However, it is vital to remember the sites of contralateral crossing over of the various pathways and also the location of the pathways within the white matter as seen in cross section (Fig. 14).
A lesion of the spinothalamic tract will result in loss of pain-temperature sensation contralaterally, below the level of the lesion.
A lesion of the sensory area of the cerebral cortex may result in a contralateral deficit of all the above sensory modalities.
Unlike the other sensory pathways, which cross contralaterally, the spinocerebellar primarily remains ipsilateral.
Thus cerebellar lesions tend to produce ipsilateral malfunctioning, whereas cerebral lesions result in contralateral defects.،Because cysts often arise in the medial edge of a fold, contralateral reactive tissue thickening may occur, creating the erroneous appearance of bilateral lesions (eg, nodules).
A reactive vocal fold lesion is a generic term given to describe new tissue changes due to the known impact stress and mechani- cal irritation of a primary lesion (eg, polyp, cyst, or other mass) contralateral to the site.13 The lesion may appear to be thickened, rough, or as a concave depression to accommodate the convex bulge of the primary lesion (ie, "cup and saucer" effect).
noid meets a concave ulcerated area on the contralateral side.
Like external trauma, arytenoid dislocation also can occur fol- lowing external mechanical injury to the neck or throat or from difficult intuba- tion or extubation for surgery.55 When dislocated, the vocal process of the ary- tenoid cartilage may not move normally and may rest at a different vertical level than its contralateral pair.
The authors suggested that this tendency toward pitch elevation could reflect immedi- ate attempts to compensate for loss of CT-induced longitudinal tension, by recruiting other vocal fold tensors, such as the ipsilateral or contralateral thyro- vocalis belly of the thyroarytenoid (TA) muscle.
