The changes of the vacal cord in children with hoarseness have been said to be characterized by bilateral nodules of the vocal cords at the border of the anterior and the middle third.
The condition has often been referred as “Children's nodule” in Japan.
The author studied through the flexible fiberscope changes in the vocal cord in 30 children suffering from hoarseness for more than 3 months. Various findings of the vocal cords encountered were classified into 5 categories: They were
1. red and swollen type
2. edematous swollen type
3. unilateral nodule type
4. bilateral nodule type
and 5. motor disturbance type
In many of the children with hoarseness the author found retention of mucopurulent postnasal discharge in the vallecula. Radiological examination of the paranasal sinuses in those children revealed clounding of the sinuses in 73.3% of the cases. These findings may indicate that laryngeal pathology might be caused by paranasal sinus disease.
A laryngeal pathology termed as “sino-laryngitis” may exist in apposition with sino -bronchitis.
Vox & Larynx praemutatica theory developed by Iida in 1940 may explain some of the changes in the vocal cords in these children.
Disproportional growth between the vocal cord and the body may create changes in the vocal cord.
Lastly the author comments on environmental changes in industrial world as possible cause of laryngeal disease in children.
