[Percussional auscultation of frontal sinuses]

Percussional auscultation of the frontal sinuses is used for diagnosis of frontal sinusitides. Phonendoscope placed by the sinus walls auscultates sounds forming as a result of comparative percussion of the anterior sinus walls. Three main percussional tones are singled out. This method was employed for diagnosis in 48 patients with frontal sinusitis. The technique is easy to perform, safe and precise (90%). The trend in frontal sinusitides development can be followed up.
