The essential characteristic of Selective Mutism is the consistent failure to speak in social situations where speech is expected, despite the capacity of speaking in familiar places or situations. the child usually refuses to speak at school, but speaks normally and well at home. Most cases start at preschool age and have transitory course.

Psychotherapeutical interventions and selective serotonin reuptake inhibitors are considered first and second line treatments, respectively.

The purpose of this current report is to describe the successful treatment of selective mutism in a school-age boy.

This is a case report about a multidisciplinary approach on a boy who stopped talking at the age of 3, and restarted talking by the time he was 8 years old, after 1 year of treatment.

This study showed the improvement of the patient after he changed from a group therapy only to a combined psychiatric + individual psychotherapy + phonoaudiological treatment + family orientation + educational work (school).

This case of Selective Mutism had better and faster results with a multifocused treatment than single therapies only.
