[Sinus aspergillosis after an endodontic treatment. Presentation of a clinical case]

Area of Science:

• Mycology
• Otolaryngology
• Dentistry

Background:

• Aspergillosis is a fungal infection typically affecting immunocompromised individuals.
• It often manifests as a deep mycosis, commonly involving the paranasal sinuses.
• However, cases in healthy subjects present challenges due to symptoms mimicking refractory chronic sinusitis.

Observation:

• A clinical case is presented involving a patient with chronic sinusitis symptoms.
• Radiological and histological examinations were crucial for diagnosis.
• A potential fungal entry point was identified as an oroantral communication.

Findings:

• The patient was diagnosed with sinus aspergillosis.
• The condition's origin was linked to a root canal procedure on a third upper molar.
• Penetration of root canal material may have facilitated fungal entry via oroantral communication.

Implications:

• This case highlights a potential iatrogenic cause of sinus aspergillosis in healthy individuals.
• It underscores the importance of considering dental procedures as a risk factor.
• Accurate diagnosis requires integrating radiological, histological, and clinical findings, especially in refractory sinusitis cases.
