A Case Repot of Chronic Unhealing Wound Related to Odontogenic Cutaneous Sinus Tract

Purpose: The odontogenic sinus and fistulous tracts is the most common draining sinus and fistulous tract of the head and neck region. These are often misdiagnoses by clinicions who are not familiar with cutaneous sinus, since most of patients do not have dental symptoms. Here we present two cases of odontogenic cutaneous sinus tract which have been diagnosed after excision of epidermal cyst. Methods: Two patients who presented with an odontogenic sinus tract draining to the skin at our institusion during the two years were enrolled in this study. We reviewed all the medical records of the patients and literature about odontogenic cutaneous sinus tract. Results: Odontogenic cutaneous sinus tracts of our cases were healed after treatment of periapical odontitis and extraction of the carious tooth. Conclusion: The cutaneous sinus tract of dental origin is well documented condition. But its diagnosis is not always easy unless the clinicians consider the possibility of its dental origin. An understanding of the pathogenesis of odontogenic cutaneous sinus tract will lead to early correct diagnosis and proper treatment without unnecessary surgery.
