The Miss Universe 1979 pageant and awards ceremony was held in Perth, Australia on July 19.
When she won the Miss Venezuela 1979 title, her second runner-up Maria Fernanda Ramirez refused to acknowledge the results; her family then attacked the jury, with her mother and brother physically accosting the judges.
Sayalero recovered enough of her legendary poise to take the Miss Universe title in Australia, but immediately after the live telecast ended the stage collapsed as too many journalists and photographers stormed to get a photograph of the new queen. She managed to save another contestant from falling into the gaping hole left in the middle of the set, although several unfortunate women including Miss Turkey and Miss Brazil were injured.
Her name has become synonymous with beauty among Spanish language speakers, not only in Venezuela. In the 1980s, many girls were named Maritza, especially if the family name was the not uncommon Fernandez.
At least one ship was named in her honour, Maritza Sayalero.
