  In this paper, we derive in a novel approach the possible textures of
neutrino mass matrix that can lead us to maximal atmospheric mixing angle and
Dirac CP phase which are consistent with the current neutrino oscillation data.
A total of eleven textures are thus found. Interestingly, the specific texture
given by the $\mu$-$\tau$ reflection symmetry can be reproduced from one of the
obtained textures. For these textures, some neutrino mass sum rules which
relate the neutrino masses and Majorana CP phases will emerge.
