We propose the modulation of dispersion to prevent collapse of planar pulsed beams that propagate in Kerr-type self-focusing optical media. As a result, we find a new type of two-dimensional spatiotemporal soliton stabilized by dispersion management. We have studied the existence and properties of these solitary waves both analytically and numerically. We show that the adequate choice of the modulation parameters optimizes the stabilization of the pulse.
