The contest was held for the second consecutive time at the Salon Teotihuacan of the Centro Internacional de Convenciones Acapulco of Acapulco, Guerrero, Mexico on September 19, 1998.

Thirty-two contestants of the Mexican Republic competed for the national title, featuring the first back to back victories in Nuestra Belleza Mexico history: Silvia Salgado from Nuevo León was crowned by outgoing Nuestra Belleza México titleholder Katty Fuentes, also from Nuevo León.

Salgado competed at Miss Universe 1999 in Trinidad and Tobago where she was a Semi-finalist in the Top 10.

The Nuestra Belleza Mundo México title was won by Vilma Zamora from Guanajuato, who later competed at Miss World 1998 in Seychelles.

Zamora was crowned by outgoing Nuestra Belleza Mundo México titleholder Blanca Soto.
