[Features and results of surgical rehabilitation of hearing loss in osteogenesis imperfecta]. / Osobennosti i rezul'taty khirurgicheskogo lecheniya tugoukhosti pri nesovershennom osteogeneze.

Osteogenesis imperfecta (OI) is a form of congenital osteoporosis. Depending on the type of OI, patients experience various types of hearing loss. Depending on the type and degree of hearing loss, various methods of hearing rehabilitation are used in this category of patients. OBJECTIVE: To evaluate the features and results of surgical rehabilitation of hearing loss in patients with osteogenesis imperfecta. MATERIAL AND METHODS: During the period from 2009 to 2022, 2221 primary stapedoplasty was performed in the department, of which 23 (1.04%) in 21 patients were performed in patients with OI. There were 14 women and 7 men. According to TPA, bilateral hearing loss was detected in 19 patients and unilateral in 2. Conductive hearing loss was observed in 9 cases and mixed - in 14. The average thresholds for bone conduction (BC) were 22.7±8.04 dB, and the bone-air interval (ABG) - 36.1±5.3 dB. According to CT of the temporal bones, all patients showed a bilateral and symmetrical decrease in the density of the auditory ossicles, and in 7 patients there were extensive areas of non-uniform decrease in the density of the bone labyrinth up to +500 - +1000 HU.21 patients underwent 23 operations: in 21 cases stapedoplasty with laser assistance and in 2 cases ossiculoplasty. RESULTS: BC thresholds 6 months after surgery averaged 24.6±8.2 dB, and ABG - 12.1±2.9 dB. Closing of ABG ≤10 dB at spoken frequencies was detected in 30.5%, ABG ≤20 dB - in 95%. After 12 months or more after the operation, no change in the audiological parameters was noted. CONCLUSIONS: Stapes surgery for conductive and mixed hearing loss in OI patients is functionally effective. The best results are achieved after therapy with bisphosphonates with preparations of sodium fluoride, calcium and vitamin D, performing the operation when the density of demineralization zones reaches 1000 HU and using laser assistance. Taking into account the demineralization of the bone structures of the temporal bone, it is recommended to use autocartilaginous stirrup prostheses to restore sound conduction or to cover the attachment area of other prostheses with autologous tissues to prevent necrosis of the long stalk of the incus and stabilize long-term functional results.

[Clinical and radiological classification of otosclerosis]. / Kliniko-rentgenologicheskaya klassifikatsiya otoskleroza.

The article presents various classifications of forms of otosclerosis (OS), which change with the development of diagnostic methods. At the same time, according to the literature, a unified OS classification has not yet been adopted. All existing classifications are imperfect to some extent. The classification of clinical forms of OS according to TPA data makes it possible to determine the indications for surgical treatment and to suggest its possible effect, but not the localization of OS foci. X-ray classifications of localization of OS foci indicate their diversity, distribution, and do not always correlate with the type of hearing loss. At the same time, modern diagnostics of OS should be based on audiological data, localization of foci and their density according to the results of X-ray methods of examination. Based on the examination and treatment of 1532 patients with various forms of OS, a modern clinical and radiological classification of the disease is proposed, based precisely on these provisions. This classification, in our opinion, will improve the quality of diagnosis of various forms of OS, will allow to differentiate the tactics of treating patients with this disease to stabilize hearing loss, indications for surgical treatment, suggest its effectiveness with a reduction in the risk of surgical failures and possible further rehabilitation of the patient.

[Neuroendocrine adenoma middle ear]. / Neiroendokrinnye adenomy srednego ukha.

Neuroendocrine adenoma (NEA) is an extremely rare pathology and accounts for less than 2% of all ear tumors. The article provides an overview of the diagnosis, classification, treatment methods and algorithm for monitoring patients with NEA of the middle ear. 6 cases of NEA of the tympanic cavity are described in detail, which were diagnosed and treated in GBUZ NIKIO named after N.N. L.I. Sverzhevsky DZM for the last 5 years. Diagnosis of NEA of the middle ear is possible when performing high-resolution multislice computed tomography of the temporal bones and magnetic resonance imaging with contrast enhancement, however, the neoplasm can be verified only after a histological examination with the determination of the immunophenotype. Differential diagnosis of NEA of the tympanic cavity with other processes of the middle ear must be carried out at each stage of the diagnostic path. Surgical treatment, depending on the volume of education, allows you to remove it completely and improve the auditory function.

[The effectiveness of transtympanic use of dexamethasone 4 mg in Meniere's disease, severe and moderate course of the disease]. / Effektivnost' transtimpanal'nogo primeneniya deksametazona 4 mg pri bolezni Men'era, tyazhelom i srednetyazhelom techenii zabolevaniya.

The results of transtympanic administration of 4 mg dexamethasone in 37 patients with moderate and severe Meniere's disease are presented. The endolymphatic hydrops was detected in all inner ear structures with predominant accumulation in vestibule and semicircular canals by MRI-visualization before therapy. After 1 month of 4 mg dexamethasone transtympanic therapy the hydrops degree decreased. Daily transtympanic administration of 4 mg dexamethasone for a month leads to reduction of vertigo attacks duration and expression in 92% of cases (follow-up period 24 months) and can be considered when conservative therapy is ineffective before destructive surgical interventions.

[Variants of treatment of the head direction at the festulars of the labi-rint of inflammatory genesis]. / Varianty lecheniia golovokruzheniia pri fistulakh labirinta vospalitel'nogo geneza.

PURPOSE: To analyze the effectiveness of various methods of treating dizziness with fistulas of the labyrinth (FL) of inflammatory genesis. An analysis of the surgical treatment of 216 patients with chronic suppurative otitis media (CSOM) with cholesteatoma complicated by FL using a variety of FL treatment methods is presented. All patients underwent a debridement operation on the middle ear or revision of the postoperative cavity: in 48 patients with a matrix of cholesteatoma in situ on the fistula, in 109 patients with matrix removal followed by plastic repair or FL filling with various autotissues, in 59 patients with matrix conservation, plastic removal or filling FL and SLD labyrinth. In the last two groups, filling of a semicircular canal (SC) defect was performed in 33 patients, and mastoidoplasty - in 47. CONCLUSION: All used FL treatment techniques are effective in the treatment of peripheral vestibular disorders. Careful treatment of SC fistula after removal of all pathological conditions in the absence of active inflammation and the appointment of hormone therapy in the postoperative period are the main factors in preserving the functions of the labyrinth in any surgical technique. Filling of the lumen of the SC and mastoidoplasty in patients with CSOM with FL can eliminate peripheral dizziness.

[The medical assistance seeking behaviour of the patients presenting with suppurative chronic otitis media and their treatment in Moscow]. / Obrashchaemost' i lechenie bol'nykh khronicheskim gnoinym srednim otitom v Moskve.

The objective of the present study was the analysis of the medical assistance seeking behaviour of the patients presenting with suppurative chronic otitis media (CSOM) and their treatment in Moscow during the period from 2009 till 2016. The incidence of suppurative chronic otitis media in the city of Moscow in 2016 was estimated to be 0.14 per 1000 population, its prevalence 1.23 per 1000 population. The materials of the statistical reports of Moscow ENT clinics give evidence of the considerable growth in the number of the admitted patients suffering from ear diseases including suppurative chronic otitis media (mean 5.5). The surgical activity of the ENT clinics with respect to CSOM amounted to 46%. The overall increase in the number of surgical interventions is attributable to a rise in the frequency of reconstructive operations. These data give evidence of excellent continuity in the work of outpatient facilities and ENT clinics, intensification of their activities, and a change of the people's attitude toward the care for their health. Suppurative chronic otitis media is the commonest pathology encountered in the specialized ENT hospitals where it accounts for 59.8% of the total number of ENT diseases. The frequency of the surgical interventions performed for the treatment of CSOM amounts to 98.9%. The enhanced attention given to the patients with this pathology resulted in the two-fold increase of the specialized medical assistance provided to the patients presenting with suppurative chronic otitis media. The most frequently practiced form of the surgical treatment employed for the management of CSOM is tympanoplasty (in 72% of the patients on the average). The 'closed' variants of sanitizing operations are performed in 59.8% of the patients presenting with chronic suppurative otitis media and concomitant cholesteatoma whereas the 'open' interventions are used to treat 45.1% of the patients in need of tympano- and mastoidoplasty. On the whole, the priority surgical treatment of the patients with chronic suppurative otitis media in specialized medical facilities is reconstructive operations intended to simultaneously reach the beneficial sanative and functional effects without deterioration of the quality of life of the patients suffering from chronic suppurative otitis media.

[Desmoplastic fibroma of the temporal bone]. / Desmoplasticheskaya fibroma visochnoi kosti.

[Clinical and roentgenological diagnostics of the severity of mucositis in the patients presenting with chronic suppurative otitis media].

The objective of the present study was to determine the prevalence of mucositis and its roentgenological manifestations in the patients presenting with chronic suppurative otitis media (CSOM). A total of 390 patients with CSOM (mesotympanitis) and 85 ones suffering CSOM with concomitant mucositis were available for the observation. The signs of mucositis were evaluated based on the patients' complaints, results of otomicroscopy, and computed tomography (CT) of the temporal bones. This randomized clinical study involving 390 patients presenting with CSOM revealed the signs of mucositis in 44.6% of the cases. Analysis of the results of temporal bone CT performed in 85 patients with CSOM and mucositis in the absence exacerbation has demonstrated the possibility of detecting mucositis and evaluating its severity from the changes in the airness of the tympanic cavity, attics, and antrum due to the presence of the pathological substrate in these regions.

[The retrospective clinical study of labyrinthine fistula associated with chronic suppurative otitis media and their treatment].

The objective of the present retrospective study was to estimate the efficacy of various surgical techniques employed to treat the patients presenting with chronic suppurative otitis media (CSOM) and concomitant cholesteatoma complicated by labyrinthine fistula. The authors present an overview of the literature concerning diagnostics and results of the surgical treatment of labyrinthine fistula (LF) in the patients with CSOM and concomitant cholesteatoma. The original studies included 157 patients with this condition complicated by labyrinthine fistula. The latter was diagnosed based on the data from medical histories, subjective complaints of the patients, results of otomicroscopy, the presence of fistula symptom verified by the pressure test, results of audiological and vestibulometric studies, and computed tomography (CT) of the temporal bones. Late outcomes of the surgical treatment in the patients presenting with CSOM and concomitant cholesteatoma complicated by LF. All the patients underwent sanitation surgery on the middle ear and revision of the mastoidal portion of the cavity. In 48 of them, cholesteatoma matrix on the fistula in situ was preserved (group 1), in 56 ones the removal of the matrix was followed by plastic correction of labyrinthine fistula using various autogenous tissues (group 2), in 53 patients the cholesteatoma matrix was either removed or preserved with the subsequent sealing of the semicircular canal and selective laser destruction of the labyrinth (LDL) (group 3). 79% of the patients in group 1 had no complaints of dizziness during the postoperative period. There were 78.5% and 96.5% of the patients without such complaints in groups 2 and 3 respectively. The elevation of the hearing threshold following the surgical treatment was documented in 10 (6.4%) patients; it resulted in the deafness in 5 (3%) patients.
