Every disease and especially neoplasmatic disease is a source of deep mental experiences. The aim of this study was the establishment of some psychological behavioural parameters in 55 patients who underwent radical neck dissection and in 32 patients operated for other, non-neoplasmatic laryngologic diseases. In order to evaluate psychological state of the patients the following of States and Personality Traits (TISCO), 2. Feeling of Safety Question Sheet (KPB), 3. Profile of Mood States (POMS), 4. Scale of Hopelessness (HS-8). It was stated, that patients after radical neck dissection have deviations concerning indexes of cognitive and emotional behaviour and that there are differences between patients operated as the reason of neoplastic processes and other patients. These differences appear also among persons examined in the period shorter than 1 year from their surgery as opposed to patients operated earlier than 1 year before examinations. The fact of laryngectomy did not appear to have significant influence upon most of the evaluated indexes of cognitive and emotional behaviours.
