Management of extraoral sinus via nonsurgical root canal treatment

Abstract

Cutaneous sinus tracts of dental origin have been well-documented in the medical literature. However, these lesions continue to be a diagnostic dilemma. A review of several reported cases reveals that patients have had multiple surgical excisions, radiotherapy, multiple biopsies, and multiple antibiotic regimens, all of which have failed, with a recurrence of the cutaneous sinus tract, as the primary etiology was dental that was never correctly diagnosed or addressed. This case report demonstrates the healing of an extraoral draining sinus by means of conventional nonsurgical root canal treatment.
