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.
