Reports first surfaced last Wednesday that members of Cisse's family had perished in the tragedy last Sunday.
At least 399 passengers drowned when the ferry capsized and Cisse learned 11 of his family were among the dead on Tuesday.
But the Senegal captain kept the heartache under wraps until Friday and figured for Birmingham in Saturday's victory at West Ham.
Immediately after the clash at Upton Park, Cisse boarded a plane to his homeland but paid tribute to those who died.
"I had 11 members of my family on that boat. Cousins, an uncle and aunt," revealed Cisse.
"This victory I dedicate to their memory. Now I have done my job and must go home."
Blues boss Steve Bruce has informed Cisse there is no rush for his summer signing to return to St Andrews.
"For Aliou to go out there and play like he did here is a massive tribute to the man," acknowledged Bruce.
"To show that sort of mental strength takes incredible courage and it's irrelevant when he comes back.
"I've told him to stay away for however long it takes to get over the loss of so many family members.
"He never mentioned what had happened all week, until he was arranging his flight home on Friday.
"I'd got a whisper about it on Thursday and asked him what had happened.
"Yet he told me he just wanted to concentrate on the game. It certainly puts football into perspective."
