Cutaneous Fistula of Tooth Origin: Report of Two Cases

Kim, Yoo Jin; Hwang, Kun; Lee, Se Il

Abstract

Cutaneous sinus tract of dental origin usually arises from chronic dental infections. These tracts usually appear as suppurative lesions of the chin or neck. Because many patients with this lesion do not have any complaints of oral symptoms, theses lesions are often diagnosed incorrectly and overlooked, and are also treated ineffectively. We report two cases of cutaneous fistula of tooth origin. One case on nasolabial fold is originated from the remaining tooth fragment of edentulous maxilla. Another case on the chin is originated from the cyst at the root of mandibular incisors. Treatment with removal of tooth fragment or cyst, and fistulous tract resulted in complete healing the lesions. This report emphasizes the importance of awareness of the possible dental origin of facial sinuses, despite their unusual location.
