  16  Some patientswho undergo tonsillectomy in Pauls Stradins Clinical University Hospital’s Otolaryngology clinic can experience transient taste disorders during two weeks after operation.  It is necessary to take into account that methods of study are based on patient’s subjective perceptions of his taste (annonymous survey, taste test with chemical solutions).  It is necessary to continue the study in order to get more accurate statistical results. If it is possible, use more objective method, e.g. taste test with more graded chemical solutions. Conclusions
