[Sonographic studies in odontogenic maxillary sinus diseases].

Abstract

Clinical diagnostic information was analysed and compared with conventional x-ray and B-scan examination in 90 patients with maxillary sinus diseases of dental origin. In certain diseases (sinusitis, cysts) the ultrasonic sonography offered little additional clinical-relevant information. On the other hand this modern noninvasive, picture yielding and ever reproducible method is predestined for objective confirmation of the late complaint after maxillary sinus operation. But the high apparatus technical investment limits its application in large scale.
