Purpose:Articulation of rostrum of sphenoid bone with alae of vomer forms a schindylesis type of joint. The circumference of this joint, called sphenovomerine suture (SVS), is very important in establishing a reliable surgical field in the endoscopic transsphenoidal pituitary surgery. Because of its vital role in endoscopic transsphenoidal pituitary surgery, this radio-anatomical study was designed to establish the morphological properties of SVS.Methods:In this study, the authors examined SVS in 235 patients (121 females and 114 males) on the computed tomography images of the paranasal sinus and made 4 measurements to describe SVS.Results:The mean distance between superior margin of the upper labial philtrum and top of SVS was 6.660.43cm for females and 7.44 +/- 0.54cm for males. The distance between the top of SVS and dorsum sellae was 3.08 +/- 0.33cm for females and 3.19 +/- 0.32cm for males, the alae of vomer angle in the upper surface was 74.22 +/- 20.06 degrees for females and 74.23 +/- 19.68 degrees for males. The distance between the most lateral points of 2 alae of vomer was 0.99 +/- 0.17 and 1.01 +/- 0.19cm for females and males, respectively.Conclusions:For an easy and successful operation, removal of the SVS is very important as it will provide a better view of the sellar base and make the management of the surgical instruments easier in the wider safe surgical field thus created.
