Obliteration of the middle ear cavity in children: the current state of the problem and our first experience

Abstract

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 Health» 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. 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). The first experience of using osteoplastic materials for obliterating the paratympanic spaces in children has shown high efficiency, ease of use and safety.
