Abstract

Objectives Stroboscopy is considered the most appropriate tool for evaluating the function of the vocal folds but may harbor significant limitations in children. Still, direct laryngoscopy (DL), under general anesthesia, is regarded the “gold standard” for establishing a diagnosis of vocal fold pathology. The aim of the study is to examine the accuracy of preoperative rigid stroboscopy in children with voice disorders. Study Design This is a retrospective study. Methods A retrospective study was conducted on a cohort of 39 children with dysphonia, aged 4 to 18 years, who underwent DL. Twenty-six children underwent rigid stroboscopy (RS) prior to surgery and 13 children underwent fiber-optic laryngoscopy. The preoperative diagnoses were matched with intraoperative (DL) findings. Results DL was found to contradict preoperative evaluations in 20 out of 39 children (51%) and in 26 out of 53 of the findings (49%). Overdiagnosis of cysts and underdiagnosis of sulci were noted in RS compared to DL. The overall rate of accuracy for RS was 64%. Conclusions The accuracy of rigid stroboscopy in the evaluation of children with voice disorders was found to be similar with previous reports in adults.
