We study the vortex spatiotemporal optical solitons in graded-index kerr medium. We consider the propagation of a pulse in inhomogeneous dispersive nonlinear optical fibers and we investigate the possibility of forming bistable spatiotemporal vortex solitons. We solve the multidimensional nonlinear Schrödinger equation by using a variational approach. The results show that vortex bistable spatiotemporal solitons can be stabilized under certain conditions.
