[Retrofacial approach to remove a rare chondromyxoid fibroma of the infralabyrinthine space]. / Udalenie redkoi khondromiksoidnoi fibromy infralabirintnogo prostranstva s ispol'zovaniem retrofatsial'nogo dostupa.

A very rare case of 46-yaer-old woman with chondromyxoid fibroma (CMF) of infralabyrinthine area of temporal bone was described in this article. The only manifestation of this disease was a severe temporary pain in the postauricular area with irradiation in the occipital bone and headache during the last 3 months. A detail description of the CT scan and MRI data was presented. Tumor removing was performed through the retrofacial approach with combination of the microscopic and endoscopic assistance technique, which allows to had a good visualization and controlling of tumor separation from the vital structures with hearing and facial nerve function preserve. Also, we presented a brief review of literature with differential diagnosis of the CMF of the temporal bone, which conducted to minimize the diagnosis mismatches in the otologic and head and neck practice and to optimize the treatment of patients with such tumor.

[Key points of 'Noise-induced hearing loss' clinical guidelines]. / Osnovnye polozheniia klinicheskikh rekomendatsii 'Poteria slukha, vyzvannaia shumom'.

In this article we present the key points of 'Noise-induced hearing loss' clinical guidelines, which are included to the Clinical Guidelines Classifier of the Ministry of Health of Russia (2018). We give the definition of 'Noise-induced hearing loss', disclose the main causes and pathogenetic features of hearing impairment in employees who are affected by intensive noise at work. We state the main clinical and diagnostic criteria, treatment and rehabilitation principles; present the basics of primary and secondary prevention of hearing impairment in 'noise-hazardous' workers. We also disclose in detail the algorithm of expertise of hearing diseases connection with the profession on the stages of preliminary and final professional disease. Professional suitability issues are also discussed. Clinical guidelines contain a unified classification of noise-induced hearing loss severity complied with international approaches and medical and social expertise criteria.

[The results of universal audiological screening of newborn infants in the Astrakhan region]. / Rezul'taty universal'nogo audiologicheskogo skrininga novorozhdennykh v Astrakhanskoi oblasti.

We have evaluated the results of universal audiological screening of 93 352 newborn infants performed in the Astrakhan region of the Russian Federation during the period from 2009 till 2015. The screening coverage amounted to 95%. The prevalence of hearing disorders was estimated at 1:1111 and that of their severe forms at 1:3000. The clinical significance of the examination during its first stage consists of the exclusion of evoked otoacoustic emission. After the completion of the second stage, it is necessary to carry out the regular medical follow up observation of the children suffering from hearing impairment and to undertake the early rehabilitative treatment based on the application of hearing aids and prosthetic devices. Sensorineural hearing loss was found to be the predominant form of hearing disorders in the children during the first year of life (80%). The impairment of hearing was documented in 22.3% of the premature children which suggests the necessity of long-term monitoring of evoked otoacoustic emission in these patients.
