Diagnosis and treatment of odontogenic cutaneous sinus tracts of endodontic origin: three case studies

B. Pasternak-Júnior
Abstract Aim, To describe three cases of extraoral sinus tracts, related to infected teeth, which were initially misdiagnosed as skin lesions and inappropriately treated. Summary, The extraoral sinus tracts were initially misdiagnosed as skin lesions. Dermatological surgery was performed and antibiotics prescribed but the lesions did not resolve. Then, a dental cause was sought, and identified. Endodontic intervention resulted in resolution of the problem, confirming the initial misdiagnosis. Key learning points ,,Dermatologists and other medical practitioners should be aware that dental extraoral sinus tracts can be confused with skin lesions. ,,A dental aetiology, as part of a differential diagnosis, should be kept in mind with oro-facial skin lesions. ,,If an extraoral sinus tract is of endodontic origin, then elimination of infection through effective endodontic treatment will lead to resolution of the sinus tract. ,,Early correct diagnosis can prevent unnecessary and ineffective antibiotic therapy and/or surgical intervention.

Conservative treatment of patients with periapical lesions associated with extraoral sinus tracts

Janir Alves Soares phd
Abstract This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. [source]
