Abstract: We propose a seesaw scenario that possible corrections to the tribimaximal pattern of lepton mixing are due to the small phase splitting of the right-handed neutrino mass matrix. We show that the small deviations can be expressed analytically in terms of two splitting parameters (δ1 and δ2) in the leading order. The solar mixing angle θ12 favors a relatively smaller value compared to zero order value (35.3°), and the Dirac type CP phase δ chooses a nearly maximal one. The two Majorana type CP phases ρ and σ turn out to be a nearly linear dependence. Also a normal hierarchy neutrino mass spectrum is favored due to the stability of perturbation calculations.
