[Radionuclide research on the bones using 99mTc-phosphonium in ear diseases]

The state of the skeleton was studied in 62 patients with otosclerosis to investigate diagnostic potentialities of 99mTc-phosphonium, of them in 34 patients the diagnosis was confirmed at operation. 38 patients suffered from acute and chronic otitis media, 18 from cochlear neuritis, 4 from Meniere's disease. Scintigraphic imaging was processed quantitatively. When comparing skeleton images of the patients and persons of the control group (25 persons) it was established that radionuclide investigation of the bones with 99mTc-phosphonium of patients with hypoacusis was a highly informative method for determination of a degree of disorder of the temporal bone. Systemic bone affection was observed in otosclerosis. Considerable RP fixation was found in patients with an active course of the otosclerotic process. A group of patients in whom hypoacusis was combined with disorder of the osseous capsule, was detected among the patients with acoustic neuritis. Scintigraphy with 99mTc-phosphonium was recommended as an obligatory diagnostic procedure for patients with hypoacusis.
