Normal sizes of the sella turcica of VietNamese on computed tomography

SUMMARY:

Objectives: To determine the normal sizes of the sella turcica of Vietnamese from 1 to 30 y.o. on computed tomography.

Methods: cross-sectional description of retrospective study. The length, depth, width and volume of sella turcica were measured on computed tomography of 705 patients at the No.1 Children’s Hospital and the Trưng Vương Emergency Hospital, HCM city, Vietnam , from January to June, 2011.

Results: The mean size values of the sella turcica were divided into six age groups:1 - 5, 6 - 10, 11 - 15, 16 - 20, 21 - 25, 26 - 30 with length (7.16 ± 1.43 mm, 8.11 ± 1.09 mm, 8.48 ± 1.14 mm, 9.99 ± 1.47 mm, 10.20 ± 1.16 mm, 10.39 ± 1.17 mm); depth (5.74 ± 1.16 mm, 6.74 ± 1.10 mm, 11.35 ± 1.42 mm, 12.67 ± 1.86 mm, 12.73 ± 1.5 2mm, 12.72 ± 1.41 mm); width (9.14 ± 1.67 mm, 10.44 ± 1.41 mm, 11.35 ± 1.42 mm, 12.67 ± 1.86 mm, 12.73 ± 1.52 mm, 12.72±1.41mm) and volume (196.69 ± 85.28 mm3, 286.33 ± 77.18 mm3, 336.19 ± 90.90 mm3, 491.18 ± 146.68 mm3, 500.05 ± 130.09 mm3, 523.80 ± 119.58 mm3).

Conclusions: The sizes of sella turcica increase from 1 to 20 years old; no significant increasing from 21 to 30 y.o. Differences in the sizes of sella turcica between males and females are not statistically significant. Keywords: Sella turcica
