The width of the hypopharynx and oropharynx before and after the operation correction of glosso‐larynx (CGL) was compared by cranial X‐ray film. After the operation, the hyoid bone was seen to have moved downward, and the cranial bone was observed to have rotated forward. As a result, the hypopharynx and the oropharynx were expanded. Expansion of the hypopharynx resulted in the decreased resistance of flow decreased and the increased in airflow.
