Congenital anomalies of the external ear are rare, and can have negative effects on children due to unaesthetic appearance and repeated infection. Surgical management is required to correct the deformity. Of the external ear deformities, congenital fistulae are rare and manifest as blindly ending narrow tubes, sometimes mere pits or dimples. The fistular opening can be located in various regions of the periauricular area. The present case involved 3-year-old girl with two congenital openings at the intertragic incisura and the middle of the free border of ear lobule, which caused frequent odorous discharge. A fistulogram showed that the two openings were interconnected via a fistular tract. The patient underwent fistulectomy under general anesthesia. The author reports this case with review of a literature. (J Clinical Otolaryngol 2007;18:125–127)
