Princess Charlene of Monaco is playing a "waiting game" until she can see her family again.
The royal told South African radio host Mandy Wiener that she can't leave South Africa until the end of October after yet another medical procedure, reported People magazine.
"I cannot force healing," she said.
"Initially I was supposed to be here for 10 to 12 days. Unfortunately, I had a problem equalising my ears, and I found out through the doctors that I had a sinus infection and quite a serious one. So, it's taking time to address this problem that I'm having."
The princess, 42, had a sinus lift and bone graft in May to prepare for dental implants, with the surgery taking place before her travels to South Africa. But she began experiencing severe ear pain the following month as well as an infection, leading to complications.
