Abstract：Objective:To evaluate the clival recess with CT, in order to provide a basis for the design of transsphenoidal approach to clival region. Methods:A total of 93 patients were performed thin head scan with 64-slice spiral CT, and the media sagittal images were reconstructed in AW 4.2 workspace. The classification of clival recess was determined by the position relation between sphenoid sinus, clivus and hypophysis. The thickness in different part of clivus was compared between various types of clival recess.Results:The incidence of clival recess was 65%(60/93), which the sphenoid sinus were expanded to posterior edge of the hypophysis. The incidence of clival recess expanded below the sella turcica (subdorsum type), posterior to the sella turcica (dorsum type), or into the base part of occipital bone (occipital type) was 13%(12/93), 29%(27/93), and 23%(21/93) respectively. The clivus in the patients which the clival recess did not exist was thicker than other types. The upper and middle part of clivus in dorsum type and occipital type were thinner than other types. The lower part of clivus in the occipital type was thinner than other types.Conclusions:The evaluation of clival recess with CT is useful to design the individualized transsphenoidal approach to clival region.
