Objective: The study aimed to evaluate the voices of the pediatric group with vocal cord nodules using acoustic, aerodynamic sound analysis methods. Material and Methods: This study included 35 subjects diagnosed with vocal cord nodule as a study group and 34 children as a control group between 6 and 12 years (Patient group average age 9.77±2.197, average age of healthy group 9.06±2.059). Voice analysis was evaluated using the Multi-Dimensional Voice Program (MDVP) and the Maximum Phonation Time (MPT) and s/z times were measured for aerodynamic evaluation. In addition, parents were required to fill out the Pediatric Voice Handicap Index to identify the social, emotional effects of voice deterioration on children. Results: Significant differences were found in MDVP data, MPT, and s/z ratio between subjects in the study and control group (p<0.05). S/Z ratios were increased while MPT values were shortened in the group with vocal cord nodules. It was observed that the study group scores were significantly higher in all parts of the index (p<0.05). Conclusion: Vocal cord nodules were found to occur mainly in male children with a higher and excessive intensity of speaking tendency. It was observed that the presence of vocal cord nodule adversely affected the voice quality. Because of the difficulty in the assessment of larynx with noninvasive methods in children, it is important to assess the acoustic characteristics of the voice by using objective and subjective methods. It was thought that voice analysis, aerodynamic assessment, and handicap index results are helpful in diagnosing for children with the vocal nodule.
