We show that, in the 3-3-1 model with right-handed neutrinos, small neutrino masses and large lepton flavor violating processes such as \ensuremathμ\ensuremath→3e and \ensuremathμ\ensuremath→e\ensuremathγ can be obtained by just introducing an additional Higgs sextet. In the limit of vanishing of the Yukawa interaction among Higgs and lepton triplets (h^\ensuremathν=0), the decay \ensuremathμ\ensuremath→3e strongly depends on the neutrino-mass patterns, but the \ensuremathμ\ensuremath→e\ensuremathγ almost does not. The neutrino masses are not constrained by such processes in the cases of h^\ensuremathν\ensuremath≠0.
