Although the frequency of smell disorders after the operations of the anterior communicating @entity438 depends to a large degree on the used surgical approach, several independent of surgery factors may contribute to the postoperative smell tests outcome. THE AIM OF OUR STUDIES: The evaluation of the sense of smell in @entity1 who underwent the operation of @entity438 using pterional approach. MATERIAL AND METHODS: In the retrospective studies the results of smell test of the group of 21 @entity1 operated for @entity438 and 21 healthy volunteers of control group were compared. The @entity1 suffering from neurodegenerative, @entity209 , as well as those with rhinoscopic symptoms of rhinosinusitis and with decreased nasal potency confirmed by anterior rhinomanometry were excluded from the study. RESULTS: During the operations it was possible to anatomically retain olfactory nerves in all operated @entity1 . @entity4838 (severe @entity9905 and @entity4838 ) were detected in 1 (4.7%) @entity1 of the control group and in 6 (28.5%) @entity1 of postoperative group. The mean composite olfactory score in @entity9909 test of the postoperative group was 4.53, and in the control group 5.47 points. The difference did not reach statistic significance (Mann-Whitney test, p = 0.068). CONCLUSIONS: Although pterional approach to anterior communicating artery is relatively low traumatic to olfactory tract, the @entity510 may have an unfavorable effect on postoperative olfactory nerve functioning. Considering the fact, that in spite of thorough examination of the @entity1 , we were not able to exclude from the studied groups all the @entity1 with preoperatively impaired smell, it seems reasonable to perform similar smell test studies in the prospective way.
