Precise Location of Sellar Floor of Patients With Different Saddle Forms for Pituitary Surgery Through Unilateral Endonasal Transsphenidal Approach

Abstract

Our study aims to illustrate the precise location of sellar floor of patients with different saddle forms for pituitary surgery through unilateral endonasal transsphenoidal approach, by measuring 2 angles and 2 distances. One hundred thirty-three (74 men and 59 women) participated in this study anonymously. Results are as follows: the differences of distances 1, 2, and 3 were statistically significant in comparison of saddle forms (P < 0.05), whereas angles 1 and 2 have no significance. And similar results are also shown in the elderly group and the women. For men, only distance 2 in these parameters was statistically significant. Consequently, we should pay attention to the patients, saddle forms, ages, and sexes, especially for distances 1 and 2 and distance 3 before the surgery, which can help to locate the sellar floor precisely and determine the operable range for patients with different saddle forms.
