Objective tinnitus due to peritubal myoclonus. A case report.

A case of bilateral peritubal myoclonia with objective tinnitus in a 5-year-old child, under general anesthesia for phimosis surgery, is reported. After having shown the etiology, pathogeny and symptomatology of the peritubal myoclonic syndrome, the use of impedansometric research consisting of a spontaneous variation of 'compliance' is emphasized. The authors discuss the significance of differential diagnosis with the spontaneous variations of 'compliance' of vascular, respiratory and muscular origin.
