title: Facial cutaneous sinuses of dental origin - a diagnostic challenge.
abstract: It is common for practitioners to misdiagnose the cause of facial cutaneous sinus tracts, failing to recognise that many have an odontogenic cause. Chronic infection around the apex of a dental root can drain to the mouth or less commonly to the skin via a sinus tract. Dental symptoms are not always present and this confuses the clinical picture further. Failure to identify an odontogenic cause may result in unnecessary and ineffective treatment. Elimination of dental infection via tooth extraction or root canal treatment leads to resolution of the cutaneous sinus. We present a series of cutaneous draining sinuses of dental origin that resolved rapidly following dental treatment and hope to highlight the importance of including odontogenic infection in the differential diagnosis of such a lesion in the head and neck.
