ABSTRACT
Chronic otitis media is one of the most common ear pathologies among children. This article provides a short overview of publications on surgical techniques. Currently, the most effective treatment is the surgical sanitation of the middle ear cavities. There are two fundamentally different approaches of operations in relation to the posterior wall of the external auditory canal - «open¼ and «closed¼ types. Both methods have their advantages and disadvantages, which are especially noticeable in pediatric revision otosurgery. Surgical obliteration of the sanitized middle ear cavities is an effective compromise option. However, the techniques of bone obliteration, which are actively applied among adults, are difficult if we discuss children ear. A way out of this situation may be the use of modern osteoplastic materials for filling large trepanation cavities. The article describes in detail the technique of revision sanitizing surgery on the middle ear using osteoplastic granules. Purpose of the study. The analysis of the first results of separate obliteration of paratympanic cavities in children using osteoplastic materials. MATERIAL AND METHODS: In the period from May 2018 to November 2020, on the basis of the Federal State Autonomous Institution «National Medical Research Center of Children's Health¼ of the Ministry of Health of Russia, 28 children aged from 6 to 17-year-old with chronic otitis media and cholesteatoma were operated using osteoplastic obliteration, who had previously sanitizing operation on the middle ear. All children on admission to the hospital and 6-12 months after the operation underwent a complex examination. The condition of each patient was assessed using the OMO-22 quality of life questionnaire, to which the parents answered the questions twice - before and 1 year after surgery. RESULTS: During the postoperative period none of the patients had clinical signs of recurrence of cholesteatoma, which was confirmed by CT scan. When assessing the quality of life of children using a questionnaire, the average score before the operation was 130.2±27.7, after the operation - 61.5±21.1. The indicator of the bone-air interval before surgery in patients averaged 29.8±9.7 dB, 1 year after surgery - 13.0±10.9 dB (p>0.05). FINDINGS: The first experience of using osteoplastic materials for obliterating the paratympanic spaces in children has shown high efficiency, ease of use and safety.
