The paper describes results of ultrasound scanning in 32 patients with new formations in the lacrimal gland area, using a device "Ophthalmoocuscan, Model 200 A" (USA), with ultrasound fluctuation frequency--10 mHz, exposition time of probing impulse--0.2 microseconds. It was found that in case of lacrimal gland pathology the highest information value is received when the probe is placed at the superior external margin of the orbit and its scanning surface is directed on the site of the lacrimal gland projection. Characteristics of scanograms of different histologic types of new formations in the lacrimal gland area described: those of pleomorphic adenoma, adenocarcinoma, lymphoma, inflammatory pseudotumor, retention cysts. Typical scanograms were obtained in 78.1% of patients. The obtained characteristics of scanograms are recommended to be used in a complex with other methods for differential diagnostics of lacrimal gland new formations of different genesis. |
