Acute otitis media. An animal experimental study.

abstract：CONCLUSION:From aspect of fluid dynamics, expanding patients' nasopharyngeal coronal-sectional area to 48.3-54.7% of normal area will bring the airflow velocity back to normal in adenoidal hypertrophy children. It might provide a suggestion for adenoidectomy range selection and whether total resection is necessary. OB...
