Quality-of-life evaluation for patients submitted to nasal endoscopic surgery for resection of pituitary tumours.

PURPOSE: This study aimed to evaluate the pre- and post-operative quality-of-life of patients submitted to the resection of pituitary adenoma via endoscopic transsphenoidal. METHODS: This was a prospective study on patients submitted to endoscopic transsphenoidal pituitary surgery with the harvest of a nasoseptal flap who responded to the questionnaires FV-36 and SNOT-22 in the pre-operative and in months 1, 3 and 6 following the surgical procedure. RESULTS: A total of 42 patients submitted to pituitary adenoma resection surgery via endoscopic transsphenoidal with a nasoseptal flap were recruited. In all of the physical and mental domains (SF-36) evaluated, there was an improvement in the long-term evaluation (6 months), compared to the pre-operative, as well as in the site-specific evaluation (SNOT-22). CONCLUSION: The global and site-specific questionnaires in the 6th post-operative month follow-up presented an important improvement in all the physical and mental domains evaluated, as well as in nasal function in the perception of the patients submitted to pituitary adenoma resection via endoscopic transsphenoidal, demonstrating the safety and efficiency of the procedure.

Relationship Between the Bilateral Removal of the Middle Nasal Turbinate and the Olfactory Function in Endoscopic Skull Base Surgery.

OBJECTIVE: To determine the impact of endonasal endoscopic access to the skull base on the olfaction sense, involving the harvest of a nasoseptal flap, with the removal of the middle nasal turbinate. METHODS: A study was performed on a prospective cohort of 50 patients who underwent transnasal endoscopic surgery of the anterior skull base, with the harvest of a nasoseptal and reverse flap. The patients were divided into 2 groups: partial unilateral removal of the middle nasal turbinate and bilateral removal. Connecticut Chemosensory Clinical Research Center tests were administered before surgery and in months 1, 3, and 6 after surgery. RESULTS: There was no difference in the olfactory sense, when comparing the partial removal of the middle nasal turbinate and the bilateral removal, as well as when comparing the side without the middle nasal turbinate and the side with this structure preserved. There was a worsening in olfaction (P < 0.001) in months 1 and 3 after surgery, returning to baseline in month 6 (P > 0.05). CONCLUSIONS: Bilateral removal of the middle nasal turbinate, compared with unilateral resection, showed no impact on the olfactory function 6 months after surgery. In both groups, there was a transitory decrease in the first month, but this normalized by the sixth postoperative month.
