[Aerodynamic aspects in the concept of treatment in chronic sinusitis maxillaris (author's transl)].
Hitherto the conditions of air flow had been neglected in the concept of treatment of chronic inflammation of the maxillary sinus. Our experimental and clinical studies with measurement of airflow and temperature yielded several aspects of clinical importance as follows: The maximum size of the operated opening in the antral wall should be more than 10 X 10 mm. to achieve optimal ventilation. If there are two meatal open windows, the operated fenestration in the inferior meatus, for example, and the ostium maxillaris in the middle meatus, an "aerodynamic short circuit" arises. This results in insufficient ventilation. Large fenestrations have the same effect.
