A new analysis, aimed to improve the current ANTARES measurement of the atmospheric neutrino oscillation parameters is presented. Two different track reconstruction procedures are combined in order to increase the sensitivity. Further, a novel method to estimate the neutrino energy is applied. A complete 3-flavour description of the oscillation probability through the Earth is used. By performing a two-dimensional fit of the event rate as a function of reconstructed energy and zenith angle, constraints on the oscillation parameters are derived.
