Common pitfall of plastic surgeon for diagnosing cutaneous odontogenic sinus.

Dental origins are a common cause of facial cutaneous sinus tracts. However, it can be easily overlooked or misdiagnosed if not suspected by a surgeon who is not familiar with dental origins. Cutaneous odontogenic sinuses are typically nodulocystic lesions with discharge and are most frequently located on the chin or jaw. This article presents two cases of unusual cutaneous odontogenic sinus presentations, as deep dimpling at the middle of the cheek. The patients were undergone surgical excision of sinus tract and dimpling immediate before and after treatment of causal teeth and the lesions resolved without recurrence. Surgeons should consider dental origins of facial dimpling lesions with discharge and provide appropriate treatment.
