title: Descriptive Analysis of Sphenovomerine Suture and Its Importance in Neurosurgery.
abstract: OBJECTIVE
  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 6.66 ± 0.43 cm for females and 7.44 ± 0.54 cm for males. The distance between the top of SVS and dorsum sellae was 3.08 ± 0.33 cm for females and 3.19 ± 0.32 cm for males, the alae of vomer angle in the upper surface was 74.22 ± 20.06° for females and 74.23 ± 19.68° for males. The distance between the most lateral points of 2 alae of vomer was 0.99 ± 0.17 and 1.01 ± 0.19 cm 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.
