Most of the passengers heavily injured in the Singapore Airlines (SIA) SQ321 flight affected by severe turbulence required operations due to brain and spinal cord injuries.

In a press conference in Bangkok, Thailand, on May 23, Samitivej Hospital's director, Adinun Kittiratanapaibool, said that while there are 20 other cases in the intensive care unit (ICU), there are currently no life-threatening casualties.

According to The Associated Press (AP), a spokesperson from Samitivej Srinakarin Hospital said other hospitals in Bangkok have deployed specialists to help carry out the procedures.
