An unusual presentation of cutaneous odontogenic sinus in midfacial region- a case series

Clinical presentation of extra oral sinus tracts of endodontic origin are mostly confused with a wide variety of dermatological lesions. Misdiagnosis of the lesion leads to unnecessary treatment, further results in healing failure and recurring lesions over a period of time. Hence, a dental aetiology must be considered for any cutaneous sinus tract involving the face or neck. Once the correct diagnosis is made, definitive treatment, either through root canal therapy or tooth extraction, to eliminate the source of infection is done. This case series demonstrates a successful endodontic treatment of extra oral draining sinus tract.
