Abstract:
Endoscopic transnasal access to the skull base, both for treatment and reconstruction, can cause olfactory morbidity. Knowing the main consequences of this intervention is essential to have objective criteria for decision-making regarding the appropriate surgical technique.The aim of this study is to determine the impact on olfactory function of the endonasal endoscopic access to the skull base with the creation of the nasoseptal flap.

METHODS
A prospective research was carried out in which 22 patients who underwent endoscopic transnasal surgery at the skull base, with the creation of a nasoseptal flap. The Connecticut Chemosensory Clinical Research Center test was applied before and at the 1st, 3rd and 6th postoperative months.

RESULTS
The results showed that only in the first month of follow-up the mean patient classification was statistically worse than at the other evaluation moments (p<0.05), but there was no mean difference in the Connecticut score classification between the other moments (p>0.05); that is, patients showed worsening in the 1st month and returned to the preoperative mean after the 3rd month of follow-up.

CONCLUSION
The present study showed that the postoperative decrease in olfaction is transient, since the patient's sense of smell returns to pre-surgical values in the 3rd postoperative month.
