Abstract: Introduction and importance: Conversion aphonia is a rare disease characterized by total loss of voice. It is more commonly reported in females than males, and its diagnosis is based on a comprehensive patient's clinical history, and assessment of vocal cords and other laryngeal structures using Fiberoptic laryngoscopy. Early diagnosis and phonation have a significant role in the treatment. Case presentation: A 12-year-old medically free male patient with unremarkable medical history and normal physical, social, cognitive and emotional developmental milestones presented to the otorhinolaryngology clinic with a sudden loss of voice for a duration of 3 days with absence of other associated symptoms. A comprehensive clinical history and general examination were within normal limits, and fiberoptic laryngoscopy revealed a normal-looking laryngeal structure with intact bilateral mobile vocal cords. A diagnosis of psychogenic aphonia was the most likely cause, so speech therapy concurrent with psychotherapy was the mainstay of treatment. Improvement of the patient condition noticed and he restored his speech 4 weeks after initiation of his treatment.
