Background: The choice of treatment of the pituitary tumor is the surgical resection. The most common approach is transsphenoidal, with this approach more than 90% of the pituitary tumors can be resected. The complications can be presents until 20%. The most common complications are: Cerebrospinal fluid leak (CSFL), meningeal rupture, meningitis, bleeding, carotid lesion, blindness, insipid diabetes and permanent panhypopituitarism. The aim was review the relationship between the complications and recurrence with the size of the tumor, in the resection by the trans sphenoidal approach.
Results: 32 Patients was included, eighteen were female (56.2%), age average was 45.3 years (sd 14.5), Thirty patients was diagnosed like adenomas (eleven was considered like macroadenomas), one was prolactinoma. The average of the tumor size was 1.14cm. Tree complications were founded, all complications were postoperative nasal bleeding. There were 3 tumor recurrences. There is no statistical relation between the complications and sex, size tumor, age, and surgical approach (p = 0.01), There is no statistical relation between recurrence and sex, size tumor an age.
Conclusions: Presence of complications and recurrences are not related to age, tumor size and sex. The retrospective data analysis and a reduced sample were limiting factors of this study.
