Endoscopic and Phoniatric Evaluation in Singing Students.

In To analyze laryngostroboscopic findings and ENT/phoniatric examination results in a group of singing students and in a control group of non-singing subjects to emphasize the importance of ENT/phoniatric examination and of laryngostroboscopy before taking up singing. 56 singing students and 60 healthy euphonic non-singer volunteers were recruited. In each subject a perceptual assessment and a self-assessment (VHI) of the voice were performed. The singing students filled out the Singing-VHI. All subjects underwent flexible fiberoptic endoscopy and laryngostroboscopy. All subjects were evaluated through the Reflux Symptom Index (RSI) and the Reflux Finding Score (RFS). At laryngostroboscopy, 60.7% of students presented pathological findings, versus 20% of controls (P < 0.0001). Incomplete glottic closure (35.7% vs. 13.3%), supraglottic hypertonus (16.1% vs. 5%), organic lesions (bilateral nodules, cysts, sulcus vergeture) (17.9% vs. 3.3%), posterior erythema (16.1% vs. 5%) and laryngeal edema (14.3% vs 3.3%) were more frequent in the students. The most common symptoms in singers were phonasthenia (37.5 % vs 6.7%; P =  0.0001) and mucus sensation (17.9% vs. 5%, P = 0.03). S-VHI showed higher values in students with pathological laryngostroboscopy (P < 0.0001). Finally, average RSI and RFS were higher in students. Due to the high percentage of organic and functional voice disorders in singing students, it would be desirable that every subject who is going to start singing underwent an ENT/phoniatric investigation with videostrobolaryngoscopy to ascertain vocal folds healthy condition.
