Abstract

AbstractA 16‐year‐old‐girl had a six‐month history of sialotorrhea. Lipiodol sialography of the right parotid revealed overflow of Lipiodol into the right external acoustic meatus. Surgical exploration that left the facial nerve intact disclosed a branchiogenic anomaly confirmed at histologic examination—a lesion that extended parallel to the external acoustic meatus—and aplasia of the pars tympanica of the right petrosal bone. It is concluded that the branchiogenic anomaly is a first‐branchial‐cleft anomaly (type I according to Work); the aplasia of the pars tympanica ossis temporalis remains unexplained. The sialotorrhea probably resulted from an infection of the branchiogenic cyst.
