A persistent oronasal sinus tract of endodontic origin

Area of Science:

• Dentistry
• Oral and Maxillofacial Surgery

Background:

• Extraoral sinus tracts of endodontic origin present a diagnostic challenge, often mimicking other facial and neck pathologies.
• These tracts arise from dental infections and can manifest in various locations.

Observation:

• A specific case of a persistent oronasal sinus tract of endodontic origin was observed.
• The lesion presented a diagnostic dilemma due to its location and persistence.

Findings:

• Endodontic therapy is the primary treatment for extraoral sinus tracts.
• In this case, conventional endodontic treatment was insufficient, necessitating surgical intervention.
• Surgical removal of the lesion led to complete healing of the persistent oronasal sinus tract.

Implications:

• Accurate diagnosis is crucial for effective management of endodontic sinus tracts.
• While endodontic treatment is often curative, surgical intervention may be required for refractory cases.
• This case highlights the importance of considering surgical options when endodontic therapy fails to resolve persistent sinus tracts.
