Early onset hearing loss, the most common sensory disorder, often has a negative impact on the development of communication, language and speech, and the child's-psychosocial development. Early detection, identification and (re)habilitation are crucial in order to minimize this negative impact of hearing loss. The child must be included in the early intervention program, which is defined as the process of providing a wide range of services and support to children and their families. Prerequisites for quality implementation of early intervention programs are timely inclusion, availability of services, family orientation, cooperation among experts, coordination of services, and professional counseling and guidance of parents. Audiologists, otorhinolaryngologists and pediatricians are experts who have the key role in the beginning stages of the early intervention process for children with hearing loss. The greatest risk for omissions in informing and guiding the families is precisely at these initial stages of early intervention. The aim of this work is to gain insight into the perception of audiologists, otorhinolaryngologists and pediatricians' own knowledge about early intervention for children with hearing loss, into the perception of their familiarity with the roles of different experts in a multidisciplinary early intervention team, into the perception of their familiarity about terms related to early intervention and into perception of one's own role in early intervention for children with hearing loss. For the purposes of the research, an online questionnaire was created consisting of 32 questions. A total of 64 participants took part in the research - 49 pediatricians and 15 audiologists and otolaryngologists. The results of the research pointed to the need for additional education of audiologists, otolaryngologists and pediatricians about early intervention in children with hearing loss, given that they perceive their knowledge about early intervention as insufficient and their familiarity with the terms that are important for early intervention and with the roles of most others experts who are involved in early intervention are perceived as superficial.
