- A problem encountered when using acoustic shock-waves for kidney stone disintegration is that the positioning of the focus relative to a stone, for the best possible fragmenting effect, is crtitical. The standard methods for focus positioning are ultrasound or x-ray imaging. These methods are, however, not always sufficient and a better indication of a well positioned focus would be valuable. The secondary sound emitted as a result of each shock-wave has been found to contain valuable information. A skilled operator is able to hear from the timbre of these sound pulses when the positioning of the focus is adequate. A method for the automatic evaluation of secondary sounds, using a computer, is developed in this work.

- Telemedicine is becoming a reality as a result of improvements in technology and telecommunications. The task of the otolaryngological part of the pilot international telemedicine Litmed project was devoted to the establishment of telemedicine training and demonstration facilities in cooperation between the Departments of Otolaryngology of the Kaunas University of Medicine (Lithuania) and the Lund University (Sweden). The main areas of action of the Litmed project in otolaryngology were: (1) remote rehabilitation of cochlear implant (CI) patients, and (2) phonosurgery and phoniatrics. The main results of the project were as follows: (a) establishment of telemedicine environment for remote on-line collaboration and planned off-line collaboration by use of recorded video laryngostroboscopic images, voice samples, and graphical and computed tomography (CT) data; (b) possibility to carry through telemedicine sessions for pedagogical and speech training support and for cooperative work of speech therapists from Lund and Kaunas with CI patients; (c) remote consultations and discussion of challenging laryngeal cases; and (d) establishment of a technical environment and practical routines for on-line consultations during laryngeal surgery at the Departments of Otolaryngology of Kaunas and Lund. The Litmed project served to assist medical education and research. Tele-otolaryngology helps to keep constant professional contacts with the specialists from abroad and supports an establishment of a center of reference in tele-otolaryngology in Lithuania.
