We analyze the leptonic sector in the left-right symmetric model dressed with a (Z{sub 2}){sup 3} discrete symmetry which realizes, after weak spontaneous breaking, a small broken {mu}{r_reversible}{tau} symmetry that is suggested to explain observable neutrino oscillation data. {mu}{r_reversible}{tau} symmetry is broken at tree level in the effective neutrino mass matrix due to the mass difference m(tilde sign){sub {tau}{ne}m}(tilde sign){sub {mu}} in the diagonal Dirac mass terms, whereas all lepton mixings arise from a Majorana mass matrix. In the limit of a small breaking we determined {theta}{sub 13}, and the deviation from the maximal value of {theta}{sub 23}, in terms of the light neutrino hierarchy scale, m{sub 3}, and a single free parameter h{sub s} of the model.
