Odontogenic sinusitis: developments in diagnosis, microbiology, and treatment

Area of Science:

• Otolaryngology
• Dentistry
• Infectious Disease

Background:

• Odontogenic sinusitis is frequently misdiagnosed as chronic rhinosinusitis (CRS).
• Conventional CRS treatments often fail for odontogenic sinusitis due to overlooked dental origins.
• Recent advancements necessitate clinician awareness of odontogenic sinusitis mechanisms, diagnosis, and treatment.

Purpose of the Study:

• To highlight the importance of recognizing odontogenic sinusitis.
• To inform clinicians about current understanding and management of odontogenic sinusitis.
• To improve patient outcomes by addressing distinct diagnostic and treatment considerations.

Main Methods:

• Review of current literature on odontogenic sinusitis.
• Analysis of diagnostic modalities including computed tomography (CT) and panoramic radiographs.
• Evaluation of treatment strategies involving dental source management and endoscopic sinus surgery (ESS).

Main Results:

• Odontogenic sinusitis often stems from periodontitis and iatrogenic causes.
• Key diagnostic indicators include unilateral nasal obstruction and foul nasal drainage; dental pain is often absent.
• Computed tomography (CT) is the gold standard for diagnosis, while panoramic radiographs are insufficient.
• Treatment requires addressing the dental source, often in conjunction with ESS.

Conclusions:

• Odontogenic sinusitis presents unique pathophysiology, microbiology, and treatment compared to CRS.
• Accurate identification of odontogenic sources enhances medical and surgical treatment efficacy.
• Improved diagnostic accuracy and targeted treatment strategies lead to better patient outcomes.
