Construction of stereotactic data set and projection regression analysis of Heschl's gyrus

ObjectiveTo construct the stereotatic localization data set and its plane projection regression equation of the Heschl's gyrus based on the AC-PC localization system.

MethodsThe transverse tomography data of 30 healthy adults were imported into Photoshop CS software package by format transformation.After strict image registration, a three-dimensional sitting system with AC-PC midpoint as the origin was established.From the side point of Heschl's gyrus as the starting point, the X and Z values of the coordinates of the point were measured and recorded, and the Y value was the product of the number of layers between the image layer and AC-PC plane and interlayer spacing.The stereotactic data set in a three-dimensional coordinate system of Heschl's gyrus was constituted by the coordinate values of all sampling points.The projection scatter plot was made by Excel table, and the spatial fitting plane regression equation on the transverse, sagittal and coronal planes was obtained by SPSS 22.0 statistical software.

ResultsThere was no statistical significance in the X coordinate values between left and right sides of the transverse temporal gyrus in males(P>0.05), while there was statistical significance in the Z coordinate values between left and right sides(P < 0.05).There was no statistical significance in the X and Z coordinate values between left and right sides of the transverse temporal gyrus in women(P>0.05).The regression equation of Y value to X value of transverse plane in medial margin of transverse temporalis gyrus in right side and left side were \mathop Y\limits^ \wedge =29.3-6.48X+0.25X²-0.002 5X³(P < 0.01) and \mathop Y\limits^ \wedge =-108-4.73X-0.05X²(P < 0.01), respectively.The regression equation of Z value to Y value of sagittal plane in medial margin of transverse temporalis gyrus in right side and left side were \mathop Z\limits^ \wedge =-0.8-0.35Y-0.004Y²(P < 0.01) and \mathop Z\limits^ \wedge =0.1-0.2Y+0.008 64Y²-0.000 569Y³(P < 0.01), respectively.The regression equation of Z value to Y value of coronal plane in medial margin of transverse temporalis gyrus in right side and left side were \mathop Z\limits^ \wedge =54.8-2.63X+0.03X²(P < 0.01) and \mathop Z\limits^ \wedge =58.9+2.82X+0.03X²(P < 0.01), respectively.

ConclusionsIt has great clinical value to construct stereotaxic data sets of the Heschl's gyrus and linear regression equation for stereotaxic neurosurgery, interventional radiotherapy and minimally invasive neurosurgery in the lesions of the Heschl's gyrus and its adjacent areas.It also great significance to reveal the morphological rule of the development of the heschl's gyrus.
