bone tissue. The application of such tissue for the purpose of mastoid-obliteration surgery provides a number of advantages over other methods of mastoidoplasty, in the first place from the standpoint of tissue biocompatibility. Multispiral computed tomography (MSCT) of the temporal bones is a highly informative and non-invasive technique for the study and control of the patients' condition during the late postoperative period following a secondary sanitizing surgical intervention involving mastoidoplasty with the application of the orthotopic bone tissue.

[The morphological study of the Perfoost demineralized bone alloimplant applied for the plastic reconstruction of the posterior wall of the external auditory canal].

The objective of the present study was to enhance the effectiveness of the surgical treatment of chronic suppurative otitis media (CSOM) by means of the application of the Perfoost demineralized bone alloimplant for the plastic reconstruction of the posterior wall of the external auditory canal. This aim was attained by the elucidation of morphological features the Perfoost alloimpalnt at the site of surgical intervention one year after the operation. The study included 12 patients presenting with CSOM (epi- and epimesotympanitis) who had underwent "closed-type" sanation surgery of the middle ear. A Perfoost demineralized bone implant (DBI) plate was used for plastic reconstruction of the posterior wall of the external auditory canal. The secondary intervention within one year after the implantation was used to obtain 5×5 mm biopsy specimens containing a fragment of Perfoost DBI together with the adjacent cicatrical tissue bordering the "living" bone. The biopsies were subjected to standard histological treatment. It was shown that the fragment of the transplanted bone tissue underwent resorption accompanied by neo-osteogenesis. The source of formation of the new bone was fibroblastic elements of connective tissue of the recipient undergoing transformation into osteoblasts under the influence of resorbable components of the alloimplant. The presence of pre-existing bone canals and perforation holes in the implant provides the favourable conditions for its invasion by connective tissue that ensures its strong immobilization and gradual replacement by the newly formed bone tissue which corresponds by "carcass" regeneration. The results of the present study give evidence of the high clinical effectiveness of reconstructive surgery for the treatment of CSOM with the application of the Perfoost demineralized bone alloimplant used for the plastic correction of the posterior wall of the external auditory canal.
