BACKGROUND: Odontogenic cutaneous sinus tracts are frequently misdiagnosed as cutaneous non-dental related pathologies, due to their lack of a typical morphology, their extraoral location, and the frequent absence of concomitant dental symptoms. An erroneous diagnosis may lead to long-lasting, invasive, and not resolutive surgical and medical treatments. METHODS: Four patients referred to our department lamenting the presence of a recurrent facial cutaneous sinus tract. They all had already had different wrong diagnoses and were treated with not resolutive therapies or surgeries. After a clinical and radiographical oral examination, the cutaneous fistulas were found to have a dental etiology, and the extraction of the compromised tooth was performed. RESULTLTS: One week after the tooth extraction, all the patients presented good healing of the intraoral mucosa. At the long-term follow-up in all four cases, the definitive closure of the extraoral sinus tract and a reduction of the scar was found. CONCLUSIONS: If a facial sinus tract is present, the odontogenic etiology should always be considered, since it can easily bring to the correct diagnosis, leading to a rapid resolution of the fistula. Once the dental origin has been confirmed, the suggested treatment for a conclusive resolution of the cutaneous sinus tract is the endodontic treatment or the extraction of the affected tooth.

Abstract
BACKGROUND: Odontogenic cutaneous sinus tracts are frequently misdiagnosed as cutaneous non-dental related pathologies, due to their lack of a typical morphology, their extraoral location, and the frequent absence of concomitant dental symptoms. An erroneous diagnosis may lead to long-lasting, invasive, and not resolutive surgical and medical treatments. METHODS: Four patients referred to our department lamenting the presence of a recurrent facial cutaneous sinus tract. They all had already had different wrong diagnoses and were treated with not resolutive therapies or surgeries. After a clinical and radiographical oral examination, the cutaneous fistulas were found to have a dental etiology, and the extraction of the compromised tooth was performed. RESULTLTS: One week after the tooth extraction, all the patients presented good healing of the intraoral mucosa. At the long-term follow-up in all four cases, the definitive closure of the extraoral sinus tract and a reduction of the scar was found. CONCLUSIONS: If a facial sinus tract is present, the odontogenic etiology should always be considered, since it can easily bring to the correct diagnosis, leading to a rapid resolution of the fistula. Once the dental origin has been confirmed, the suggested treatment for a conclusive resolution of the cutaneous sinus tract is the endodontic treatment or the extraction of the affected tooth.File | Dimensione | Formato | |
