Neonatal hearing loss is defined as premature hearing loss in newborns and infants, which may be due to a variety of otologic diseases. Dr. Kotzampasakis has extensive experience in the research of neonatal hearing as he has been participating since 2013 in the National Hearing Detection Program of KEELPNO, while he was scientifically responsible for the respective program at Konstantopouleio Gen Hospital of Athens. In the period of 2013-2018, more than 2600 newborns were examined, of whom 4 were diagnosed with neonatal hearing loss and were referred to specialized centers for neonatal hearing loss (1/1000 newborn).
