The expansion of the hypopharynx by correction of glosso-larynx.
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.
