Methods of Partial Deafness Treatment

Description

This book presents the revolutionary approach to the treatment of hearing loss proposed by Professor Henryk Skarżyński and developed in collaboration with the group of internationally recognized experts on clinical and experimental otolaryngology, otosurgery, and audiology. The authors present an in-depth look at different aspects of this comprehensive concept of treatment of partial and total deafness with hearing implants, and discuss the approaches to diagnostics and patient selection, results in different groups of patients, the surgical technique, and procedures. This book also covers audiological aspects, auditory training, patient's performance, and psychology. This book is a comprehensive review of the method of partial and total deafness treatment developed and introduced into clinical practice by Professor Henryk Skarżyński. The publication is noteworthy for presenting a multifaceted approach to the subject from related science experts’ and clinicians’ point of view.
