Princess Kalina's altered nose appearance stems from a series of health issues rather than cosmetic surgery mishaps. Initially, she experienced a seemingly minor injury that led to broken teeth from a fall. The dental repairs introduced a severe infection in her jaw, which required extended treatment and a complex operation to prevent further spread to other parts of her body. The lasting impact of this infection has notably affected the appearance of her nose.
Apparently there are also more normal pictures of her and one that's way worse than this or the op, so my guess is some sort of plastic surgery obsession developing in more recent times
