  Results for the two-loop corrections to the Higgs-boson masses of the MSSM
with complex parameters of
$\mathcal{O}{\left(\alpha_t^2+\alpha_t\alpha_b+\alpha_b^2\right)}$ from the
Yukawa sector in the gauge-less limit are presented. The corresponding
self-energies and their renormalization have been obtained in the
Feynman-diagrammatic approach. The impact of the new contributions on the Higgs
spectrum is investigated. Furthermore, a comparison with an existing result in
the limit of the MSSM with real parameters is carried out. The new results will
be included in the public code $\texttt{FeynHiggs}$.
