[Examination of function by scintillography after dacryocystorhinostomy (author's transl)].

By means of a radiotracer 99mTc-pertechnetate the function of the lacrimal system was determined after dacryocystorhinostomy. The results of the examinations demonstrate that the function of the lacrimal system is more quickly normalized if the lig. canthi int. is fixed to the periosteum of the os lacrimale.
