Roentgen examination of maxillary sinus, antral puncture and irrigation--a comparative study

The various radiological findings of maxillary sinus were compared to those at antral puncture and irrigation in patients with chronic maxillary sinusitis. It was noted that roentgen findings of opacity and fluid level of the maxillary sinus are definite evidences of sinus infection and a mucosal thickening is not an indication of sinus infection.
