Abstract

Background: The sella turcica volume is widely measured by the Di Chiro-Nelson method. The purpose is to compare the fidelity of a proposed volumetry method versus the Di Chiro-Nelson method, using Computed Tomography (CT) images.

Materials and methods: Morphometric examination of 173 CT were included, of which 52.6% were female. The mean age was 53.2 ± 17.6 years. Considering the Di Chiro-Nelson method, two measurements were added for each axis in the CT evaluation: Length (Central, Left, and Right), Width (Central, Anterior, and Posterior), and Height (Central, Left, and Right).

Results: The mean measurements were Length: Central 10.11 ± 1.44, Left 7.45 ± 1.67, Right 7.53 ± 1.59; Width: Central 12.27 ± 2.11, Anterior 10.99 ± 1.92, Posterior 10.10 ± 1.74; Height: Central 7.68 ± 1.38, Left 7.16 ± 1.35, Right 7.40 ± 1.41. A statistically significant difference between sex was found only in the anterior width (p=0.01). Using the proposed method, the volume was 342.2 ± 88.5 and 378. 6 ± 113.9 mm3 respectively between females and males (p=0.02) versus 476.1 ± 132.4 and 523.8 ± 186.0 mm3 (p=0.05) using the Di Chiro-Nelson’s method.

Conclusions: Women had significantly smaller sella turcica volume than men. This proposed method considers the sella turcica as a not strictly symmetrical structure and indicates reduced variation between the maximum and minimum values, compared to the Di Chiro-Nelson’s. Our findings may be useful to reassess the volume of the sella turcica as the measurements indicate a higher precision.
