On April 5, 2019 the First Ukrainian-Polish ENT Congress was held in Kiev. The meeting covered issues related to innovative technologies in otorhinolaryngology. The Congress gathered more than 300 doctors from: Ukraine, Poland, Germany, Italy, Kazakhstan, Belarus and Uzbekistan. Poland was represented by 40 participants from the Department of OtorhinolaryngologyHead and Neck Surgery of the Medical University of Warsaw and the Department of Paediatric Otolaryngology of the CMKP, the Department of Otolaryngology of the Bielański Hospital in Warsaw, the Otolaryngology Clinic of the Medical University of Gdańsk and the Department of Head and Neck Neoplasms Surgery of the Medical University of Łódź.
W dniach 13-15 czerwca 2019 roku w Druskiennikach odbył się 5. Litewsko-Polski Kongres Otorynolaryngologiczny. Był on wyrazem wieloletniej współpracy w zakresie spotkań naukowych ośrodków obydwu krajów. Na wspólne zaproszenie profesora Virgilijusa Ulozy, Kierownika Katedry i Kliniki Otorynolaryngologii Litewskiego Uniwersytetu Nauk Medycznych i profesora Kazimierza Niemczyka, Kierownika Katedry i Kliniki Otorynolaryngologii, Chirurgii Głowy i Szyi WUM, odpowiedziało ponad 150 lekarzy z krajów organizatorów, ale również m.in. z Austrii, Wielkiej Brytanii, Białorusi i Czech.
We present a surgical technique of closed tympanoplasty for chronic otitis, together with an intraoperative functional evaluation system with the OssiMon LAIOM software. The technique can be used in one or two steps for an intraoperative evaluation of the functional effect during ear operation. Using OssiMon LAIOM, we were able to simultaneously measure the auditory steady-state response (ASSR), as well as to perform laser dopler vibrometry (LDV). For electrophysiologic measurements, OssiMon LAIOM uses the Intelligent Hearing System platform, and the Polytec single-point laser to evaluate the ossicular mobility. The measurements can be conducted using both methods at the same time or separately, applying each method independently. The OssiMon LAIOM software records the ASSR response intraoperatively and marks it automatically on the audiogram with the preoperative hearing level. The ossicular vibration level is determined based on the measured LDV response. To the best of our knowledge, OssiMon LAIOM is the first solution allowing to objectively measure the effectiveness of tympanoplasty using two methods simultaneously, i.e. ASSR and LDV. The system could be widely applied in the functional evaluation of the middle ear and in clinical practice.
