The factors involved in controlling the vocal pitch are the tension, the mass, the length of the vocal cords and the subglottic pressure. Vocal pitch can be elevated surgically by increasing the stiffness or reducing the vibrating mass of the vocal cords. Recently, we experienced a case of 25 year-old female whose vocal pitch was elevated with radiofrequency surgery of right vocal cord on suspension laryngoscopy. Elevation of vocal pitch(134.11 to 144.73) was noted two months after operation. So we report this case with review of literature.
