ABSTRACT
Anatomical variations in the shape and dimension of the dorsum sellae and posterior clinoid process are common. Most textbooks describe its shape as a median rectangular plate, a square plate, or a transverse ledge on a slope behind the sella turcica (hypophyseal fossa). This work aims to study the dorsum sellae of human skull. One hundred and twenty five dried adult human skulls, irrespective of age, were used for the study. Detailed features of the dorsum sellae were noted and classified into five types crest like, thin plate, frail quadrilateral plate, heavy square plate, thick elongated plate. Fusion of the posterior and middle clinoid processes in one (unilateral) and all the clinoid processes (anterior, middle, and posterior) in three skulls (unilateral in one, bilateral in two) were also noticed. Findings are discussed in the light of the literature.
RESUMEN
Son frecuentes las variaciones anatómicas de la forma y dimensión de dorsum sellae y de los procesos clinoides posteriores. La mayoría de los textos describen su forma como una placa rectangular mediana, una placa cuadrada, o un plano transversal en una pendiente detrás de la sella turcica (fosa hipofisaria). Este trabajo tiene como objetivo estudiar el dorsum sellae en cráneo humano. Para el estudio se utilizaron 125 cráneos humanos adultos secos, de diferentes edades. Se observaron características detalladas de dorsum sellae y se clasificaron en cinco tipos cresta, al igual que la placa delgada, lámina cuadrilátera, placa cuadrada gruesa, placa alargada gruesa. En tres cráneos se observó fusión de la parte posterior y los procesos clinoides intermedios (unilateral) y los procesos clinoides (anterior, medio y posterior) (unilateral en uno de ellos, bilateral en dos). Los resultados se discuten en consideracion de la literatura.
